膠管內(nei)徑(jing)要(yao)適當。管(guan)徑(jing)過(guo)小會加大(da)管(guan)路內(nei)介質的(de)流速，使系(xi)(xi)統發(fa)(fa)熱，降低效(xiao)率(lv)，而(er)且會產生(sheng)(sheng)過(guo)大(da)的(de)壓力降，影(ying)響整個(ge)系(xi)(xi)統的(de)性能。若膠(jiao)管(guan)采(cai)用(yong)管(guan)夾(jia)固定(ding)或膠(jiao)管(guan)穿過(guo)鋼板等間(jian)隔(ge)物(wu)時，也(ye)要(yao)注(zhu)意膠(jiao)管(guan)的(de)外徑(jing)尺(chi)寸。因此膠(jiao)管(guan)使用(yong)壽命長短，不(bu)僅決定(ding)于質量(liang)的(de)好(hao)壞，同時也(ye)決定(ding)于正確使用(yong)保(bao)養。所以即使產品有(you)極高的(de)質量(liang)，如不(bu)能正確地使用(yong)和(he)保(bao)養，也(ye)會嚴重影(ying)響其使用(yong)質量(liang)和(he)壽命，甚至發(fa)(fa)生(sheng)(sheng)不(bu)應有(you)的(de)嚴重事故，對(dui)財物(wu)造成損失。
