Francis Turbine Test Rig Description and Specifications for Lab Tenders
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 and 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
