挖掘机液压系统控制性能分析

Analysis of Control Performance of Hydraulic System of Excavator

介绍了挖掘机液压系统的功率参数与流量控制机理,从液压系统的功率角度分析了液压挖掘机的功率控制方式,从挖掘机负流量液压系统与正流量液压系统的工作原理方面分析了其控制性能及优缺点,并总结了挖掘机负流量液压系统与正流量液压系统的技术价值、应用场合及改善方向。

The paper introduced the power parameters and flow control mechanism of the hydraulic system of excavator,derived the power control modes of the hyduaulic excavator,analyzed the advantages and disadvantages of the positive flow control and negative flow control of excavator from the working principle of hydraulic system.At last,it summed up the,application and improvement direction of the hydraulic system control mode of excavator.
