膠管內(nei)徑要適當。管(guan)(guan)徑過(guo)小會加大管(guan)(guan)路內(nei)介質(zhi)的(de)流速，使系(xi)統發(fa)熱(re)，降低效(xiao)率，而且(qie)會產生過(guo)大的(de)壓力降，影響整個(ge)系(xi)統的(de)性能(neng)。若膠管(guan)(guan)采(cai)用(yong)(yong)(yong)管(guan)(guan)夾固定(ding)或膠管(guan)(guan)穿過(guo)鋼板(ban)等間隔(ge)物時(shi)(shi)，也要注(zhu)意膠管(guan)(guan)的(de)外徑尺寸。因此膠管(guan)(guan)使用(yong)(yong)(yong)壽(shou)命長短，不僅決定(ding)于質(zhi)量的(de)好壞，同時(shi)(shi)也決定(ding)于正(zheng)確使用(yong)(yong)(yong)保(bao)養(yang)。所以即使產品有極高的(de)質(zhi)量，如(ru)不能(neng)正(zheng)確地使用(yong)(yong)(yong)和保(bao)養(yang)，也會嚴重(zhong)影響其(qi)使用(yong)(yong)(yong)質(zhi)量和壽(shou)命，甚至發(fa)生不應有的(de)嚴重(zhong)事(shi)故(gu)，對財(cai)物造成(cheng)損失。

液壓膠管使(shi)用(yong)(yong)注(zhu)意事項由于膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)品種復雜，結構多樣，加之使(shi)用(yong)(yong)條件不(bu)一，外膠(jiao)(jiao)(jiao)層(ceng)保護增強層(ceng)不(bu)受損(sun)傷(shang)，增強層(ceng)是骨架材料，作(zuo)用(yong)(yong)是保證膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)的使(shi)用(yong)(yong)壓(ya)(ya)(ya)(ya)力(li)。液(ye)壓(ya)(ya)(ya)(ya)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)別(bie)名液(ye)壓(ya)(ya)(ya)(ya)油管(guan)(guan)(guan)、液(ye)壓(ya)(ya)(ya)(ya)軟管(guan)(guan)(guan)、 高(gao)壓(ya)(ya)(ya)(ya)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)、液(ye)壓(ya)(ya)(ya)(ya)管(guan)(guan)(guan)、 鋼(gang)絲高(gao)壓(ya)(ya)(ya)(ya)管(guan)(guan)(guan)、 鋼(gang)絲編織膠(jiao)(jiao)(jiao)管(guan)(guan)(guan) 鋼(gang)絲纏(chan)繞(rao)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan) ，一般分為鋼(gang)絲編織液(ye)壓(ya)(ya)(ya)(ya)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)和鋼(gang)絲纏(chan)繞(rao)液(ye)壓(ya)(ya)(ya)(ya)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)，內(nei)膠(jiao)(jiao)(jiao)層(ceng)具有(you)使(shi)輸送介質承受壓(ya)(ya)(ya)(ya)力(li)，保護鋼(gang)絲或線纖維不(bu)受侵蝕的作(zuo)用(yong)(yong)。
