膠管內徑(jing)要適當。管(guan)(guan)徑(jing)過小會加大(da)管(guan)(guan)路內介質的流速，使(shi)系(xi)統發熱(re)，降低效率，而(er)且會產(chan)生過大(da)的壓力降，影響(xiang)(xiang)整個系(xi)統的性能(neng)。若膠(jiao)管(guan)(guan)采用(yong)(yong)管(guan)(guan)夾固定或膠(jiao)管(guan)(guan)穿過鋼(gang)板等間(jian)隔物時，也要注意膠(jiao)管(guan)(guan)的外徑(jing)尺寸(cun)。因此膠(jiao)管(guan)(guan)使(shi)用(yong)(yong)壽命(ming)長短，不僅(jin)決(jue)定于(yu)質量的好壞，同時也決(jue)定于(yu)正確使(shi)用(yong)(yong)保養。所以即使(shi)產(chan)品有極高的質量，如不能(neng)正確地使(shi)用(yong)(yong)和保養，也會嚴(yan)重影響(xiang)(xiang)其使(shi)用(yong)(yong)質量和壽命(ming)，甚至發生不應(ying)有的嚴(yan)重事故，對(dui)財物造成(cheng)損失。
