【Abstract】 A new smart energy-saving controller for pumping units is designed. It can judge the under-well liquid supply ability according to detecting the motor power factor. The controller can prolong the exploitation life of low-output wells, and reduce the wear and tear of the machine parts and the electric cost. It has better ability of anti-jamming. Practice shows that the controller runs smoothly and reliably.更多还原
