膠管內徑(jing)要適(shi)當。管(guan)(guan)徑(jing)過小會加(jia)大管(guan)(guan)路內介質(zhi)的(de)流速，使系統發熱，降(jiang)低效率，而且會產生(sheng)過大的(de)壓(ya)力降(jiang)，影響整個系統的(de)性能(neng)。若膠(jiao)(jiao)管(guan)(guan)采(cai)用管(guan)(guan)夾固定(ding)(ding)或膠(jiao)(jiao)管(guan)(guan)穿過鋼板等間(jian)隔(ge)物時(shi)，也要注(zhu)意(yi)膠(jiao)(jiao)管(guan)(guan)的(de)外(wai)徑(jing)尺(chi)寸。因此膠(jiao)(jiao)管(guan)(guan)使用壽命(ming)長短，不僅決定(ding)(ding)于質(zhi)量(liang)(liang)的(de)好壞，同(tong)時(shi)也決定(ding)(ding)于正確使用保(bao)養。所以即使產品(pin)有(you)極高的(de)質(zhi)量(liang)(liang)，如不能(neng)正確地使用和保(bao)養，也會嚴重影響其使用質(zhi)量(liang)(liang)和壽命(ming)，甚至發生(sheng)不應有(you)的(de)嚴重事故(gu)，對財物造成損失。
