   對機(ji)(ji)械化施工(gong)(gong)企業來(lai)說，工(gong)(gong)程機(ji)(ji)械技(ji)術狀(zhuang)況的(de)良好與否是(shi)(shi)企業能否正常生產的(de)直接(jie)因素。就液(ye)壓(ya)傳(chuan)動的(de)工(gong)(gong)程機(ji)(ji)械而言，液(ye)壓(ya)系(xi)(xi)統(tong)的(de)正常運(yun)行是(shi)(shi)其良好技(ji)術狀(zhuang)況的(de)一(yi)個主要標志。合格(ge)的(de)液(ye)壓(ya)油是(shi)(shi)液(ye)壓(ya)系(xi)(xi)統(tong)可靠(kao)運(yun)行的(de)保障，正確的(de)維護是(shi)(shi)液(ye)壓(ya)系(xi)(xi)統(tong)可靠(kao)運(yun)行的(de)根本。為(wei)此，本人根據工(gong)(gong)作實踐(jian)，就一(yi)般作業環境(jing)中工(gong)(gong)程機(ji)(ji)械液(ye)壓(ya)系(xi)(xi)統(tong)的(de)維護作一(yi)粗(cu)略的(de)探(tan)討。

　　選擇適(shi)合的液壓油

　　液(ye)(ye)(ye)(ye)壓(ya)(ya)油(you)(you)在液(ye)(ye)(ye)(ye)壓(ya)(ya)系統中(zhong)起著傳(chuan)遞壓(ya)(ya)力、潤滑、冷卻、密封的(de)作用，液(ye)(ye)(ye)(ye)壓(ya)(ya)油(you)(you)選擇(ze)不恰當是液(ye)(ye)(ye)(ye)壓(ya)(ya)系統早期(qi)故障和耐久(jiu)性(xing)下(xia)降的(de)主要(yao)原(yuan)(yuan)因。應按隨機《使用說明書》中(zhong)規定的(de)牌號選擇(ze)液(ye)(ye)(ye)(ye)壓(ya)(ya)油(you)(you)，特殊情(qing)況需要(yao)使用代(dai)用油(you)(you)時，應力求其(qi)性(xing)能(neng)與原(yuan)(yuan)牌號性(xing)能(neng)相同(tong)。不同(tong)牌號的(de)液(ye)(ye)(ye)(ye)壓(ya)(ya)油(you)(you)不能(neng)混合使用，以防液(ye)(ye)(ye)(ye)壓(ya)(ya)油(you)(you)產生(sheng)化學(xue)反應、性(xing)能(neng)發生(sheng)變化。深褐色、乳白色、有異(yi)味的(de)液(ye)(ye)(ye)(ye)壓(ya)(ya)油(you)(you)是變質(zhi)油(you)(you)，不能(neng)使用。

液(ye)(ye)(ye)壓(ya)(ya)(ya)站又稱(cheng)為液(ye)(ye)(ye)壓(ya)(ya)(ya)泵(beng)站，系統(tong)(tong)元件主要是(shi)(shi)由液(ye)(ye)(ye)壓(ya)(ya)(ya)泵(beng)、液(ye)(ye)(ye)壓(ya)(ya)(ya)缸、液(ye)(ye)(ye)壓(ya)(ya)(ya)馬達、液(ye)(ye)(ye)壓(ya)(ya)(ya)閥(fa)等構成(cheng)的。液(ye)(ye)(ye)壓(ya)(ya)(ya)泵(beng)是(shi)(shi)液(ye)(ye)(ye)壓(ya)(ya)(ya)系統(tong)(tong)的心臟，簡稱(cheng)油(you)泵(beng)。在(zai)液(ye)(ye)(ye)壓(ya)(ya)(ya)系統(tong)(tong)中，一(yi)定至少有一(yi)個泵(beng)。液(ye)(ye)(ye)壓(ya)(ya)(ya)泵(beng)是(shi)(shi)一(yi)種能(neng)(neng)量(liang)轉換裝置，它(ta)的作用是(shi)(shi)使(shi)液(ye)(ye)(ye)體發生運動，把機械能(neng)(neng)轉換成(cheng)流(liu)體能(neng)(neng)（也叫(jiao)做(zuo)液(ye)(ye)(ye)壓(ya)(ya)(ya)能(neng)(neng)）。液(ye)(ye)(ye)壓(ya)(ya)(ya)系統(tong)(tong)

泵(beng)是(shi)液(ye)(ye)壓(ya)(ya)傳(chuan)動(dong)系(xi)統中(zhong)(zhong)的(de)動(dong)力(li)元件，由原動(dong)機驅動(dong)，從原動(dong)機的(de)輸(shu)出功率中(zhong)(zhong)取出機械能，為系(xi)統提供壓(ya)(ya)力(li)油(you)液(ye)(ye)。然后，在需要做功的(de)場所(suo)，由執行(xing)元件（液(ye)(ye)壓(ya)(ya)缸或液(ye)(ye)壓(ya)(ya)馬達）再把流體壓(ya)(ya)力(li)能轉換(huan)成機械能輸(shu)出。

液(ye)壓(ya)(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)在(zai)液(ye)壓(ya)(ya)(ya)(ya)(ya)系(xi)(xi)統(tong)中(zhong)的(de)工(gong)作(zuo)方(fang)式(shi)是閥(fa)(fa)(fa)體和閥(fa)(fa)(fa)芯(xin)(xin)相(xiang)對(dui)運(yun)動(dong)，這種工(gong)作(zuo)方(fang)式(shi)不(bu)(bu)(bu)可避免的(de)就是磨損。液(ye)壓(ya)(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)的(de)閥(fa)(fa)(fa)體和閥(fa)(fa)(fa)芯(xin)(xin)進行相(xiang)對(dui)運(yun)動(dong)的(de)過程(cheng)中(zhong)，會不(bu)(bu)(bu)斷的(de)摩擦，在(zai)工(gong)作(zuo)一段時間后，液(ye)壓(ya)(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)各(ge)元件之間的(de)尺寸、形狀、質量(liang)等發(fa)生(sheng)變化(hua)，不(bu)(bu)(bu)再是液(ye)壓(ya)(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)原(yuan)有(you)的(de)特性，在(zai)液(ye)壓(ya)(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)工(gong)作(zuo)中(zhong)就會失效，出現故障(zhang)。例如(ru)，在(zai)液(ye)壓(ya)(ya)(ya)(ya)(ya)系(xi)(xi)統(tong)中(zhong)的(de)減壓(ya)(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)工(gong)作(zuo)中(zhong)，錐閥(fa)(fa)(fa)和閥(fa)(fa)(fa)座(zuo)之間因為長(chang)時間的(de)摩擦、磨損，造(zao)成零件之間的(de)配合度不(bu)(bu)(bu)好，在(zai)液(ye)壓(ya)(ya)(ya)(ya)(ya)系(xi)(xi)統(tong)中(zhong)，減壓(ya)(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)就無法起(qi)到減壓(ya)(ya)(ya)(ya)(ya)的(de)作(zuo)用(yong)。
