南岸值得信賴的風機廠家

在(zai)(zai)空(kong)調(diao)送(song)風系(xi)統中(zhong)，空(kong)調(diao)送(song)風機(ji)送(song)出的(de)(de)風必須通(tong)(tong)過主干(gan)(gan)管(guan)分配到支管(guan)中(zhong)；在(zai)(zai)排(pai)(pai)煙(yan)(yan)(yan)(yan)系(xi)統中(zhong)，煙(yan)(yan)(yan)(yan)氣(qi)由(you)支管(guan)到主干(gan)(gan)管(guan)后，進入排(pai)(pai)煙(yan)(yan)(yan)(yan)風機(ji)排(pai)(pai)出。當建筑物內(nei)發生(sheng)火(huo)(huo)(huo)災時，在(zai)(zai)通(tong)(tong)風、空(kong)調(diao)系(xi)統中(zhong)，為了(le)防止(zhi)火(huo)(huo)(huo)勢通(tong)(tong)過送(song)風系(xi)統蔓延，當送(song)風系(xi)統中(zhong)氣(qi)體溫(wen)度達(da)(da)到70℃時，防火(huo)(huo)(huo)閥機(ji)構(gou)上熔(rong)斷(duan)器(qi)動(dong)作，閥門亦迅速(su)關閥，切斷(duan)煙(yan)(yan)(yan)(yan)氣(qi)與火(huo)(huo)(huo)勢沿風管(guan)蔓延的(de)(de)通(tong)(tong)路。同(tong)樣，在(zai)(zai)排(pai)(pai)煙(yan)(yan)(yan)(yan)系(xi)統中(zhong)，發生(sheng)火(huo)(huo)(huo)災時，排(pai)(pai)煙(yan)(yan)(yan)(yan)閥開啟(qi)，進行排(pai)(pai)煙(yan)(yan)(yan)(yan)，為了(le)截斷(duan)高溫(wen)煙(yan)(yan)(yan)(yan)氣(qi)在(zai)(zai)排(pai)(pai)煙(yan)(yan)(yan)(yan)管(guan)路中(zhong)流動(dong)，防止(zhi)火(huo)(huo)(huo)勢蔓延到另(ling)一防火(huo)(huo)(huo)分區，當排(pai)(pai)出的(de)(de)煙(yan)(yan)(yan)(yan)氣(qi)溫(wen)度達(da)(da)到280℃時，排(pai)(pai)煙(yan)(yan)(yan)(yan)防火(huo)(huo)(huo)閥、排(pai)(pai)煙(yan)(yan)(yan)(yan)口上熔(rong)斷(duan)器(qi)動(dong)作，閥門必須自動(dong)關閉，阻止(zhi)排(pai)(pai)煙(yan)(yan)(yan)(yan)。由(you)此可見，防火(huo)(huo)(huo)閥、排(pai)(pai)煙(yan)(yan)(yan)(yan)閥做到了(le)該通(tong)(tong)則(ze)通(tong)(tong)，該斷(duan)則(ze)斷(duan)的(de)(de)隔(ge)煙(yan)(yan)(yan)(yan)阻火(huo)(huo)(huo)作用(yong)。

鑒于軸流(liu)風(feng)(feng)(feng)機(ji)有紊流(liu)區(qu)(qu)的(de)(de)性能特點，在(zai)選(xuan)型和(he)使用(yong)時，需要注(zhu)意(yi)以下兩點：建議(yi)使用(yong)在(zai)空(kong)曠(kuang)環(huan)境(jing)中(zhong),軸流(liu)風(feng)(feng)(feng)機(ji)的(de)(de)輸入功(gong)率隨系(xi)統靜壓的(de)(de)增(zeng)(zeng)大(da)而(er)(er)增(zeng)(zeng)大(da)，而(er)(er)在(zai)紊流(liu)區(qu)(qu)，輸入功(gong)率的(de)(de)增(zeng)(zeng)大(da)幅度會(hui)(hui)更大(da)。因此，軸流(liu)風(feng)(feng)(feng)機(ji)一般多(duo)(duo)應用(yong)在(zai)有較(jiao)(jiao)大(da)空(kong)曠(kuang)環(huan)境(jing)的(de)(de)場合下，可以使其(qi)工(gong)作在(zai)靜壓較(jiao)(jiao)低的(de)(de)環(huan)境(jing)下，降低功(gong)耗，保(bao)證穩定(ding)性和(he)壽命。定(ding)期清(qing)理(li)風(feng)(feng)(feng)道,當軸流(liu)風(feng)(feng)(feng)機(ji)應用(yong)在(zai)較(jiao)(jiao)為(wei)封閉的(de)(de)風(feng)(feng)(feng)道系(xi)統中(zhong)時，長(chang)期運行(xing)后風(feng)(feng)(feng)道中(zhong)的(de)(de)積灰、垃圾逐漸變多(duo)(duo)，會(hui)(hui)使風(feng)(feng)(feng)道內的(de)(de)靜壓逐漸增(zeng)(zeng)加(jia)，使得風(feng)(feng)(feng)機(ji)的(de)(de)運行(xing)工(gong)況點逐漸左移。這不僅會(hui)(hui)降低風(feng)(feng)(feng)機(ji)性能，更重要的(de)(de)是會(hui)(hui)增(zeng)(zeng)加(jia)軸流(liu)風(feng)(feng)(feng)機(ji)進入紊流(liu)區(qu)(qu)的(de)(de)風(feng)(feng)(feng)險。因此必須(xu)要定(ding)期清(qing)理(li)風(feng)(feng)(feng)道，保(bao)證風(feng)(feng)(feng)機(ji)工(gong)況點不產生較(jiao)(jiao)大(da)偏移。

消(xiao)防(fang)(fang)排(pai)(pai)煙(yan)(yan)機(ji)(ji)(ji)一(yi)(yi)般(ban)是(shi)采(cai)用離心式(shi)(shi)(shi)風(feng)機(ji)(ji)(ji)和軸流(liu)(liu)式(shi)(shi)(shi)風(feng)機(ji)(ji)(ji)兩種(zhong)重要的(de)(de)(de)(de)型(xing)(xing)式(shi)(shi)(shi)。從消(xiao)防(fang)(fang)排(pai)(pai)煙(yan)(yan)風(feng)機(ji)(ji)(ji)風(feng)量、風(feng)壓(ya)考慮來看，消(xiao)防(fang)(fang)排(pai)(pai)煙(yan)(yan)風(feng)機(ji)(ji)(ji)是(shi)高(gao)比轉高(gao)效率的(de)(de)(de)(de)風(feng)機(ji)(ji)(ji)，更(geng)加的(de)(de)(de)(de)適合選用軸流(liu)(liu)風(feng)機(ji)(ji)(ji)。軸流(liu)(liu)式(shi)(shi)(shi)消(xiao)防(fang)(fang)排(pai)(pai)煙(yan)(yan)風(feng)機(ji)(ji)(ji)有兩種(zhong)設計型(xing)(xing)式(shi)(shi)(shi)，一(yi)(yi)種(zhong)為(wei)電機(ji)(ji)(ji)與(yu)主(zhu)氣流(liu)(liu)分離型(xing)(xing)式(shi)(shi)(shi)，另一(yi)(yi)種(zhong)為(wei)電機(ji)(ji)(ji)置于(yu)主(zhu)氣流(liu)(liu)之中。根(gen)據煙(yan)(yan)氣溫度(du)(du)的(de)(de)(de)(de)不(bu)同，采(cai)用不(bu)同型(xing)(xing)式(shi)(shi)(shi)的(de)(de)(de)(de)消(xiao)防(fang)(fang)排(pai)(pai)煙(yan)(yan)風(feng)機(ji)(ji)(ji)，溫度(du)(du)大于(yu)400℃時，采(cai)用電機(ji)(ji)(ji)與(yu)主(zhu)氣流(liu)(liu)分離型(xing)(xing)式(shi)(shi)(shi)，溫度(du)(du)小(xiao)于(yu)400℃大于(yu)150℃，兩種(zhong)型(xing)(xing)式(shi)(shi)(shi)的(de)(de)(de)(de)電機(ji)(ji)(ji)都可以選擇，在溫度(du)(du)小(xiao)于(yu)150℃的(de)(de)(de)(de)時候，采(cai)用電機(ji)(ji)(ji)置于(yu)主(zhu)氣流(liu)(liu)之中。 軸流(liu)(liu)消(xiao)防(fang)(fang)排(pai)(pai)煙(yan)(yan)風(feng)機(ji)(ji)(ji)的(de)(de)(de)(de)流(liu)(liu)量范圍(wei)從7200m？/h至110000m？/h，有不(bu)同型(xing)(xing)號的(de)(de)(de)(de)編制，用來滿足不(bu)同通風(feng)排(pai)(pai)煙(yan)(yan)流(liu)(liu)量的(de)(de)(de)(de)需求。消(xiao)防(fang)(fang)排(pai)(pai)煙(yan)(yan)風(feng)機(ji)(ji)(ji)可以根(gen)據壓(ya)力(li)情況的(de)(de)(de)(de)不(bu)同分為(wei)兩種(zhong)類型(xing)(xing)，一(yi)(yi)類為(wei)軸流(liu)(liu)式(shi)(shi)(shi)消(xiao)防(fang)(fang)排(pai)(pai)煙(yan)(yan)機(ji)(ji)(ji)，其各機(ji)(ji)(ji)號的(de)(de)(de)(de)壓(ya)力(li)在600Pa左(zuo)右(you)，另一(yi)(yi)類為(wei)斜流(liu)(liu)消(xiao)防(fang)(fang)排(pai)(pai)煙(yan)(yan)風(feng)機(ji)(ji)(ji)，各機(ji)(ji)(ji)號的(de)(de)(de)(de)壓(ya)力(li)在1000Pa左(zuo)右(you)。為(wei)了滿足排(pai)(pai)煙(yan)(yan)量和通風(feng)換氣的(de)(de)(de)(de)要求，消(xiao)防(fang)(fang)排(pai)(pai)煙(yan)(yan)風(feng)機(ji)(ji)(ji)一(yi)(yi)般(ban)都設計了雙速型(xing)(xing)的(de)(de)(de)(de)結(jie)構模式(shi)(shi)(shi)。低速可以通風(feng)使用，高(gao)速可以排(pai)(pai)放(fang)煙(yan)(yan)霧，這樣(yang)不(bu)但可以節(jie)約能源(yuan)同時又降低了噪聲污染。

1) 送風(feng)(feng)(feng)，包括通氣，如(ru)(ru)送鮮風(feng)(feng)(feng)和排(pai)氣，這個范圍(wei)很(hen)廣(guang)，如(ru)(ru)工(gong)(gong)廠(chang)車(che)間(jian)，生產場地空(kong)氣，由于有(you)(you)害(hai)氣體產生需要(yao)排(pai)出室外，又需要(yao)把室外空(kong)氣輸(shu)送至室內。這時就要(yao)使(shi)(shi)用(yong)(yong)(yong)流(liu)量大而壓力小的(de)空(kong)氣輸(shu)送管(guan)(guan)(guan)(guan)道(dao)，螺(luo)(luo)旋(xuan)(xuan)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)就適用(yong)(yong)(yong)，一(yi)般情(qing)況下使(shi)(shi)用(yong)(yong)(yong)鍍鋅鐵管(guan)(guan)(guan)(guan)，有(you)(you)腐蝕性及特(te)別(bie)潮(chao)濕場所使(shi)(shi)用(yong)(yong)(yong)不銹鋼管(guan)(guan)(guan)(guan)。2) 送冷風(feng)(feng)(feng)。常見的(de)是(shi)(shi)中央空(kong)調的(de)管(guan)(guan)(guan)(guan)道(dao)，這種管(guan)(guan)(guan)(guan)道(dao)需要(yao)加保溫材(cai)料。螺(luo)(luo)旋(xuan)(xuan)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)可(ke)內貼保溫材(cai)料，外表看來美觀。3) 排(pai)油(you)煙。飯(fan)店、酒(jiu)樓、賓館的(de)廚房均有(you)(you)大量油(you)煙產生，需要(yao)排(pai)出，使(shi)(shi)用(yong)(yong)(yong)圓(yuan)形(xing)的(de)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)就是(shi)(shi)油(you)煙囪。在這里，螺(luo)(luo)旋(xuan)(xuan)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)該(gai)叫做油(you)煙管(guan)(guan)(guan)(guan)。4) 除塵。有(you)(you)些工(gong)(gong)廠(chang)生產車(che)間(jian)很(hen)多(duo)塵埃，需要(yao)專門的(de)除塵裝(zhuang)置，其中量較大的(de)管(guan)(guan)(guan)(guan)道(dao)，可(ke)使(shi)(shi)用(yong)(yong)(yong)螺(luo)(luo)旋(xuan)(xuan)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)。5) 散裝(zhuang)物料輸(shu)送。有(you)(you)些工(gong)(gong)廠(chang)的(de)生產過程(cheng)中，需要(yao)輸(shu)送松散的(de)顆粒(li)，特(te)別(bie)是(shi)(shi)比(bi)重不大的(de)如(ru)(ru)發泡(pao)塑料粒(li)之類的(de)使(shi)(shi)用(yong)(yong)(yong)螺(luo)(luo)旋(xuan)(xuan)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)造價(jia)低、效果好。

防火閥是用來阻斷來自火災區的煙氣及火焰通過，并在一定時間內能滿足耐火穩定性和耐火完整性要求的閥門。南岸風機為了將火災引起的損失減少到小程度，就必須采取有效的防火、防排煙措施，以控制火勢蔓延，而防火閥在通風、空調及防排煙系統中的合理設置，則風機起到了重要(yao)(yao)的作(zuo)用。防(fang)火閥(fa)的結構和(he)工作(zuo)原理,防(fang)火閥(fa)主要(yao)(yao)由(you)閥(fa)體(ti)和(he)執(zhi)行機構組成(cheng)。閥(fa)體(ti)由(you)殼體(ti)、法(fa)蘭、葉片及葉片聯動(dong)機構等組成(cheng)。執(zhi)行機構由(you)外殼、葉片調節機構、離(li)合(he)器、溫度熔斷器等組成(cheng)。防(fang)火閥(fa)的執(zhi)行機構是通過金(jin)屬易熔片和(he)離(li)合(he)器機構來控制葉片的轉動(dong)。
