適用于中低水頭，一般2－30米。其特點是水流流經(jīng)轉(zhuǎn)輪時始終沿著軸的方向。軸流式水輪機結構簡單，適用于中小容量、水頭及負荷變化較小的電站。
Axial turbine is applicable for middle and low head of 2 ~30 meters. The feature is that the flow shall go on along the direction of shaft while passing through the runner. This type of turbine is of simple structure,and appropriate to the power station of middle&small capacity with little head and load variation.
軸流式機組適用于低水頭水力資源的開發(fā)，使用水頭一般2~30m，有軸流轉(zhuǎn)槳式和軸流定槳式。
Axial turbines are suitable for low head 2 to 30 meters.They can be classifiesd into forms accrding to the structure of the runner:Propeller, with fixed blades, is used for small variation of head and power; Kaplan, with movable blades, is used for large variation of head and power.
