Kaplan Turbine Test Rig

Generator/Alternator Type

digital tachometer tanks

The present set-up consists of a scroll casing housing a runner. Water enters the turbine Through the stationary guide vanes and passes through the runner axially. The runner has a hub and airfoil vanes, which are mounted on it. The water is fed to the turbine by means of centrifugal pump. The runner is directly mounted on one end of a central ss shaft and other end is connected to a brake arrangement. A transparent hollow cylinder made of acrylic is fitted in between the draft tube and the casing for observation of flow. Load is applied to the turbine with the help of rope brake arrangement so that the efficiency of the turbine can be calculated. The set-up is supplied with control panel. 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.
