基于水泵流量控制与变频调速技术应用的研究

The Research Based on Water Pump Flow Control and Frequency Conversion Velocitymodulation Technology Application Research

文章介绍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两种方案,及这两种控制方案的原理和特点;论述了交一直一交三相变频器的结构组成、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。

This article introduced the commonly used two kinds of plans in the centrifugal pump flow control ： control pump exports the valve opening and controls the pump the rotational speed, and these two kind of control plan＇ s principle and characteristic ; the research elaborated three intersections to hand over the three - phase frequency changer continuously the structure composition, the principle of work and exterior wiring, and has pointed out the frequency conversion velocitymodulation flow control application and the effect.
