在處理故障時,可按下述步驟進行。
(1)查找故障液壓元件
液壓系統的故障有時是系統中某個元件產生故障造成的,因此,首先需要把出了故障的元件找出來。根據下列步驟進行檢查,就可以找出液壓系統中產生故障的元件。
第一步,確定液壓傳動設備運轉不正常的現象,是沒有運動,仍是運動不不亂;是運動方向不準確,仍是運動速度不符合要求;是動作順序錯亂,仍是輸出力不不亂;是泄漏嚴峻,仍是爬行等。不管是什么原因,都可以歸納為:流量、壓力和方向三大題目。
第二步,審校液壓回路圖,并檢查每個液壓元件,確認它的機能和作用,初步評定其質量狀況。
第三步,列出與故障相關的元件清單,逐個進行分析。進行這一步時,一要充分利用判定力,二是留意毫不可漏掉對故障有重大影響的元件。
第四步,對清單中所列出的元件按以往的經驗和元件檢查的難易排列次序。必要時,列出重點檢查的元件和元件的重點檢查部位。可同時利用儀器進行丈量。
第五步,對清單中列出的重點檢查元件進行初檢。初檢應判定以下一些題目:元件的用途和裝配是否合適;元件的丈量裝置、儀器和測試方法是否合適;元件的外部信號是否合適,對外部信號是否響應等。特別留意某些元件的故障先兆,如過高的溫度和噪聲、振動和泄漏等。
第六步,假如初檢中未查出故障,要用儀器反復檢查。
第七步,識別出發生故障的元件。對分歧格的元件進行修理或更換。
第八步,在重新啟動主機前,必需先當真考慮一下這次故障的原因和后果。假如故障是因為污染或油溫過高引起的,則應預料到其他元件也有泛起故障的可能性,同時對隱患采取相應的措施。例如,因為污染原因引起液壓泵的故障,則在更換新泵前必需對系統進行徹底清洗和過濾。
(2)重新啟動
排除液壓系統故障之后,不能操之過急,盲目啟動,必需遵照一定的要乞降程序啟動。否則,舊的故障排除了,新的故障會接踵產生。其主要原因是缺乏周密的思索。如前所述,液壓泵因為污染而泛起故障,那么,污染是怎樣引起的?其他液壓元件是否也被污染了呢?

Processing failure, according to the following steps.
( 1 ) Finding fault hydraulic 免費信息ponents
Hydraulic system failure the system is sometimes caused by a 免費信息ponent failure , therefore , a first need to find out the faulty 免費信息ponent . According to the following steps to check the hydraulic system can be generated to identify the failed 免費信息ponent .
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 免費信息ponents, 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 免費信息ponents 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 免費信息ponent based on past experience and the difficulty of checking 免費信息ponents arranged in order. If necessary, check the list of key elements and 免費信息ponents focus on examination area. While taking advantage of the instrument can measure .
The fifth step, focusing on the list, check the 免費信息ponents listed in the beginning of the seizure . Initial inspection should determine the following some of the topics : the use of 免費信息ponents and assemblies is appropriate ; 免費信息ponent measuring apparatus , instruments and testing methods are appropriate ; 免費信息ponents external signal is appropriate, whether the response to external signals and so on. Special attention to the failure of certain 免費信息ponents 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 免費信息ponent . Differences in cell 免費信息ponents 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 免費信息ponents 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 免費信息ponents also is polluted it ?
