Francis turbine is one of the most widely used turbines. It has a compact structure, reliable operation, and a high-efficiency range, usually from 85%-93%, and it can be used at different ranges of water flow. Our Francis turbines are commonly used at a hydraulic head range of 5-300 meters.
Product features :
1. Francis turbine has the advantages of compact structure,hight efficiency,can adapt to a wide range of water head of turbine types,is one of the widely used around the world.
2.When the water flow through the turbine wheel, it enters to radial, axial flow, so it is also called the radial axial flow turbine;
3.It is applicable to the head from a range of 20 meters of up to 700 meters, has the advantages of simple structure, stable operation, and high efficiency, but it is generally used in the head in the range(50 to 400 meters).
Single output from tens of KW to several 101000 tile.
At present this kind of turbine maximum output has exceeded 700000 kilowatts. A turbine is one of the most extensively used.
4.Mini francis turbines require lower head and flow, and are suitable for more low head and low flow power plants. The miniature Francis turbines provide electricity for mountainous areas, country houses and farms very conveniently

A mixed hydro turbine has radical inflow into a runner, axle outflow from the runner, which is referred to as Francis hydro turbine. The features of Francis turbine are simple structure and reliable operation; high efficiency, suitable for water head of 10 m-70 m, which is currently one of the most widely used. There is a vertical shaft and a horizontal shaft Francis turbine.
Francis turbine is designed for a wide range of water head and flow. Due to its high efficiency, Francis turbine had become the most widely used turbine in the world. Francis turbine operates at its best completely filled with water at all times. The turbine and the outlet channel may be placed lower than the lake or sea level outside, reducing the tendency for cavitation.
Francis turbine is a kind of turbine suit to water head 20-300meters and with the certain suitable flow.
1.It could be divided into vertical and horizontal arrangements. Francis turbines have the advantage of high efficiency, small size, and reliable structure.
2.Horizontal Francis turbine unit, with horizontal shaft, could be 2 or three supports. Which is normally one stair arrangement. Simple structure, easier operation, and maintenance.
3.Vertical Francis turbine unit, with vertical shaft, metal spiral case, or concrete spiral case. With adjustable guide vane, and stay ring, etc parts, are suited to runner diameter bigger than 1000mm. Our engineer will select the most suitable Francis turbine for your hydropower project.
