But there are some complex pumping stations that contain two kinds of pumps . one is flexsible - blade propeller pump , the other is fixed blade propeller pump
但在一些复杂泵站中，同时存在着可调节叶片的轴流泵和不可调节叶片的轴流泵。
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。
