The present invention relates to a device for the control and management of one or more electric pumps.
The invention also relates to an electric pump to which such a device can be applied.
Devices for the optionally remote control and management of an electric pump are currently widespread.
These devices are fundamentally important, since they provide the user with data on the operation of the electric pump and allow said user, if necessary, to act thereon.
Moreover, devices for the remote control and management of an electric pump allow the user to have an overview of the operation and to act on the electric pump without having to interact directly therewith.
This is particularly advantageous in situations in which an electric pump is installed in a region that is inaccessible and/or difficult to reach.
These remote control and management devices, which are also provided with a user interface, are substantially of two types:
These known methods have some drawbacks.
Control and management devices connected by means of a physical cable to the electric pump have the drawback of having to be provided with a dedicated cable, which takes up space and can have a length of even several meters.
Furthermore, it is necessary to provide two electrical outlets from the electric pump, one for its power supply and one for connection to the control and management device.
This drawback is increased in the case of immersion electric pumps, in which it is necessary to provide an outlet for connection to the control and management device also in the well/tank where the electric pump is used.
Control and management devices connected to the electric pump by means of a wireless data link instead require the presence of data communication means on the electric pump and complementary data communication means on said devices.
The means and the complementary means are connected for example by means of a Wi-Fi mains.
These devices have the drawback that they cannot be used in all kinds of electric pump.
For example, in immersion electric pumps, a wireless link might not reach the electric pump for example due to the depth of the well/tank, which can be even on the order of hundreds of meters, or due to the thickness and composition of its walls.
The aim of the present invention is to provide a device for the control and management of an electric pump and an electric pump to which it is possible to apply such a device which can improve the background art in one or more of the aspects indicated above.
Within this aim, an object of the invention is to provide a device for the control and management of an electric pump that allows remote interaction with the electric pump without requiring a dedicated cable for connection to the electric pump.
Another object of the invention is to provide a device for the control and management of an electric pump that allows remote control by means of a dedicated smartphone and/or tablet application, even for immersion electric pumps.
A further object of the invention is to provide an electric pump to which it is possible to apply a device capable of achieving the aim and objects listed above and to overcome the described drawbacks.
Furthermore, an object of the present invention is to overcome the drawbacks of the background art in a manner that is alternative to any existing solutions.
Another object of the invention is to provide a device for the control and management of an electric pump and an electric pump to which such a device is applicable which are highly reliable, relatively easy to provide and at competitive costs.
This aim, as well as these and other objects which will become better apparent hereinafter, are achieved by a device for the control and management of at least one electric pump, comprising:
said device being characterized in that it comprises PLC data link means.
Furthermore, this aim and these objects are achieved by an electric pump comprising an actuation and power supply unit, characterized in that it comprises complementary PLC data link means connected to said actuation and power supply unit of said electric pump, said complementary PLC data link means being connectable to said device.
Further characteristics and advantages of the invention will become better apparent from the description of a preferred but not exclusive embodiment of the device for the control and management of an electric pump and of the electric pump with such a device, according to the invention, illustrated by way of non-limiting example in the accompanying drawings, wherein:
With reference to the figures, a device for the control and management of an electric pump according to the invention is designated generally by the reference numeral 10.
The device 10 is applied to an electric pump 11, of a per se known type.
One of the particularities of the invention resides in that the device 10 and the electric pump 11 are connected by means of a power line data link, also known as PLC (Power Line Communication).
The device 10 comprises PLC data link means 12 connected to complementary PLC data link means 13 of the electric pump 11.
The PLC data link allows to utilize the electrical mains that is present, provided that the electric pump 11 and the device 10 are connected to the same single-phase mains L.
The mains L is the electrical mains for the power supply of the electric pump 11 and of the device 10.
The device 10 is connected to the mains L by means of a first connection and electric power supply cable 14.
The electric pump 11 is connected to the mains L by means of a second connection and electric power supply cable 15.
As shown in
With reference to
It should be noted that the characteristic of the PLC link allows remote control without the need to use a dedicated physical connecting cable but by utilizing the existing electrical mains.
The electric pump 11, shown in the figures, is an immersion electric pump.
However, the electric pump 11 can also be a surface electric pump. The complementary PLC data link means 13 are connected electrically in turn to the control and power supply unit of the electric pump 11, not shown in the figures.
The PLC data link means 12 are connected electrically to an actuation element 16 of the device 10.
The actuation element 16 is connected to a local user interface 20 and/or to wireless data link means 17.
The actuation element 16 is for example a microprocessor.
The wireless data link means are for example Wi-Fi link means and are adapted for communication with smartphones and/or tablets, not shown in the figures, for the management of the electric pump 11 by means of a dedicated application.
In this case, the user interface is constituted by the smartphone/tablet and by the dedicated application contained therein.
In this manner it is possible to remotely manage, by means of the application for smartphones/tablets, even electric pumps such as immersion ones that are normally not reached by wireless links.
It should be noted that by means of the device 10 it is possible to control and manage even multiple electric pumps 11, all connected to the same single-phase electrical mains L.
By means of the PLC link between the device 10 and one or more electric pumps 11 it is possible to control and interact with them, even remotely, by utilizing substantially the electrical power supply mains L of the former and of the latter.
In practice it has been found that the invention achieves the intended aim and objects, providing a device for the control and management of an electric pump that allows remote interaction with the electric pump without requiring a dedicated cable for connection to the electric pump.
The invention provides a device for the control and management of an electric pump that allows remote control, by means of a dedicated smartphone and/or tablet application, also for immersion electric pumps.
Finally, the invention provides an electric pump to which a device is applied which is capable of achieving the aim and objects listed above and of overcoming the described drawbacks.
The invention thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims; all the details may furthermore be replaced with other technically equivalent elements.
In practice, the materials used, so long as they are compatible with the specific use, as well as the contingent shapes and dimensions, may be any according to the requirements and the state of the art.
