膠管內(nei)徑要(yao)(yao)適當。管(guan)(guan)(guan)徑過(guo)小會加大管(guan)(guan)(guan)路(lu)內(nei)介質(zhi)的(de)流(liu)速(su)，使(shi)系統發熱(re)，降(jiang)低效率，而且會產(chan)生過(guo)大的(de)壓力降(jiang)，影(ying)響(xiang)(xiang)整個(ge)系統的(de)性能。若膠(jiao)(jiao)管(guan)(guan)(guan)采用管(guan)(guan)(guan)夾固定(ding)或膠(jiao)(jiao)管(guan)(guan)(guan)穿(chuan)過(guo)鋼板(ban)等間隔物時，也要(yao)(yao)注意膠(jiao)(jiao)管(guan)(guan)(guan)的(de)外(wai)徑尺(chi)寸。因(yin)此膠(jiao)(jiao)管(guan)(guan)(guan)使(shi)用壽命(ming)長短，不僅決(jue)定(ding)于質(zhi)量的(de)好壞，同(tong)時也決(jue)定(ding)于正確使(shi)用保(bao)養。所以即使(shi)產(chan)品有極高的(de)質(zhi)量，如不能正確地使(shi)用和保(bao)養，也會嚴(yan)重影(ying)響(xiang)(xiang)其(qi)使(shi)用質(zhi)量和壽命(ming)，甚至發生不應有的(de)嚴(yan)重事故(gu)，對財物造成損失。
