二、軸流風機是送風還是排風

軸(zhou)(zhou)流風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)是(shi)通風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)的(de)(de)一種(zhong)，通風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)設備既有送(song)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)設備，也有排(pai)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)設備，軸(zhou)(zhou)流風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)也一樣(yang)。以(yi)系(xi)統(tong)為中心，風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)出口(kou)介(jie)質(zhi)流往系(xi)統(tong)，那就是(shi)送(song)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)；風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)出口(kou)介(jie)質(zhi)是(shi)從系(xi)統(tong)中流出的(de)(de)，那就是(shi)排(pai)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)。一般來說(shuo)，軸(zhou)(zhou)流風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)的(de)(de)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)向(xiang)會用箭頭標示，根據葉片(pian)和旋(xuan)轉方向(xiang)就可以(yi)判斷出是(shi)送(song)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)還(huan)是(shi)排(pai)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)了(le)；或者在(zai)軸(zhou)(zhou)流風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)的(de)(de)出口(kou)處貼一片(pian)紙片(pian)（長度保證(zheng)在(zai)抽風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)時(shi)不被吸進去干擾(rao)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)扇），這樣(yang)你站在(zai)下(xia)面就可以(yi)看到(dao)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)開啟時(shi)到(dao)底是(shi)送(song)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)還(huan)是(shi)排(pai)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)了(le)。

三、軸流風機是干什么用的

軸流風機又叫軸流式風機、局部通風機，是一種氣體平行于風機軸流動的風機，工礦企業常用這種風機，軸流風機的電機和風葉都在一個圓筒里，外形就是一個筒形，用于局部通風，安裝方便，通風換氣效果明顯，常用在流量要求較高而壓力要求較低的場合，起到的是通風換氣或加強散熱的作用。一般軸流風機在冶金、化工、輕工、食品、醫藥設備、機械設備及民用建筑等場所用途較多。如果將軸流風機的外殼去掉的話，也可以用做自由風扇；軸流風機還有一個作用，那就是在較長的排氣管道內間隔串聯安裝，用來提高管道中的風壓。如果您需要購買軸流風機的話，可以先來了解一下軸流風機十大品牌。

四、軸流風機原理是什么

軸流(liu)(liu)風機(ji)(ji)(ji)(ji)的(de)結構由(you)集(ji)流(liu)(liu)器、葉(xie)(xie)(xie)輪(lun)、機(ji)(ji)(ji)(ji)殼和(he)機(ji)(ji)(ji)(ji)軸等構成，大型(xing)軸流(liu)(liu)式通(tong)風機(ji)(ji)(ji)(ji)還(huan)設(she)有整流(liu)(liu)罩、導(dao)(dao)(dao)流(liu)(liu)葉(xie)(xie)(xie)片（簡稱“導(dao)(dao)(dao)葉(xie)(xie)(xie)”，包括前導(dao)(dao)(dao)葉(xie)(xie)(xie)和(he)后(hou)(hou)導(dao)(dao)(dao)葉(xie)(xie)(xie)）、尾部導(dao)(dao)(dao)流(liu)(liu)器和(he)擴(kuo)散(san)筒等，工作(zuo)時，具體(ti)的(de)原(yuan)理(li)是：當葉(xie)(xie)(xie)輪(lun)旋轉時，氣(qi)體(ti)從(cong)集(ji)流(liu)(liu)器進(jin)入葉(xie)(xie)(xie)輪(lun)，受(shou)到葉(xie)(xie)(xie)輪(lun)上葉(xie)(xie)(xie)片的(de)推擠而使氣(qi)體(ti)的(de)能量升高，然(ran)后(hou)(hou)流(liu)(liu)入導(dao)(dao)(dao)葉(xie)(xie)(xie)。導(dao)(dao)(dao)葉(xie)(xie)(xie)將偏轉氣(qi)流(liu)(liu)變為(wei)(wei)軸向流(liu)(liu)動(dong)，同時將氣(qi)體(ti)導(dao)(dao)(dao)入擴(kuo)壓管，進(jin)一步將氣(qi)體(ti)動(dong)能轉換(huan)為(wei)(wei)壓力能，最后(hou)(hou)引入工作(zuo)管路。軸流(liu)(liu)式風機(ji)(ji)(ji)(ji)葉(xie)(xie)(xie)片的(de)工作(zuo)方式與飛機(ji)(ji)(ji)(ji)的(de)機(ji)(ji)(ji)(ji)翼類似(si)，但是后(hou)(hou)者是將升力向上作(zuo)用(yong)于機(ji)(ji)(ji)(ji)翼上并支撐飛機(ji)(ji)(ji)(ji)的(de)重量，而軸流(liu)(liu)式風機(ji)(ji)(ji)(ji)則固(gu)定(ding)位置(zhi)并使空氣(qi)移(yi)動(dong)。
