The industrial centrifuge is one of the main equipments in the chemical industry. It mainly separates the solid and liquid through centrifugal force. According to the process characteristics, the material is mainly a solid-liquid mixture at the beginning, and the load is relatively large when it is just started. Under the action of centrifugal force, it flows out from the outside of the centrifugal force, so that part of the liquid is first separated, and with the further increase of the motor speed, the load is also reduced accordingly. The D32 frequency converter can meet the technological requirements and realize the separation effect of running at several different speeds. As an industrial control equipment, it has a wide range of applications in industrial centrifuges.
