膠管內(nei)徑要適當。管徑過(guo)(guo)小會加(jia)大管路內(nei)介(jie)質(zhi)(zhi)的(de)(de)流速，使(shi)(shi)系統發(fa)熱，降(jiang)低效率，而(er)且會產(chan)(chan)生過(guo)(guo)大的(de)(de)壓力降(jiang)，影(ying)響(xiang)(xiang)整個系統的(de)(de)性能。若(ruo)膠(jiao)管采用(yong)管夾(jia)固定(ding)(ding)或膠(jiao)管穿過(guo)(guo)鋼板等(deng)間隔物時，也要注意(yi)膠(jiao)管的(de)(de)外徑尺寸。因此膠(jiao)管使(shi)(shi)用(yong)壽(shou)命長(chang)短，不(bu)僅(jin)決定(ding)(ding)于(yu)質(zhi)(zhi)量的(de)(de)好壞，同時也決定(ding)(ding)于(yu)正(zheng)確(que)使(shi)(shi)用(yong)保(bao)養。所(suo)以即使(shi)(shi)產(chan)(chan)品有極高的(de)(de)質(zhi)(zhi)量，如不(bu)能正(zheng)確(que)地(di)使(shi)(shi)用(yong)和保(bao)養，也會嚴重影(ying)響(xiang)(xiang)其使(shi)(shi)用(yong)質(zhi)(zhi)量和壽(shou)命，甚至發(fa)生不(bu)應(ying)有的(de)(de)嚴重事故，對財(cai)物造成損失。
