DESCRIPTION:

The Set-up is designed to study the Hydraulic Ram. Hydraulic RAM is used for pump little quantity of water to high head from a large quantity of water available at low head. It works on a principle of water hammer stating that “When flowing water is suddenly stopped in a long pipe a pressure wave travels along the pipe creating an effect of water hammer”. The Set-up consists of a pipe section fitted with a pulse valve and non-return valve, a supply reservoir on a stand which is connected to an overhead tank, an air vessel above the valve chamber smoothes cyclic fluctuations from the Ram delivery. Different pressure may be applied to the pulse valve to change the closing pressure and hence the operating characteristic. The flow rate of useful and waste water is measured using measuring tank and stop watch provided. Pressure and Vacuum Gauge are connected on delivery and suction side for the purpose of measurement.

DESCRIPTION:

Pelton Wheel Turbine is only impulse water turbine now in common use named in honor 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 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 providing 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.
