【Abstract】 Asynchronous motor in surface oil recovery equipment does not match the pumping operation, which makes the motor work improperly. In this paper, we suggest an adjusting equipment be added to the motor shaft in order to decrease output power fluctuation, and to cut down the peak. Therefore, the active power is reduced. The paper analyzes in detail the working principle and design proposal. Calculation shows that: this method achieve remarkable energy-saving effect by 19.57%.更多还原
