摘　　要：为在城市供水系统中引用变频调速节能技术,以水泵特性曲线和管路特征曲线为依据,用图示的方法对影响调速范围、节能效果的一些主要因素进行了分析和探讨,并指出了变频调速的适用范围.In order to use the technique of variable frequency speed-regulating in the water supply system of city. At first the factors which affect the variable frequency range and saving energy by graphic method with the head curve of pump and the pipe resistance curve are analyzed and discussed. At last, the practicable range of variable frequency speed-regulating is given.
