目前,工程上使用的神钢系列液压挖掘机主力机型多为-5型、-6型、-7型和-8型,除部分从日本进口外,多为成都的合资产品。神钢挖掘机控制系统由电子监控、发动机转速电子控制、先导压力传感泵流量控制、转速差泵流量控制等系统构成,采用机、电、液一体控制,其自动化程度高,设备工作性能优越。由于控制系统的复杂性,维护技术相对较高,有些故障原因十分简
At present, the main types of Kobelco hydraulic excavators used in the project are mostly Type-5, Type-6, Type-7 and Type-8, except for some imported from Japan and mostly Chengdu’s joint venture products. Kobelco excavator control system consists of electronic monitoring, electronic control of engine speed, pilot pressure sensing pump flow control, differential speed pump flow control system, the use of mechanical, electrical and hydraulic control, high degree of automation, superior performance equipment . Due to the complexity of the control system, maintenance techniques are relatively high and some of the causes of the malfunction are very simple
