膠管內徑(jing)要適當(dang)。管(guan)(guan)(guan)徑(jing)過小會(hui)加大管(guan)(guan)(guan)路內介質(zhi)的(de)流速，使(shi)系統(tong)(tong)發熱，降低(di)效率，而且會(hui)產生(sheng)過大的(de)壓力降，影(ying)響整個系統(tong)(tong)的(de)性(xing)能(neng)。若(ruo)膠管(guan)(guan)(guan)采用(yong)管(guan)(guan)(guan)夾固定或膠管(guan)(guan)(guan)穿過鋼(gang)板等間(jian)隔物時，也要注意膠管(guan)(guan)(guan)的(de)外徑(jing)尺寸。因此膠管(guan)(guan)(guan)使(shi)用(yong)壽命長短，不僅決(jue)定于(yu)質(zhi)量的(de)好壞，同時也決(jue)定于(yu)正(zheng)確(que)(que)使(shi)用(yong)保養。所(suo)以即使(shi)產品有(you)極高的(de)質(zhi)量，如不能(neng)正(zheng)確(que)(que)地(di)使(shi)用(yong)和保養，也會(hui)嚴重影(ying)響其使(shi)用(yong)質(zhi)量和壽命，甚(shen)至發生(sheng)不應有(you)的(de)嚴重事故，對(dui)財(cai)物造成損失。

液壓膠管使(shi)用注意(yi)事項由于膠(jiao)管(guan)(guan)(guan)品種復雜，結構多樣，加之(zhi)使(shi)用條件不一，外膠(jiao)層保護(hu)增強層不受(shou)損傷，增強層是骨(gu)架材(cai)料，作(zuo)用是保證膠(jiao)管(guan)(guan)(guan)的使(shi)用壓(ya)(ya)(ya)力。液(ye)壓(ya)(ya)(ya)膠(jiao)管(guan)(guan)(guan)別名液(ye)壓(ya)(ya)(ya)油管(guan)(guan)(guan)、液(ye)壓(ya)(ya)(ya)軟管(guan)(guan)(guan)、 高壓(ya)(ya)(ya)膠(jiao)管(guan)(guan)(guan)、液(ye)壓(ya)(ya)(ya)管(guan)(guan)(guan)、 鋼(gang)(gang)絲(si)高壓(ya)(ya)(ya)管(guan)(guan)(guan)、 鋼(gang)(gang)絲(si)編織(zhi)膠(jiao)管(guan)(guan)(guan) 鋼(gang)(gang)絲(si)纏繞(rao)膠(jiao)管(guan)(guan)(guan) ，一般分(fen)為鋼(gang)(gang)絲(si)編織(zhi)液(ye)壓(ya)(ya)(ya)膠(jiao)管(guan)(guan)(guan)和鋼(gang)(gang)絲(si)纏繞(rao)液(ye)壓(ya)(ya)(ya)膠(jiao)管(guan)(guan)(guan)，內膠(jiao)層具有使(shi)輸送介質承受(shou)壓(ya)(ya)(ya)力，保護(hu)鋼(gang)(gang)絲(si)或線纖維不受(shou)侵(qin)蝕的作(zuo)用。
