膠管內徑要適當。管徑過(guo)小會加大管路內介(jie)質的流速(su)，使(shi)系統發熱，降(jiang)低(di)效率，而且會產生(sheng)過(guo)大的壓力降(jiang)，影響整個系統的性能(neng)。若膠管采用(yong)(yong)管夾固定或膠管穿過(guo)鋼板等間隔物時，也要注意膠管的外徑尺(chi)寸(cun)。因(yin)此(ci)膠管使(shi)用(yong)(yong)壽(shou)命長短，不僅決(jue)定于質量的好壞，同時也決(jue)定于正(zheng)確(que)使(shi)用(yong)(yong)保養(yang)。所以即(ji)使(shi)產品有極高的質量，如不能(neng)正(zheng)確(que)地使(shi)用(yong)(yong)和保養(yang)，也會嚴(yan)重影響其使(shi)用(yong)(yong)質量和壽(shou)命，甚(shen)至發生(sheng)不應有的嚴(yan)重事(shi)故，對(dui)財物造成損失。

液壓膠管使(shi)用(yong)(yong)注意事項由于膠(jiao)管(guan)(guan)(guan)品種復雜，結構多(duo)樣，加(jia)之(zhi)使(shi)用(yong)(yong)條件不(bu)(bu)一，外膠(jiao)層(ceng)(ceng)保(bao)護增強(qiang)(qiang)層(ceng)(ceng)不(bu)(bu)受(shou)損傷，增強(qiang)(qiang)層(ceng)(ceng)是骨(gu)架材料，作用(yong)(yong)是保(bao)證(zheng)膠(jiao)管(guan)(guan)(guan)的使(shi)用(yong)(yong)壓力(li)。液壓膠(jiao)管(guan)(guan)(guan)別名液壓油管(guan)(guan)(guan)、液壓軟(ruan)管(guan)(guan)(guan)、 高壓膠(jiao)管(guan)(guan)(guan)、液壓管(guan)(guan)(guan)、 鋼(gang)(gang)絲(si)高壓管(guan)(guan)(guan)、 鋼(gang)(gang)絲(si)編(bian)織膠(jiao)管(guan)(guan)(guan) 鋼(gang)(gang)絲(si)纏繞膠(jiao)管(guan)(guan)(guan) ，一般分為鋼(gang)(gang)絲(si)編(bian)織液壓膠(jiao)管(guan)(guan)(guan)和鋼(gang)(gang)絲(si)纏繞液壓膠(jiao)管(guan)(guan)(guan)，內膠(jiao)層(ceng)(ceng)具有使(shi)輸送介(jie)質承受(shou)壓力(li)，保(bao)護鋼(gang)(gang)絲(si)或線纖維(wei)不(bu)(bu)受(shou)侵蝕的作用(yong)(yong)。
