力士樂液壓系統(tǒng)漏油會(huì)造成液壓量減少且不能建立正常油壓，從而導(dǎo)致系統(tǒng)不能正常工作。液壓系漏油有外漏和內(nèi)漏2種情況。外漏主要是油管破裂、接頭松動(dòng)、緊固不嚴(yán)密等情況等造成的；內(nèi)漏主要是液壓系統(tǒng)內(nèi)部的油泵、油缸、分配器等產(chǎn)生泄漏造成的。內(nèi)漏的故障不易被發(fā)現(xiàn)，有時(shí)還需借助儀器進(jìn)行檢測(cè)和調(diào)整，才能排除。

    1、 齒輪油泵相關(guān)部位嚴(yán)重磨損或裝配錯(cuò)誤

    （1）油泵齒輪與泵殼的配合間隙超過規(guī)定極限。處理方法是：更換泵殼或采用鑲套法修復(fù)，保證油泵齒輪齒頂與殼體配合間隙在規(guī)定范圍之內(nèi)。
 
    （2）齒輪軸套與齒輪端面過度磨損，使卸壓密封圈預(yù)壓縮量不足而失去密封作用，導(dǎo)致油泵高壓油腔與低壓油腔串通，內(nèi)漏嚴(yán)重。處理方法是：在后軸套下面加補(bǔ)償墊片（補(bǔ)償墊片厚度一般不宜超過2mm），保證密封圈安放的壓縮量。

    （3）拆裝油泵時(shí)，在2個(gè)軸套（螺旋油溝的軸套）結(jié)合面處，將導(dǎo)向鋼絲裝錯(cuò)方向。處理方法是：保證導(dǎo)向鋼絲能同時(shí)將2個(gè)軸套按被動(dòng)齒輪旋轉(zhuǎn)方向偏轉(zhuǎn)一個(gè)角度，使2個(gè)軸套平面貼合緊密。

    （4）在拆裝油泵時(shí)，隔壓密封圈老化損壞，卸壓片密封膠圈被裝錯(cuò)。處理方法是：若隔壓密封圈老化，應(yīng)更換新件：卸壓片密封膠圈應(yīng)裝在吸油腔（口）一側(cè)（低壓腔），并保證有一定的預(yù)緊壓力。如裝在壓油腔一側(cè)，密封膠圈會(huì)很快損壞，造成高壓腔與低壓腔相通，使油泵喪失工作能力。

    2、油缸密封圈老化和損壞活塞桿鎖緊螺母松動(dòng)

    （1）油缸活塞上的密封圈、活塞桿與活塞接合處的密封擋圈、定位閥密封圈損壞。處理方法是：更換密封圈和密封擋圈。但要注意，選用的密封圈表面應(yīng)光滑；無(wú)皺紋、無(wú)裂縫、無(wú)氣孔、無(wú)擦傷等。

    （2）活塞桿鎖緊螺母松動(dòng)。處理方法是：擰緊活塞桿鎖緊螺母。

    （3）缸筒失圓嚴(yán)重時(shí)，可能導(dǎo)致油缸上下腔的液壓油相通。處理方法：若失圓不太嚴(yán)重，可采取更換加大活塞密封圈的辦法來(lái)恢復(fù)其密封性；若圓度、圓柱度誤差超過0.05mm時(shí)，則應(yīng)對(duì)缸筒進(jìn)行珩磨加工，更換加大活塞，來(lái)恢復(fù)正常配合間隙。

    3、分配器上的安全閥和回油閥關(guān)閉不嚴(yán)

    （1）安全閥磨損或液壓油過臟；球閥銹蝕，調(diào)節(jié)彈簧彈力不足或折斷；液壓油不合規(guī)格；液壓油過稀或油溫過高（液壓油的正常溫度應(yīng)是30℃~60℃），都會(huì)使安全閥關(guān)閉不嚴(yán)。處理方法是：更換清潔的符合標(biāo)準(zhǔn)的液壓油；更換規(guī)定長(zhǎng)度和彈力的彈簧；更換球閥中的球，裝入閥座后可敲擊，使之與閥座貼合，并進(jìn)行研磨。

    （2）回油閥磨損嚴(yán)重或因液壓油過臟而導(dǎo)致回油閥關(guān)閉不嚴(yán)。處理方法是：研磨錐面及互研閥座。若圓柱面嚴(yán)重磨損，可采取鍍鉻磨削的方法修復(fù)；若小圓柱面與導(dǎo)管磨損，造成內(nèi)隙過大，可在導(dǎo)管內(nèi)鑲銅套，恢復(fù)配合間隙。清洗油缸，更換清潔的液壓油。

     滑閥與滑閥孔磨損，使間隙增大，油缸的油在活塞作用下從磨損的間隙處滲漏，流回油箱。處理方法是：鍍鉻后磨削修復(fù)，與滑閥孔選配。
