| 摘 要： | 负载敏感系统是液压系统节能控制的主要环节之一.对一具有负载敏感系统的挖掘机在不同工况、不同负载压差,以及不同操作动作下泵的出口压力、流量进行了测试,分析了负载敏感系统工作特性,提出了压差的设定值应随负载的大小按正比例调节,以提高系统对负载的跟随性并减少波动.在标准负载工况下,压差设定为1.7MPa时,系统工作比较理想.

| Abstract: | A load-sensitive system is a crucial energy-saving component in a hydraulic system. Accordingly, the pump pressure and flow of an excavator was tested and analyzed on the basis of different working conditions, pressure differences and operation processes. To enhance the load responsiveness and reduce the pressure fluctuation, the pressure difference should be set in proportion to the loading pressure. Further elaborated, a pressure difference of 1.7 MPa is critical to the standard loading condition. |
