膠管內(nei)徑要適當。管(guan)徑過小會加大管(guan)路內(nei)介質(zhi)(zhi)的流速(su)，使系統(tong)發(fa)熱(re)，降(jiang)低效(xiao)率(lv)，而且會產(chan)生過大的壓力降(jiang)，影響整個系統(tong)的性能。若膠(jiao)管(guan)采用(yong)管(guan)夾固定或膠(jiao)管(guan)穿過鋼(gang)板等間隔(ge)物(wu)時，也要注意(yi)膠(jiao)管(guan)的外(wai)徑尺寸。因此膠(jiao)管(guan)使用(yong)壽命(ming)長短，不僅決(jue)定于質(zhi)(zhi)量(liang)的好壞，同(tong)時也決(jue)定于正確(que)使用(yong)保養。所以即(ji)使產(chan)品有極高的質(zhi)(zhi)量(liang)，如不能正確(que)地使用(yong)和保養，也會嚴重(zhong)影響其(qi)使用(yong)質(zhi)(zhi)量(liang)和壽命(ming)，甚至發(fa)生不應有的嚴重(zhong)事(shi)故，對財(cai)物(wu)造成損失。
