膠管內(nei)徑(jing)要(yao)適當。管(guan)(guan)徑(jing)過小(xiao)會(hui)加大管(guan)(guan)路(lu)內(nei)介質(zhi)(zhi)的(de)流速，使(shi)(shi)系統(tong)發熱，降(jiang)低效率，而且(qie)會(hui)產(chan)(chan)生過大的(de)壓力(li)降(jiang)，影響整個(ge)系統(tong)的(de)性(xing)能(neng)。若膠管(guan)(guan)采用(yong)(yong)管(guan)(guan)夾固(gu)定或膠管(guan)(guan)穿過鋼板等(deng)間隔物時，也(ye)要(yao)注意膠管(guan)(guan)的(de)外徑(jing)尺寸(cun)。因此膠管(guan)(guan)使(shi)(shi)用(yong)(yong)壽命(ming)長短，不(bu)僅決(jue)定于(yu)質(zhi)(zhi)量(liang)的(de)好壞，同(tong)時也(ye)決(jue)定于(yu)正(zheng)確使(shi)(shi)用(yong)(yong)保(bao)養。所以即使(shi)(shi)產(chan)(chan)品有極(ji)高的(de)質(zhi)(zhi)量(liang)，如不(bu)能(neng)正(zheng)確地使(shi)(shi)用(yong)(yong)和(he)保(bao)養，也(ye)會(hui)嚴重(zhong)影響其使(shi)(shi)用(yong)(yong)質(zhi)(zhi)量(liang)和(he)壽命(ming)，甚至發生不(bu)應(ying)有的(de)嚴重(zhong)事故，對(dui)財物造成損失。

液壓膠管使(shi)用(yong)(yong)注意(yi)事(shi)項由于膠(jiao)(jiao)管(guan)(guan)(guan)(guan)品種復雜，結構多樣，加之使(shi)用(yong)(yong)條件不一，外膠(jiao)(jiao)層(ceng)保護增強(qiang)層(ceng)不受損(sun)傷，增強(qiang)層(ceng)是骨架材料，作(zuo)用(yong)(yong)是保證膠(jiao)(jiao)管(guan)(guan)(guan)(guan)的使(shi)用(yong)(yong)壓(ya)力(li)。液(ye)(ye)壓(ya)膠(jiao)(jiao)管(guan)(guan)(guan)(guan)別名液(ye)(ye)壓(ya)油管(guan)(guan)(guan)(guan)、液(ye)(ye)壓(ya)軟管(guan)(guan)(guan)(guan)、 高壓(ya)膠(jiao)(jiao)管(guan)(guan)(guan)(guan)、液(ye)(ye)壓(ya)管(guan)(guan)(guan)(guan)、 鋼(gang)絲高壓(ya)管(guan)(guan)(guan)(guan)、 鋼(gang)絲編織膠(jiao)(jiao)管(guan)(guan)(guan)(guan) 鋼(gang)絲纏繞膠(jiao)(jiao)管(guan)(guan)(guan)(guan) ，一般分為鋼(gang)絲編織液(ye)(ye)壓(ya)膠(jiao)(jiao)管(guan)(guan)(guan)(guan)和(he)鋼(gang)絲纏繞液(ye)(ye)壓(ya)膠(jiao)(jiao)管(guan)(guan)(guan)(guan)，內(nei)膠(jiao)(jiao)層(ceng)具有使(shi)輸送(song)介質(zhi)承受壓(ya)力(li)，保護鋼(gang)絲或線(xian)纖維不受侵蝕的作(zuo)用(yong)(yong)。
