Development and application of Zhongyuan new type energy-saving submersible motors

Zhongyuan new type energy-saving submersible motors are developed for solving such problems as large energy consumption and high lifting costs during the production of the electric pump wells. The technical basis, technical line and key points of the new motor are introduced, and the result of the optimization and the energy-saving effect are analyzed. Compared with that of the Zhongyuan Tongtu motor, The average working current of this new kind of motor could be reduced by 45.2%, the average power and power factor could be improved respectively by 4.53% and 3.72%, and the enegy dissipation of the cable could be lowered by 68.3%. Application shows that the new type of electric motor has such advantages as lowering the energy consumption of the pumping system, extending the service life of the ESP set, reducing the operation and maintenance cost and increasing the oil production of the ESP wells.
