膠管內徑要適當(dang)。管(guan)徑過(guo)小會加大(da)管(guan)路內介質(zhi)的流速，使系統(tong)發熱，降(jiang)低效率(lv)，而且會產生過(guo)大(da)的壓力降(jiang)，影(ying)響整個系統(tong)的性能。若(ruo)膠(jiao)管(guan)采用管(guan)夾固定(ding)(ding)或膠(jiao)管(guan)穿過(guo)鋼板等間隔物時(shi)，也要注意(yi)膠(jiao)管(guan)的外徑尺寸(cun)。因此(ci)膠(jiao)管(guan)使用壽命(ming)長短，不僅(jin)決(jue)定(ding)(ding)于質(zhi)量的好壞，同(tong)時(shi)也決(jue)定(ding)(ding)于正確(que)使用保養。所以即使產品(pin)有(you)極高的質(zhi)量，如不能正確(que)地使用和保養，也會嚴(yan)重影(ying)響其(qi)使用質(zhi)量和壽命(ming)，甚至發生不應有(you)的嚴(yan)重事(shi)故，對財物造(zao)成(cheng)損失。

液壓膠管使用(yong)(yong)注意(yi)事項由于膠(jiao)(jiao)管(guan)(guan)品種復雜，結構多樣，加之(zhi)使用(yong)(yong)條件不(bu)一，外膠(jiao)(jiao)層(ceng)保護(hu)增(zeng)強層(ceng)不(bu)受(shou)損傷，增(zeng)強層(ceng)是骨架材料，作(zuo)用(yong)(yong)是保證膠(jiao)(jiao)管(guan)(guan)的使用(yong)(yong)壓(ya)(ya)(ya)(ya)(ya)力。液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)膠(jiao)(jiao)管(guan)(guan)別(bie)名液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)油(you)管(guan)(guan)、液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)軟管(guan)(guan)、 高壓(ya)(ya)(ya)(ya)(ya)膠(jiao)(jiao)管(guan)(guan)、液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)管(guan)(guan)、 鋼(gang)(gang)絲(si)(si)高壓(ya)(ya)(ya)(ya)(ya)管(guan)(guan)、 鋼(gang)(gang)絲(si)(si)編織膠(jiao)(jiao)管(guan)(guan) 鋼(gang)(gang)絲(si)(si)纏(chan)繞膠(jiao)(jiao)管(guan)(guan) ，一般(ban)分為(wei)鋼(gang)(gang)絲(si)(si)編織液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)膠(jiao)(jiao)管(guan)(guan)和鋼(gang)(gang)絲(si)(si)纏(chan)繞液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)膠(jiao)(jiao)管(guan)(guan)，內膠(jiao)(jiao)層(ceng)具(ju)有使輸(shu)送(song)介質承受(shou)壓(ya)(ya)(ya)(ya)(ya)力，保護(hu)鋼(gang)(gang)絲(si)(si)或線纖維不(bu)受(shou)侵蝕的作(zuo)用(yong)(yong)。
