廚房排煙管道好的消防排煙風管的設計和安裝不合理，往往會造成廚房排煙不通暢，直接影響油煙凈化器的使用，其主要消防排煙風管定制原因有以下幾(ji)種： 一(yi)、主(zhu)排(pai)(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)管(guan)(guan)(guan)(guan)道(dao)(dao)通(tong)風(feng)(feng)(feng)(feng)(feng)面(mian)(mian)積(ji)不(bu)(bu)(bu)(bu)夠(gou) 迅(xun)速(su)排(pai)(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)防止串(chuan)(chuan)味(wei)看廚(chu)房(fang)排(pai)(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)管(guan)(guan)(guan)(guan)道(dao)(dao)安(an)裝(zhuang) 根據工程經驗，排(pai)(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)主(zhu)管(guan)(guan)(guan)(guan)道(dao)(dao)內風(feng)(feng)(feng)(feng)(feng)速(su)不(bu)(bu)(bu)(bu)能(neng)超過(guo)15m/s，否則在(zai)運行(xing)(xing)一(yi)個時(shi)(shi)期以后很(hen)容易(yi)造成(cheng)排(pai)(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)系統不(bu)(bu)(bu)(bu)通(tong)暢。在(zai)油(you)(you)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)凈化(hua)器(qi)的(de)運行(xing)(xing)實踐中(zhong)，大(da)部分案例都(dou)是因排(pai)(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)管(guan)(guan)(guan)(guan)道(dao)(dao)通(tong)風(feng)(feng)(feng)(feng)(feng)面(mian)(mian)積(ji)不(bu)(bu)(bu)(bu)足引(yin)起(qi)的(de)不(bu)(bu)(bu)(bu)通(tong)暢，管(guan)(guan)(guan)(guan)道(dao)(dao)內氣體的(de)流(liu)(liu)速(su)都(dou)在(zai)15m/s以上(shang)(shang)。 二(er)、管(guan)(guan)(guan)(guan)道(dao)(dao)截面(mian)(mian)積(ji)變小(xiao) 迅(xun)速(su)排(pai)(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)防止串(chuan)(chuan)味(wei) 看廚(chu)房(fang)排(pai)(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)管(guan)(guan)(guan)(guan)道(dao)(dao)安(an)裝(zhuang) 排(pai)(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)管(guan)(guan)(guan)(guan)道(dao)(dao)由于要(yao)穿過(guo)建筑梁而使管(guan)(guan)(guan)(guan)道(dao)(dao)通(tong)風(feng)(feng)(feng)(feng)(feng)截面(mian)(mian)積(ji)變小(xiao)，截面(mian)(mian)上(shang)(shang)阻力(li)增加，造成(cheng)氣流(liu)(liu)不(bu)(bu)(bu)(bu)通(tong)暢。 三、排(pai)(pai)(pai)(pai)(pai)(pai)(pai)管(guan)(guan)(guan)(guan)道(dao)(dao)使用(yong)后積(ji)聚(ju)物堆積(ji) 迅(xun)速(su)排(pai)(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)防止串(chuan)(chuan)味(wei) 看廚(chu)房(fang)排(pai)(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)管(guan)(guan)(guan)(guan)道(dao)(dao)安(an)裝(zhuang) 排(pai)(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)管(guan)(guan)(guan)(guan)道(dao)(dao)在(zai)穿過(guo)建筑梁或(huo)躲避(bi)其它(ta)設備管(guan)(guan)(guan)(guan)道(dao)(dao)時(shi)(shi)，排(pai)(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)管(guan)(guan)(guan)(guan)道(dao)(dao)中(zhong)的(de)一(yi)段會(hui)低(di)(di)于整體排(pai)(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)管(guan)(guan)(guan)(guan)道(dao)(dao)平面(mian)(mian)，在(zai)使用(yong)一(yi)段時(shi)(shi)間后，由于油(you)(you)水(shui)混合物會(hui)積(ji)聚(ju)在(zai)較(jiao)(jiao)低(di)(di)的(de)那(nei)段排(pai)(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)管(guan)(guan)(guan)(guan)道(dao)(dao)中(zhong)，直接(jie)影響(xiang)排(pai)(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)通(tong)暢。 四、低(di)(di)層(ceng)排(pai)(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)不(bu)(bu)(bu)(bu)順暢 不(bu)(bu)(bu)(bu)同樓層(ceng)的(de)廚(chu)房(fang)油(you)(you)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)通(tong)過(guo)同一(yi)主(zhu)管(guan)(guan)(guan)(guan)道(dao)(dao)排(pai)(pai)(pai)(pai)(pai)(pai)(pai)出(chu)，離(li)出(chu)口近(jin)的(de)樓層(ceng)廚(chu)房(fang)排(pai)(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)效果(guo)較(jiao)(jiao)好，而較(jiao)(jiao)低(di)(di)樓層(ceng)的(de)廚(chu)房(fang)排(pai)(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)不(bu)(bu)(bu)(bu)通(tong)暢。 五、建議配(pei)備排(pai)(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)風(feng)(feng)(feng)(feng)(feng)機(ji) 對于油(you)(you)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)較(jiao)(jiao)大(da)的(de)廚(chu)房(fang)，建議還配(pei)備一(yi)個排(pai)(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)風(feng)(feng)(feng)(feng)(feng)機(ji)。常用(yong)的(de)排(pai)(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)風(feng)(feng)(feng)(feng)(feng)機(ji)有軸流(liu)(liu)風(feng)(feng)(feng)(feng)(feng)機(ji)、風(feng)(feng)(feng)(feng)(feng)機(ji)箱和離(li)心(xin)風(feng)(feng)(feng)(feng)(feng)機(ji)3種。 軸流(liu)(liu)風(feng)(feng)(feng)(feng)(feng)機(ji)：以前應用(yong)較(jiao)(jiao)多，但由于全(quan)壓(ya)小(xiao)，在(zai)安(an)裝(zhuang)油(you)(you)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)凈化(hua)器(qi)后很(hen)少(shao)應用(yong)。 風(feng)(feng)(feng)(feng)(feng)機(ji)箱：全(quan)壓(ya)中(zhong)等，風(feng)(feng)(feng)(feng)(feng)量(liang)可(ke)以調節，且(qie)噪(zao)聲(sheng)較(jiao)(jiao)低(di)(di)，常在(zai)集(ji)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)罩距(ju)油(you)(you)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)排(pai)(pai)(pai)(pai)(pai)(pai)(pai)放口距(ju)離(li)中(zhong)等的(de)廚(chu)房(fang)排(pai)(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)系統中(zhong)選(xuan)用(yong)。 離(li)心(xin)風(feng)(feng)(feng)(feng)(feng)機(ji)：全(quan)壓(ya)和風(feng)(feng)(feng)(feng)(feng)量(liang)都(dou)可(ke)以調節，但由于噪(zao)聲(sheng)較(jiao)(jiao)大(da)，常需要(yao)做降噪(zao)處理(li)。當廚(chu)房(fang)位于建筑物的(de)底部時(shi)(shi)其排(pai)(pai)(pai)(pai)(pai)(pai)(pai)風(feng)(feng)(feng)(feng)(feng)機(ji)宜安(an)放在(zai)屋頂，一(yi)般選(xuan)擇離(li)心(xin)風(feng)(feng)(feng)(feng)(feng)機(ji)。

工業中的好的消防排煙風管主要有： (1)白鐵管道類：白消防排煙風管定制鐵(tie)厚鐵(tie)各(ge)種排氣(qi)(qi)，排風、吸塵管(guan)道(dao)，中(zhong)央空(kong)調冷(leng)氣(qi)(qi)管(guan)，廚(chu)房(fang)抽(chou)油煙管(guan)道(dao)，保溫(wen)管(guan)、烤(kao)漆(qi)爐(lu)抽(chou)煙煙罩。 (2)白(bai)(bai)(bai)鐵(tie)工(gong)(gong)程(cheng)(cheng)類：酒(jiu)店餐館超(chao)市工(gong)(gong)程(cheng)(cheng)、車間(jian)換氣(qi)(qi)工(gong)(gong)程(cheng)(cheng)、工(gong)(gong)業(ye)(廠)排風(通(tong)(tong)風)凈化(hua)工(gong)(gong)程(cheng)(cheng)、水簾(lian)降溫(wen)工(gong)(gong)程(cheng)(cheng)。 (3)對外加工(gong)(gong)：剪板(ban)、折板(ban)、沖壓(ya)、液壓(ya)。 (4)來料加工(gong)(gong)或(huo)定(ding)做的(de)(de)生產銷售： 各(ge)種五金白(bai)(bai)(bai)鐵(tie)制品(pin)、鋁板(ban)、不(bu)銹(xiu)鋼及各(ge)種方圓(yuan)制品(pin)、水濂柜、不(bu)銹(xiu)鋼工(gong)(gong)作(zuo)(zuo)臺、貨架、水箱、吸塵桶。 我們在說說白(bai)(bai)(bai)鐵(tie)煙囪(cong)的(de)(de)加工(gong)(gong)流程(cheng)(cheng)：根據客(ke)(ke)戶的(de)(de)需(xu)(xu)求（圓(yuan)形(xing)還(huan)是方形(xing)），用(yong)(yong)專業(ye)的(de)(de)設備(bei)進(jin)行定(ding)型，然后壓(ya)邊，繼而對縫(feng)合處(chu)(chu)密(mi)封處(chu)(chu)理。說到(dao)這(zhe)里，有(you)些人(ren)就有(you)些不(bu)賴煩(fan)了(le)，我們主要(yao)是講白(bai)(bai)(bai)鐵(tie)的(de)(de)好(hao)處(chu)(chu)，怎么說到(dao)這(zhe)里了(le)呢，其實(shi)不(bu)然，我們在了(le)解它好(hao)處(chu)(chu)的(de)(de)同時，基礎是需(xu)(xu)要(yao)了(le)解的(de)(de)，因為(wei)那些好(hao)處(chu)(chu)都是從白(bai)(bai)(bai)鐵(tie)的(de)(de)材質而言(yan)的(de)(de)。 一、耐高(gao)溫(wen)：白(bai)(bai)(bai)鐵(tie)所承受的(de)(de)溫(wen)度是35℃-600℃，還(huan)可(ke)(ke)以根據客(ke)(ke)戶需(xu)(xu)求更高(gao)； 二、方、圓(yuan)隨(sui)用(yong)(yong)戶而定(ding)； 三、工(gong)(gong)作(zuo)(zuo)壓(ya)力強：一般在400mmWG，也可(ke)(ke)根據客(ke)(ke)戶需(xu)(xu)求更高(gao)； 四(si)、美觀、大方，可(ke)(ke)根據客(ke)(ke)戶的(de)(de)樣式制作(zuo)(zuo)（白(bai)(bai)(bai)鐵(tie)的(de)(de)可(ke)(ke)塑性更強）； 除(chu)以上(shang)之外還(huan)有(you)耐酸堿、阻燃、耐磨、耐拉等功能。有(you)良好(hao)的(de)(de)防(fang)火性能和良好(hao)的(de)(de)機械強度。 白(bai)(bai)(bai)鐵(tie)在很多(duo)地方都能用(yong)(yong)到(dao)，工(gong)(gong)廠廠房(fang)、電子設備(bei)、酒(jiu)店、冶金、制冷(leng)、高(gao)氣(qi)(qi)體、通(tong)(tong)風換氣(qi)(qi)、環保通(tong)(tong)風工(gong)(gong)程(cheng)(cheng)之抽(chou)放煙霧、濕氣(qi)(qi)、塵埃等，真可(ke)(ke)謂用(yong)(yong)途多(duo)多(duo)。

白鐵是好的消防排煙風管做風管加工、煙囪加工的好材料，那么在使用白鐵加工的時候需要涉及到哪些工具呢？ 專用的白鐵加工消防排煙風管剪(jian)(jian)刀、方錘(chui)、銼、鉗、鑷(nie)子、角(jiao)尺，鋼尺，白(bai)鐵(tie)剪(jian)(jian)、切管(guan)器，電動的(de)卷圓機(ji)、白(bai)鐵(tie)壓線機(ji)、白(bai)鐵(tie)打扣機(ji)，如要焊風管(guan)架子，還要用(yong)到(dao)電焊機(ji)，角(jiao)等。 白(bai)鐵(tie)加(jia)工(gong)的(de)工(gong)具是比較簡單(dan)的(de)，一般手工(gong)就能進行白(bai)鐵(tie)加(jia)工(gong)。

立管管卡安好的消防排煙風管裝時，應先把上面的一個管件固定好，再用線錘在中心處吊線，下面的管卡即可按線進行固定。風管消防排煙風管定制支(zhi)吊(diao)架間(jian)距如無設計要(yao)(yao)求時(shi)，對(dui)不(bu)保溫(wen)風(feng)管應符(fu)合下(xia)表的(de)要(yao)(yao)求。對(dui)于保溫(wen)風(feng)管的(de)支(zhi)、吊(diao)架間(jian)距無設計要(yao)(yao)求時(shi)，按(an)下(xia)表間(jian)距要(yao)(yao)求值乘(cheng)以0.85。重慶螺旋風(feng)管加工的(de)成品的(de)支(zhi)、吊(diao)架間(jian)距可以適(shi)當增(zeng)加。
