（1）主(zhu)排煙管(guan)道(dao)(dao)通(tong)(tong)風(feng)(feng)面(mian)積(ji)(ji)不夠，氣體(ti)流速(su)過大。根據工程經驗，排煙主(zhu)管(guan)道(dao)(dao)內風(feng)(feng)速(su)不能超過15m/s。否則在運(yun)行(xing)一(yi)個時期以后（如一(yi)年以后）很容易造成排煙系統不通(tong)(tong)暢。在油煙凈化器的(de)運(yun)行(xing)實踐中，大部分案例都是因(yin)排煙管(guan)道(dao)(dao)通(tong)(tong)風(feng)(feng)面(mian)積(ji)(ji)不足(zu)引起的(de)不通(tong)(tong)暢，管(guan)道(dao)(dao)內氣體(ti)的(de)流速(su)都在15m/s以上。

（2）排(pai)煙管道由(you)于要穿過建筑梁(liang)而使管道通風截(jie)面積變小(xiao)，截(jie)面上阻(zu)力(li)增加，造成氣(qi)流(liu)不通暢(chang)。

（3）排煙管(guan)道在穿過建筑梁或躲避其它設備(bei)管(guan)道時，麗江油煙凈化器，排煙管(guan)道中的一段(duan)(duan)會低于(yu)整體排煙管(guan)道平面。在使用一段(duan)(duan)時間后，由于(yu)油水混合物會積聚在較(jiao)低的那段(duan)(duan)排煙管(guan)道中，直接影響排煙通暢。

（4）不(bu)同(tong)樓(lou)層的廚房油煙(yan)通(tong)過同(tong)一(yi)主管(guan)道排(pai)出，離(li)出口(kou)近的樓(lou)層廚房排(pai)煙(yan)效果較好，而較低樓(lou)層的廚房排(pai)煙(yan)不(bu)通(tong)暢。
