日本加藤HD-900VⅡ型挖掘机系全液压传动,整机配合紧凑,操作灵活。使用一段时间后故障频繁,其表现为挖掘乏力,回转缓慢,铲斗、动臂均无力,伸缩动作过慢,整机行走吃力。从故障现象看,系因挖掘机动力输出不够,导致各工况动作缓慢。一、故障原因分析采取分段测试的方
Japan Kato HD-900V Ⅱ excavator hydraulic transmission system, the whole with a compact, flexible operation. Frequent use of the fault after a period of time, the performance of mining fatigue, slow rotation, bucket, boom are weak, telescopic action is too slow, the whole walk hard. From the fault phenomenon, the Department of excavator power output is not enough, leading to slow movements in all conditions. First, the cause of the failure to take the test section
