摘　　要：在变频调速给水设备选型设计中,往往偏重主泵的选型,而忽视气压罐与辅泵的选型计算,导致在小流量运行时节能效率偏低。介绍4种常见变频调速给水设备在小流量运行模式下的工作原理、系统配置以及优缺点等,结合实例分析了气压罐和辅泵设计选型的基本原则和注意事项。In the design of the frequency control water supply device, emphasis always was put on the pump type selection but the selection and calculation of the pressured air tank and assistant pump were ignored. This might lead the relatively low efficiency under small flow rate operation. This paper introduced the working principles, system configuration, advantage and disadvantage of four common frequency control water supply devices under the small flow rate operation. Based on practical example, this paper analyzed the basic principles and notes for the pressured air tank and assistant pump design selection.
