Performance of Pressure Divider Valves in Hydram Pumps with Variation of Divider Tube Length
Downloads
Air is the source of life for humans, plants and animals. One of the efforts to meet water needs is to use a hydram pump. A hydram pump is a pump that works without requiring external power to activate it, but this work is done by utilizing power from a water source. This study aims to determine the effect of using a pressure divider valve on the discharge of waste water and the discharge of water released by the hydram pump. This study used a hydram pump with the specifications of an air tube with a height of 60 cm and a diameter of 3 inches. The height of the waterfall from the pump body is 2 meters and the output height is 4 meters. The height of the air tube on the pressure divider is 20, 25, 30, 35, 40, 45 and 50 cm. The method used in this research is the experimental method. Quantitative data is made in tabular form and displayed graphically. The results showed that the highest wastewater discharge was 0.238 lt/s when using a tube length of 20 cm at an installation height of 2 meters from the pump body and the highest wastewater discharge was 0.232 lt/s when using a tube length of 50 cm. The highest water discharge that can be pumped is 0.0477 lt/s when a tube length of 20 cm is used. While the lowest water discharge pumped was 0.0398 lt/s occurred when using a tube length of 50 cm.
