在处理故障时，可按下述步骤进行。
(1)查找故障液压元件
液压系统的故障有时是系统中某个元件产生故障造成的，因此，首先需要把出了故障的元件找出来。根据下列步骤进行检查，就可以找出液压系统中产生故障的元件。
第一步，确定液压传动设备运转不正常的现象，是没有运动，仍是运动不不乱;是运动方向不准确，仍是运动速度不符合要求;是动作顺序错乱，仍是输出力不不乱;是泄漏严峻，仍是爬行等。不管是什么原因，都可以归纳为:流量、压力和方向三大题目。
第二步，审校液压回路图，并检查每个液压元件，确认它的机能和作用，初步评定其质量状况。
第三步，列出与故障相关的元件清单，逐个进行分析。进行这一步时，一要充分利用判定力，二是留意毫不可漏掉对故障有重大影响的元件。
第四步，对清单中所列出的元件按以往的经验和元件检查的难易排列次序。必要时，列出重点检查的元件和元件的重点检查部位。可同时利用仪器进行丈量。
第五步，对清单中列出的重点检查元件进行初检。初检应判定以下一些题目:元件的用途和装配是否合适;元件的丈量装置、仪器和测试方法是否合适;元件的外部信号是否合适，对外部信号是否响应等。特别留意某些元件的故障先兆，如过高的温度和噪声、振动和泄漏等。
第六步，假如初检中未查出故障，要用仪器反复检查。
第七步，识别出发生故障的元件。对分歧格的元件进行修理或更换。
第八步，在重新启动主机前，必需先当真考虑一下这次故障的原因和后果。假如故障是因为污染或油温过高引起的，则应预料到其他元件也有泛起故障的可能性，同时对隐患采取相应的措施。例如，因为污染原因引起液压泵的故障，则在更换新泵前必需对系统进行彻底清洗和过滤。
(2)重新启动
排除液压系统故障之后，不能操之过急，盲目启动，必需遵照一定的要乞降程序启动。否则，旧的故障排除了，新的故障会接踵产生。其主要原因是缺乏周密的思索。如前所述，液压泵因为污染而泛起故障，那么，污染是怎样引起的?其他液压元件是否也被污染了呢?

Processing failure, according to the following steps.
( 1 ) Finding fault hydraulic components
Hydraulic system failure the system is sometimes caused by a component failure , therefore , a first need to find out the faulty component . According to the following steps to check the hydraulic system can be generated to identify the failed component .
The first step to determine the hydraulic transmission equipment does not operate a normal phenomenon , there is no movement , no movement is still not chaos ; movement direction is inaccurate velocity is still not meet the requirements ; action sequence disorder is still the output power is not without chaos ; was severe leakage is still crawling and so on. Whatever the reason , can be summarized as follows: flow, pressure and direction of the three topics .
The second step, revisers hydraulic circuit diagram and check each hydraulic components, make sure it 's functioning and role of the preliminary assessment of their quality status .
The third step is associated with the failure of the components listed in the list to be analyzed individually . When doing this , one is determined to make full use force , and second, pay attention to no fault can have a significant impact on the missing elements .
The fourth step, are listed in the inventory component based on past experience and the difficulty of checking components arranged in order. If necessary, check the list of key elements and components focus on examination area. While taking advantage of the instrument can measure .
The fifth step, focusing on the list, check the components listed in the beginning of the seizure . Initial inspection should determine the following some of the topics : the use of components and assemblies is appropriate ; component measuring apparatus , instruments and testing methods are appropriate ; components external signal is appropriate, whether the response to external signals and so on. Special attention to the failure of certain components aura , such as high temperature and noise , vibration and leakage .
The sixth step, if not detected early detection of faults , to use the instrument repeatedly checked.
Seventh step , to identify the faulty component . Differences in cell components for repair or replacement.
Eighth step, restart the host , you must first seriously consider the causes and consequences of this failure . If the failure is caused because of pollution or high oil temperature , and other components should be expected to have thrown up the possibility of failure , while the risks to take appropriate measures . For example, because of pollution caused pump failure , then the replacement of the system is required before the pump thoroughly cleaned and filtered.
( 2 ) Restart
Exclude hydraulic system failure , you can not be rushed, blindly start , must follow certain procedures to beg to surrender start . Otherwise , the old troubleshooting , the new fault will be generated after another . The main reason is the lack of careful thought. As mentioned earlier, because of pollution and thrown pump failure , then the pollution is caused by what ? Whether other hydraulic components also is polluted it ?
