WATER HAMMER PHENOMENON, PERFORMANCE OF A HYDRAULIC RAM PUMP
The Hydram uses the water hammer effect where by the energy of a large amount of water falling from a small height to lift a small amount of this water to a much greater height. The design and fabrication of a hydraulic pump (hydram) was undertaken using commercial available material and its performance and pressure fluctuation were studied. The aim of this study is to develop a hydraulic ram pump that would be appropriately improving the problem of water supply to the local communities. Two types of hydraulic pump were constructed with different chamber volume, water supply and delivery heads and flows, stroke and the weight of impulse valve. Three experiments for each pump were conducted and data was analyzed. To improve the performance of hydram, most important problems is tuning of the valves during operation. These results will enable targeted users to be able to select appropriate sizes for their water pumping needs. The performance of hydram with two different volume of air chamber was tested. The results show that using 14cm3 and 19cm3 of air chamber, the performance of hydraulic pump was 62.5% and 59.7% respectively.
