Francis Turbine Test Rig

The present Set-up consists of a runner. The water is fed to the turbine by Means  of centrifugal Pump, radically 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. The  circular window of the turbine casing is provided with a transparent acrylic sheet  for observation of flow on to the runner. The runner assembly is supported by  thick cast iron pedestal. 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 Set-up is complete with guide mechanism. Pressure and vacuum Gauge are fitted at the Inlet and Outlet of the  turbine to measure the total supply head on the turbine.
