膠管內(nei)徑(jing)要適當(dang)。管(guan)(guan)徑(jing)過小會(hui)(hui)(hui)加大(da)管(guan)(guan)路內(nei)介質的(de)(de)流速(su)，使(shi)(shi)(shi)系統發熱，降(jiang)低(di)效率，而(er)且會(hui)(hui)(hui)產生過大(da)的(de)(de)壓力降(jiang)，影響整個(ge)系統的(de)(de)性能。若膠管(guan)(guan)采(cai)用管(guan)(guan)夾固定(ding)或膠管(guan)(guan)穿過鋼板等(deng)間隔物時，也要注意膠管(guan)(guan)的(de)(de)外(wai)徑(jing)尺寸。因此膠管(guan)(guan)使(shi)(shi)(shi)用壽命長(chang)短，不(bu)僅決(jue)定(ding)于質量的(de)(de)好壞，同時也決(jue)定(ding)于正確使(shi)(shi)(shi)用保(bao)養。所以即(ji)使(shi)(shi)(shi)產品有極高(gao)的(de)(de)質量，如不(bu)能正確地使(shi)(shi)(shi)用和(he)保(bao)養，也會(hui)(hui)(hui)嚴重(zhong)影響其使(shi)(shi)(shi)用質量和(he)壽命，甚至發生不(bu)應(ying)有的(de)(de)嚴重(zhong)事故，對(dui)財物造成損失(shi)。
