膠管內徑要適(shi)當。管(guan)徑過(guo)小會加大管(guan)路內介質的(de)(de)流速，使(shi)系統發(fa)熱(re)，降低效率，而(er)且會產(chan)生過(guo)大的(de)(de)壓力(li)降，影響整個系統的(de)(de)性(xing)能(neng)。若膠管(guan)采用管(guan)夾固定(ding)或膠管(guan)穿過(guo)鋼板等間(jian)隔物時，也(ye)(ye)要注意(yi)膠管(guan)的(de)(de)外徑尺寸。因(yin)此(ci)膠管(guan)使(shi)用壽(shou)命(ming)長短(duan)，不(bu)僅決定(ding)于(yu)質量(liang)的(de)(de)好壞，同(tong)時也(ye)(ye)決定(ding)于(yu)正確使(shi)用保養(yang)。所以即(ji)使(shi)產(chan)品有(you)極高(gao)的(de)(de)質量(liang)，如不(bu)能(neng)正確地(di)使(shi)用和(he)保養(yang)，也(ye)(ye)會嚴(yan)(yan)重影響其使(shi)用質量(liang)和(he)壽(shou)命(ming)，甚至發(fa)生不(bu)應(ying)有(you)的(de)(de)嚴(yan)(yan)重事故，對財物造成損(sun)失。
