大連軟管總成主要用(yong)(yong)于礦(kuang)井液(ye)(ye)(ye)(ye)壓(ya)支架、油田開采，適(shi)宜于工(gong)(gong)程建筑(zhu)、起重運輸、冶金鍛壓(ya)、礦(kuang)山設備、船舶、注塑機(ji)械(xie)、農業機(ji)械(xie)、各種(zhong)(zhong)機(ji)床以(yi)及(ji)各工(gong)(gong)業部門機(ji)械(xie)化(hua)(hua)(hua)、自(zi)動化(hua)(hua)(hua)液(ye)(ye)(ye)(ye)壓(ya)系統中輸送具有一定(ding)壓(ya)力(li)和溫度的(de)石油基(ji)，如(ru)礦(kuang)物油、可(ke)溶性油、液(ye)(ye)(ye)(ye)壓(ya)油、燃油、潤滑油及(ji)水基(ji)液(ye)(ye)(ye)(ye)體，如(ru)乳化(hua)(hua)(hua)液(ye)(ye)(ye)(ye)、油水乳濁(zhuo)液(ye)(ye)(ye)(ye)、水等和液(ye)(ye)(ye)(ye)體傳動用(yong)(yong)，最高(gao)耐(nai)工(gong)(gong)作(zuo)壓(ya)力(li)可(ke)達60MPa。軟管規(gui)定(ding)的(de)工(gong)(gong)作(zuo)壓(ya)力(li)通常情(qing)況下不(bu)能(neng)小于最大(da)系統壓(ya)力(li),只有在不(bu)常使用(yong)(yong)的(de)情(qing)況下,才(cai)允許提(ti)高(gao)20%；對于使用(yong)(yong)頻繁、經常彎(wan)扭(niu)者要降低(di)40%。系統的(de)沖擊壓(ya)力(li)若高(gao)于軟管規(gui)定(ding)的(de)工(gong)(gong)作(zuo)壓(ya)力(li)，不(bu)僅(jin)降低(di)液(ye)(ye)(ye)(ye)壓(ya)軟管使用(yong)(yong)壽(shou)命，且可(ke)能(neng)導致人身(shen)設備事(shi)故。這種(zhong)(zhong)氧化(hua)(hua)(hua)層(ceng)極(ji)薄(bo)，透過它可(ke)以(yi)看到不(bu)銹鋼表(biao)面(mian)的(de)自(zi)然光澤，使不(bu)銹鋼具有獨特的(de)表(biao)面(mian)。而且，如(ru)果損壞了表(biao)層(ceng)，所暴(bao)露出的(de)鋼表(biao)面(mian)會和大(da)氣反(fan)應進行自(zi)我修(xiu)理，重新形(xing)成這種(zhong)(zhong)"鈍化(hua)(hua)(hua)膜"，繼續起保護作(zuo)用(yong)(yong)。
