膠管內徑(jing)要適當。管(guan)(guan)(guan)徑(jing)過小會加大管(guan)(guan)(guan)路內介質(zhi)(zhi)的(de)流(liu)速，使(shi)(shi)系統(tong)發熱，降(jiang)低(di)效率(lv)，而且會產生過大的(de)壓力降(jiang)，影(ying)響整個(ge)系統(tong)的(de)性能(neng)。若膠(jiao)管(guan)(guan)(guan)采用管(guan)(guan)(guan)夾固定或(huo)膠(jiao)管(guan)(guan)(guan)穿過鋼板等間隔物(wu)時，也(ye)要注意膠(jiao)管(guan)(guan)(guan)的(de)外徑(jing)尺寸(cun)。因此膠(jiao)管(guan)(guan)(guan)使(shi)(shi)用壽命長短(duan)，不僅決(jue)定于(yu)(yu)質(zhi)(zhi)量(liang)的(de)好(hao)壞(huai)，同(tong)時也(ye)決(jue)定于(yu)(yu)正(zheng)確使(shi)(shi)用保(bao)養。所以即使(shi)(shi)產品有(you)極高的(de)質(zhi)(zhi)量(liang)，如不能(neng)正(zheng)確地使(shi)(shi)用和保(bao)養，也(ye)會嚴重影(ying)響其使(shi)(shi)用質(zhi)(zhi)量(liang)和壽命，甚至(zhi)發生不應(ying)有(you)的(de)嚴重事故，對財物(wu)造成損失(shi)。

液壓膠管使(shi)用(yong)注意事(shi)項由于膠(jiao)(jiao)(jiao)管(guan)(guan)品種復(fu)雜，結(jie)構多樣，加之使(shi)用(yong)條件不(bu)一，外膠(jiao)(jiao)(jiao)層(ceng)保護增強層(ceng)不(bu)受損傷，增強層(ceng)是骨架材料，作(zuo)用(yong)是保證膠(jiao)(jiao)(jiao)管(guan)(guan)的使(shi)用(yong)壓(ya)(ya)(ya)(ya)力。液壓(ya)(ya)(ya)(ya)膠(jiao)(jiao)(jiao)管(guan)(guan)別名液壓(ya)(ya)(ya)(ya)油管(guan)(guan)、液壓(ya)(ya)(ya)(ya)軟(ruan)管(guan)(guan)、 高(gao)壓(ya)(ya)(ya)(ya)膠(jiao)(jiao)(jiao)管(guan)(guan)、液壓(ya)(ya)(ya)(ya)管(guan)(guan)、 鋼(gang)絲(si)高(gao)壓(ya)(ya)(ya)(ya)管(guan)(guan)、 鋼(gang)絲(si)編織膠(jiao)(jiao)(jiao)管(guan)(guan) 鋼(gang)絲(si)纏繞(rao)膠(jiao)(jiao)(jiao)管(guan)(guan) ，一般分(fen)為鋼(gang)絲(si)編織液壓(ya)(ya)(ya)(ya)膠(jiao)(jiao)(jiao)管(guan)(guan)和鋼(gang)絲(si)纏繞(rao)液壓(ya)(ya)(ya)(ya)膠(jiao)(jiao)(jiao)管(guan)(guan)，內膠(jiao)(jiao)(jiao)層(ceng)具有(you)使(shi)輸送介質承受壓(ya)(ya)(ya)(ya)力，保護鋼(gang)絲(si)或線纖維不(bu)受侵蝕(shi)的作(zuo)用(yong)。
