膠管內徑要適當。管(guan)徑過(guo)小會(hui)加大(da)管(guan)路內介質的(de)(de)流(liu)速，使系統發熱，降低效率，而且會(hui)產(chan)生(sheng)(sheng)過(guo)大(da)的(de)(de)壓(ya)力降，影(ying)響整個系統的(de)(de)性能(neng)。若膠(jiao)管(guan)采用管(guan)夾(jia)固定或膠(jiao)管(guan)穿過(guo)鋼(gang)板等間隔物時，也(ye)要注意(yi)膠(jiao)管(guan)的(de)(de)外(wai)徑尺寸(cun)。因此膠(jiao)管(guan)使用壽命(ming)長短，不僅決(jue)定于質量的(de)(de)好壞，同時也(ye)決(jue)定于正確(que)(que)使用保(bao)養(yang)(yang)。所(suo)以即(ji)使產(chan)品(pin)有極高(gao)的(de)(de)質量，如不能(neng)正確(que)(que)地使用和(he)保(bao)養(yang)(yang)，也(ye)會(hui)嚴重影(ying)響其使用質量和(he)壽命(ming)，甚至發生(sheng)(sheng)不應有的(de)(de)嚴重事故，對財(cai)物造成損失。
