膠管內(nei)徑(jing)要適當。管(guan)(guan)(guan)(guan)徑(jing)過小會加大(da)管(guan)(guan)(guan)(guan)路內(nei)介質(zhi)(zhi)的流速，使系(xi)統發熱，降(jiang)(jiang)低效(xiao)率，而且會產(chan)生(sheng)過大(da)的壓力降(jiang)(jiang)，影(ying)響整個系(xi)統的性能。若膠(jiao)管(guan)(guan)(guan)(guan)采(cai)用(yong)管(guan)(guan)(guan)(guan)夾固定(ding)(ding)或(huo)膠(jiao)管(guan)(guan)(guan)(guan)穿過鋼板(ban)等(deng)間隔物時，也要注意(yi)膠(jiao)管(guan)(guan)(guan)(guan)的外徑(jing)尺寸。因此(ci)膠(jiao)管(guan)(guan)(guan)(guan)使用(yong)壽命長短，不僅決定(ding)(ding)于質(zhi)(zhi)量(liang)的好壞，同時也決定(ding)(ding)于正確使用(yong)保養(yang)(yang)。所(suo)以(yi)即使產(chan)品有極高的質(zhi)(zhi)量(liang)，如不能正確地使用(yong)和保養(yang)(yang)，也會嚴重(zhong)影(ying)響其使用(yong)質(zhi)(zhi)量(liang)和壽命，甚至發生(sheng)不應有的嚴重(zhong)事故，對財物造成損失。
