Axial flow type turbine generator set

Axial flow turbine generator unit: water flows in axle direction and flows out making the wheel rotate. Axial flow turbine can be divided into fixed vane and Kaplan turbine according to the structure of runner. The axial flow turbine is suitable to water head of 3m-10m.
The fixed vane type is normally used for medium and small power plant and water head with relatively small change ,Features :simple structure, When deviating from the designed operation conditions. there will be drastic downgrade of effect.
The Kaplan type is mainly used for big and medium plants, water head power plant with relatively big change .Features :Wide range of high efficiency area as coordinated control of vane and guide vane is achieved, it has relatively complex structure as it requires control mechanism of runner vane.
