Mainly , the type of pump in the large - scale irrigation and drainage pumping station in our country is adjustable - blade propeller pump . we can regulate the pump ' s blade mounting angle following the variation of water level at the inlet and outlet of the station in order to control the discharge of pump , we also determine the number of running machines with machine ' s optimal combination . so we can reduce its energy consumption , and make it optimally and economically run
我国大部分大型电力排灌站所安装的泵都为可调节叶片的轴流泵，这一有利条件使我们可以根据排灌站进、出口水位的变化来调节水泵的叶片角度，控制水泵的流量，并合理的确定开机台数，通过机组间的优化组合，使整个泵站的能耗最少，达到整体最优、经济运行的目的。
When the water head and the flow are given , we can regulate the pump ' s blade mounting angle to control the discharge of pump in this pumping station that contains only one type of pump . we also can determine the number of running machines with machine ' s optimal combination . so we can reduce its energy consumption , and make it run optimally and economically
当水头和抽水流量给定时，这类泵型单一的泵站，可以通过调节水泵的叶片角度，控制水泵的流量，并合理确定开机台数，通过机组间的优化组合，使整个泵站的能耗最少，达到整体最优、经济运行的目的。
