因為離心式通風(feng)機的(de)進口(kou)多(duo)制(zhi)(zhi)(zhi)(zhi)成圓(yuan)形(xing)(xing)(xing)管(guan)，而(er)在通風(feng)管(guan)系中(zhong)，圓(yuan)形(xing)(xing)(xing)管(guan)與(yu)(yu)矩形(xing)(xing)(xing)管(guan)比(bi)較，圓(yuan)形(xing)(xing)(xing)管(guan)占有較大的(de)空間(jian)，同時，圓(yuan)形(xing)(xing)(xing)90°彎(wan)頭比(bi)矩形(xing)(xing)(xing)90°彎(wan)頭制(zhi)(zhi)(zhi)(zhi)作(zuo)(zuo)難度(du)大，技術要(yao)求較高，因此在許多(duo)情(qing)況(kuang)下，把抽風(feng)機的(de)進口(kou)管(guan)制(zhi)(zhi)(zhi)(zhi)成矩形(xing)(xing)(xing)90°彎(wan)頭。為了與(yu)(yu)抽風(feng)機的(de)進口(kou)管(guan)連接(jie)，在圓(yuan)形(xing)(xing)(xing)管(guan)與(yu)(yu)矩形(xing)(xing)(xing)管(guan)之間(jian)制(zhi)(zhi)(zhi)(zhi)作(zuo)(zuo)一個由圓(yuan)形(xing)(xing)(xing)過渡(du)到矩形(xing)(xing)(xing)的(de)過渡(du)接(jie)頭。

出風口接管(guan)(guan)，鍍鋅板(ban)油煙機加工(gong)安裝，離心(xin)通風機的(de)出口管(guan)(guan)，要轉換方(fang)向時(shi)，好與分機中(zhong)(zhong)空(kong)氣的(de)流動(dong)方(fang)向一致，如下圖a所示。當出口管(guan)(guan)接頭長度較(jiao)短，曲率半徑較(jiao)小時(shi)，在彎(wan)頭中(zhong)(zhong)領裝導流板(ban)。
