膠管內(nei)徑(jing)要適(shi)當(dang)。管(guan)徑(jing)過(guo)(guo)小會(hui)(hui)加(jia)大(da)管(guan)路(lu)內(nei)介質(zhi)的流速，使(shi)系統發熱，降(jiang)低效率，而且會(hui)(hui)產生過(guo)(guo)大(da)的壓(ya)力降(jiang)，影響(xiang)(xiang)整(zheng)個(ge)系統的性能(neng)。若(ruo)膠管(guan)采用(yong)(yong)管(guan)夾固(gu)定或膠管(guan)穿過(guo)(guo)鋼板等間隔物時(shi)，也(ye)(ye)要注意(yi)膠管(guan)的外徑(jing)尺(chi)寸。因此膠管(guan)使(shi)用(yong)(yong)壽(shou)命長短，不僅(jin)決定于質(zhi)量(liang)的好壞(huai)，同時(shi)也(ye)(ye)決定于正確使(shi)用(yong)(yong)保養(yang)(yang)。所以即使(shi)產品(pin)有極高的質(zhi)量(liang)，如(ru)不能(neng)正確地使(shi)用(yong)(yong)和保養(yang)(yang)，也(ye)(ye)會(hui)(hui)嚴(yan)(yan)重影響(xiang)(xiang)其(qi)使(shi)用(yong)(yong)質(zhi)量(liang)和壽(shou)命，甚至發生不應有的嚴(yan)(yan)重事故，對財(cai)物造成(cheng)損失(shi)。

液壓膠管使用(yong)注意事(shi)項由于膠(jiao)(jiao)管(guan)(guan)(guan)(guan)品種(zhong)復雜，結構(gou)多樣，加之使用(yong)條件(jian)不(bu)(bu)一，外(wai)膠(jiao)(jiao)層(ceng)保護增(zeng)強(qiang)層(ceng)不(bu)(bu)受損傷，增(zeng)強(qiang)層(ceng)是骨架(jia)材料，作(zuo)用(yong)是保證(zheng)膠(jiao)(jiao)管(guan)(guan)(guan)(guan)的使用(yong)壓(ya)(ya)力(li)。液壓(ya)(ya)膠(jiao)(jiao)管(guan)(guan)(guan)(guan)別名(ming)液壓(ya)(ya)油(you)管(guan)(guan)(guan)(guan)、液壓(ya)(ya)軟管(guan)(guan)(guan)(guan)、 高(gao)壓(ya)(ya)膠(jiao)(jiao)管(guan)(guan)(guan)(guan)、液壓(ya)(ya)管(guan)(guan)(guan)(guan)、 鋼(gang)絲(si)高(gao)壓(ya)(ya)管(guan)(guan)(guan)(guan)、 鋼(gang)絲(si)編(bian)織膠(jiao)(jiao)管(guan)(guan)(guan)(guan) 鋼(gang)絲(si)纏(chan)繞膠(jiao)(jiao)管(guan)(guan)(guan)(guan) ，一般分(fen)為鋼(gang)絲(si)編(bian)織液壓(ya)(ya)膠(jiao)(jiao)管(guan)(guan)(guan)(guan)和鋼(gang)絲(si)纏(chan)繞液壓(ya)(ya)膠(jiao)(jiao)管(guan)(guan)(guan)(guan)，內膠(jiao)(jiao)層(ceng)具有使輸送介質承(cheng)受壓(ya)(ya)力(li)，保護鋼(gang)絲(si)或線纖維不(bu)(bu)受侵(qin)蝕的作(zuo)用(yong)。
