膠管內(nei)(nei)徑(jing)要適(shi)當。管(guan)徑(jing)過小會加大管(guan)路(lu)內(nei)(nei)介質(zhi)(zhi)(zhi)的流速，使(shi)(shi)系統發(fa)(fa)熱，降低(di)效率，而且會產生(sheng)過大的壓力降，影響整個系統的性能。若膠管(guan)采(cai)用管(guan)夾固定(ding)或(huo)膠管(guan)穿過鋼板等間隔物時，也要注意膠管(guan)的外徑(jing)尺(chi)寸。因此膠管(guan)使(shi)(shi)用壽命(ming)長短，不僅決(jue)定(ding)于質(zhi)(zhi)(zhi)量(liang)的好壞，同時也決(jue)定(ding)于正確(que)(que)使(shi)(shi)用保養。所(suo)以即使(shi)(shi)產品有(you)(you)極高的質(zhi)(zhi)(zhi)量(liang)，如(ru)不能正確(que)(que)地(di)使(shi)(shi)用和(he)保養，也會嚴(yan)重影響其使(shi)(shi)用質(zhi)(zhi)(zhi)量(liang)和(he)壽命(ming)，甚至(zhi)發(fa)(fa)生(sheng)不應有(you)(you)的嚴(yan)重事故，對財物造成損失。

液壓膠管使(shi)用注意(yi)事項由于膠(jiao)(jiao)管(guan)(guan)品種(zhong)復雜，結(jie)構(gou)多樣，加之使(shi)用條(tiao)件不(bu)一，外膠(jiao)(jiao)層(ceng)(ceng)保(bao)(bao)護(hu)增強層(ceng)(ceng)不(bu)受損傷(shang)，增強層(ceng)(ceng)是骨架材料，作(zuo)用是保(bao)(bao)證膠(jiao)(jiao)管(guan)(guan)的使(shi)用壓(ya)(ya)(ya)力。液壓(ya)(ya)(ya)膠(jiao)(jiao)管(guan)(guan)別(bie)名(ming)液壓(ya)(ya)(ya)油管(guan)(guan)、液壓(ya)(ya)(ya)軟(ruan)管(guan)(guan)、 高(gao)壓(ya)(ya)(ya)膠(jiao)(jiao)管(guan)(guan)、液壓(ya)(ya)(ya)管(guan)(guan)、 鋼(gang)(gang)(gang)絲高(gao)壓(ya)(ya)(ya)管(guan)(guan)、 鋼(gang)(gang)(gang)絲編織膠(jiao)(jiao)管(guan)(guan) 鋼(gang)(gang)(gang)絲纏繞膠(jiao)(jiao)管(guan)(guan) ，一般分為鋼(gang)(gang)(gang)絲編織液壓(ya)(ya)(ya)膠(jiao)(jiao)管(guan)(guan)和鋼(gang)(gang)(gang)絲纏繞液壓(ya)(ya)(ya)膠(jiao)(jiao)管(guan)(guan)，內膠(jiao)(jiao)層(ceng)(ceng)具有(you)使(shi)輸送介質承受壓(ya)(ya)(ya)力，保(bao)(bao)護(hu)鋼(gang)(gang)(gang)絲或線纖維不(bu)受侵蝕的作(zuo)用。
