400kw francis hydro turbine efficiency 95% 50HZ

Francis turbine of Hongya Hydro Generator the water head range is 15m to 300m, capacity from 100kw to 6000kw for each single unit.

1. Spiral Casing
Spiral casing is the inlet medium of water to the turbine. The water flowing from the reservoir or dam is made to pass through this pipe with high pressure. The blades of the turbines are circularly placed, which mean the water striking the turbines blades should flow in the circular axis for efficient striking. So the spiral casing is used, but due to circular movement of the water, it looses its pressure.

To maintain the same pressure the diameter of the casing is gradually reduced, so as to maintain the pressure uniform, thus uniform momentum or velocity striking the runner blades.

2. Stay Vanes

The stay vanes and guide vanes direct the water to the runner vanes. The stay vanes remain stationary in their position and reduce vortices due to radial flow as water enters the runner vanes. Thereby improving the efficiency of the turbine.

3. Guide Vanes
The guide vanes are not stationary, they change their angle as required to control the angle of impact of the water on the turbine blades, thus increasing efficiency. They also regulate the flow rate of water entering the runner blades, thereby controlling the power output of the turbine based on the load on the turbine.

4. Runner Blades
The performance and efficiency of a turbine depends on the design of the rotor blades. In a turbine, the runner blades are divided into two parts. The lower half is made in the shape of a keg so it uses the pulsing action of the water to spin the turbine.
The upper part of the blade utilizes the reaction force of the water flowing through the blade. These two forces combine to spin the wheel.

5. Draft Tube
The pressure at the outlet of the reaction turbine runner is usually less than atmospheric pressure. The water at the outlet cannot be discharged directly to the tailrace. Use pipes or pipes of increasing area to discharge water from the turbine outlet to the draft ring.
This tube of increasing area is called a draft tube. One end of the pipe is connected to the outlet of the runner, while the other end diverts the flow below the level of the tailrace.
