膠管內徑要適當。管(guan)(guan)(guan)徑過(guo)小會(hui)加大(da)管(guan)(guan)(guan)路(lu)內介質(zhi)的(de)流速，使(shi)(shi)系統(tong)發(fa)熱，降低(di)效率，而且(qie)會(hui)產(chan)生過(guo)大(da)的(de)壓力(li)降，影響(xiang)整個系統(tong)的(de)性能。若膠管(guan)(guan)(guan)采(cai)用管(guan)(guan)(guan)夾固定或膠管(guan)(guan)(guan)穿(chuan)過(guo)鋼(gang)板(ban)等間隔物時，也要注意膠管(guan)(guan)(guan)的(de)外(wai)徑尺寸。因此膠管(guan)(guan)(guan)使(shi)(shi)用壽命長短，不僅決(jue)定于(yu)質(zhi)量(liang)的(de)好(hao)壞，同(tong)時也決(jue)定于(yu)正確使(shi)(shi)用保養(yang)。所(suo)以(yi)即使(shi)(shi)產(chan)品有極(ji)高的(de)質(zhi)量(liang)，如不能正確地(di)使(shi)(shi)用和(he)保養(yang)，也會(hui)嚴重影響(xiang)其使(shi)(shi)用質(zhi)量(liang)和(he)壽命，甚至發(fa)生不應有的(de)嚴重事故(gu)，對財物造(zao)成損失。
