新型液压多泵在液压调速系统中的节能分析
Research on Energy-saving Methods for Hydraulic Speed-regulating Curcuit Based on Multi-pump
摘要
Abstract
Based on a new hydraulic component（multi-pump）,several noval speed-regulating circuits were proposed.The core component of these circuits is multi-pump in which more pumps with different flows are formed.It has more inlet ports and more outlet ports,according to various working conditions of the actuator needed,it changes the connection of pipes,which makes the pumps output power match the load power reasonably,by doing so,the problem of too much power loss can be solved.The operating principle of single-acting multi-pump and double-pressure throttle speed-regulating circuit,the double-acting multi-pump digital control inlet throttle speed-regulating circuit and the double-acting multi-pump digital control stepless speed-regulating circuit were stated,then the power performance of the multi-pump digital control inlet throttle speed-regulating circuit under constant load was analyzed.The results show that these curcuits reduce the loss of power and improve the efficiency.关键词
