摘要
分析了水泵调速运行的特点，指出市政工程中水泵调速运行的必要性，只有调节转速才能使水泵在各种情况下都运行在高效区，达到节能的目的。分析了晶闸管方波变频器与ＰＷＭ变频器的运行特点，并对水泵电动机变频调速装置的选型提出了看法。
Necessity of speed regulating operation of water pump in municipal engineering is pointed out. It can make the pump be operated in high efficient range under all circumstances. The operation feature of some frequency inverters are analyzed, and the selection of variable frequency invertor and speed regulation for water pump motor is discussed.
