摘要
研究了变频调速技术在离心泵流量控制中的应用,阐述了离心泵流量控制中常用的控制泵的出口阀门开度和控制泵的转速的两种方法,以及这两种控制方法的原理和特点;介绍了三相交—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效果。
The application of frequency control technique on the centrifugal pump flow control is researched. Two kinds of methods used commonly to control opening of outlet valve and rotational speed are elaborated. The principles and characteristics of the methods are presented as well. The structure composition, working principle and characteristics of a frequency converter with three-phase of AC-DC-AC are introduced. Finally, the application effect of flow control is pointed out.
