Vertical Shaft Francis Hydro Turbine for water head from 20m to 300m
Descrition:
The Francis type turbine is mostly suitable for hydropower stations with medium or high head from 20m 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.
Normally, we adopt the horizontal Francis with capacity below 5MW. And the vertical Francis with capacity below 30MW.
Applications:
1. Water head: 20m -- 300m
2. Power: 0.1MW -- 30Mw
3. Frequency: 50hz / 60hz
4. Generator Output voltage: 0.4KV, 6.3KV, or 10.5KV AC three phase,
Francis turbines may be designed for a wide range of heads and flows. This, along with their high efficiency, has made them the most widely used turbine in the world. Francis type units cover a head range from 20 to 700 meters (100 to 2,300 feet), and their output power varies from just a few kilowatts up to one gigawatt. Large Francis turbines are individually designed for each site to operate at the highest possible efficiency, typically over 90%
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.
If you are interested in the Francis turbine, you should send some key parameters (such as net head, flow discharge, unit number, frequency, voltage) in inquiry.
