膠管內徑要適當。管(guan)徑過(guo)小(xiao)會加大管(guan)路內介(jie)質的流(liu)速，使系(xi)統發熱(re)，降低效率，而且會產(chan)生過(guo)大的壓力降，影響整(zheng)個系(xi)統的性能(neng)。若膠(jiao)(jiao)(jiao)管(guan)采用(yong)管(guan)夾固(gu)定(ding)或(huo)膠(jiao)(jiao)(jiao)管(guan)穿過(guo)鋼板(ban)等間隔物時(shi)，也(ye)要注意膠(jiao)(jiao)(jiao)管(guan)的外徑尺寸(cun)。因此膠(jiao)(jiao)(jiao)管(guan)使用(yong)壽(shou)命(ming)長短，不僅決定(ding)于質量(liang)的好壞，同時(shi)也(ye)決定(ding)于正(zheng)(zheng)確使用(yong)保養。所以即(ji)使產(chan)品(pin)有極(ji)高的質量(liang)，如(ru)不能(neng)正(zheng)(zheng)確地(di)使用(yong)和(he)保養，也(ye)會嚴(yan)重影響其使用(yong)質量(liang)和(he)壽(shou)命(ming)，甚至(zhi)發生不應有的嚴(yan)重事故，對(dui)財物造成損失。
