 Direct-drive electric submersible progressive cavity pump is a newly developed advanced oil extraction equipment in recent years and has the following advantages:

. Simplified structure,eliminating the need for structures such as reducers,i mproving reliability;

.The ground requires alow voltage, which can save investment intransformers and other parts of the oil well, and at the same time reduce the cable requirements;

. Large starting torque,the initial starting torque up to 1.8 to 2 times the rated torque, can start with load;

.The system has high efficiency and remarkable energy-saving effect: Compared with the traditional machine-making equipment of traditional asynchronous motors, the electricity consumption can save 30% to 50%;.

.The use of permanent magnet synchronous submersible motor, equipped with special frequency conversion cabinet, has the characteristics of simple operation, high degree of automation and highpower factor;

. It has strong adaptability, is not easy to sand card,and is not easy to produce airlock. It can be applied to oil  and gas with high sand content and high water content in large inclined wells and horizontal wells;

.Small foot print, no noise, no leakage pollution, suitable for use on offshore platforms and urban oilfields, with high safe ty performance.
