Francis turbine

Our range of Francis turbines includes turbines in horizontal or vertical designs for medium to high head. The Francis runner is often fitted directly to the generator shaft, which also ensures a compact construction and low maintenance. Francis turbines are characterized by their optimal efficiency and high speed ranges. Francis turbine is widely used in hydro power stations with the head of 20-300 meters. It has a worm-shell structure which can make water in it flow easily and smoothly. Therefore, it is regarded as a type of turbine with high efficiency. It looks simple but it works well. Francis turbines are most widely used among water turbines and the development of the Francis turbines in the last decade has opened up a large range of new application possibilities for this type. These advances, motivated by a search for maximum profitability, have become possible as the result of improved knowledge of the water flows in turbines and other hydraulic phenomena.
