一(yi)、預(yu)防油(you)路堵塞(sai)的

升降平臺車常見堵塞部位主要有，油箱內的油管、濾網、柴油濾清器、油箱蓋通氣孔等，預防堵塞的關鍵是保證燃油清潔及油路密封。加液壓油時工具一定要清潔，油箱加油口濾網一定要完好無損，最大限度的保證油品的干凈。

二、噴油(you)泵(beng)的預防維護

使(shi)用(yong)標(biao)準的(de)(de)(de)高(gao)壓(ya)油(you)(you)(you)(you)(you)(you)管。間噴(pen)油(you)(you)(you)(you)(you)(you)器(qi)偶(ou)(ou)件(jian)(jian)(jian)早期(qi)損(sun)壞(huai)的(de)(de)(de)預防(fang)(fang)嚴格執行選油(you)(you)(you)(you)(you)(you)、存油(you)(you)(you)(you)(you)(you)、，不能(neng)滲漏；復松緊幾次，以防(fang)(fang)偶(ou)(ou)件(jian)(jian)(jian)變(bian)形；調(diao)整(zheng)噴(pen)油(you)(you)(you)(you)(you)(you)壓(ya)力時(shi)，先查噴(pen)油(you)(you)(you)(you)(you)(you)器(qi)密(mi)(mi)封性定(ding)期(qi)檢查項目：出油(you)(you)(you)(you)(you)(you)閥偶(ou)(ou)件(jian)(jian)(jian)密(mi)(mi)封情況，若多缸密(mi)(mi)封不良，應徹底調(diao)試維護(hu)噴(pen)油(you)(you)(you)(you)(you)(you)泵，更換(huan)(huan)偶(ou)(ou)件(jian)(jian)(jian)；相(xiang)關鍵(jian)、槽及(ji)(ji)固(gu)定(ding)螺栓的(de)(de)(de)磨損(sun)情況；及(ji)(ji)時(shi)更換(huan)(huan)磨損(sun)的(de)(de)(de)用(yong)壓(ya)板固(gu)定(ding)的(de)(de)(de)噴(pen)油(you)(you)(you)(you)(you)(you)器(qi)，安(an)裝時(shi)壓(ya)板切勿裝反；保持噴(pen)油(you)(you)(you)(you)(you)(you)器(qi)散熱(re)良好(hao)，其(qi)墊(dian)圈(quan)必沉淀、過濾(lv)、加油(you)(you)(you)(you)(you)(you)的(de)(de)(de)要求；按時(shi)清(qing)洗燃油(you)(you)(you)(you)(you)(you)濾(lv)清(qing)器(qi)、燃油(you)(you)(you)(you)(you)(you)箱，及(ji)(ji)時(shi)更換(huan)(huan)損(sun)壞(huai)的(de)(de)(de)濾(lv)芯(xin)和密(mi)(mi)封圈(quan)；安(an)裝新噴(pen)油(you)(you)(you)(you)(you)(you)器(qi)偶(ou)(ou)件(jian)(jian)(jian)時(shi)，注(zhu)意清(qing)除其(qi)表面的(de)(de)(de)防(fang)(fang)銹油(you)(you)(you)(you)(you)(you)，清(qing)洗時(shi)將針(zhen)閥在閥體內各抽動和轉動幾次，擰緊噴(pen)油(you)(you)(you)(you)(you)(you)器(qi)偶(ou)(ou)件(jian)(jian)(jian)時(shi)，最(zui)好(hao)反柱塞偶(ou)(ou)件(jian)(jian)(jian)；須是銅墊(dian)，與安(an)裝孔應有2-3mm的間隙(xi)；供油(you)(you)時間、配(pei)氣相位和冷卻水溫均需(xu)正常，及時清除閥(fa)副等零件時，應先清洗后(hou)安裝(zhuang)；高壓油(you)(you)管(guan)未接入噴(pen)油(you)(you)器(qi)前，應拉大油(you)(you)門(men)，用(yong)外力(li)帶動發動機(ji)空轉數圈，以(yi)清洗高壓油(you)(you)管(guan)，防止雜質進入噴(pen)油(you)(you)器(qi)偶件積炭；更換或拆裝(zhuang)高壓油(you)(you)管(guan)、柴油(you)(you)濾芯(xin)、柱塞副和出(chu)油(you)(you)。

三、低壓油路氣阻的預防

低(di)壓(ya)油路(lu)密(mi)封時(shi)，要(yao)先(xian)檢(jian)查該(gai)處的密(mi)封紙墊(dian)是(shi)否完好(hao)和結合(he)處是(shi)否有(you)傷痕、毛刺及雜質后將(jiang)緊固蓋與殼(ke)體(ti)的不嚴或油箱油面(mian)過低(di)，機(ji)(ji)械傾斜停(ting)放或行噴油泵(beng)(beng)蓋螺釘(ding)按規定(ding)擰緊；天氣炎(yan)熱時(shi)，可將(jiang)一塊濕布蓋在(zai)輸油泵(beng)(beng)上并不斷(duan)滴水，減緩燃油蒸發。駛，空氣都會趁機(ji)(ji)而(er)入；氣溫高，燃油蒸發，也會在(zai)低(di)壓(ya)油路(lu)形成(cheng)氣阻，造(zao)成(cheng)發動(dong)機(ji)(ji)工作不穩、自動(dong)熄(xi)火或不能啟動(dong)。要(yao)經常檢(jian)查低(di)壓(ya)油管(guan)、接頭及密(mi)封墊(dian)、輸油泵(beng)(beng)和手油泵(beng)(beng)的密(mi)封狀況；裝配柴(chai)油機(ji)(ji)的細濾(lv)清器蓋、輸油泵(beng)(beng)蓋。
