Pelton Wheel Turbine Test Rig (5HP output 15HP supply pump)
a) Test rig consists of a Pelton wheel water Turbine, designed for laboratory experimental purposes and to conduct test in metric units. The specifications of the turbine are as follows: -
Design Speed - 750-900 RPM.
Output Power - 3.7 kW. (5.0 HP)
Design Head and discharge - 46-50m and 700-900 lpm.
The turbine consists of a cast iron body with a large transparent acrylic window, a nozzle and spear arrangement, a bearing pedestal, a rotor assembly of shaft, runner and brake drum all mounted on a sturdy base. The Pelton buckets are made of gunmetal and the spear made of stainless steel for corrosion resistance. The input to the turbine is controlled by adjusting the spear position with a hand wheel fitted with an indicator arrangement. A rope brake arrangement with a set of dead weights and spring balance is provided for loading the turbine. The transparent perspex sheet side casing is provided for visual observation of flow on the buckets. Water inlet pressure is measured by a pressure gauge.
b) Water to the turbine is provided by a centrifugal monoblock pump set of 15 HP capacity of size. The pump operates on 440Volts, 3 Phase, 50 Hz line.
c) Other standard accessories include a star-delta starter, switch, flow control gate valve, suitable piping.
d) Flow measuring unit consists of a venturimeter of size 65mm with pressure taps connected to two pressure gauges mounted on a panel board.
e) The complete test rig is mounted on a storage tank of suitable capacity. The tank is provided with FRP lining for total rust protection
