膠管內徑要適當。管(guan)(guan)徑過(guo)小會加大管(guan)(guan)路(lu)內介質(zhi)(zhi)的流速，使(shi)系(xi)(xi)統(tong)發熱，降(jiang)低效(xiao)率，而且會產(chan)生(sheng)過(guo)大的壓力降(jiang)，影(ying)響整個系(xi)(xi)統(tong)的性能。若膠管(guan)(guan)采(cai)用(yong)管(guan)(guan)夾固定或膠管(guan)(guan)穿過(guo)鋼板(ban)等間隔物時，也要注(zhu)意膠管(guan)(guan)的外徑尺寸(cun)。因此膠管(guan)(guan)使(shi)用(yong)壽命長短(duan)，不僅決定于(yu)(yu)質(zhi)(zhi)量(liang)的好壞，同時也決定于(yu)(yu)正確使(shi)用(yong)保(bao)(bao)養。所以即使(shi)產(chan)品有極高的質(zhi)(zhi)量(liang)，如不能正確地使(shi)用(yong)和(he)保(bao)(bao)養，也會嚴重影(ying)響其使(shi)用(yong)質(zhi)(zhi)量(liang)和(he)壽命，甚至發生(sheng)不應有的嚴重事故，對財物造成損失(shi)。
