通过对负载敏感泵在煤矿铲运机液压系统上的节能机理分析,阐述了负载敏感泵在铲运车上的应用,得出了负载敏感泵的出口压力由负载决定,负载压力越高,泵的出口压力越高,其回路的效率就越高,液压回路的节能效果就越好。 By analyzing the energy-saving mechanism of load-sensitive pump on the hydraulic system of the coal scraper, the application of load-sensitive pump on the scraper is described. The outlet pressure of the load-sensitive pump is determined by the load. The higher the load pressure, the higher the pump pressure The higher the outlet pressure, the higher the efficiency of the circuit, the better the energy saving effect of the hydraulic circuit.
