大連膠管使用壽命長短，不僅決定于質量的好壞，同時也決定于正確使用保養。外膠層保護增強層不受損傷，增強層是骨架材料，作用是保證膠管的(de)(de)使(shi)(shi)(shi)用(yong)(yong)壓(ya)(ya)(ya)力。內膠(jiao)層(ceng)具有使(shi)(shi)(shi)輸送介質(zhi)承(cheng)受壓(ya)(ya)(ya)力，保(bao)護鋼(gang)(gang)絲(si)或線纖(xian)維(wei)不(bu)受侵蝕的(de)(de)作用(yong)(yong)。適宜于工(gong)程建筑(zhu)、起重運輸、冶金鍛(duan)壓(ya)(ya)(ya)、礦山設備(bei)、船舶、注(zhu)(zhu)塑機(ji)(ji)械(xie)、農(nong)業機(ji)(ji)械(xie)、各種(zhong)機(ji)(ji)床以及各工(gong)業部(bu)門機(ji)(ji)械(xie)化、自(zi)動化液壓(ya)(ya)(ya)系統中輸送具有一定(ding)壓(ya)(ya)(ya)力和(he)(he)溫度(du)的(de)(de)石油基(ji)及水基(ji)液體等(deng)和(he)(he)液體傳動。按(an)生(sheng)產(chan)工(gong)藝分鋼(gang)(gang)絲(si)編織(zhi)膠(jiao)管(guan)、鋼(gang)(gang)絲(si)纏繞膠(jiao)管(guan)、線編織(zhi)膠(jiao)管(guan)和(he)(he)夾布膠(jiao)管(guan)。膠(jiao)管(guan)使(shi)(shi)(shi)用(yong)(yong)注(zhu)(zhu)意事(shi)項由于膠(jiao)管(guan)品種(zhong)復雜，結構多(duo)樣，加之使(shi)(shi)(shi)用(yong)(yong)條件(jian)不(bu)一，因此(ci)膠(jiao)管(guan)使(shi)(shi)(shi)用(yong)(yong)壽命長短，不(bu)僅決定(ding)于質(zhi)量的(de)(de)好(hao)壞(huai)，同(tong)時也決定(ding)于正(zheng)確使(shi)(shi)(shi)用(yong)(yong)保(bao)養。
