二、軸流風機是送風還是排風
軸流(liu)(liu)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)是(shi)(shi)(shi)通風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)的(de)一種，通風(feng)(feng)(feng)(feng)(feng)(feng)(feng)設(she)備既有送(song)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)設(she)備，也(ye)有排(pai)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)設(she)備，軸流(liu)(liu)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)也(ye)一樣(yang)。以(yi)系統(tong)為中(zhong)心，風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)出(chu)(chu)口(kou)介(jie)質流(liu)(liu)往(wang)系統(tong)，那(nei)就是(shi)(shi)(shi)送(song)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)；風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)出(chu)(chu)口(kou)介(jie)質是(shi)(shi)(shi)從系統(tong)中(zhong)流(liu)(liu)出(chu)(chu)的(de)，那(nei)就是(shi)(shi)(shi)排(pai)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)。一般來說，軸流(liu)(liu)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)的(de)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)向會(hui)用(yong)箭頭(tou)標示(shi)，根據葉(xie)片和旋轉方向就可以(yi)判斷出(chu)(chu)是(shi)(shi)(shi)送(song)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)還是(shi)(shi)(shi)排(pai)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)了(le)；或者在軸流(liu)(liu)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)的(de)出(chu)(chu)口(kou)處貼一片紙片（長度(du)保證在抽風(feng)(feng)(feng)(feng)(feng)(feng)(feng)時(shi)不被吸進去(qu)干擾風(feng)(feng)(feng)(feng)(feng)(feng)(feng)扇(shan)），這樣(yang)你站在下面就可以(yi)看(kan)到風(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)開啟時(shi)到底是(shi)(shi)(shi)送(song)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)還是(shi)(shi)(shi)排(pai)風(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(zhou)流(liu)(liu)風(feng)(feng)機的(de)(de)結構由(you)集流(liu)(liu)器、葉(xie)輪(lun)(lun)、機殼和機軸(zhou)等構成，大型軸(zhou)流(liu)(liu)式(shi)通風(feng)(feng)機還設有整流(liu)(liu)罩(zhao)、導(dao)(dao)流(liu)(liu)葉(xie)片（簡稱(cheng)“導(dao)(dao)葉(xie)”，包括前導(dao)(dao)葉(xie)和后(hou)導(dao)(dao)葉(xie)）、尾部導(dao)(dao)流(liu)(liu)器和擴散筒等，工作(zuo)(zuo)時，具(ju)體(ti)的(de)(de)原理是：當葉(xie)輪(lun)(lun)旋轉時，氣(qi)(qi)體(ti)從集流(liu)(liu)器進(jin)入(ru)葉(xie)輪(lun)(lun)，受到葉(xie)輪(lun)(lun)上葉(xie)片的(de)(de)推擠而使氣(qi)(qi)體(ti)的(de)(de)能(neng)量升高(gao)，然后(hou)流(liu)(liu)入(ru)導(dao)(dao)葉(xie)。導(dao)(dao)葉(xie)將偏轉氣(qi)(qi)流(liu)(liu)變(bian)為(wei)軸(zhou)向流(liu)(liu)動，同時將氣(qi)(qi)體(ti)導(dao)(dao)入(ru)擴壓管，進(jin)一步(bu)將氣(qi)(qi)體(ti)動能(neng)轉換為(wei)壓力(li)能(neng)，最后(hou)引(yin)入(ru)工作(zuo)(zuo)管路。軸(zhou)流(liu)(liu)式(shi)風(feng)(feng)機葉(xie)片的(de)(de)工作(zuo)(zuo)方(fang)式(shi)與(yu)飛(fei)機的(de)(de)機翼類似(si)，但是后(hou)者(zhe)是將升力(li)向上作(zuo)(zuo)用于機翼上并(bing)支撐飛(fei)機的(de)(de)重量，而軸(zhou)流(liu)(liu)式(shi)風(feng)(feng)機則固(gu)定位置(zhi)并(bing)使空氣(qi)(qi)移(yi)動。
