一般大中型水泵站都要安装两台以上的机组,为了满足一定的供水量,有时需两台或数台水泵同时运行.传统的流量分配方法大多只考虑每台泵尽量在高效区内运行,而没有从整个系统来优化.本文以分析离心水泵的流量功率特性曲线及其最优负荷分配为目标,给出水泵机组的最优负荷分配方法和最优起停次序.运用这一方法,可为水泵站的经济运行提供可行的途径.一、水泵机组流量优化分配目标和流量功率特性曲线 Generally large and medium-sized pump stations have to install more than two units, in order to meet a certain amount of water supply, and sometimes need to run two or more pumps at the same time.Most of the traditional flow distribution methods are only considered as much as possible in the efficient operation of each pump, But not from the whole system to optimize.In this paper, the centrifugal pump power flow curve and its optimal load distribution as the goal, given the pump unit optimal load distribution method and the optimal starting and stopping sequence.Using this method, For the economic operation of the water pump station to provide a viable approach.A pump unit flow distribution goals and flow characteristics of power curve
