膠管內(nei)徑(jing)要(yao)適當。管(guan)徑(jing)過小(xiao)會加大管(guan)路內(nei)介質的(de)流速，使(shi)系(xi)(xi)統(tong)(tong)發(fa)熱，降低效(xiao)率，而且會產生(sheng)過大的(de)壓力降，影響整個系(xi)(xi)統(tong)(tong)的(de)性能。若膠管(guan)采用管(guan)夾固(gu)定或膠管(guan)穿過鋼(gang)板等間隔物時(shi)，也要(yao)注意膠管(guan)的(de)外徑(jing)尺寸(cun)。因(yin)此膠管(guan)使(shi)用壽命長短，不僅決定于(yu)質量(liang)(liang)的(de)好壞，同時(shi)也決定于(yu)正確(que)使(shi)用保(bao)(bao)養(yang)。所以即(ji)使(shi)產品有極高的(de)質量(liang)(liang)，如不能正確(que)地使(shi)用和保(bao)(bao)養(yang)，也會嚴重影響其使(shi)用質量(liang)(liang)和壽命，甚至(zhi)發(fa)生(sheng)不應有的(de)嚴重事故，對財物造成(cheng)損失(shi)。
