防止污染物進入液壓系統的解決方案

      污(wu)染度檢(jian)測(ce)系統油(you)箱要合(he)理(li)密封并裝(zhuang)設能的空(kong)氣濾清器以防(fang)止(zhi)塵土(tu)、水(shui)分(fen)的進入(ru);注入(ru)新油(you)必須經過有效的過濾，系統的回油(you)也應進行有效的過濾;管(guan)路接頭(tou)等連接處密封嚴密，防(fang)止(zhi)塵土(tu)、水(shui)分(fen)和空(kong)氣進入(ru)液(ye)壓系統;活動件(如液(ye)壓缸活塞桿(gan)端)必須裝(zhuang)有防(fang)塵密封裝(zhuang)置。

　　1液(ye)壓油(you)的過濾和凈(jing)化(hua)

　　污(wu)染(ran)度(du)檢(jian)測系(xi)(xi)(xi)統(tong)(tong)液壓油(you)(you)(you)(you)過(guo)(guo)(guo)濾(lv)(lv)(lv)器(qi)(qi)(qi)(qi)(濾(lv)(lv)(lv)油(you)(you)(you)(you)器(qi)(qi)(qi)(qi))是(shi)液壓系(xi)(xi)(xi)統(tong)(tong)中控(kong)制油(you)(you)(you)(you)液污(wu)染(ran)的(de)(de)(de)重要(yao)(yao)元(yuan)件，濾(lv)(lv)(lv)油(you)(you)(you)(you)器(qi)(qi)(qi)(qi)的(de)(de)(de)應(ying)用必須保證過(guo)(guo)(guo)濾(lv)(lv)(lv)精度(du)符合系(xi)(xi)(xi)統(tong)(tong)的(de)(de)(de)使(shi)用要(yao)(yao)求，由流體阻力引起的(de)(de)(de)壓力損(sun)失應(ying)盡能小(xiao)，并(bing)應(ying)具有足夠(gou)的(de)(de)(de)油(you)(you)(you)(you)垢容(rong)量;時對(dui)濾(lv)(lv)(lv)油(you)(you)(you)(you)器(qi)(qi)(qi)(qi)進行檢(jian)查(cha)和凈化。液壓系(xi)(xi)(xi)統(tong)(tong)油(you)(you)(you)(you)液的(de)(de)(de)污(wu)染(ran)度(du)隨(sui)著(zhu)(zhu)外(wai)界(jie)污(wu)染(ran)顆粒侵入率和系(xi)(xi)(xi)統(tong)(tong)內各(ge)種磨損(sun)顆粒數(shu)的(de)(de)(de)增(zeng)加而(er)增(zeng)大，隨(sui)著(zhu)(zhu)過(guo)(guo)(guo)濾(lv)(lv)(lv)比的(de)(de)(de)增(zeng)大而(er)減小(xiao)，因此合理選(xuan)擇過(guo)(guo)(guo)濾(lv)(lv)(lv)比有效(xiao)地降低(di)系(xi)(xi)(xi)統(tong)(tong)的(de)(de)(de)污(wu)染(ran)度(du)。固體顆粒是(shi)工程機械液壓系(xi)(xi)(xi)統(tong)(tong)污(wu)染(ran)的(de)(de)(de)主(zhu)要(yao)(yao)來源，通過(guo)(guo)(guo)合理選(xuan)擇濾(lv)(lv)(lv)油(you)(you)(you)(you)器(qi)(qi)(qi)(qi)的(de)(de)(de)過(guo)(guo)(guo)濾(lv)(lv)(lv)比是(shi)控(kong)制系(xi)(xi)(xi)統(tong)(tong)污(wu)染(ran)的(de)(de)(de)主(zhu)要(yao)(yao)措施。

　　2 期檢查和更換液壓(ya)油(you)

　　液壓(ya)(ya)(ya)油(you)(you)在使用過程中，污染(ran)物的侵入會對(dui)液壓(ya)(ya)(ya)系統造成不良的影響，要對(dui)液壓(ya)(ya)(ya)油(you)(you)污染(ran)進行有效的控制，必須期對(dui)各密封(feng)處、接(jie)頭(tou)處進行檢查處理，對(dui)液壓(ya)(ya)(ya)系統的液壓(ya)(ya)(ya)油(you)(you)進行檢查分析，還要期更換液壓(ya)(ya)(ya)油(you)(you)。更換液壓(ya)(ya)(ya)油(you)(you)時(shi)必須將舊液壓(ya)(ya)(ya)油(you)(you)放凈，整個液壓(ya)(ya)(ya)系統必須先清潔后(hou)，再注(zhu)入新的液壓(ya)(ya)(ya)油(you)(you)。

　　3采用液(ye)壓(ya)油(you)污染度檢(jian)測(ce)儀(yi)的在線監測(ce)技術

　　在(zai)(zai)作業(ye)上(shang)采用液(ye)(ye)壓(ya)(ya)油污染(ran)(ran)度(du)在(zai)(zai)線污染(ran)(ran)度(du)檢(jian)測(ce)系統檢(jian)測(ce)，隨時(shi)監測(ce)液(ye)(ye)壓(ya)(ya)油在(zai)(zai)使用過程中(zhong)(zhong)的品(pin)質(zhi)，而且能(neng)及時(shi)準確(que)地通過顯(xian)示(shi)器顯(xian)示(shi)污染(ran)(ran)等級及相應(ying)的原因，即使在(zai)(zai)工作人員沒有觀測(ce)到(dao)顯(xian)示(shi)器顯(xian)示(shi)的情況，當污染(ran)(ran)度(du)達(da)到(dao)相應(ying)的級別時(shi)，報(bao)警裝置(zhi)也會進行分(fen)級報(bao)警，以(yi)確(que)保工程機械在(zai)(zai)使用中(zhong)(zhong)液(ye)(ye)壓(ya)(ya)油性(xing)能(neng)及品(pin)質(zhi)的良好性(xing)。
