膠管內(nei)徑(jing)要適(shi)當。管(guan)(guan)徑(jing)過小(xiao)會加大(da)管(guan)(guan)路內(nei)介質(zhi)的(de)(de)流速，使系統發(fa)熱，降低效率，而(er)且會產(chan)生過大(da)的(de)(de)壓力降，影(ying)(ying)響整個系統的(de)(de)性能。若膠管(guan)(guan)采用(yong)管(guan)(guan)夾固定或膠管(guan)(guan)穿(chuan)過鋼板(ban)等間隔物(wu)時(shi)，也(ye)要注意膠管(guan)(guan)的(de)(de)外(wai)徑(jing)尺寸。因此膠管(guan)(guan)使用(yong)壽命長短，不(bu)僅決定于質(zhi)量的(de)(de)好(hao)壞，同時(shi)也(ye)決定于正(zheng)確使用(yong)保(bao)養。所以即使產(chan)品有極高的(de)(de)質(zhi)量，如不(bu)能正(zheng)確地(di)使用(yong)和保(bao)養，也(ye)會嚴(yan)(yan)重影(ying)(ying)響其使用(yong)質(zhi)量和壽命，甚至發(fa)生不(bu)應有的(de)(de)嚴(yan)(yan)重事故，對財物(wu)造成損失。

液壓膠管使用(yong)注意事(shi)項由于膠(jiao)(jiao)管(guan)(guan)(guan)(guan)品(pin)種復(fu)雜(za)，結構多樣，加(jia)之使用(yong)條件不一，外膠(jiao)(jiao)層保護增強層不受損(sun)傷，增強層是骨架材料(liao)，作(zuo)用(yong)是保證膠(jiao)(jiao)管(guan)(guan)(guan)(guan)的使用(yong)壓(ya)(ya)(ya)(ya)(ya)力。液(ye)壓(ya)(ya)(ya)(ya)(ya)膠(jiao)(jiao)管(guan)(guan)(guan)(guan)別名液(ye)壓(ya)(ya)(ya)(ya)(ya)油(you)管(guan)(guan)(guan)(guan)、液(ye)壓(ya)(ya)(ya)(ya)(ya)軟管(guan)(guan)(guan)(guan)、 高壓(ya)(ya)(ya)(ya)(ya)膠(jiao)(jiao)管(guan)(guan)(guan)(guan)、液(ye)壓(ya)(ya)(ya)(ya)(ya)管(guan)(guan)(guan)(guan)、 鋼(gang)絲(si)(si)高壓(ya)(ya)(ya)(ya)(ya)管(guan)(guan)(guan)(guan)、 鋼(gang)絲(si)(si)編(bian)織膠(jiao)(jiao)管(guan)(guan)(guan)(guan) 鋼(gang)絲(si)(si)纏(chan)繞(rao)膠(jiao)(jiao)管(guan)(guan)(guan)(guan) ，一般分為(wei)鋼(gang)絲(si)(si)編(bian)織液(ye)壓(ya)(ya)(ya)(ya)(ya)膠(jiao)(jiao)管(guan)(guan)(guan)(guan)和鋼(gang)絲(si)(si)纏(chan)繞(rao)液(ye)壓(ya)(ya)(ya)(ya)(ya)膠(jiao)(jiao)管(guan)(guan)(guan)(guan)，內膠(jiao)(jiao)層具有使輸送介質承受壓(ya)(ya)(ya)(ya)(ya)力，保護鋼(gang)絲(si)(si)或線纖(xian)維不受侵蝕的作(zuo)用(yong)。
