挖掘机W1002是中小型露天矿山的主要设备之一。我公司有8台W1002型挖掘机,但长期以来其液压操作系统泄漏一直是比较棘手的问题,多处泄漏导致挖掘机平台以上到处堆油泥,平台以下到处滴“油雨”。液压油消耗严重超标。 从现场的情况看,液压油泄漏的主要途径一是操作油路中多处管接头频繁损坏,造成泄漏;二是操作阀和动作油缸密封失效,造成泄漏。 1 原因分析 Excavator W1002 is one of the major equipment for small and medium open pit mines. My company has eight W1002 excavators, but for a long time its hydraulic operating system leakage has been a tricky issue, resulting in multiple leaks above the excavator platform piles of sludge everywhere, below the platform drops “rain.” Excessive hydraulic oil consumption. From the scene of the situation, the main way to leak hydraulic oil is the frequent damage to the pipe joints in the operation of many, resulting in leakage; the second is the operating valve and cylinder seal failure, resulting in leakage. 1 reason analysis
