矿用挖掘机的故障与维修分析

Analysis on Fault and Maintenance of Mining Excavator

在建设高产高效煤矿的过程中,矿用挖掘机扮演着极其重要的角色,发挥着非常重要的作用,对矿用挖掘机的管理与维护,就提出了更高的要求。在分析了矿用挖掘机的工作原理后,从整机动作缓慢、挖掘装置故障、蓄能器故障、空调机不制冷、LS阀门故障等方面阐述了常见的故障及维修方法,对现场实践有一定指导作用。

In the process of building high production and high efficiency coal mine, mining excavator plays an extremely important role. It puts forward higher requirements for the management and maintenance of mine excavator. After analyzing the working principle of the mining excavator, the common faults and maintenance methods were expounded from the aspects of the slow movement of the machine, the fault of the excavator, the failure of the accumulator, the failure of air conditioner and the failure of the LS valve, which has some guidance for field practice.
