膠管內(nei)徑(jing)(jing)要(yao)適當。管(guan)(guan)徑(jing)(jing)過(guo)小會加(jia)大管(guan)(guan)路內(nei)介質的(de)流速(su)，使(shi)系(xi)(xi)統發熱，降(jiang)(jiang)低(di)效率，而(er)且會產生過(guo)大的(de)壓力降(jiang)(jiang)，影(ying)響(xiang)整個系(xi)(xi)統的(de)性能。若膠(jiao)(jiao)管(guan)(guan)采用(yong)管(guan)(guan)夾固定(ding)或(huo)膠(jiao)(jiao)管(guan)(guan)穿(chuan)過(guo)鋼(gang)板等間(jian)隔物時，也要(yao)注意膠(jiao)(jiao)管(guan)(guan)的(de)外徑(jing)(jing)尺(chi)寸。因此膠(jiao)(jiao)管(guan)(guan)使(shi)用(yong)壽(shou)命長短，不(bu)僅決定(ding)于質量的(de)好壞，同時也決定(ding)于正確使(shi)用(yong)保(bao)養。所以即(ji)使(shi)產品有(you)極(ji)高的(de)質量，如(ru)不(bu)能正確地使(shi)用(yong)和保(bao)養，也會嚴重影(ying)響(xiang)其(qi)使(shi)用(yong)質量和壽(shou)命，甚至發生不(bu)應有(you)的(de)嚴重事(shi)故，對財物造(zao)成(cheng)損失。

液壓膠管使用(yong)注意事項由于膠(jiao)(jiao)管(guan)(guan)品種復雜，結(jie)構多樣(yang)，加之使用(yong)條件不(bu)一，外膠(jiao)(jiao)層保(bao)護(hu)增(zeng)強層不(bu)受(shou)損(sun)傷，增(zeng)強層是骨架材料，作用(yong)是保(bao)證膠(jiao)(jiao)管(guan)(guan)的使用(yong)壓(ya)(ya)力(li)。液(ye)壓(ya)(ya)膠(jiao)(jiao)管(guan)(guan)別名液(ye)壓(ya)(ya)油(you)管(guan)(guan)、液(ye)壓(ya)(ya)軟管(guan)(guan)、 高(gao)壓(ya)(ya)膠(jiao)(jiao)管(guan)(guan)、液(ye)壓(ya)(ya)管(guan)(guan)、 鋼絲(si)(si)高(gao)壓(ya)(ya)管(guan)(guan)、 鋼絲(si)(si)編織(zhi)膠(jiao)(jiao)管(guan)(guan) 鋼絲(si)(si)纏繞膠(jiao)(jiao)管(guan)(guan) ，一般分(fen)為(wei)鋼絲(si)(si)編織(zhi)液(ye)壓(ya)(ya)膠(jiao)(jiao)管(guan)(guan)和鋼絲(si)(si)纏繞液(ye)壓(ya)(ya)膠(jiao)(jiao)管(guan)(guan)，內膠(jiao)(jiao)層具有使輸送(song)介質承受(shou)壓(ya)(ya)力(li)，保(bao)護(hu)鋼絲(si)(si)或線纖(xian)維不(bu)受(shou)侵蝕的作用(yong)。
