膠管內徑(jing)要適當。管(guan)(guan)徑(jing)過(guo)小會加大(da)管(guan)(guan)路內介質的(de)流速，使(shi)(shi)系統發熱，降低效率(lv)，而且會產(chan)生(sheng)(sheng)過(guo)大(da)的(de)壓(ya)力降，影響整個系統的(de)性(xing)能。若膠(jiao)管(guan)(guan)采用(yong)管(guan)(guan)夾(jia)固定(ding)或膠(jiao)管(guan)(guan)穿過(guo)鋼板等間(jian)隔物(wu)時(shi)，也(ye)要注意膠(jiao)管(guan)(guan)的(de)外徑(jing)尺(chi)寸。因此(ci)膠(jiao)管(guan)(guan)使(shi)(shi)用(yong)壽(shou)(shou)命長短，不僅決定(ding)于質量(liang)的(de)好壞，同時(shi)也(ye)決定(ding)于正確使(shi)(shi)用(yong)保(bao)養。所以即使(shi)(shi)產(chan)品有(you)極高的(de)質量(liang)，如(ru)不能正確地使(shi)(shi)用(yong)和保(bao)養，也(ye)會嚴(yan)重(zhong)影響其(qi)使(shi)(shi)用(yong)質量(liang)和壽(shou)(shou)命，甚至發生(sheng)(sheng)不應有(you)的(de)嚴(yan)重(zhong)事故，對(dui)財物(wu)造成損失。

液壓膠管使(shi)用注(zhu)意事項由于膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)品種復雜，結構(gou)多樣，加之使(shi)用條件不一(yi)，外膠(jiao)(jiao)(jiao)層保護增強層不受損傷，增強層是(shi)骨(gu)架材料，作用是(shi)保證膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)的使(shi)用壓(ya)(ya)(ya)(ya)(ya)力(li)(li)。液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)別名液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)油管(guan)(guan)(guan)、液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)軟管(guan)(guan)(guan)、 高壓(ya)(ya)(ya)(ya)(ya)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)、液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)管(guan)(guan)(guan)、 鋼絲(si)高壓(ya)(ya)(ya)(ya)(ya)管(guan)(guan)(guan)、 鋼絲(si)編織(zhi)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan) 鋼絲(si)纏(chan)繞膠(jiao)(jiao)(jiao)管(guan)(guan)(guan) ，一(yi)般分為鋼絲(si)編織(zhi)液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)和鋼絲(si)纏(chan)繞液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)，內膠(jiao)(jiao)(jiao)層具有使(shi)輸送介質承受壓(ya)(ya)(ya)(ya)(ya)力(li)(li)，保護鋼絲(si)或(huo)線纖(xian)維不受侵蝕的作用。
