膠管內徑要適當。管(guan)(guan)(guan)徑過(guo)小會加大(da)管(guan)(guan)(guan)路內介質(zhi)的(de)(de)(de)(de)流速，使(shi)系(xi)統(tong)發(fa)熱，降(jiang)低效率，而(er)且會產生過(guo)大(da)的(de)(de)(de)(de)壓力降(jiang)，影響整個(ge)系(xi)統(tong)的(de)(de)(de)(de)性能。若(ruo)膠管(guan)(guan)(guan)采用(yong)管(guan)(guan)(guan)夾固(gu)定(ding)或膠管(guan)(guan)(guan)穿過(guo)鋼板等間隔物時，也要注意膠管(guan)(guan)(guan)的(de)(de)(de)(de)外徑尺寸。因此膠管(guan)(guan)(guan)使(shi)用(yong)壽命長短(duan)，不僅決(jue)定(ding)于質(zhi)量的(de)(de)(de)(de)好壞，同時也決(jue)定(ding)于正確(que)使(shi)用(yong)保養(yang)。所以(yi)即(ji)使(shi)產品有(you)極高的(de)(de)(de)(de)質(zhi)量，如不能正確(que)地使(shi)用(yong)和保養(yang)，也會嚴重影響其使(shi)用(yong)質(zhi)量和壽命，甚至發(fa)生不應有(you)的(de)(de)(de)(de)嚴重事故，對(dui)財物造成(cheng)損(sun)失。
