膠管內(nei)徑要(yao)(yao)適當(dang)。管(guan)(guan)(guan)徑過(guo)小會加大管(guan)(guan)(guan)路內(nei)介質的流速，使系統發熱，降低(di)效率，而且會產生過(guo)大的壓(ya)力降，影響整(zheng)個系統的性能。若膠(jiao)管(guan)(guan)(guan)采用(yong)管(guan)(guan)(guan)夾固定(ding)或膠(jiao)管(guan)(guan)(guan)穿過(guo)鋼板等間隔物時(shi)，也(ye)要(yao)(yao)注意膠(jiao)管(guan)(guan)(guan)的外徑尺(chi)寸。因(yin)此膠(jiao)管(guan)(guan)(guan)使用(yong)壽(shou)命(ming)長短，不僅(jin)決(jue)定(ding)于(yu)(yu)質量(liang)的好壞(huai)，同時(shi)也(ye)決(jue)定(ding)于(yu)(yu)正(zheng)確使用(yong)保養。所以即使產品有(you)極(ji)高的質量(liang)，如不能正(zheng)確地使用(yong)和保養，也(ye)會嚴(yan)重影響其使用(yong)質量(liang)和壽(shou)命(ming)，甚至(zhi)發生不應(ying)有(you)的嚴(yan)重事(shi)故，對財物造成損失。

液壓膠管使用(yong)(yong)注意(yi)事項由于(yu)膠(jiao)管(guan)(guan)品種復雜，結(jie)構多樣(yang)，加之(zhi)使用(yong)(yong)條件不一，外(wai)膠(jiao)層(ceng)(ceng)(ceng)保護增強層(ceng)(ceng)(ceng)不受損(sun)傷，增強層(ceng)(ceng)(ceng)是(shi)骨架材料(liao)，作用(yong)(yong)是(shi)保證(zheng)膠(jiao)管(guan)(guan)的使用(yong)(yong)壓(ya)(ya)(ya)力(li)。液(ye)(ye)壓(ya)(ya)(ya)膠(jiao)管(guan)(guan)別(bie)名(ming)液(ye)(ye)壓(ya)(ya)(ya)油管(guan)(guan)、液(ye)(ye)壓(ya)(ya)(ya)軟(ruan)管(guan)(guan)、 高(gao)壓(ya)(ya)(ya)膠(jiao)管(guan)(guan)、液(ye)(ye)壓(ya)(ya)(ya)管(guan)(guan)、 鋼(gang)絲(si)高(gao)壓(ya)(ya)(ya)管(guan)(guan)、 鋼(gang)絲(si)編織(zhi)膠(jiao)管(guan)(guan) 鋼(gang)絲(si)纏繞(rao)膠(jiao)管(guan)(guan) ，一般分為鋼(gang)絲(si)編織(zhi)液(ye)(ye)壓(ya)(ya)(ya)膠(jiao)管(guan)(guan)和鋼(gang)絲(si)纏繞(rao)液(ye)(ye)壓(ya)(ya)(ya)膠(jiao)管(guan)(guan)，內膠(jiao)層(ceng)(ceng)(ceng)具有使輸(shu)送(song)介質承受壓(ya)(ya)(ya)力(li)，保護鋼(gang)絲(si)或線纖維不受侵蝕(shi)的作用(yong)(yong)。
