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，作用是保證膠管的使(shi)用(yong)(yong)壓(ya)(ya)力。內膠(jiao)層具(ju)有使(shi)輸送介質(zhi)承受壓(ya)(ya)力，保護鋼(gang)絲(si)或線(xian)纖(xian)維不(bu)(bu)受侵蝕(shi)的作用(yong)(yong)。適宜于(yu)(yu)工(gong)程建筑(zhu)、起重運輸、冶金(jin)鍛(duan)壓(ya)(ya)、礦山設備(bei)、船舶、注(zhu)塑機械、農(nong)業機械、各(ge)種機床以(yi)及(ji)各(ge)工(gong)業部門機械化、自動化液(ye)(ye)壓(ya)(ya)系統中輸送具(ju)有一定(ding)壓(ya)(ya)力和(he)溫度的石油基及(ji)水基液(ye)(ye)體(ti)等(deng)和(he)液(ye)(ye)體(ti)傳動。按生產工(gong)藝分鋼(gang)絲(si)編織(zhi)膠(jiao)管(guan)(guan)、鋼(gang)絲(si)纏繞(rao)膠(jiao)管(guan)(guan)、線(xian)編織(zhi)膠(jiao)管(guan)(guan)和(he)夾(jia)布(bu)膠(jiao)管(guan)(guan)。膠(jiao)管(guan)(guan)使(shi)用(yong)(yong)注(zhu)意事項由于(yu)(yu)膠(jiao)管(guan)(guan)品種復雜，結構多樣，加之使(shi)用(yong)(yong)條件(jian)不(bu)(bu)一，因此膠(jiao)管(guan)(guan)使(shi)用(yong)(yong)壽(shou)命(ming)長短(duan)，不(bu)(bu)僅決定(ding)于(yu)(yu)質(zhi)量的好壞，同時也決定(ding)于(yu)(yu)正確使(shi)用(yong)(yong)保養。
