DEVICE FOR POSITIONING ACTUATOR OF RODLESS OIL PRODUCTION SYSTEM WITH DRIVE FROM ELECTRIC MOTOR Russian patent published in 2024 - IPC F04D13/10 

FIELD: oil, gas and coke-chemical industry.

SUBSTANCE: invention relates to oil production equipment. Plunger pump 2 is used in the system of rodless oil production, which requires reciprocal movement for its operation. This movement is provided by an asynchronous electric motor 4 and drive 3, which converts the rotational movement of motor 4 into a reciprocal one. In order to prevent the plunger from reaching extreme positions and the more use of force therein, in lower support 6 of electric motor 4 there is a modified housing of filter 7 having two threaded holes on the plane of the end face. Extensions 8 of sensor 9 are installed in filter housing 7 at the end, in available threaded holes. Sensors 9 are mounted in extensions 8, fixed with nuts. Sectional rim 10 is installed in the lower part of shaft 5 of electric motor 4. Sensor 9 transmits the signal to the telemetric system module 11, and it, in its turn, transmits the signal to monitoring station 1 located on the surface.

EFFECT: invention can be used for well fluid lifting.
