一、軸流風機和離心式風機的區別在哪里
1、排(pai)(pai)(pai)(pai)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)方(fang)向不同:軸(zhou)(zhou)(zhou)(zhou)流風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)(ji)的(de)(de)(de)排(pai)(pai)(pai)(pai)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)方(fang)向是(shi)(shi)沿著軸(zhou)(zhou)(zhou)(zhou)的(de)(de)(de)方(fang)向直(zhi)排(pai)(pai)(pai)(pai),風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)(ji)的(de)(de)(de)進(jin)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)口和(he)(he)排(pai)(pai)(pai)(pai)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)口是(shi)(shi)在一(yi)(yi)條軸(zhou)(zhou)(zhou)(zhou)平(ping)行線上,離(li)心(xin)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)(ji)的(de)(de)(de)排(pai)(pai)(pai)(pai)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)方(fang)向是(shi)(shi)垂直(zhi)于進(jin)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)口方(fang)向的(de)(de)(de),可以實現360度指定(ding)(ding)方(fang)向排(pai)(pai)(pai)(pai)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)。2、安(an)裝(zhuang)難度程度不同:軸(zhou)(zhou)(zhou)(zhou)流風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)(ji)的(de)(de)(de)安(an)裝(zhuang)比(bi)較簡單,一(yi)(yi)般(ban)是(shi)(shi)直(zhi)接(jie)安(an)裝(zhuang)在墻(qiang)上或(huo)者連(lian)接(jie)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)管。離(li)心(xin)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)(ji)安(an)裝(zhuang)比(bi)較復雜,安(an)裝(zhuang)時,軸(zhou)(zhou)(zhou)(zhou)承(cheng)座(zuo)(zuo)與底座(zuo)(zuo)必須要緊密接(jie)合,底座(zuo)(zuo)上的(de)(de)(de)切削(xue)加(jia)工面應妥善保護(hu),不應有(you)銹蝕(shi)或(huo)操作。風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)(ji)找(zhao)正時,徑向定(ding)(ding)位(wei)移不應超過0.05毫米(mi)。3、風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)量和(he)(he)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)壓(ya)的(de)(de)(de)不同:軸(zhou)(zhou)(zhou)(zhou)流風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)(ji)的(de)(de)(de)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)量風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)壓(ya)比(bi)較小(xiao),基(ji)本上沒什么風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)壓(ya),而離(li)心(xin)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)(ji)的(de)(de)(de)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)量風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)壓(ya)都(dou)比(bi)較大,如果是(shi)(shi)管道彎頭多,抽(chou)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)距離(li)和(he)(he)送風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)距離(li)都(dou)比(bi)較遠,管道阻力(li)大,就(jiu)一(yi)(yi)定(ding)(ding)使用離(li)心(xin)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)(ji)。4、外(wai)(wai)觀形狀不同:軸(zhou)(zhou)(zhou)(zhou)流風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)(ji)外(wai)(wai)觀基(ji)本上呈圓筒狀,離(li)心(xin)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)(ji)的(de)(de)(de)外(wai)(wai)觀呈蝸(gua)牛狀。5、風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)(ji)的(de)(de)(de)電(dian)機(ji)(ji)(ji)連(lian)接(jie)方(fang)式不同:軸(zhou)(zhou)(zhou)(zhou)流風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)(ji)的(de)(de)(de)電(dian)機(ji)(ji)(ji)連(lian)接(jie)一(yi)(yi)般(ban)都(dou)是(shi)(shi)在風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)(ji)的(de)(de)(de)機(ji)(ji)(ji)體(ti)內,離(li)心(xin)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)(ji)的(de)(de)(de)電(dian)機(ji)(ji)(ji)都(dou)是(shi)(shi)靠軸(zhou)(zhou)(zhou)(zhou)連(lian)接(jie),一(yi)(yi)般(ban)是(shi)(shi)外(wai)(wai)置(zhi)在風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)(ji)抽(chou)風(feng)(feng)(feng)(feng)(feng)(feng)(feng)(feng)筒外(wai)(wai)。
二、軸流風機是送風還是排風
軸(zhou)流(liu)(liu)風(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)是通風(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)的一種,通風(feng)(feng)(feng)(feng)(feng)(feng)設(she)備既有送(song)(song)(song)風(feng)(feng)(feng)(feng)(feng)(feng)設(she)備,也有排風(feng)(feng)(feng)(feng)(feng)(feng)設(she)備,軸(zhou)流(liu)(liu)風(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)也一樣(yang)。以系統為中心,風(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)出口(kou)介(jie)質(zhi)流(liu)(liu)往系統,那就(jiu)(jiu)是送(song)(song)(song)風(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji);風(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)出口(kou)介(jie)質(zhi)是從系統中流(liu)(liu)出的,那就(jiu)(jiu)是排風(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)。一般來(lai)說(shuo),軸(zhou)流(liu)(liu)風(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)的風(feng)(feng)(feng)(feng)(feng)(feng)向(xiang)會用箭頭標示,根據葉片和旋(xuan)轉方(fang)向(xiang)就(jiu)(jiu)可(ke)以判(pan)斷出是送(song)(song)(song)風(feng)(feng)(feng)(feng)(feng)(feng)還是排風(feng)(feng)(feng)(feng)(feng)(feng)了;或(huo)者(zhe)在(zai)(zai)軸(zhou)流(liu)(liu)風(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)的出口(kou)處貼一片紙(zhi)片(長(chang)度保證在(zai)(zai)抽風(feng)(feng)(feng)(feng)(feng)(feng)時不被吸進去干擾風(feng)(feng)(feng)(feng)(feng)(feng)扇),這樣(yang)你站在(zai)(zai)下面(mian)就(jiu)(jiu)可(ke)以看(kan)到(dao)風(feng)(feng)(feng)(feng)(feng)(feng)機(ji)(ji)開啟(qi)時到(dao)底是送(song)(song)(song)風(feng)(feng)(feng)(feng)(feng)(feng)還是排風(feng)(feng)(feng)(feng)(feng)(feng)了。
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)風機(ji)的(de)(de)結構由集(ji)流(liu)器、葉(xie)輪、機(ji)殼和機(ji)軸(zhou)等(deng)構成(cheng),大型軸(zhou)流(liu)式通風機(ji)還設有(you)整(zheng)流(liu)罩、導(dao)(dao)(dao)流(liu)葉(xie)片(pian)(簡稱“導(dao)(dao)(dao)葉(xie)”,包括前導(dao)(dao)(dao)葉(xie)和后(hou)(hou)導(dao)(dao)(dao)葉(xie))、尾部導(dao)(dao)(dao)流(liu)器和擴散(san)筒等(deng),工(gong)作(zuo)(zuo)時,具體的(de)(de)原理是:當(dang)葉(xie)輪旋轉(zhuan)時,氣體從集(ji)流(liu)器進(jin)入(ru)(ru)(ru)葉(xie)輪,受到(dao)葉(xie)輪上葉(xie)片(pian)的(de)(de)推(tui)擠而(er)使(shi)氣體的(de)(de)能(neng)量(liang)升高,然(ran)后(hou)(hou)流(liu)入(ru)(ru)(ru)導(dao)(dao)(dao)葉(xie)。導(dao)(dao)(dao)葉(xie)將(jiang)偏轉(zhuan)氣流(liu)變為軸(zhou)向流(liu)動,同時將(jiang)氣體導(dao)(dao)(dao)入(ru)(ru)(ru)擴壓(ya)管,進(jin)一步將(jiang)氣體動能(neng)轉(zhuan)換為壓(ya)力能(neng),最后(hou)(hou)引入(ru)(ru)(ru)工(gong)作(zuo)(zuo)管路。軸(zhou)流(liu)式風機(ji)葉(xie)片(pian)的(de)(de)工(gong)作(zuo)(zuo)方式與飛機(ji)的(de)(de)機(ji)翼類似,但是后(hou)(hou)者是將(jiang)升力向上作(zuo)(zuo)用于機(ji)翼上并支撐飛機(ji)的(de)(de)重(zhong)量(liang),而(er)軸(zhou)流(liu)式風機(ji)則固定位置并使(shi)空氣移動。
