Hydraulic Ram Test Bed
Product Code : EL-FMLE-10664
QUICK ANSWER: The Hydraulic Ram Test Bed demonstrates a hydraulic ram pump – a device that uses the momentum of a large flow of low-velocity water (acting like a ‘plunger’ in the supply/drive pipe from a header tank) to pump a smaller amount of water up to a higher head, without any energy source except the flowing water itself, by exploiting the water hammer effect that occurs when flowing water is suddenly brought to rest in a long pipe. The apparatus comprises an acrylic base with stainless steel pulse and non-return valves, an air vessel that smooths cyclic fluctuations in the ram’s delivery, and an adjustable acrylic header tank connected via a quick-release fitting to the Hydraulics Bench, which supplies and measures the water; weights can be added to the pulse valve to change its closing pressure and vary the operating characteristics, over a variable supply head of 300-700mm and delivery head of 750-1500mm.
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 smooths cyclic fluctuations from the ram delivery. A ram pump is a type of pump which delivers water at high heads without any energy source except flowing liquid at some height, using the momentum of flowing water for its operation; the weights supplied may be applied to the pulse valve to change the closing pressure and thus the operating characteristics. If flowing water is suddenly brought to rest in a long pipe, a phenomenon known as water hammer occurs, wherein a pressure wave travels along the pipe, and this principle is used in the hydraulic ram to pump water.
The ram pump is not a normal mechanically-operated pump. A column of water in the supply (drive) pipe from a header tank, moving at low velocity, is similar to a ‘plunger’; the energy in the plunger forces water from the supply into a delivery pipe, exchanging the momentum of a large amount of water into energy that pumps a smaller amount of water up a hill or gradient. The apparatus has three main parts: the header tank, the pump and the interconnecting pipe work; the header tank mounts to a suitable wall. This apparatus is used to study the phenomenon and performance of the hydraulic ram pump.
