1、換油(you)(you)(you)前(qian)液(ye)(ye)(ye)(ye)(ye)壓(ya)(ya)系(xi)統要(yao)(yao)(yao)清(qing)洗(xi)。液(ye)(ye)(ye)(ye)(ye)壓(ya)(ya)系(xi)統每次使(shi)用(yong)液(ye)(ye)(ye)(ye)(ye)壓(ya)(ya)油(you)(you)(you)前(qian)，必須(xu)清(qing)洗(xi)干凈；在更(geng)換同(tong)一品(pin)種(zhong)液(ye)(ye)(ye)(ye)(ye)壓(ya)(ya)油(you)(you)(you)時(shi)，也要(yao)(yao)(yao)用(yong)新換的(de)液(ye)(ye)(ye)(ye)(ye)壓(ya)(ya)油(you)(you)(you)沖洗(xi)1-2次。2、液(ye)(ye)(ye)(ye)(ye)壓(ya)(ya)油(you)(you)(you)不能隨(sui)意(yi)混(hun)用(yong)。一種(zhong)牌(pai)號的(de)液(ye)(ye)(ye)(ye)(ye)壓(ya)(ya)油(you)(you)(you)，未經設備(bei)生產廠(chang)家同(tong)意(yi)和沒(mei)有科學(xue)依(yi)據時(shi)不能隨(sui)意(yi)與不同(tong)牌(pai)號的(de)液(ye)(ye)(ye)(ye)(ye)壓(ya)(ya)油(you)(you)(you)混(hun)用(yong)，更(geng)不得(de)與其他品(pin)種(zhong)的(de)液(ye)(ye)(ye)(ye)(ye)壓(ya)(ya)油(you)(you)(you)混(hun)用(yong)。3、注意(yi)液(ye)(ye)(ye)(ye)(ye)壓(ya)(ya)系(xi)統密(mi)封(feng)的(de)良好。液(ye)(ye)(ye)(ye)(ye)壓(ya)(ya)系(xi)統必須(xu)保(bao)持嚴格的(de)密(mi)封(feng)，防止泄漏(lou)和外界各種(zhong)塵(chen)土雜物和水(shui)等混(hun)入。4、加入新油(you)(you)(you)時(shi)，合肥液(ye)(ye)(ye)(ye)(ye)壓(ya)(ya)油(you)(you)(you)，必須(xu)按要(yao)(yao)(yao)求過濾。5、根據換油(you)(you)(you)指標及時(shi)更(geng)換液(ye)(ye)(ye)(ye)(ye)壓(ya)(ya)油(you)(you)(you)。

液壓(ya)(ya)(ya)(ya)(ya)(ya)油(you)油(you)溫異常升高的(de)根本原因有以下3個(ge)方面：一是(shi)由(you)于安(an)全閥壓(ya)(ya)(ya)(ya)(ya)(ya)力設(she)定值太低，使液壓(ya)(ya)(ya)(ya)(ya)(ya)油(you)大部分通過(guo)安(an)全閥流回油(you)箱(xiang)，致(zhi)使液壓(ya)(ya)(ya)(ya)(ya)(ya)系(xi)統做(zuo)功效率(lv)太低，如負荷(he)過(guo)大，低溫抗磨液壓(ya)(ya)(ya)(ya)(ya)(ya)油(you)，大部分能(neng)量會(hui)轉(zhuan)換成液壓(ya)(ya)(ya)(ya)(ya)(ya)油(you)的(de)熱能(neng)，導致(zhi)溫度很高。二是(shi)由(you)于冷卻系(xi)的(de)冷卻效果差，導致(zhi)液壓(ya)(ya)(ya)(ya)(ya)(ya)油(you)溫度過(guo)高。三是(shi)液壓(ya)(ya)(ya)(ya)(ya)(ya)油(you)在油(you)路中(zhong)循環(huan)過(guo)于頻(pin)繁(往往是(shi)油(you)量不足造(zao)成)，液壓(ya)(ya)(ya)(ya)(ya)(ya)油(you)廠(chang)家，導致(zhi)散熱困難，液壓(ya)(ya)(ya)(ya)(ya)(ya)油(you)批發，溫度升高。

液(ye)壓(ya)(ya)油(you)的(de)(de)使用(yong)和維護需要(yao)注(zhu)意哪些要(yao)點：1、液(ye)壓(ya)(ya)油(you)的(de)(de)清(qing)(qing)潔(jie)(jie)度正確的(de)(de)用(yong)油(you)方法對于(yu)液(ye)壓(ya)(ya)油(you)的(de)(de)性能意義重大。比起很(hen)多工(gong)業設備，液(ye)壓(ya)(ya)設備對油(you)的(de)(de)清(qing)(qing)潔(jie)(jie)度要(yao)求(qiu)很(hen)高。在使用(yong)過程中防止(zhi)液(ye)壓(ya)(ya)油(you)帶入(ru)雜質，注(zhu)意防塵(chen)、過濾。2、防高溫(wen)(wen)高溫(wen)(wen)加速(su)液(ye)壓(ya)(ya)油(you)的(de)(de)氧化(hua)，另外(wai)對膠管、密(mi)封等(deng)部(bu)件也不利，因此要(yao)避免液(ye)壓(ya)(ya)油(you)靠近熱源、使用(yong)中監測系統溫(wen)(wen)度。3、防水(shui)、防氣泡液(ye)壓(ya)(ya)油(you)里進水(shui)會導(dao)致油(you)變質、滋(zi)生細1菌。氣泡會引(yin)起液(ye)壓(ya)(ya)油(you)局(ju)部(bu)高溫(wen)(wen)，造(zao)成氧化(hua)。
