摘要
定义离心泵的效率与管道系统效率的乘积为离心泵装置的效率，得到离心泵装置的最优工况点的流量小于离心泵最优工况点的流量的结果．离心泵叶轮的切削和变速调节的联合采用可进一步扩大离心泵的高效运行范围．
The efficiency of the centrifugal pump device is equal to pump efficiency times pipe system efficiency. The volume of the optimum operating point of the device is less than the volume of the optimum point of the pump.Lathing the wheet and regulating the rated speed of it can enlarge the higher efficiency range of the centrifugal pump.
