An Experimental Study on the Efficiency of the Water Hydraulic Piston Pump System driven by an Electric Inverter

전기 인버터 구동 수압 피스톤 펌프 시스템의 효율 성능에 관한 실험적 연구

A water hydraulic pump is likely to have serious problems of high leakage, friction and low energy efficiency. A water hydraulic pump has commonly a fixed displacement type and its outlet flow is adjusted by controlling rotation speed of the pump, which can be implemented by using an electric inverter. This study aims to investigate energy efficiency of the water hydraulic pump system which is driven by an electric inverter. The study is based on the experimental results. The pump which is used in the study shows relatively good efficiency and low leakage, low friction as well. The reasons for the good performance of pump is also investigated.
