中文摘要：
利用最小二乘法对水泵性能曲线进行二次拟合,根据等扬程流量叠加原理建立了水泵并联运行曲线方程。对不同型号水泵配置的单调速泵站,通过建立的水泵并联调速运行方程和泵站的年供水规律,计算得到各供水指标下调速泵的调速比,可以实现完全通过改变水泵的特性来达到工况点改变的目的。
英文摘要：
The pump performance curve is fitted by the least square method.According to the principle of flow superposition at the same flow,a pump curve equation about parallel pump operation is established.To configure different types of single speed pumps,the laws on water supply which changes in different periods in pump stations are summed up and the speed ratio of the speed-governing pump is calculated under different indexes of water supply.Finally it can realize that a change in the operating point by changing the characteristics of pumps.
