膠管內徑(jing)要(yao)適(shi)當。管(guan)(guan)徑(jing)過(guo)小(xiao)會加大(da)管(guan)(guan)路(lu)內介(jie)質的(de)流速(su)，使(shi)(shi)系(xi)統(tong)發熱，降低效率，而且會產生過(guo)大(da)的(de)壓力降，影響整個系(xi)統(tong)的(de)性能。若膠(jiao)管(guan)(guan)采用(yong)管(guan)(guan)夾(jia)固定或(huo)膠(jiao)管(guan)(guan)穿過(guo)鋼板等間(jian)隔物時(shi)，也要(yao)注意膠(jiao)管(guan)(guan)的(de)外徑(jing)尺寸。因(yin)此(ci)膠(jiao)管(guan)(guan)使(shi)(shi)用(yong)壽命(ming)長短，不(bu)僅(jin)決定于質量(liang)的(de)好壞，同時(shi)也決定于正確使(shi)(shi)用(yong)保(bao)養。所以即使(shi)(shi)產品有極高的(de)質量(liang)，如(ru)不(bu)能正確地使(shi)(shi)用(yong)和保(bao)養，也會嚴重影響其(qi)使(shi)(shi)用(yong)質量(liang)和壽命(ming)，甚至發生不(bu)應(ying)有的(de)嚴重事故(gu)，對財物造成損失。
