The switch 178 electrically communicates with the microcontroller 94 of the digital display unit 18, via the connector 108, the connector 102 and the printed circuit board 90 of the digital display unit 18, so that the microcontroller 94 of the digital display unit 16 recognizes the type of sensor from which it is (or at least should be) receiving digital information, namely a pressure sensor, such as the digital pressure sensor 56. Based on this recognition, the microcontroller 94 accordingly processes the digital information and outputs relevant digital output specific to that sensor type on one or more of the displays 96a, 96b, 96c and 96d of the digital display unit 18. In an exemplary embodiment, the microcontroller 94 of the digital display unit 18 may output, for example, a pressure value at the casing 64 on one or both of the displays 96a and 96b of the digital display unit 18.
Before, during and/or after the transmission of digital information to the digital display unit 18, the batteries 76a and 76b of the digital display unit 18 supply electrical power to the electrical components on the printed circuit board 90 of the digital display unit 18, including the microcontroller 94. The batteries 76a and 76b of the digital display unit 18 supply electrical power to such components via the respective holders 70a and 70b, the cable assembly 114, the connector 112, the connector 98, and the printed circuit board 90 of the digital display unit 18. Additionally, before, during and/or after the transmission of digital information to the digital display unit 18, the batteries 76a and 76b of the digital display unit 18 supply electrical power to the digital pressure sensor 56 via the respective holders 70a and 70b, the cable assembly 114, the connector 112, the connector 98, the printed circuit board 90, the connector 100, the cable assembly 104, and the connector 78 of the digital display unit 18, as well as a connector that is equivalent to the connector 106, and the cable assembly 60.
In an exemplary embodiment, to monitor the respective stroke counts (and thus flow rate indications) of the pumps 50 and 52, the digital stroke counters 40 and 42 sense the respective strokes of the pumps 50 and 52, and then transmit digital readings or information corresponding to the sensed strokes to the digital display unit 20. The digital stroke counter 40 transmits the digital information to the digital display unit 20 via the cable assemblies 44 and 46. The digital stroke counter 42 transmits the digital information to the digital display unit 20 via the cable assemblies 48 and 46. At the digital display unit 20, the digital information from the digital stroke counters 40 and 42 is transmitted to the microcontroller 94 of the digital display unit 20 via a connector that is equivalent to the connector 106, and the connector assembly 78, the cable assembly 104, the connector 105, the connector 100, and the printed circuit board 90 of the digital display unit 20. The switch 178 electrically communicates with the microcontroller 94 of the digital display unit 20, via the connector 108, the connector 102 and the printed circuit board 90 of the digital display unit 20, so that the microcontroller 94 of the digital display unit 20 recognizes the type of sensor from which it is (or at least should be) receiving digital information, namely a stroke counter, such as the digital stroke counters 40 and 42. Based on this recognition, the microcontroller 94 accordingly processes the digital information and outputs relevant digital output specific to that sensor type on one or more of the displays 96a, 96b, 96c and 96d of the digital display unit 20. In an exemplary embodiment, the microcontroller 94 of the digital display unit 20 may output, for example, a stroke rate such as the strokes per minute of the pump 50 on the display 96a of the digital display unit 20, the total strokes of the pump 50 on the display 96c of the digital display unit 20, a stroke rate such as the strokes per minute of the pump 52 on the display 96b of the digital display unit 20, and the total strokes of the pump 52 on the display 96d of the digital display unit 20.
Before, during and/or after the transmission of digital information to the digital display unit 20, the batteries 76a and 76b of the digital display unit 20 supply electrical power to the electrical components on the printed circuit board 90 of the digital display unit 20, including the microcontroller 94. The batteries 76a and 76b of the digital display unit 20 supply electrical power to such components via the respective holders 70a and 70b, the cable assembly 114, the connector 112, the connector 98, and the printed circuit board 90 of the digital display unit 20. Additionally, before, during and/or after the transmission of digital information to the digital display unit 20, the batteries 76a and 76b of the digital display unit 20 supply electrical power to the digital stroke counters 40 and 42 via the respective holders 70a and 70b, the cable assembly 114, the connector 112, the connector 98, the printed circuit board 90, the connector 100, the cable assembly 104, and the connector 78 of the digital display unit 20, as well as a connector that is equivalent to the connector 106, the cable assembly 46, and the respective cable assemblies 44 and 48.
As indicated above, each of the digital display units 14, 16, 18 and 20 includes a respective combination of the connector assembly 78, the cable assembly 104, and the connector 105; thus, any one of the respective combinations can receive and transmit digital information to the corresponding printed circuit board 90 from the digital hydraulic choke position sensors 30 and 32, the digital stroke counters 40 and 42, the digital pressure sensor 54, or the digital pressure sensor 56. However, the manner in which the corresponding microcontroller 94 processes the received digital information and displays relevant output depends upon which of the switches 110, 154 and 178 is in electrical communication with the microcontroller 94. Additionally, any one combination of the connector assembly 78, the cable assembly 104, and the connector 105 can be used to supply electrical power from the corresponding batteries 76a and 76b to the digital hydraulic choke position sensors 30 and 32, the digital stroke counters 40 and 42, the digital pressure sensor 54, or the digital pressure sensor 56.
In view of the foregoing, in an exemplary embodiment, the use of the digital display units 14, 16, 18 and 20 provides better monitoring accuracy and acuity, and higher incremental resolution of the values of different operation parameters, when compared to the use of analog gauges for the same operation parameters.
In view of the foregoing, in an exemplary embodiment, the commonality in components between the digital display units 14, 16, 18 and 20 facilitates the maintenance of the digital display units, reduces manufacturing and maintenance costs, and increases the usefulness of spare parts because the spare parts can be used on different ones of the digital display units 14, 16, 18 and 20. In several exemplary embodiments, all of the above-described components in each of the digital display units 14, 16, 18 and 20 may be common, or identical, with the exception of some of the parts in the overlay assemblies 122, 142 and 166; such uncommon or different parts may include the switches 110, 154 and 178, and the graphic overlays 126, 144 and 128. The uniformity of the digital display units 14, 16, 18 and 20 reduces costs because parts can be purchased in large quantities, and reduces the number of components a service call technician needs to have available when making remote service calls.
In view of the foregoing, in an exemplary embodiment, any one of the digital display units 14, 16, 18 and 20 may be easily interchanged with any other of the digital display units 14, 16, 18 and 20 by just interchanging the respective overlay assemblies 66.
In view of the foregoing, in an exemplary embodiment, as noted above, the digital display unit 14 is operable with either hydraulic chokes or electric chokes.
In view of the foregoing, in an exemplary embodiment, the ability of each of the digital display units 14, 16, 18 or 20 to supply electrical power to the sensor(s) with which it is in electrical communication (the sensors 30 and 32, the sensor 54, the sensor 56, or the sensors or counters 40 and 42) eliminates the susceptibility of the choke control panel 10 to power losses from another source, such as a drilling rig that is part of the system 24. In other words, the choke control panel 10 may be operated without being dependent upon the supply of electrical power from the drilling rig. The choke control panel 10 operates independently of other electrical power sources. Additionally, the sensors 30 and 32, the sensor 54, the sensor 56, and the counters 40 and 42 operate with their own respective electrical power sources (i.e., the batteries 76a and 76b of the corresponding digital display unit 14, 16, 18 and 20), independently of the other electrical powers sources in the choke control panel 10.
In an exemplary embodiment, as illustrated in
A digital position sensor 208 extends within the longitudinally-extending passage 204 defined by the housing 194. In an exemplary embodiment, the digital position sensor 208 is, includes, or is part of, a linear potentiometer. In an exemplary embodiment, the digital position sensor 208 is, includes, or is part of, an Omega® LP803-02 linear potentiometer. In an exemplary embodiment, the digital position sensor 208 includes a tubular enclosure 208a and a rod 208b extending therein. The rod 208b is movable relative to the tubular enclosure 208a. Respective portions of the tubular enclosure 208a and the rod 208b extend through a compression spring 210.
An actuator button 212 is connected to the distal end of the rod 208b and includes an external shoulder 212a. In an exemplary embodiment, the actuator button 212 is connected to the distal end portion of the rod 208b via a threaded engagement with an external threaded connection 208c at the distal end portion of the rod 208b. The compression spring 210 extends between the external shoulder 212a and a frusto-conical transition internal surface 194e of the housing 194, which internal surface extends between the portions 204a and 204b of the passage 204. As shown in

The base 236 includes an axial end surface 236a, in which an annular groove 236b is formed. The O-ring 234 is disposed in the annular groove 236b and sealingly engages the flange 228i, thereby sealing the connection between the cover 228 and the base 236. A bore 236c is formed in the axial end surface 236a and through the base 236. An end portion 236d, which opposes the axial end surface 236a, is shaped in the form of a male hammer union nose. Thus, the end portion 236d permits the digital pressure sensor 54 to be operably coupled to the standpipe 62 via a hammer union, which employs the end portion 236d. In several exemplary embodiments, instead of a male hammer union nose, the end portion 236d may have other shapes, features, elements, etc. to connect the digital pressure sensor 54 to another component so that the digital pressure sensor 54 is operably coupled to the standpipe 62; such other shapes, features, elements, etc. include, but are not limited to, an external threaded connection, an internal threaded connection, or any combination thereof.
