Variable speed pumps are useful in pool, spa, and other aquatic applications to meet the variety of demands in any particular application. For example, in some instances a variable speed pump can be used to pump water to a number of features related to the particular application. With respect to a pool or spa, the variable speed pump can pump water to water jets, waterfalls, fountains, pool filtration equipment, pool vacuums, spillways and the like. Varying the speed of the pump can assist the filtration of the fluid, such as water, being moved by the pump for the aquatic application. For example, the aquatic application can include one or more filtration elements such as a strainer basket, diatomaceous earth filter, a sand filter, cartridge filter, hollow fiber membrane filter or the like. Thus, by varying the speed of the pump, the level of water filtration can be controlled. In this way, the pump can provide higher levels of filtration at higher speeds either when the demand for filtration is high or as part of schedule. When less filtration is needed, the pump can run at a lower speed to move less water to and from the aquatic application. In some instance, the variable speed pump may be operated at alternating high and low speeds in order to provide sufficient filtration while also consuming the least amount of power practicable.
While conventional variable speed pumps provide many benefits, they are also subject to various drawbacks. Some conventional pumps provide less sophisticated interfaces and control features in order to control the function of the pump. Accordingly, more sophisticated and versatile control mechanisms would be useful. In some instances, it would be useful to provide a variable speed pump that was capable of being highly integrated into a system of control mechanisms. Aside from controllability, conventional variable speed pumps lack in a number of structural areas. For example, some conventional pumps encounter issues with corrosion at the interface between the motor and the wet-end of the pump. To provide additional examples, pump positioning and motor heating can also present problems in conventional variable speed pumps. Accordingly, it would be useful to provide an improved variable speed pump for use in aquatic applications.

In some forms, the method includes automatically initiating the updated pump operation schedule, wherein the updated pump operation schedule includes one or more of an updated pump speed, an updated pump flow rate, or an updated pump operation time based on the system friction curve.
In some forms, the system friction curve is generated from a total dynamic head value based on a third pressure sensor positioned on the suction side of the pump, the first pressure sensor installed on the discharge side of the pump, and a flow value measured by the flow meter.

As explained above, it would be useful to provide an improved variable speed pump for an aquatic application. More particularly, a variable speed pump that is fluidly coupled to a fluid circuit of an aquatic application in order to move a fluid such as water to and from an aquatic application.
The variable speed pump 100 is designed to move water through the fluid circuit to and from the aquatic application. In some forms, one or both of the inlet 112 and the outlet 114 include a check valve, e.g., a suction-side check valve and a return/pressure-side check valve, to prevent back flow, to isolate the pump for maintenance, and/or to carry out the preliminary steps of a pump priming process. The wet end 104 contains a volute or strainer pot 116 within which an impeller 118 and a strainer basket 115 are located. The wet end 104 interfaces with the power end 106 via a seal plate 120, which can include an 0-ring 122 or other sealing structure to prevent water from seeping out of the pump 100 from the wet end 104. The motor 110 also includes a motor flange 172 that is coupled to the seal plate 120.
The power end 106 includes the motor 110, a variable speed drive 130 provided adjacent and above the motor 110, and an onboard controller 134. In some forms, the motor flange 172 and/or the body of the motor 110 includes a drive connection port 108 through which the motor 110 is electrically connected to the drive 130. As such, the drive 130 is removable and replaceable by disconnecting the drive 130 from the drive connection port 108. The motor 110 includes a drive shaft 138 that extends through the seal plate 120 and is coupled to the impeller 118. Accordingly, the motor 110 produces torque in the drive shaft 138 to rotate the impeller 118, which moves water in through the inlet 112 and out through the outlet 114 of the wet end 104. The variable speed drive 130 is in electrical communication with the onboard controller 134 and the motor 110. In some instances, the variable speed drive 130 provides substantially infinitely variable speed control of the motor 110.
The onboard controller 134 can be coupled to the power end 106 of the pump 100 and can be configured to provide user control of the variable speed drive 130. In some instances, the controller 134 is positionally adjustable with respect to an outer housing of the power end 106. In some instances, the onboard controller 134 includes a USB or other known electrical connection port to which a programming device can be attached to upload or update the software installed on the controller 134. In some other embodiments, the software installed on the controller 134 can be updated via wireless over-the-air updates. The outer housing of the power end 106 can comprise multiple parts. For example, the outer housing can be provided in the form of a motor cover or shroud 146, an end cover 150, a drive cover 154, and a user interface cover 164. The motor cover 146 can be provided with various venting arrangements to provide appropriate cooling of the drive 130 and the motor 110. The configuration of the outer housing illustrated in
Each of the elements of the electrical communication assembly 168, as well as the antenna 144, are electrically coupled to the onboard controller 134, which includes a main circuit board 228 (see
As illustrated in
As mentioned above, the IO expansion module 160 can provide multiple relay terminal blocks 196 and digital input terminals 208. In some instances, one or more relays 198 are electrically coupled to the main circuit board 228 and each of the relay terminal blocks 196 to control the delivery of incoming and outgoing 115 VAC or 230 VAC. The relays 198 can be configured to provide the same or different amperage limits, and the relays 198 can be activated at the same time or at different times. For example, one of the relays 198 can provide a higher current limit, and one of the relays 198 can provide a lower current limit. As a non-limiting example, the left-most relay 198 can be rated to provide a maximum of 8 A and the right-most relay 198 can be rated to provide a maximum of 30 A.
In some instances, the left-most relay 198 can be rated to provide a maximum of 5 A and the right-most relay 198 can be rated to provide a maximum of 16 A. In some forms, the right-most relay terminal block 196 can be electrically coupled to two of the relays 198 while the left-most relay terminal block 196 can be electrically coupled to a third one of the relays 198 or vice versa. In this way, a variety of devices can be connected to, powered by, and controlled through, an electrical connection with the relays 198. Each relay terminal block 196 includes four terminals, two of which can be electrically coupled to an auxiliary power supply and/or circuit breaker and two of which can be electrically coupled to the relayed auxiliary device(s) 174. Examples of auxiliary devices 174 that can be electrically coupled to the relay terminal blocks 196 include, for example, lighting assemblies, salt chlorine generators, water quality monitors, booster pumps, single speed pumps, spa blowers, chlorinators, pool vacuums, water features, fountains, heaters, or other pool accessories and equipment. In some forms, the pump 100 can include a combination of data and power transmission instead of, or in addition to, the relays 198. For example, rather than being coupled to the relays 198, any of the auxiliary devices 174 can be coupled via a wired connection to a control port of the pump 100 that provides power to the auxiliary devices 174 as well as two-way communication. In some forms, all of the data transmission and communication between the pump 100 and the auxiliary devices 174 occurs wirelessly.
The digital input terminals 208 can provide an electrical connection between the pump 100 and a mid-level automation device 180. The digital input terminals 208 can provide a plurality of speed control or flow control terminals, such that the mid-level automation device 180 can cause the pump 100 to run at a plurality of pump speeds, e.g., revolutions per minute (RPM) or volumetric flow rates, e.g., gallons per minute (GPM). In some instances, four or more pump speeds or flow rates can be initiated by the mid-level automation device 180. The main circuit board 228 can be programmed such that when the automation device 176 is electrically connected to the RS-485 terminal block 170, the digital input terminals 208 are ignored. In some forms, when the automation device 176 is electrically connected to the RS-485 terminal block 170, the relays 198 are deactivated such that there can be no pass-through control of the auxiliary devices 174 from the automation device 176. In some forms, pass-through control of the auxiliary devices 174 from the automation device 176 is simply absent, e.g., not a provided functionality. In some forms, however, the automation device 176 can control all aspects of the operation of the pump 100 as well as all aspects of the operation of the auxiliary devices 174, providing pass-through control of auxiliary devices 174 that are connected to the relays 198 from the automation device 176. For example, if a lighting assembly is connected to the pump 100, and the pump 100 is connected to the automation device 176, the automation device 176 can send instructions that will implement lighting assembly logic to turn the lighting assembly on/off, light up in different colors, or provide various animations.
The main circuit board 228 may be provided with one or additional components provided in the form of electronics, software, sensors, actuators, and/or network connectivity to collect and exchange data. In some embodiments, the main circuit board 228 may send and/or receive data transmissions over a local area network (LAN), a wide area network (WAN), and/or another communication network using any suitable communication protocol. For example, the main circuit board 228 may communicate over the LAN with a local server computing device, such as in a private network where transmitted data to/from the main circuit board 228 is isolated from the internet or another WAN, at least until the data is processed by the local server. In some embodiments, (a) local server(s) may be operated at the same location as the pump 100, such as at a residence or business. A user device may also be connected to the LAN in order to access the data; alternatively, IP connectivity may be used, connecting the LAN and/or the local server(s) to the Internet or another WAN, so that local and/or remote user devices can access the local server.
Further, the main circuit board 228 may connect directly or through a router, gateway, base station, etc. (shown as wired/wireless router or gateway), to the WAN in order to communicate with cloud-based computing resources. Such an environment provides a bi-directional, direct-to-cloud communication between the main circuit board 228 and one or more application and/or hosting servers. In some embodiments, the main circuit board 228 may communicate with and directly use the resources of one or more physical, remote server computing devices, which may be deployed in one or more data centers (for example) in a particular geographic location or dispersed throughout several geographic locations. In other embodiments, the remote physical servers may cooperate to provide virtualized computing resources that can be allocated for use by, for example, an authorized user of a computing resource service provider. In various embodiments, the server may be a virtual server or may represent a cluster of servers. In some forms, the server can be confirmed to store and provide data analytics associated with any variety of operational, maintenance, scheduling, or other parameters related to the pump 100 over time, such as flow rates, pump speeds, temperatures, pump power consumption value, e.g., kilowatt-hours over a period of time such as a week, system pressure, the total dynamic head, and total gallons pumped.
Non-limiting examples of communication protocols include: a wired (e.g., CAT5, USB) connection to a router and any TCP/IP protocol for wired connections; a wireless connection to a router, and wireless TCP/IP protocols such as Wi-Fi or MQTT; and/or direct communication with another IoT device using the above wireless protocols or other suitable protocols such as Bluetooth or Wi-Fi direct. More generally, a communication network can include a Wi-Fi network (e.g., an 802.11x network, which can include one or more wireless routers, one or more switches, etc.), a peer-to-peer network (e.g., a Bluetooth network, a ZigBee® network, a Z-Wave® network, a proprietary RF connection, etc.), a cellular network (e.g., a 3G network, a 4G network, a 5G network etc., complying with any suitable standard, such as CDMA, GSM, LTE, LTE Advanced, WiMAX, etc.), a wired network, an EnOcean® network, etc. In some embodiments, the communication network can be a LAN, a WAN, a public network (e.g., the Internet), a private or semi-private network (e.g., a corporate or university intranet), any other suitable type of network, or any suitable combination of networks.
In some embodiments, the antenna 144 is configured to send and/or receive wireless signals, such as signals for communicating over Wi-Fi, Bluetooth, ZigBee, Z-Wave, free-space optical, etc. In some such embodiments, the antenna 144 can receive signals from the wireless gateway module and can transmit the signals to the main circuit board 228 for processing into commands. Additionally, or alternatively, the antenna 144 can send signals generated by the main circuit board 228 to the wireless gateway/router. In some embodiments, the main circuit board 228 can communicate with server(s) and/or other IoT devices in the network using the antenna 144. For example, the antenna 144 can be used to communicate using a direct connection (e.g., over a Bluetooth connection, over a direct Wi-Fi connection such as an ad hoc Wi-Fi connection or Direct Wi-Fi connection), and/or an indirect connection (e.g., over a LAN, over a mesh network, etc.).
As illustrated in
Accordingly, the pump 100 can receive data or operating information from other network connected pool pad equipment, and can send that data or operating information to a server or the remote user device 380. Similarly, the remote user device 380 can send instructions to pump 100 and the pump 100 can transmit those instructions to any of the network connected pool pad equipment. Further, network connected external sensing devices such as flow meters, flow switches, temperature sensors, TDS sensors, pH sensors, etc. can communicate sensed data to the pump 100 via wired or wireless communication, and the pump 100 can communicate the sensed data to a server or the remote user device 380. Accordingly, the pump 100 can effectively act as a control hub and a communication hub for the pool pad devices and any related external sensors.
For example, in some forms, the pump 100 can include logic to control, through the onboard controller 134 or the remote device 380, a pool lighting assembly. The pump 100 can transmit instructions to the lighting assembly to dictate when and how the lighting assembly is illuminated, such as days of the week, times of day, duration of illumination, pattern of designs, colors, or animation types. Similarly, the pump 100 can include logic to control a salt chlorine generator, chlorinator, or other chemical dispensing system such as the days of the week and times of day the salt chlorine generator is activated.
Next, the pump 100 can receive sensor data transmitted from a water quality monitor, such as a water quality monitor that can measure temperature, oxidation reduction potential (ORP), and pH. Further, the pump 100 can use the received ORP, pH, and temperature values sensed by the water quality monitor to change the operating functions of the pump 100 itself or the operation of other pool pad equipment. For example, in response to the received water quality monitor sensor data, the pump 100 can change the flow rate, pump speed, and timing, such as time of day, frequency, and length of time, that the pump 100 is operated. Further, the pump 100 can instruct a device to inject muriatic acid into the pool. The pump 100 can also transmit the received water quality monitor sensor data to a server or the remote device 380 for aggregation and analysis.
In another example, the pump 100 can include logic to control water features, fountains, or valves within the pool circulation system. Accordingly, the pump 100 can transmit instructions to the water features, fountains or valves to turn on or off, open or close, dispense water in a plurality of designs, and/or follow a particular schedule of operation during particular days or times. In some instances, the pump 100 can transmit instructions to operate certain water features, fountains or valves in coordination with the operation schedule of the pump 100.
In another example, the pump 100 can include logic to control a heater for the pool. Accordingly, the pump 100 can transmit instructions to the heater to heat the water to a particular set point, turn on or off, or run on a particular schedule of days and times. The pump 100 can also transmit instructions to control the operation of the heater in response to temperature sensed by the pump 100 itself, a temperature sensed by the heater, or a temperature sensed by another network connected external temperature sensor such as the temperature sensor provided with the water quality monitor discussed above. The pump 100 can also control the flow dependency of any or all pool pad equipment and external sensor devices, thus deactivating or activating the pool pad equipment, or external sensor devices based on whether the pump 100 is currently pumping water through the circulation system.
All of the aforementioned functions and instructions transmitted by the pump 100 can be initiated by way of user input at the onboard controller 134 or the remote device 380. Further, any or all of the physical buttons 300, the touchscreen display 316, the automation device 176, the mid-level automation device 180, and the remote user device(s) 380 may enable a user to manage virtual computing resources allocated to an account setup by the user and be configured to implement an IoT platform for the pump 100.
As illustrated in
The buttons 300 can simplify the options and provide basic functionality such as power on/off, and can provide one or more pre-programmed functions for the pump 100. For example, a quick clean button 304 can be provided which runs the pump 100 at a user configurable speed for a user configurable amount of time, such as 1 hour. High and low speed buttons can be provided to allow for selection between continuous operation at a preprogrammed or manually selected high or low speed until another selection is made, such as power off with a power on/off button 308. The on-board physical buttons 300 can also assist with connecting the pump 100 to other devices in a network to provide additional user interface control options. For example, the physical buttons 300 can include a network connection button 312, which can be pressed during a network connection process by which the pump 100 is wirelessly connected to a Wi-Fi network, a peer-to-peer network, cellular network, or other wireless network as described above.
One or more of the buttons 300 can include one or more LED lights, which can be provided in a variety of colors. In some forms, the LEDs illuminate in different colors and patterns to indicate conditions of the pump 100. To name a few non-limiting examples, each button 300 can have an associated green, blue, orange, and red LED, and each of the LEDs can illuminate as a solid continuous light, a pulsing light, or a blinking light in predetermined orders or combinations. Accordingly, the combination of color and illumination pattern can be associated with a particular condition of the pump 100. For example, various light and pattern combinations illuminated underneath the network connect button 312 can include: a green pulsing light indicating that Wi-Fi is connecting; a solid continuous green light indicating that Wi-Fi has successfully connected; a blinking blue light indicating that a Bluetooth device is pairing; a solid continuous blue light indicating that the Bluetooth device has successfully paired; a pulsing orange light indicating that wireless provisioning is needed; and a blinking orange light indicating that the software is updating.
Another example includes the power on/off button 308 illuminating as follows: a solid continuous green light indicating that the pump 100 is running; a blinking green light indicating that the pump 100 is priming; a pulsing green light indicating that the pump 100 is in a thermal mode; a solid continuous red light indicating that the pump 100 is disabled; a red blinking light indicating one or more alarms are active; and a simultaneous and continuous orange and green light indicating a warning.

In some forms, the touchscreen display 316 can be sized between about 3 inches and about 8 inches. Upon powering on the pump 100, the touchscreen display 316 can display, and provide access to, a virtual environment stored in the software of the main circuit board 228. In some embodiments, the touchscreen display 316 can be selectively removable and mountable in a remote location, such as a nearby wall, and coupled to the main circuit board 228 by a cable to deliver power and provide communication. When the touchscreen display 316 is mounted in a remote location, a cover plate can be attached to enclose the space in the housing of the pump 100 created by removing the touchscreen display 316.
As shown in
These values can be displayed in a variety of forms as set by the user. For example, the pump speed can be displayed in RPM or as a percentage of a maximum pump speed; the estimated flow value can be displayed in gallons per minute (GPM), liters per minute (LPM) or a percentage of the maximum pump flow; the estimated power consumption value can be displayed in watts or horsepower; and the estimated pressure value and/or system head pressure can be displayed in pressure per square inch (PSI) or kilopascals (kPa). The example value types are understood to be non-limiting, and that any of the aforementioned values can be displayed in the form of any unit or measurement appropriate to convey the value to a person of skill in the art. The touchscreen display 316 can also be configured such that the screen is orientated in either landscape or portrait format to accommodate the user's preference and the position of the pump 100 on the pool pad.
In some forms, the onboard dashboard screen 320 provides a plurality of user selectable modules to navigate throughout the virtual environment. For example, the onboard dashboard screen 320 can include a running programs module 330, a home button module 334, an alerts module 338, a favorite programs module 342, a pump schedule module 346, and a device settings module 350. In some forms, any or all of the modules 330, 334, 338, 342, 346, and 350 can be accessible/displayed/selectable by the user from any point of navigation through the virtual environment.
In some forms, each of the pump operation programs 322 are displayed along with a user-selected title such as “Morning Clean”, the days of the week that the program runs, the time of day the program runs, the pump speed or flow rate at which the pump 100 operates, and a short description of any auxiliary device 174 electrically connected to the pump relay terminal blocks 196 that is scheduled to be activated during activation of any particular operation program 322. Accordingly, various auxiliary devices 174 can be associated with various pump schedules, and in some forms, two or more auxiliary devices 174 can be configured to be active at the same time. From the list of pump operation programs 322, each of which may be immediately visible, or the user can scroll on the page if the number of operation programs 322 exceeds the space on the touchscreen display 316, the user can turn on or off any of the operation programs 322 by selecting an ON/OFF button 354 associated with any particular operation program 322. The ON/OFF button 354 can be presented as a green circle with a play button symbol when the operation program 322 is not active, indicating that the user can press the green circle to activate the operation program 322. The ON/OFF button 34 can also be presented as a red circle with a pause symbol when the operation program 322 is active, indicating that the user can press the red circle to deactivate the operation program 322.
The user may also navigate within the virtual environment to edit each individual operation program 322 by clicking on, for example, an “edit” button 358. If no operation programs 322 have yet been set-up by the user, the user may also select an option that navigates to another setup screen to input a new program. After selecting the “edit” button 358, or when setting up a new operation program 322, the user can configure any of the individual parameters of that existing or new operation program 322. For example, the user can change the nickname, the days of the week for activation, the pump speed or flow rate, the time of day for activation, a manual, schedule, or timer mode (described further below), and which, if any auxiliary devices 174 will be activated for the given operation program 322. Once the desired programs have been created, the user can navigate back to the onboard dashboard screen 320 using the home button module 334.
Referring back to the onboard dashboard screen 320, the user can select the device settings module 350 to configure various aspects of the controller 134 itself, view the network connectivity status of the pump 100, or view other information related to the pump 100. For example, after selecting the device settings module 350, the user can be offered options to: view general information about the pump 100 such as a nickname, address, or software information; select a screen orientation preference for how the virtual environment is displayed on the touchscreen display 316; view Wi-Fi network connectivity information and signal strength; configure the brightness of the touchscreen display 316; configure dimming and timeout settings for the touchscreen display 316; view and edit information relating to auxiliary device 174 that is electrically connected to the pump relay terminal blocks 196; view and edit pump priming parameters; view and edit limits for the operation of the pump 100 based on speed, flow, pressure, and the like; view and edit a thermal mode to protect the pump from freezing; view and edit address information associated with the automation device 176 if connected; configure the ramp-up speed rate of the pump 100 (e.g. fast, medium, slow); and/or select any language preferences for the touchscreen display 316.
Examples of such designation options for the auxiliary devices 174 includes designating the auxiliary devices 174 as one of a lighting assembly, a salt chlorine generator, a water quality monitor, a booster pump, a single speed pump, a chlorinator, a pool vacuum, a water feature, a fountain, a heater or a placeholder “other”, which can be any auxiliary device 174 that is electrically compatible with the relay terminal block 196 to which it is connected. The options of auxiliary devices 174 can be displayed and selected via the onboard dashboard screen 320. The user can also designate a nickname to any of the auxiliary devices 174 for easy identification during system programming. Further, the user can designate whether any given auxiliary device 174 is speed or flow dependent, and, thus, should not be powered when no volumetric water flow is being delivered through the pump 100 or the pump 100 is not running. In some forms, a minimum pump speed or flow rate can be assigned to the activation of a particular auxiliary device 174 such that the auxiliary device 174 can only be activated when the pump 100 is operating above a certain speed or flow rate. In some instances, the auxiliary device 174 will be deactivated when no water flow is being delivered or the flow rate decreases below a threshold flow value.
With respect to the alerts module 338, a variety of alerts can be provided to the user in visual, audio, or other forms including, but not limited to, an alert corresponding to the thermal mode being active (to prevent pump freeze), an overheat condition associated with any of the components of the pump 100, an overcurrent, overvoltage, or undervoltage condition associated with any of the electrical components of the pump 100 such as the drive 130, a pump speed limit, a pump pressure limit, a flow limit, a priming failure, a weak Wi-Fi connection, the pump 100 being offline, a communication error, or an internal error associated with the power supply and/or a power factor correction circuit in electrical communication with the power supply of the pump 100. It is to be understood that along with the alerts module 338 of the touchscreen display 316, any of the aforementioned alerts can also be displayed in various ways by any of: the physical buttons 300 located on the pump 100 itself; the touchscreen display 316; the automation device 176; the mid-level automation device 180; the remote user device 380; or via any notification method selected by the user such as email or text notifications to a mobile phone. Any of the thresholds associated with the alerts for the pump 100 can be programmed into the software of the onboard controller 134. Alternatively, some of the thresholds associated with alerts can be based on hardware limitations associated with the pump 100.
As mentioned above, the onboard controller 134 can wirelessly (or in a wired configuration) be connected to an IOT device within a network, including the remote user device 380 (see
To establish a wireless connection between the remote user device 380 and the pump 100, the user can select the device adding module 404. Once the device adding module 404 is selected, the remote user device 380 will navigate to a screen where the user can select a virtual representation of the pump 100. The user can select the virtual representation of the pump and then press the network connection button 312 on the pump 100 to begin pairing the pump 100 with the remote user device 380. LED lights below the network connection button 312 will indicate to the user the status of pairing as mentioned above. Based on the color and pattern of the network connection button 312, the user can determine the success of the pairing function and select a confirmation button on the remote user device 380 accordingly. Thereafter, the remote user device 380 will be paired via Bluetooth to the controller 134 of the pump 100. Next, as shown in
Upon selecting a given operation program 322, the remote user device 380 will navigate to the display screen shown in
It should be noted that any of these configurable pump settings, or others such language preference, clock configuration, location settings, can be stored at the remote user device 380, at a server, or in the memory unit of the main circuit board 228. Accordingly, if any of the remote user device 380, the server, or the main circuit board 228 experience failure, one of the other still functioning resources can push the configured pump settings to the failed resource upon reboot. For example, if the main circuit board 228 is damaged, crashes, or experiences an unexpected power cycle, the pump settings stored on the remote user device 380 or the server can be downloaded to the main circuit board 228 of the onboard controller 134 once the main circuit board 228 is fixed, replaced, or returned to normal operation.
As shown in
Referring next to the specific functions of the pump 100, the variable speed pump 100 can provide a number of customizable and user controlled functions. For example, any of the operation programs 322 can be configured by the user to run the motor 110 at a percentage of the maximum pump speed setting or at an absolute value of RPM. The pump 100 can also control the speed of the motor 110 based on an estimated flow rate value using one or both of the drive 130 and the onboard controller 134. Accordingly, the pump 100 will maintain a constant flow rate value as set by the user as an absolute value or a percentage of the maximum flow rate setting. For example, the pump 100 can be programmed to deliver between about 20 GPM to about 140 GPM of volumetric water flow. Manual, timer, and schedule modes can be selected for each operation program 322 and eight or more customizable programs can be saved and stored. If a manual mode is selected, the pump with run at the designated speed/flow only when the user manually initiates the operation program 322 and will run indefinitely until the user turns off the operation program 322. If a timer mode is selected, the operation program 322 will only start when the user manually initiates it and will operate the pump 100 at the specific parameters for a set period of time. If the schedule mode is selected, the user has the most customizable control and the operation program 322 will start and end at the set times/day and will operate the pump 100 at the set flow and/or speeds set by the user. If configured, the user can also designate which of the relay terminal blocks 196 will be active while any of the operation programs 322 are running and provide power whenever the pump 100 is operating. In this way, the electrically connected auxiliary devices 174 can operate at the same time as the pump 100.
As briefly mentioned above, the pump 100 can include a user configurable priming function. The priming function runs the pump 100 at a designated speed, usually much higher than normal pump operation, for a specified period of time at the startup of the pump before any of the operations programs 322 are run. Once the pump 100 detects that priming has been achieved (by monitoring power consumption of the drive 130 or through other sensor based methods like a flow sensor) the pump 100 can begin any of the operation programs 322. A delay time can be set between the time that priming is detected to be achieved to the time that the operation programs 322 are initiated. If priming is not achieved within the specified period of time, the pump 100 will power off and an alert will be issued to the user in any of the aforementioned alert methods. In some forms, when priming is enabled, the pump 100 also monitors for a dry run condition during pump operation. Thus, if dry run is detected, for example when a certain power consumption value of the drive 130 is detected for a certain period of time, the pump will be powered off and an alert will be issued. In some forms, the pump 100 will check for dry run regardless of whether the priming function is enabled.
In some forms, the pump 100 is a slave device to the communicatively connected automation device 176. In some forms, the pump is a slave device to the communicatively connected mid-level automation device 180. In this way, the automation device 176 or the mid-level automation device 180 can initiate any of the operation programs 322 as described above. It should be noted that because multiple remote user devices 380 can provide the same functions and allow all of the same configurability as the others, the remote user device 380 can, in some embodiments, also be accessed by a pool service professional to manage, monitor, and control the pump 100 of a customer.
As mentioned above, the pump 100, by way of the pump drive 130, can calculate estimations of various pump parameters, such as pump power consumption value aggregated or averaged over a period of time, the current system pressure value, pump speed, the total dynamic head value, the pump flow rate value, and a total gallons pumped value. These parameters can be measured and estimated for multiple discrete time periods, aggregated for multiple time periods or averaged over multiple time periods, and the raw data, or processed data, can be aggregated or averaged and stored in one or more of the virtual platforms such as on the onboard controller 134, the server, or the remote user device 380. Further, the user can enter various parametric aspects of the pool or aquatic application into the onboard controller 134, or the remote user device 380, such as a pool volume estimate, or municipal information such as energy costs. Accordingly, pump data, such as kilowatt-hours consumed by the pump 100 over time, gallons pumped over time, and turnover rate for a particular pool can be determined, stored, and/or manipulated in a virtual platform. Turnover rate is the number of times the full volume of the pool will be circulated through by pump 100 in a given time period. For example, if the pool volume is 20,000 gallons, and the pump 100 is operated for 2 hours each day at 100 GPM, the turnover rate is 0.6 turnovers per day or 4.2 turnovers per week (7 days). The turnover rate will be higher with a higher flow rate value, a longer run time per day, a higher frequency such as twice a day, and a lower pool volume, and vice versa. Other parameters that can be measured, estimated, tracked, or stored by the onboard controller 134, remote user device 380, or related virtual platform, include the time that the pump 100 is actively pumping fluid, and the time that the time that the pump 100, or the onboard controller 134, is generally on/initiated.
The pool pump 100 is configured to pump water within a pool or spa circulation system, and in some embodiments, external sensors and devices can be used within the pool circulation system and can communicate with the pump 100 by way of any of the wired or wireless communication methods mentioned above with the main circuit board 228 of the onboard controller 134. For example, one or more auxiliary pressure sensors can be positioned in various locations along the pool circulation system to measure pressure values, communicate the pressure values with the onboard controller 134, and ultimately help supplement or provide more accurate estimations or assessments of various pool parameters, such as the total dynamic head value. A number of useful auxiliary pressure sensor locations can include positioning the auxiliary pressure sensor on a suction side of the pump 100, positioning the auxiliary pressure sensor on the discharge side of the pump 100, or positioning the pressure sensor on a downstream side of a filter assembly, the filter assembly being downstream from, and on the pressure side of, the pump 100. Further, one or more auxiliary flow meters can be provided to measure flow rates at various points in the pump circulation system, and the auxiliary flow meters can communicate measured flow rate values to the onboard controller 134. The measured flow rate values can help provide more accurate estimations or assessments of various pool parameters such as total gallons of water pumped averaged or aggregated over a period of time, or a current pool turnover rate averaged or aggregated over a period of time.
Because each pool circulation system has unique qualities, such as unique frictional losses, which are determined in part by static features such as the length and diameter of the circulation system plumbing, the type of filter system used, or the type of backwash valve used and in part by dynamic features that can fluctuate based on the status of the pool circulation system such as pool filter loading characteristics, heater bypass, water feature activation, and other pool circulation system valve actuation, it is useful to collect and analyze data corresponding to the pool circulation system friction curve (system head pressure versus flow rate). In some embodiments, the system friction curve can be generated manually through user activation of the pump 100 at two or more pump speeds, and the onboard control 134 can estimate the total dynamic head values at each pump speed, or, alternatively, the system friction curve generation can be performed automatically or as a preprogrammed algorithm initiated automatically or through a one-click operation by the user. Data collected from auxiliary pressure sensors and auxiliary flow sensors can also be combined with the data collected/generated by the drive 130 (e.g., power consumption value over a period of time, the current system pressure value, the total dynamic head value, the pump flow rate value, and total gallons pumped value) in order to provide higher-accuracy pump performance data and/or higher accuracy system friction curves.
Using the pump data aggregated at one or more of the onboard controller 134, the server, or the remote user device 380, the variable speed pumping system including the pump 100, e.g., the pool circulation system, can be placed into one or more categories. For example, depending on the generated system friction curve X1, Y1, Z1, X2, Y2, or Z2, the pool circulation system can be categorized into a “high load system”, a “medium load system”, or a “low load system”. For instance, generated friction curves that fall within a certain percentile range, e.g., 0-20% of the X1 or X2 curves can be determined to be a “high load system”, generated friction curves that fall within a certain percentile range, e.g., 0-20% of the Y1 or Y2 curves can be determined to be a “medium load system”, and generated friction curves that fall within a certain percentile range, e.g., 0-20% of the Z1 or Z2 curves can be determined to be a “low load system”.
The categories and curves presented herein are non-limiting and merely exemplary in nature. More or fewer categories for the pool circulation system can be provided for more granular categorizations and larger or smaller percentile ranges can be used to create more broadly encompassing or narrowly tailored categories. Additionally, multiple system friction curves can be generated for a single pool circulation system when the pool circulation system is operating under different frictional loss conditions. For example, a first system friction curve can be generated when one or more water features are activated, a second system friction curve can be generated when a pool heater is active, and a third system friction curve can be generated when the heater is bypassed and the water features are inactive. Also, the system friction curves can be updated over time to consider changes in resistance over time, such as increases in filter load. Thus, X1, Y1, Z1 and X2, Y2, Z2 can represent system friction curves developed at different times and valve conditions for the same pool circulation system rather than the pump 100 as it is used in different pool circulation systems.
Once the system friction curve or curves have been developed and/or the total gallons pumped value and an estimated current pool turnover rate have been calculated, the onboard controller 134, server, and/or the remote user device 380 can provide a variety of recommendations to the pool owner. In some embodiments, based on the total gallons pumped value over a period of time, a recommendation can be provided to increase or decrease the pool turnover rate depending on the pool size input by the user or a pool use factor input by the user or determined by way of a bather load sensing device. For example, based on the pool size input by the user, pool use factor, and the calculated total gallons pumped value over a period of time, it can be determined whether the user is turning over the pool more or less frequently than is required for adequate pool sanitation. The pool use factor input by the user can be provided in the form of a broad category input, such as “high”, “medium”, or “low”, the pool use factor can be provided in the form of a numerical value, such as on a scale of 1-10, or another quantification. The bather load, e.g., the total number of bathers within the pool can be detected by way of a visual sensor or manually input by the user such as the number of bathers and the time in the pool. Accordingly, the onboard controller 134, server, and/or the remote user device 380 can provide a recommended, updated pump operation schedule(s) along with motor speed and flow rate recommendations to the user that will provide adequate pool water filtration while reducing the energy consumed by the pump 100 by way of an updated turnover rate. For example, the updated pump operation schedule can include more or less hours of pump operation time, different days of pump operation, higher or lower pump speed, and/or higher or lower pump flow rate values in order to implement the appropriate turnover rate and reduce pump operating costs. An estimated reduction in operating costs can be calculated based on an estimated, updated power consumption value determined for the updated pump operation schedule. In some forms, a recommended, updated priming speed and maximum priming run time can be provided.
Alternatively, or in addition, based on the system friction curve or curves generated, and, consequently, a categorization as high load, medium load, or low load system, the measured or estimated pool turnover rate, along with the municipal energy costs input by the user, a recommended, updated pump schedule(s) can be provided. For example, the onboard controller 134, server, and/or the remote user device 380 can provide a recommended, updated pump operation schedule(s) along with motor speed and flow rate value recommendations to the user that will provide adequate pool water filtration while reducing the energy consumed by the pump 100 based on the system friction curve. For example, the updated pump operation schedule can include more or less hours of pump operation time, different days of pump operation, higher or lower pump speed, and/or higher or lower pump flow rates in order to reduce pump operating costs and optimize pump performance. In some forms, the updated pump schedule will include an increase or decrease in pump speed or flow rate value in order to achieve a target turnover rate value or target energy cost value in light of the estimated system frictional losses. In some forms, the updated pump schedule will include an increase in pump operation time or a decrease in pump operation time in order to achieve a target turnover rate value or target energy cost value in light of the estimated system frictional losses. In some forms, the updated pump schedule will include changes to the pump speed or flow rate value and the pump operation time in order to achieve a target turnover rate value or target energy cost value in light of system frictional losses.
For example, if the pool circulation system is determined to be a high load system, e.g., X1, X2 due to accumulated filter loading over time, in order to keep energy costs down and achieve a target energy cost value, the updated pump schedule can include an updated pump speed which is lower, but an updated pump operation time which is increased in order to maintain an acceptable target turnover rate value. This is due to the fact that pump operation energy costs decrease by a polynomial degree, such as by an order of three, in response to a decrease in pump speed, while the pump flow rate decreases proportionally to a decrease in pump speed. In contrast, if the pool circulation system is determined to be a low load system, the updated pump schedule can include an updated pump speed which is higher in order to optimize pump efficiency. In addition, for the low load system, the updated pump schedule can include an updated pump operation time which is decreased, to lower the energy costs and achieve a target energy cost value while keeping the turnover rate value at an acceptable level.
An estimated reduction in operating costs can be calculated based on an estimated, updated power consumption value determined for the updated pump operation schedule. In some forms, a recommended, updated priming speed and maximum priming run time can be provided. Further, recommendations can be provided as to the type of operation and times of operation of other pool pad equipment, such as valves in the pool circulation system, heaters, sanitation devices, water quality monitors, chlorinators, booter pumps, or other pool components. For example, if the pool circulation system is determined to be a high load system, a recommendation for more frequent heater bypass when the heater is not on can be provided. In addition, the onboard controller 134, server, and/or the remote user device 380 can display a cost comparison between the current pump operation schedule and the updated pump schedule(s). For example, a monthly or daily estimated energy cost comparison can be made between the current pump schedule and the updated pump schedule.
In some embodiments, based on the system friction curve, different pool equipment can be recommended for the pool circulation system that has fewer frictional losses, such as recommendations for a higher efficiency filtration system, heaters, sanitation devices, water quality monitors, chlorinators, booter pumps, valves, lower restriction backwash valves, etc. Similarly, different pool equipment can be recommended based on the estimated current pool turnover rate, such as different capacity filtration systems. Even further, the payback period associated with the purchase of new pool equipment as it relates to the cost savings resulting from using the purchased pool equipment in the pool circulation system can be displayed to the user on the onboard controller 134, server, and/or the remote user device 380. Accordingly, users can make informed pool equipment purchases that will optimize their pool circulation system and provide energy cost savings over time.
In some forms, the user can be notified through alerts, charts, graphs, visual displays and/or other user notification means on one or both of the remote user device 380 or the onboard controller 134. The user notification means can provide a comparison between the current pump operation schedule and one or more recommended, updated pump operation schedules. For example, the user notification means can present the cost savings per month provided by one or more recommended, updated pump operation schedules compared to the current pump operation schedule. Accordingly, the user can decide whether to change the current pump operation schedule to be correlated with one or more of the updated pump operation schedule recommendations, such as modifying the pump operation time, days of pump operation, higher or lower pump speed, and higher or lower pump flow rates. The pump operation schedule can be updated manually, semi-manually, or the updated pump operation schedule can be packaged together, presented as a single-click option for the user, and all of the pump operation parameters can be changed in one-click.
In some forms, the onboard controller 134, server, and/or the remote user device 380 will automatically optimize and update one or more of a pump motor speed, a pump flow rate value, pump operation schedule, a pool circulation system valve orientation, a pool heating schedule, a pool sanitization schedule and a filter backwash or filter cleaning schedule based on the system friction curve or the total gallons pumped value and current pool turnover rate, without the user having to interact with the onboard controller 134, server, and/or the remote user device 380. Accordingly, the current settings of the pump 100 will be overridden and updated. As mentioned above, because pool service professionals can monitor, control, and manage operation of the pump 100 remotely, any or all of the recommended changes above can be implemented remotely by the pool service professional in response to any or all of the recommendations provided.
Additionally, because the total gallons pumped value throughout the life of the pump 100 can be aggregated at the onboard controller 134, server, and/or the remote user device 380, periodic maintenance for the pump 100 or other pool pad equipment can be recommended based on various timeline milestones. For example, replacement of seals, filters, or other parts can be recommended after a certain number of gallons have been pumped by the pump 100, or after a particular amount of time has passed. The service recommendations can be provided by way of a notification to the user through alerts, messages, audio and/or visual displays and/or other user notification means on one or both of the remote user device 380 or the onboard controller 134.
Further, based on the current turnover rate of the pool circulation system, the pump 100 can be categorized as high-use, standard-use, or low-use. Indeed, larger pools or pools with a high pool use factor (mentioned above) will require higher pump speeds, higher flow rates, and longer or more frequent pump operation times than smaller pools with a low use factor. Accordingly, predetermined recommendations regarding a periodic maintenance schedule, what pool pad equipment to use/purchase, service types and schedules, and equipment replacement schedules can be provided in accordance with the pump use category or system friction curve category. For example, if the pump 100 is categorized as high-use or used in a high load system, the user can receive more frequent or different pump service notifications, such as filter cleaning or filter backwash, after a period of time or after a certain number of gallons pumped than if the pump 100 if categorized as standard-use or light-use or used in medium load or low load systems.
The user can also be notified to replace parts of the pump 100 that experience periodic wear such as mechanical seals and o-rings based on any of the pump data mentioned above, such as the passage of a period of time or after a total gallons pumped value. Another example is that the user can be instructed to backwash or clean a filter assembly in the pool circulation system if the measured or estimated pressure values, or an applicable portion of discrete generated system friction curve values, are too high for a period of time. Pump data analytics such as regression analysis can be performed at the onboard controller 134, the server, the remote user device 380, or at any other equipment that is network connected to the pump 100. Artificial intelligence and machine learning can be applied such that periodic changes in the pump 100 or pool circulation system can be controlled and predicted. In some embodiments, new pool pad products will be recommended based on the total gallons pumped or the time in service of the pump 100 such as a new filter assembly, a new pump 100 when it reaches end of life, or a new heater, chlorinator, sanitizer, etc. The recommendations provided for new pool pad products can also depend on the pump categorization as a severe duty, standard duty, or light duty system or use in a pool circulation system categorized as low load, medium load, or high load. Further, any or all of the controls, notifications, and analyses described herein can also be performed by way of the automation device 176 or mid-level automation device 180.
