DESCRIPTION

If flowing water is suddenly brought to rest in a long pipe, a phenomena known as water hammer occurs, wherein a pressure wave travels along the pipe. This principle is used in the hydraulic ram to pump water.

The Hydraulic Ram comprises an acrylic base incorporating pulse and non-return valves and a supply reservoir on a stand which is fed by the Hydraulics Bench. An air vessel above the valve chamber smooth’s cyclic fluctuations from the ram delivery. The weights supplied may be applied to the pulse valve to change the closing pressure and hence the operating characteristics.
