style="text-indent:25px">由液壓系統(tǒng)的工作原理可知，在系統(tǒng)中產(chǎn)生熱量的有兩部份：一個(gè)是將機(jī)械能轉(zhuǎn)化為壓力能的動(dòng)力元件油泵，另一個(gè)是將壓力能轉(zhuǎn)化為機(jī)械能的控制元件和執(zhí)行元件；這兩部份在正常工作狀態(tài)下都要產(chǎn)生熱量，這些熱量由系統(tǒng)的冷卻系統(tǒng)進(jìn)行冷卻。一般流量較大的液壓系統(tǒng)均裝有冷卻系統(tǒng)，大部分會(huì)采用水冷卻。它的基本原理是用溫度較低的水與高溫液壓油進(jìn)行熱交換，來不斷帶走液壓系統(tǒng)中產(chǎn)生的熱量，使液壓系統(tǒng)的溫度保持在一個(gè)相對(duì)恒定的范圍內(nèi)。冷卻水不通或入口水溫比系統(tǒng)油溫高達(dá)不到與液壓油形成熱交換的作用。冷卻器(熱交換器)內(nèi)部結(jié)垢，導(dǎo)致冷卻效率降低，使液壓油油溫不能維持在正常水平。</p><p style="text-indent:25px"> 拆卸前，應(yīng)將液壓油排放干凈，弄清液壓回路內(nèi)是否有強(qiáng)余的壓力，拆卸裝有蓄能器的液壓系統(tǒng)時(shí)，必須把蓄能器所有能量全部釋放，在拆卸挖掘機(jī)、裝載機(jī)和推土機(jī)等液壓系統(tǒng)時(shí)，必須將挖斗或鏟斗放到地面或用支柱支好，拆卸時(shí)不能亂敲亂打，以防損壞螺紋和密封表面，在拆卸缸時(shí)，不應(yīng)將活塞硬性從缸筒中打出，以免損壞表面，正確的方法是拆卸前依靠液壓油壓力使活塞移到缸筒的末端，然后進(jìn)行拆卸，拆下的零件的螺紋部分和密封面都要用膠布纏好，以防碰傷拆下的小零件要分別裝入塑料袋中保存；沒有必要，不要將多聯(lián)閥體拆成單體，拆卸油管時(shí)，要及時(shí)做好標(biāo)簽，以防裝錯(cuò)，拆下的油管要用清洗設(shè)備將管內(nèi)沖洗干凈，在兩端堵上塑料塞，拆下的油泵、油、馬達(dá)和閥的孔口，也要用塑料塞塞好或用膠布粘蓋好。液壓系統(tǒng)由信號(hào)控制和液壓動(dòng)力兩部分組成。</p><div
