膠管內徑(jing)(jing)要適當。管徑(jing)(jing)過小會加大管路內介質(zhi)(zhi)(zhi)的流(liu)速，使(shi)(shi)系統(tong)發熱，降低(di)效率，而且(qie)會產(chan)生過大的壓力降，影響整個系統(tong)的性能。若(ruo)膠(jiao)管采用(yong)(yong)管夾固定(ding)或(huo)膠(jiao)管穿過鋼板等間隔物時(shi)，也要注意(yi)膠(jiao)管的外徑(jing)(jing)尺(chi)寸。因(yin)此膠(jiao)管使(shi)(shi)用(yong)(yong)壽命長短(duan)，不僅決定(ding)于(yu)質(zhi)(zhi)(zhi)量(liang)的好(hao)壞，同時(shi)也決定(ding)于(yu)正確使(shi)(shi)用(yong)(yong)保(bao)(bao)養(yang)。所(suo)以即使(shi)(shi)產(chan)品有極高的質(zhi)(zhi)(zhi)量(liang)，如不能正確地使(shi)(shi)用(yong)(yong)和保(bao)(bao)養(yang)，也會嚴重(zhong)影響其使(shi)(shi)用(yong)(yong)質(zhi)(zhi)(zhi)量(liang)和壽命，甚至發生不應有的嚴重(zhong)事(shi)故(gu)，對財物造成(cheng)損失。
