Problems solved by technology

[0002] During the oil pumping process in the oil field, the motor configuration needs to be larger to ensure heavy-duty starting. Therefore, there are always large horses and small carts in the oil pumping system, resulting in low power consumption efficiency, large reactive power, and low power factor; In the oil production cycle of pumping a well, the oil volume is relatively large at the beginning, the oil volume gradually decreases, and the motor load also gradually decreases, resulting in a decrease in system efficiency. It needs to do negative work, so it is also necessary to adjust the power output of the motor; in one cycle of pumping, the speed is constant, and there is often a large amount of leakage
At present, there are frequency conversion or other high-efficiency motor applications to solve the energy consumption problem of pumping units, but none of them can completely solve the existing problems
