Descrition:
The Francis type turbine is mostly suitable for hydropower stations
with medium or high head from 20m to 300m with higher average
efficiency. capable of running stably within 50%-100% rated output
and having a wide application in hydropower projects.
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.
They are in both vertical or horizontal shaft arrangement and could
be vastly selected by the hydraulic power stations.
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.
Francis turbine Applications:
1. Water head: 20-- 300m
2. Power: 0.1MW--- 30MW
3. Frequency: 50/ 60hz
4. Synchronous Generator Output Voltage: 0.4KV, 6.3KV, or 10.5KV AC
three phase,
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.
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.
Water head range for Francis Turbine selection.
