摘　　要：基于目前市场上的挖掘机液压系统,详细介绍了应用最为广泛的负流量控制、正流量控制和负载敏感控制的结构特点以及工作原理,并针对负载敏感控制中的压力补偿器的位置不同,介绍了阀前压力补偿系统和阀后压力补偿系统的区别和各自的特点;对3种系统进行比较,做出归纳总结。研究结果表明:3种系统在节约能源上都有一定的效果,但是各个系统的特点又有不同之处。Based on the current market excavator hydraulic system,the article introduces the structural characteristics and working principle of negative flow control,positive flow control and load sensitive control.According to the different position of pressure compensator of the load sensitive control,the article introduces the difference and respective characteristics before and after the valve pressure compensation system.We compare three kinds of systems and make generalizations.The research results show that three kinds of system has a certain effect on saving energy,but the characteristic of each system is different.
