HYDRAULIC RAM TEST RIG

PRODUCT DETAILS

Description

The present set-up is designed to study the Hydraulic Ram. Hydraulic Ram is used for pumping small quantity ofwater at high head, when large quantity of water at smallhead is available. It operates on the principle that ifflowing water is suddenly brought to rest in a long pipe, aphenomenon known as water hammer occurs, wherein apressure wave travels along the pipe. This principle isused in the Hydraulic Ram to pump water. The set-upconsists of a chamber incorporating pulse and non-returnvalves. This constant head tank gets water from the pumpwhich draw water from sump tank. A fixed heightoverflow in constant head tank maintains the constantwater head in the tank. An air vessel above the valvechambersmoothes cyclic fluctuations for the Ramdelivery. Different pressure may be applied to the pulsevalve to change the closing pressure and hence theoperating characteristic. To measure the waste water, ameasuring tank with flow diverter is provided. Flow ofuseful water delivered by the ram is measured with thehelp of measuring cylinder and stopwatch. A pressuregauge in delivery line of useful water is also provided toknow the head of water.Present set-up is self-contained water re-circulating unit,provided with a sump tank, centrifugal pump etc. Wateris pumped by means of centrifugal pump and passingthrough the overhead tank and ram chamber, it returnsback to the sump which make the system re-circulatingtype. Flow of water is diverted either to measuring tankor sump tank with the means of a flow diverter, whenneeded. The supplied set-up is complete in all respect.Only water supply and electricity supply is to be providedby the end user for running the set-up.
