故障的现场检测与诊断
（1）现场的初步检查与诊断
根据故障现象查清有关情况，对照液压系统图分析产生故障的部位和初步原因，不可忽视看起来十分简单的原因，更不可盲目乱拆，以免造成不必要的损失。在具体的检查过程中应扫以下步骤进行。
①向驾驶员了解情况，对故障产生时机器的状态，声音等都要做详尽了解，避免了小题大做，化易为难。如一台966D装载机，在给变速器换完油后发现机器行走无力。变矩器油温过高。经检查发现，所加传动油号错误，在弄清了引发故障的原因后，故障得以迅速排除。
②进行必要的具体操作。有时，驾驶员对机器故障的因果关系陈述不清，致使故障诊断困难，这时进行必要的现场操作将获益匪浅。
③油质、油量的检查。此内容看似简单，社施起来却常被忽视。如一台966D装载机（其行走机构为液压力传动系统），驾驶员放假时已将变速器油放完。待工地搬迁后助手来开车时，发现机器不能行走，原以为是出了大故障，但维修人员在现场只作凭听声音、检查油尺就解决了问题，避免了大事故的发生。又如，一台日立EX220-2挖掘机，在修理完液压缸后发现液压油不足，而现场采购的液压油为土法提炼的再生油，续加到油箱后造成了油质的污染。变质起泡，致使机器动作无力，更换液压油后故障得以排除。对油质，油量的检查必须引起足够的重视；否则将烧坏液压泵，损坏传动系统。
④检查各种滤芯。滤油器是液压系统的清洁工具，在故障诊断时，检查滤油器（台滤油器的脏污程度、滤芯上各种杂质的性状等）可为分析故障提供依据。如一台加腾HD820型挖掘机，在运转了4000h左右后发现整机无力；拆检其液压系统滤油器时，发现滤芯损坏，堵住了回油口，更换滤芯后故障得以排除。
如果通过以上的初步检查后仍不能排除故障，则应借助仪器做更为详细的检测。
