膠管內徑要適(shi)當。管(guan)(guan)(guan)(guan)徑過小會(hui)加大管(guan)(guan)(guan)(guan)路內介質(zhi)的(de)流(liu)速，使系統發熱(re)，降低(di)效率(lv)，而且會(hui)產(chan)生(sheng)(sheng)過大的(de)壓(ya)力降，影(ying)響整個(ge)系統的(de)性能。若膠(jiao)(jiao)管(guan)(guan)(guan)(guan)采用(yong)(yong)(yong)管(guan)(guan)(guan)(guan)夾固定或膠(jiao)(jiao)管(guan)(guan)(guan)(guan)穿(chuan)過鋼板等間隔(ge)物(wu)時，也要注意膠(jiao)(jiao)管(guan)(guan)(guan)(guan)的(de)外徑尺寸。因(yin)此膠(jiao)(jiao)管(guan)(guan)(guan)(guan)使用(yong)(yong)(yong)壽(shou)命長短，不(bu)僅決定于(yu)質(zhi)量(liang)的(de)好壞，同時也決定于(yu)正確(que)使用(yong)(yong)(yong)保養。所以即(ji)使產(chan)品有(you)極高的(de)質(zhi)量(liang)，如不(bu)能正確(que)地使用(yong)(yong)(yong)和保養，也會(hui)嚴重影(ying)響其使用(yong)(yong)(yong)質(zhi)量(liang)和壽(shou)命，甚至發生(sheng)(sheng)不(bu)應有(you)的(de)嚴重事故，對財物(wu)造成損失。
