【 摘 要 】

Hydraulic ram pump is device that can lift water to the higher position without use of external energy. Several ways have been tested to decrease the water waste rate to maximize efficiency. The purpose of this research work is to develop a new design of hydraulic pump and conduct simulation study to justify improvement of the design. Major addition on making threaded waste valve system in order to control the opening and closing of the valve. At the same time reduce time taken for creating enough momentum and hammering effect. The results revealed that with the advancement of the proposed well improve designs, the water losses at waste valve reducing about 20-30% compare to existing design across the mass flow rate of 0.10 kg/s.The min/max velocity and pressure along the pipeline also has been increase for both open and closed condition.
