膠管內徑要適當。管(guan)徑過(guo)小會加大(da)管(guan)路內介質的(de)流速，使(shi)系統(tong)發(fa)熱，降低效(xiao)率，而且(qie)會產生過(guo)大(da)的(de)壓力降，影響整(zheng)個系統(tong)的(de)性能(neng)(neng)。若膠(jiao)(jiao)(jiao)管(guan)采用(yong)管(guan)夾固定(ding)(ding)或膠(jiao)(jiao)(jiao)管(guan)穿過(guo)鋼板等間隔(ge)物(wu)(wu)時(shi)，也(ye)要注(zhu)意(yi)膠(jiao)(jiao)(jiao)管(guan)的(de)外(wai)徑尺寸。因此膠(jiao)(jiao)(jiao)管(guan)使(shi)用(yong)壽命長短，不僅決(jue)(jue)定(ding)(ding)于質量(liang)(liang)的(de)好壞(huai)，同時(shi)也(ye)決(jue)(jue)定(ding)(ding)于正確(que)使(shi)用(yong)保養(yang)。所以即使(shi)產品有極高的(de)質量(liang)(liang)，如不能(neng)(neng)正確(que)地使(shi)用(yong)和保養(yang)，也(ye)會嚴(yan)重影響其使(shi)用(yong)質量(liang)(liang)和壽命，甚至(zhi)發(fa)生不應有的(de)嚴(yan)重事故，對財物(wu)(wu)造成損失。
