摘　　要：将负荷传感控制挖掘机主泵输出流量技术与压力补偿实现挖掘机复合动作时的流量分配技术两者同电子控制技术相结合,使液压挖掘机在按需供油、节能降耗以及改善操纵性等方面取得显著效果。对此项技术做了系统的分析与探讨,为挖掘机液压控制系统国产化提供参考。Load-sensing controls the flow volume out of the main pump on excavators and flow-diverging is accomplished by pressure compensation when excavator is in combined operation. Combining the two with electronic control technology, excavators can present remarkable advantages in the aspects of oil-feeding on demand, energy-saving and fuel consumption, and controllability improvement. The technology is systematically analyzed and discussed in the article, which provides a reference for the localization of hydraulic control system on excavators.
