摘　　要：针对供水管网定压调流量的需求,阐述多台水泵需要进行变频调速的搭配运行,合理分析水泵的P-Q曲线,从而实现设备选型贴合工艺运行工况的需求。In view of the demand of constant pressure and flow regulation of water supply network,this paper expounds that multiple pumps need to operate with frequency conversion and speed regulation,and reasonably analyzes the P-Q curve of water pumps,so as to realize the requirements of equipment selection and process operation conditions.

关 键 词：变频调速 定压调流量 送水泵 P-Q曲线
