大連軟管總成主要用(yong)于礦(kuang)井(jing)液(ye)壓(ya)支(zhi)架(jia)、油(you)(you)(you)田開采，適宜于工(gong)(gong)程(cheng)建筑、起重(zhong)運輸、冶金鍛壓(ya)、礦(kuang)山設備、船舶、注塑(su)機(ji)械、農業機(ji)械、各(ge)種機(ji)床以及各(ge)工(gong)(gong)業部(bu)門機(ji)械化(hua)(hua)、自(zi)動化(hua)(hua)液(ye)壓(ya)系(xi)(xi)統(tong)中(zhong)輸送(song)具有一定(ding)壓(ya)力和溫度的(de)(de)石油(you)(you)(you)基，如(ru)(ru)礦(kuang)物油(you)(you)(you)、可(ke)溶性油(you)(you)(you)、液(ye)壓(ya)油(you)(you)(you)、燃油(you)(you)(you)、潤滑油(you)(you)(you)及水(shui)基液(ye)體(ti)，如(ru)(ru)乳化(hua)(hua)液(ye)、油(you)(you)(you)水(shui)乳濁液(ye)、水(shui)等和液(ye)體(ti)傳動用(yong)，最(zui)高(gao)(gao)耐(nai)工(gong)(gong)作(zuo)壓(ya)力可(ke)達60MPa。軟管(guan)規定(ding)的(de)(de)工(gong)(gong)作(zuo)壓(ya)力通常情(qing)況下(xia)不(bu)(bu)(bu)能小于最(zui)大系(xi)(xi)統(tong)壓(ya)力,只(zhi)有在不(bu)(bu)(bu)常使用(yong)的(de)(de)情(qing)況下(xia),才允許提高(gao)(gao)20%；對于使用(yong)頻繁、經常彎(wan)扭者要降(jiang)低(di)40%。系(xi)(xi)統(tong)的(de)(de)沖(chong)擊壓(ya)力若(ruo)高(gao)(gao)于軟管(guan)規定(ding)的(de)(de)工(gong)(gong)作(zuo)壓(ya)力，不(bu)(bu)(bu)僅降(jiang)低(di)液(ye)壓(ya)軟管(guan)使用(yong)壽命(ming)，且(qie)可(ke)能導致人(ren)身設備事故。這種氧化(hua)(hua)層極薄，透過它可(ke)以看到(dao)不(bu)(bu)(bu)銹鋼表(biao)面(mian)的(de)(de)自(zi)然光澤，使不(bu)(bu)(bu)銹鋼具有獨特的(de)(de)表(biao)面(mian)。而且(qie)，如(ru)(ru)果損壞了表(biao)層，所暴露出(chu)的(de)(de)鋼表(biao)面(mian)會(hui)和大氣反應進行自(zi)我修(xiu)理，重(zhong)新形成這種"鈍(dun)化(hua)(hua)膜"，繼續起保護作(zuo)用(yong)。
