液壓系統(tǒng)是液壓升降貨梯的動(dòng)力驅(qū)動(dòng)機(jī)構(gòu),液壓升降貨梯的液壓系統(tǒng)一旦出現(xiàn)故障,液壓升降貨梯連最基本的啟動(dòng)都無(wú)法做到,因此,我們要在日常使用液壓升降貨梯時(shí),注重對(duì)其液壓系統(tǒng)的定期保養(yǎng)。
   
1、液壓油一旦出現(xiàn)變暗、發(fā)粘或有砂礫等異物時(shí),應(yīng)及時(shí)更換，檢查滾輪、中間軸及軸承,油缸銷軸及軸承,臂架鉸軸及軸承等有無(wú)磨損,如有磨損應(yīng)立即進(jìn)行維修或更換。
Once the hydraulic oil darken, sticky or gravel and other foreign matter, should be replaced, check the wheel, intermediate shaft and bearings, cylinder pin and bearing, boom hinge shaft and bearings for wear, if worn should immediately for repair or replacement.   
2、各部位應(yīng)分別加注一些潤(rùn)滑油,這樣可以延長(zhǎng)軸承的使用壽命，把液壓油放盡棄掉,換上新油,避免繼續(xù)使用舊油.否則系統(tǒng)中的運(yùn)動(dòng)部件就會(huì)加速磨損。
Each part separately should raise some oil, so you can extend bearing life, the hydraulic oil exhausted discarded and replaced with new oil to avoid continued use of old oil, otherwise the system will be accelerated wear of moving parts.  
3、檢查所有的液壓管道和接頭,管道不得破損,接頭不得松動(dòng),必須將所有接頭擰緊，卸下并拆開(kāi)下降閥,用壓縮空氣將柱塞吹凈,然后裝入重新安裝。
Check all hydraulic pipes and fittings, pipes shall not damaged, loose joints shall be tightened all the joints, remove and open the lowering valve, the plunger blowing with compressed air, then into reinstalled.
