膠管內徑要(yao)適當。管(guan)(guan)(guan)徑過小會加大管(guan)(guan)(guan)路內介質的(de)(de)流速，使(shi)系統發熱(re)，降低效(xiao)率，而(er)且會產生過大的(de)(de)壓力降，影(ying)響整個系統的(de)(de)性(xing)能。若(ruo)膠(jiao)管(guan)(guan)(guan)采(cai)用管(guan)(guan)(guan)夾固定或膠(jiao)管(guan)(guan)(guan)穿(chuan)過鋼板等間隔物時，也要(yao)注意膠(jiao)管(guan)(guan)(guan)的(de)(de)外徑尺寸。因此膠(jiao)管(guan)(guan)(guan)使(shi)用壽命長(chang)短，不僅決(jue)定于(yu)質量(liang)的(de)(de)好壞，同時也決(jue)定于(yu)正確使(shi)用保(bao)養。所(suo)以(yi)即使(shi)產品有極高的(de)(de)質量(liang)，如不能正確地使(shi)用和(he)保(bao)養，也會嚴(yan)重影(ying)響其(qi)使(shi)用質量(liang)和(he)壽命，甚(shen)至發生不應有的(de)(de)嚴(yan)重事故，對(dui)財物造成損失。
