摘要
本文着重分析了水泵流量—扬程及流量—效率特性曲线,介绍了变频泵在供水系统中高效工作区范围,并且针对流量测量法和扬程测量法对水泵工作效率的测定产生的误差进行了分析。
The head-discharge curve and efficiency curve of a water pump was analyzed in this paper. The high efficiency working scope of variable frequency pump in a water supply system was introduced. The errors for measuring the working efficiency of the water pump by discharge measuring method and head measuring method were analyzed.
