通过对城市水厂二泵站中定速泵、调速泵、定速泵与调速泵并联运行三种压力供水方式适用范围的分析，从节能的角度出发，根据工作水泵高效运行的原则，分别给出了水泵优化选择的方法，并通过具体实例进行了探讨。

In this paper, the suitable conditions of using constant speed pumps, variable speed pumps or combination of both in the secondary pump station of water works are analyzed. Then, from the point view of energy saving and based on the principle of high efficiency operation, the method for selecting pumps in the secondary pump station of water works is provided. Eventually, the method is examined with examples.
