膠管內徑要適當。管徑過小(xiao)會加大管路內介質(zhi)的(de)流速，使(shi)(shi)系統發熱，降(jiang)低效率，而且(qie)會產(chan)生過大的(de)壓力降(jiang)，影響整(zheng)個(ge)系統的(de)性能。若(ruo)膠(jiao)管采(cai)用(yong)管夾固定(ding)(ding)或(huo)膠(jiao)管穿過鋼板等(deng)間隔(ge)物時(shi)，也(ye)要注意(yi)膠(jiao)管的(de)外徑尺寸。因此膠(jiao)管使(shi)(shi)用(yong)壽命長短，不僅(jin)決定(ding)(ding)于(yu)質(zhi)量的(de)好壞(huai)，同時(shi)也(ye)決定(ding)(ding)于(yu)正確使(shi)(shi)用(yong)保養。所以即使(shi)(shi)產(chan)品有極高的(de)質(zhi)量，如不能正確地使(shi)(shi)用(yong)和保養，也(ye)會嚴(yan)(yan)重(zhong)影響其(qi)使(shi)(shi)用(yong)質(zhi)量和壽命，甚至發生不應有的(de)嚴(yan)(yan)重(zhong)事故，對財物造(zao)成損失。
