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 但在一些復雜泵站中,同時存在著可調(diào)節(jié)葉片的軸流泵和不可調(diào)節(jié)葉片的軸流泵。
The axial - flow turbine generator set is suitable for low head from 2m to 70 . its feature is that the water flow passes through the runner axially . the axialflow turbine generator set can be classified into two forms according to the runner construction : one is fixed blades propeller for small variation of head and power , the other is movable blades kaplan for large variation of head and power 貫流式水輪發(fā)電機組是低水頭大流量電站的較好機型,一般適用于水頭2 ~ 15米,其特點是水流從進水口到尾水出口都是軸向的,流道基本上成直線,因而貫流式水輪發(fā)電機組具有水流特性好,效率較高等特點。
