An Analysis of the Application and Engergy-Saving Effect of TL-Speed Control Clutch in Oil Pump Stations

The speed-control clutch is mechanically speed controling device which enables a running machine to keep on working at variable torque, constant torque and constant power with a tranmission efficiency almost equal to the transmission ratio, and another new way of speed control appeared immediately after the speed-control motor and hydraulic coupling which can boast of quite a few performances such as free speed control within a control range from 100% to 30%.
