Francis Turbine Test Rig
The water enters the turbine through the
outer periphery of the runner in the radial direction and leaves the
runner in axial direction and hence it is called a mixed flow turbine.
As the water flows to the runner, a part of pressure energy goes on
changing into kinetic energy. Thus the water through the runner is under
pressure. The runner is completely enclosed in a air tight casing and
the casing & runner is always full of water.
The present set-up consists of a runner.
The water is fed to the turbine by Means of Centrifugal Pump, radially
to the runner. The runner is directly mounted on one end of a central SS
shaft and other end is connected to a brake arrangement.
The circular window of the turbine
casing is provided with a transparent acrylic sheet for observation of
flow on to the runner. Load is applied to the turbine with the help of
brake arrangement so that the efficiency of the turbine can be
calculated. A draft tube is fitted on the outlet of the turbine. The
set-up is complete with guide mechanism.
Pressure and Vacuum gauges are fitted at the inlet and outlet of the turbine to measure the total supply head on the turbine
