膠管內徑要適當(dang)。管(guan)徑過(guo)小會(hui)加大管(guan)路內介質的流速(su)，使(shi)(shi)系(xi)統(tong)發熱(re)，降(jiang)低效率(lv)，而且會(hui)產生過(guo)大的壓力降(jiang)，影響(xiang)整個(ge)系(xi)統(tong)的性能。若膠(jiao)管(guan)采用管(guan)夾固定(ding)或膠(jiao)管(guan)穿過(guo)鋼板(ban)等間隔物時(shi)(shi)，也(ye)要注意膠(jiao)管(guan)的外徑尺寸。因(yin)此膠(jiao)管(guan)使(shi)(shi)用壽命長短，不僅(jin)決(jue)定(ding)于質量(liang)的好(hao)壞(huai)，同(tong)時(shi)(shi)也(ye)決(jue)定(ding)于正(zheng)確使(shi)(shi)用保(bao)養。所以即使(shi)(shi)產品有極高的質量(liang)，如不能正(zheng)確地使(shi)(shi)用和保(bao)養，也(ye)會(hui)嚴重影響(xiang)其使(shi)(shi)用質量(liang)和壽命，甚至發生不應有的嚴重事(shi)故(gu)，對財物造成損失。
