摘　　要：介绍了常用的控制泵的出口阀门开度和控制泵的转速的离心泵流量控制方案,论述了三相交—直—交变频器的结构组成、工作原理和外部接线,并指出了变频调速流量控制的应用及效果。The paper presents the traditional flow control method of the centrifugal pump through controlling the discharge valve opening size and rotational speed of the pump, as well as three - phase AC - DC - AC frequency converter＇s composition, working principle and the external wiring diagram. It also describes how the pump flow is controlled by the frequency converter and the actual application effect.
