Francis Turbine Test rig
Francis Turbine Test Rig
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 S.S. shaft and the other end 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 draught
tube is fitted on the outlet of the turbine. The test 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 of the turbine.
