A study on the efficiency improvement of electro-hydraulic pump system by load sensing

부하센싱에 의한 전기유압펌프시스템의 효율 향상에 관한 연구

Variable-displacement pumps are inherently more efficeint than fixed-displacement pumps under varying loads. Their energy-saving characteristics can be improved by the use of special control. This paper shows the improvement of the system by the use of load-sesing technique.
