Product Introduction
PRODUCT INTRODUCTION (WORKING PRINCIPLE, COMPONENT PARTS, OPERATINGMODE
Working Principle
After the pump unit of the ESPCP system is lowered down into the well, the power is transmitted through the power cable to the submersible motor under the well to drive the progressive cavity pump(PCP) and the fliud in the well is then raised up onto the ground with the pressure boost of PCP.

Operation Mode
During operation, the electricity is transmitted via the submersible cable from the servo control system on the ground to the purpose-designed permanet magnetic synchronous motor in the down-hole for stepless speed regulation so that the motor can run at a low soeed but a high torgue output, driving PCP to extract oil through the protector and thr shaft coupler.
