Stainless Steel Francis Turbine Runner

Stainless Steel Francis Turbine Runner

The Francis  turbine is mostly suitable for hydropower stations with medium or high head from 10m to 300m. They are in both vertical or horizontal shaft arrangement and could be vastly selected by the hydraulic power stations.

lts feature is that the water flow enters the runner inward in a radial direction , changes direction gradually and then passes out axially. Francis Turbine is characterized by reliable operation, simple construction and high efficiency, etc. Hydoru manufacture Francis runner have a good efficiency and cavitation performance.

Normally, we adopt the horizontal Francis with capacity below 5MW, runner diameter below 90cm. And the vertical Francis with capacity below 20MW.

 

Applications:

Francis turbines are the most common Water Turbine in use today.

They operate in a water head range of 10 to 300 meters and are primarily used for electrical power production. The power output generally ranges from 100KW to 750MW.

Normally, Medium size and larger Francis turbines are most often arranged with a vertical shaft, Small francis turbine always arranged with horizontal shaft, but it is not absolute.

Francis turbines are also called Francis turbines. The water flows radially from all sides into the runner, and then flows out of the runner approximately axially. The runner is composed of an upper crown, a lower ring and blades. The Francis turbine has compact structure, high efficiency, and can adapt to a wide range of heads. It is currently one of the turbine types widely used in countries around the world. When the water flows through the working wheel of this kind of turbine, it enters in the radial direction and flows out in the axial direction, so it is also called radial axial flow turbine.
The Francis turbine runners produced by our company are divided into integral forging integral CNC machining runners and casting and welding runners.
