大連軟管總成主要(yao)用(yong)于礦井(jing)液(ye)(ye)壓(ya)(ya)(ya)(ya)支架(jia)、油(you)(you)田開采，適宜(yi)于工(gong)程建筑、起(qi)重運輸、冶(ye)金鍛壓(ya)(ya)(ya)(ya)、礦山設備、船舶、注塑機械、農業(ye)機械、各種機床(chuang)以(yi)及各工(gong)業(ye)部門機械化、自動(dong)(dong)化液(ye)(ye)壓(ya)(ya)(ya)(ya)系統中輸送具有(you)一定(ding)壓(ya)(ya)(ya)(ya)力(li)(li)和溫度的石油(you)(you)基，如(ru)礦物油(you)(you)、可(ke)(ke)溶性油(you)(you)、液(ye)(ye)壓(ya)(ya)(ya)(ya)油(you)(you)、燃油(you)(you)、潤滑油(you)(you)及水基液(ye)(ye)體(ti)，如(ru)乳化液(ye)(ye)、油(you)(you)水乳濁(zhuo)液(ye)(ye)、水等和液(ye)(ye)體(ti)傳動(dong)(dong)用(yong)，最高耐工(gong)作(zuo)壓(ya)(ya)(ya)(ya)力(li)(li)可(ke)(ke)達60MPa。軟(ruan)管規定(ding)的工(gong)作(zuo)壓(ya)(ya)(ya)(ya)力(li)(li)通常(chang)情況下(xia)不(bu)能(neng)小于最大系統壓(ya)(ya)(ya)(ya)力(li)(li),只有(you)在不(bu)常(chang)使(shi)(shi)用(yong)的情況下(xia),才允許提(ti)高20%；對(dui)于使(shi)(shi)用(yong)頻繁、經常(chang)彎(wan)扭者要(yao)降低40%。系統的沖擊壓(ya)(ya)(ya)(ya)力(li)(li)若高于軟(ruan)管規定(ding)的工(gong)作(zuo)壓(ya)(ya)(ya)(ya)力(li)(li)，不(bu)僅降低液(ye)(ye)壓(ya)(ya)(ya)(ya)軟(ruan)管使(shi)(shi)用(yong)壽命(ming)，且(qie)可(ke)(ke)能(neng)導(dao)致人身(shen)設備事故。這種氧(yang)化層極薄，透(tou)過它(ta)可(ke)(ke)以(yi)看到不(bu)銹鋼表面(mian)(mian)的自然光(guang)澤，使(shi)(shi)不(bu)銹鋼具有(you)獨特的表面(mian)(mian)。而(er)且(qie)，如(ru)果損壞(huai)了(le)表層，所暴(bao)露(lu)出的鋼表面(mian)(mian)會和大氣反應進(jin)行(xing)自我修(xiu)理，重新形成這種"鈍化膜(mo)"，繼(ji)續起(qi)保護作(zuo)用(yong)。
