摘　　要：发电厂在运行中随时调节负荷，包括各系统流量，涉及到离心泵的流量变化．对离心泵定速和变速两种运行方式调节流量时的耗能和效率分析结果表明：变速调节方式耗能少，且经济效益好．Power plants regulate the load and the now of systems in running at any time, which involves the flow change of the centrifugal pumps. The energy consumption and efficiency of the centrifugal pump which works at constant and changing speed flow regulating are analysed. The results of calculation show that changing speed regulating mode consumes less energy and has better economic profit.
