Solution: The axial flow turbine runner is composed of a runner body, a blade and a water discharge cone. The number of blades is less than that of the mixed flow type, and the blade axis is perpendicular to the axis of the turbine. It is suitable for hydropower stations with medium and low heads and large flow. The flow of water changes from radial flow to axial flow between the vanes and the runner, while in the runner region, the flow of water remains axial.

1. Suitable for the head range of 2m~45m.

2. The output range is 0.5MW~50MW.

3. It has higher specific speed and strong overcurrent capability. Under the same conditions, the output is large.

4. The propeller type can automatically adjust the blade angle with the change of the head and load, and has a wide high efficiency zone.
