Pelton Wheel Turbine Test Rig (HD-47)


Pelton Wheel Turbine is only impulse water turbine now in common use named in honour of Sir L.A. Pelton (1829- 1908) of California, USA. It is a tangential flow impulse turbine. The water strikes the buckets along the tangent of the runner. The energy available at the inlet of the turbine is only kinetic energy. The pressure at the inlet and outlet of the turbine is atmospheric. This turbine is used for high heads. The present set-up consists of a runner. The buckets are mounted on the runner. The water is fed to the turbine, through SS nozzle with a SS spear, by means of Centrifugal Pump, tangentially to the runner. Row of water into turbine is regulated by adjusting the spear position by the help of a given hand wheel 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 buckets. This runner assembly is supported by rigid MS structure. Load is applied to the turbine with the help of this brake dynamometer so that the efficiency of the turbine can be calculated. Pressure gauge is fitted at the inlet of the turbine to measure the total supply head to the turbine

Experiments
  • To study the operation of a Pelton Wheel Turbine
  • To determine the Output Power of Pelton Wheel Turbine
  • To determine the Turbine Efficiency

Utilities Required
  • Water Supply and Drain

Francis Turbine Test Rig (HD-48)


Francis Turbine is a reaction turbine, which was developed by an English born American Engineer Sir J. B. Francis. 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

Experiments
  • To study the operation of a Francis Turbine
  • To determine the Output Power of Francis Turbine
  • To determine the Turbine Efficiency

Utilities Required
  • Water Supply and Drain
  • Electricity 1.5 kW, 440V AC, Three Phase
  • Floor Area 1.5 x 0.75 m

Kaplan turbine test rig (HD-49)


Kaplan Turbine is an axial flow reaction turbine named in honour of Dr. B. Kaplan, a Gennan Engineer. This turbine is suitable for low head. The power produced by a turbine is proportional to QH. As the head (H) decreases the J discharge (Q) must increase to produce the same power. 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
