1MW 5MW Hydro Electric Francis Water Turbine For Hydropower Plant

5MW Hydro Electric Francis Turbine Generator On The River Dam

Features of Francis Turbine

Francis turbine has compact structure, high efficiency, and can adapt to a wide range of heads. It is currently one of the turbine models widely used in various countries in the world. When water flows through the working wheel of this kind of hydraulic turbine, it enters in the radial direction and flows out in the axial direction, so it is also called radial axial flow turbine.

It is suitable for the range of water head from 20 meters to 700 meters. It has simple mechanism, stable operation and high efficiency, but it is generally used in the range of medium head (50 meters to 400 meters). The output of a single machine ranges from tens of kilowatts to hundreds of thousands of kilowatts. At present, the maximum output of this kind of turbine has exceeded 700,000 kilowatts. It is the most widely used hydraulic turbine.

Composition of Francis Turbine

The structure of a Francis turbine includes a volute, a seat ring, a water guiding mechanism, a top cover, a runner, a main shaft, a guide bearing, a bottom ring, a draft tube, etc., as shown in Figure 1, which also indicates the flow direction of the water. The volute is a water diversion part, shaped like a snail shell, and is generally made of metal with a circular section. The seat ring is placed between the volute and the guide vane and consists of an upper ring, a lower ring and a number of uprights, which are directly connected to the volute; the uprights are wing-shaped and cannot rotate, and are also called fixed guide vanes. The water guide mechanism is composed of movable guide vanes, speed control ring, crank arm, connecting rod and other components.
The runner is directly connected to the main shaft and is the rotating part of this type of turbine. The runner is composed of an upper crown, a lower ring, a drain cone and a number of fixed blades. Its shape and the matching dimensions of each component are determined by the different heads used. Different. The draft tube is the water-discharge part of the turbine that guides the water flow from the runner outlet to the downstream. It is generally elbow-shaped. A straight cone-shaped draft tube is commonly used in small hydraulic turbines.
