摘要
介绍了扬程特性、管阻特性和水泵效率的相对值近似表达式。并据此分析了变频调速供水系统与阀门调节供水系统相比较的节能效果，和进行近似计算的方法，提出了针对实际工况应作的修正。
：The paper introduces the approximate formula for the head curve of pump, the pipe resistance curve of system and the efficiency of pump with relative value. And uses these formula, compares with the effect to save energy of the speed control and the valve control for water supply. Introduces the method of approximate calculation. Poses a correct method of the actual situation.
