Hydraulic Ram Test Rig

The Present set-up consists of a chamber incorporating pulse and non-return valves. This constant head tank gets water from the pump which draw water from sump tank. A fixed height over flow in constant head tank maintains the constant water head in the tank. An air vessel above the valve chamber smoothes cyclic fluctuations for the Ram delivery. Different pressure may be applied to the pulse valve to change the closing pressure and hence the operating characteristic. To measure the waste water, a measuring tank with flow diverter is provided. Flow of useful water delivered by the ram is measured with the help of measuring cylinder and stopwatch. A pressure gauge in delivery line of useful water is also provided to know the head of water. Present set-up is self-contained water re-circulating unit, provided with a sump tank, centrifugal pump etc. Water is pumped by means of centrifugal pump and passing through the overhead tank and ram chamber, it returns back to the sump which make the system re-circulating type.
