膠管內(nei)(nei)徑要適當(dang)。管(guan)(guan)徑過小會加大(da)管(guan)(guan)路內(nei)(nei)介質的(de)(de)流速，使(shi)(shi)系統發熱(re)，降(jiang)(jiang)低(di)效率，而且會產生(sheng)過大(da)的(de)(de)壓力降(jiang)(jiang)，影響整個系統的(de)(de)性能。若膠管(guan)(guan)采(cai)用(yong)管(guan)(guan)夾固定或膠管(guan)(guan)穿過鋼板等間隔物時(shi)，也(ye)要注意膠管(guan)(guan)的(de)(de)外徑尺(chi)寸(cun)。因此膠管(guan)(guan)使(shi)(shi)用(yong)壽(shou)命(ming)長短，不僅決(jue)定于質量的(de)(de)好壞，同(tong)時(shi)也(ye)決(jue)定于正確使(shi)(shi)用(yong)保養。所(suo)以(yi)即使(shi)(shi)產品有極高的(de)(de)質量，如(ru)不能正確地使(shi)(shi)用(yong)和(he)保養，也(ye)會嚴重(zhong)影響其使(shi)(shi)用(yong)質量和(he)壽(shou)命(ming)，甚至發生(sheng)不應有的(de)(de)嚴重(zhong)事故，對(dui)財物造(zao)成損失。

液壓膠管使(shi)用注意(yi)事(shi)項由于(yu)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)品種復雜，結構多樣，加之使(shi)用條件不(bu)一，外膠(jiao)(jiao)(jiao)(jiao)層保護增強層不(bu)受損傷，增強層是骨架材料，作用是保證膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)的使(shi)用壓(ya)(ya)力(li)。液(ye)(ye)壓(ya)(ya)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)別名(ming)液(ye)(ye)壓(ya)(ya)油管(guan)(guan)(guan)(guan)、液(ye)(ye)壓(ya)(ya)軟管(guan)(guan)(guan)(guan)、 高壓(ya)(ya)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)、液(ye)(ye)壓(ya)(ya)管(guan)(guan)(guan)(guan)、 鋼(gang)絲(si)高壓(ya)(ya)管(guan)(guan)(guan)(guan)、 鋼(gang)絲(si)編織(zhi)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan) 鋼(gang)絲(si)纏繞膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan) ，一般分為鋼(gang)絲(si)編織(zhi)液(ye)(ye)壓(ya)(ya)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)和鋼(gang)絲(si)纏繞液(ye)(ye)壓(ya)(ya)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)(guan)(guan)，內(nei)膠(jiao)(jiao)(jiao)(jiao)層具有使(shi)輸(shu)送介質承受壓(ya)(ya)力(li)，保護鋼(gang)絲(si)或線纖維(wei)不(bu)受侵蝕的作用。
