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)使(shi)(shi)用(yong)壓(ya)力。內膠(jiao)(jiao)層具有(you)使(shi)(shi)輸送(song)介質(zhi)承受壓(ya)力，保(bao)護(hu)鋼(gang)絲或(huo)線纖維不(bu)受侵蝕的(de)作用(yong)。適宜于工(gong)程建(jian)筑、起重(zhong)運輸、冶(ye)金鍛(duan)壓(ya)、礦山設備、船舶、注塑機(ji)械、農(nong)業機(ji)械、各種機(ji)床以(yi)及(ji)各工(gong)業部門機(ji)械化、自動化液(ye)壓(ya)系統中輸送(song)具有(you)一(yi)定(ding)壓(ya)力和溫度的(de)石(shi)油(you)基及(ji)水(shui)基液(ye)體等和液(ye)體傳動。按生產工(gong)藝分鋼(gang)絲編織膠(jiao)(jiao)管(guan)(guan)(guan)、鋼(gang)絲纏繞(rao)膠(jiao)(jiao)管(guan)(guan)(guan)、線編織膠(jiao)(jiao)管(guan)(guan)(guan)和夾布膠(jiao)(jiao)管(guan)(guan)(guan)。膠(jiao)(jiao)管(guan)(guan)(guan)使(shi)(shi)用(yong)注意(yi)事項由于膠(jiao)(jiao)管(guan)(guan)(guan)品種復(fu)雜(za)，結構多(duo)樣，加之使(shi)(shi)用(yong)條件不(bu)一(yi)，因此膠(jiao)(jiao)管(guan)(guan)(guan)使(shi)(shi)用(yong)壽命(ming)長短，不(bu)僅(jin)決定(ding)于質(zhi)量的(de)好壞，同(tong)時(shi)也決定(ding)于正確使(shi)(shi)用(yong)保(bao)養(yang)。
