膠管內徑(jing)要適(shi)當。管(guan)(guan)(guan)徑(jing)過小(xiao)會(hui)加大(da)管(guan)(guan)(guan)路內介質(zhi)(zhi)的(de)流速(su)，使系(xi)(xi)統(tong)發熱，降低效率，而且會(hui)產生(sheng)(sheng)過大(da)的(de)壓力(li)降，影響(xiang)整個系(xi)(xi)統(tong)的(de)性能。若膠(jiao)管(guan)(guan)(guan)采(cai)用(yong)(yong)管(guan)(guan)(guan)夾固定(ding)(ding)或膠(jiao)管(guan)(guan)(guan)穿過鋼板等間隔(ge)物(wu)時(shi)，也要注意膠(jiao)管(guan)(guan)(guan)的(de)外徑(jing)尺寸。因此膠(jiao)管(guan)(guan)(guan)使用(yong)(yong)壽命長短(duan)，不(bu)(bu)僅(jin)決定(ding)(ding)于質(zhi)(zhi)量(liang)的(de)好(hao)壞(huai)，同時(shi)也決定(ding)(ding)于正確使用(yong)(yong)保養。所以即使產品有(you)極高(gao)的(de)質(zhi)(zhi)量(liang)，如不(bu)(bu)能正確地使用(yong)(yong)和保養，也會(hui)嚴重影響(xiang)其使用(yong)(yong)質(zhi)(zhi)量(liang)和壽命，甚至發生(sheng)(sheng)不(bu)(bu)應有(you)的(de)嚴重事故，對財物(wu)造成(cheng)損失(shi)。
