Large Vertical Shaft Francis Hydro Turbine / Francis Water Turbine For Water Head From 20m To 300m

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.

Main Structure of Francis Hydro Turbine

This hydraulic turbine type is Horizontal shaft Francis. A inlet valve is equipped in front of the spiral casing of the turbine. When viewed at the turbine from the generator end, the rotating direction of the hydraulic turbine is clockwise .The turbine is horizontal shaft and metallic spiral casing and the stainless steel runner. This unit has two bearings, assembled on the generator seat. The principal parts of the structure of turbine as follows:

1)Spiral case 

2) Distributor

3) Rotating parts 

4)Inlet tube 

5) Draft tube 

6) Layout for water,instruments and pipe-line

Water flows through penstock of the power station, Butterfly valve, expansion pipe, inlet tube, spiral case and wicket gates into the runner, and then it drives the runner to revolve and convert hydraulic energy into mechanical energy and drives the rotor of generator revolution by the force of the main shaft of turbine, thus converting the mechanical energy into electric energy. 

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.
