Centrifuge special principle of the inverter is solid-liquid separation by centrifugal force effect, usually by feeding, washing, dehydration, knife, discharge and so on several parts, including feeding, washing, knife, discharge part is controlled by electromagnetic valve, pneumatic valve, centrifugal kettle is a major part of the realization of solid-liquid separation, by a three-phase ac motor through a belt drive. According to the characteristics of the process, the material is mainly a solid-liquid mixture at the beginning stage, and the load is relatively large at the beginning. When a certain speed is reached, the liquid flows out of the centrifuge under the action of centrifugal force, so that part of the liquid is separated first. With the further increase of the motor speed, the load also decreases accordingly.

Main performance characteristics of centrifuge:

1. Can accurately control the speed and torque, and can match the existing standard squirrel cage asynchronous motor. With three control modes, namely scalar V/F control, sensorless vector control and torque control, this inverter is not only suitable for the simplest motor operation, but also can be applied in complex work situations. Its reliable overload capacity design can also meet both ordinary load and heavy duty work.

2. In the use of the centrifuge, the low speed starting torque is large, the starting is stable, and the separation factor is adjustable; It completely overcomes the disadvantages of traditional centrifuge such as high noise, high failure rate, short service life and unstable rotating speed. Can speed according to different process requirements, depending on the material easily select multistage speed operation, and adopts frequency conversion control for motor soft start to reduce the impact on the grid, the inverter has the rich such as overcurrent, overload, overvoltage protection function, when the abnormal load or motor frequency converter for downtime and rapid blockade output, so that can timely protect motor.
