一、風管加工制作流程
風管是用于空氣輸送和分布的管道系統，它的種類眾多，不同風管的制作工藝流程有所不同，以常用的金屬風管為例，其加工制作工藝流程如下：1、風管尺寸的核定。根據設計要求、圖紙會審紀要，結合現場實測數據繪制風管加工草圖，并標明系統風量、風壓測定孔的位置。2、風管展開。依照風管施工圖（或放樣圖）把風管的表面形狀按實際的大小鋪在板料上；展開方法有三種即平行線展開法、放射線展開法和三角線展開法。3、板材剪切前必須進行下料復核，復核無誤后按劃線形狀進行剪切。4、板材下料后在壓口之前，必須用倒角機或剪刀進行倒角。5、板材的拼接。和圓形風管的閉合咬口可采用單咬口；矩形風管或配件的四角組合可采用轉角咬口、聯合角咬口、按扣式咬角；圓形彎管的組合可采用立咬口。6、畫好折方線，在折方機上折方。制作圓風管時，將咬口兩端拍成圓弧狀放在卷圓機上圈圓。7、折方或卷圓后的鋼板用合縫機或手工進行合縫。操作時，用力均勻，不宜過重。咬口縫結合應緊密，不得有脹裂和半咬口現象。8、風管的加固：風管一般可采用楞筋、立筋、角鋼、扁鋼、加固筋和管內支撐等形式加固。如果您有購買風管的需要，可以先來了解一下風管十大品牌。
二、風管機和中央空調的區別
風(feng)(feng)管(guan)(guan)(guan)(guan)機(ji)(ji)(ji)(ji)(ji)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)一(yi)(yi)般指風(feng)(feng)管(guan)(guan)(guan)(guan)式(shi)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)機(ji)(ji)(ji)(ji)(ji)，俗(su)稱風(feng)(feng)管(guan)(guan)(guan)(guan)機(ji)(ji)(ji)(ji)(ji)，是(shi)(shi)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)聯(lian)接風(feng)(feng)管(guan)(guan)(guan)(guan)向室內送(song)風(feng)(feng)的(de)(de)(de)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)。它和(he)中央(yang)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)的(de)(de)(de)區別主要(yao)有(you)：1、安裝成(cheng)(cheng)本不(bu)(bu)同(tong)：風(feng)(feng)管(guan)(guan)(guan)(guan)機(ji)(ji)(ji)(ji)(ji)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)和(he)中央(yang)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)達到的(de)(de)(de)制冷制熱效(xiao)果都(dou)類似(si)，然而風(feng)(feng)管(guan)(guan)(guan)(guan)機(ji)(ji)(ji)(ji)(ji)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)安裝成(cheng)(cheng)本相對(dui)來說更低，所以(yi)擁有(you)更高的(de)(de)(de)性價(jia)比。很多(duo)公(gong)司家庭都(dou)會選(xuan)擇(ze)風(feng)(feng)管(guan)(guan)(guan)(guan)機(ji)(ji)(ji)(ji)(ji)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)，其銷量也是(shi)(shi)非常(chang)不(bu)(bu)錯。2、能耗(hao)不(bu)(bu)同(tong)：由于(yu)(yu)(yu)中央(yang)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)普遍采用變(bian)頻技術，風(feng)(feng)管(guan)(guan)(guan)(guan)機(ji)(ji)(ji)(ji)(ji)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)基本都(dou)是(shi)(shi)定(ding)頻技術，中央(yang)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)的(de)(de)(de)能耗(hao)相對(dui)小(xiao)一(yi)(yi)些，節能能力更強。所以(yi)購買(mai)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)時，除了要(yao)考(kao)慮購買(mai)價(jia)格外(wai)，能耗(hao)成(cheng)(cheng)本我們也是(shi)(shi)需要(yao)考(kao)慮的(de)(de)(de)。3、舒適度(du)不(bu)(bu)同(tong)：安裝過風(feng)(feng)管(guan)(guan)(guan)(guan)機(ji)(ji)(ji)(ji)(ji)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)的(de)(de)(de)朋(peng)友都(dou)知(zhi)道，風(feng)(feng)管(guan)(guan)(guan)(guan)機(ji)(ji)(ji)(ji)(ji)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)的(de)(de)(de)噪(zao)聲還是(shi)(shi)不(bu)(bu)小(xiao)的(de)(de)(de)。和(he)中央(yang)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)相比，風(feng)(feng)管(guan)(guan)(guan)(guan)機(ji)(ji)(ji)(ji)(ji)帶給(gei)人的(de)(de)(de)舒適度(du)就更差些。4、工作原理不(bu)(bu)同(tong)：風(feng)(feng)管(guan)(guan)(guan)(guan)機(ji)(ji)(ji)(ji)(ji)的(de)(de)(de)和(he)普通的(de)(de)(de)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)一(yi)(yi)樣，一(yi)(yi)臺外(wai)機(ji)(ji)(ji)(ji)(ji)對(dui)應一(yi)(yi)臺室內機(ji)(ji)(ji)(ji)(ji)，屬于(yu)(yu)(yu)單聯(lian)機(ji)(ji)(ji)(ji)(ji)；中央(yang)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)不(bu)(bu)一(yi)(yi)樣，一(yi)(yi)臺外(wai)機(ji)(ji)(ji)(ji)(ji)對(dui)應多(duo)臺室內機(ji)(ji)(ji)(ji)(ji)，屬于(yu)(yu)(yu)多(duo)聯(lian)機(ji)(ji)(ji)(ji)(ji)，且每(mei)個(ge)房間(jian)(jian)都(dou)能單獨控(kong)制。在工作原理上(shang)，中央(yang)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)的(de)(de)(de)是(shi)(shi)冷媒和(he)空(kong)(kong)(kong)(kong)(kong)(kong)氣直接交換，制冷效(xiao)果很快；風(feng)(feng)管(guan)(guan)(guan)(guan)機(ji)(ji)(ji)(ji)(ji)是(shi)(shi)以(yi)一(yi)(yi)種全(quan)空(kong)(kong)(kong)(kong)(kong)(kong)氣系(xi)統來工作，制冷速度(du)相對(dui)慢些，還忽冷忽熱不(bu)(bu)夠穩定(ding)。5、適用范疇不(bu)(bu)同(tong)：風(feng)(feng)管(guan)(guan)(guan)(guan)機(ji)(ji)(ji)(ji)(ji)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)適用于(yu)(yu)(yu)相對(dui)較小(xiao)的(de)(de)(de)空(kong)(kong)(kong)(kong)(kong)(kong)間(jian)(jian)，中央(yang)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)適用于(yu)(yu)(yu)較大(da)的(de)(de)(de)空(kong)(kong)(kong)(kong)(kong)(kong)間(jian)(jian)，空(kong)(kong)(kong)(kong)(kong)(kong)間(jian)(jian)的(de)(de)(de)大(da)小(xiao)對(dui)于(yu)(yu)(yu)兩種空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)的(de)(de)(de)選(xuan)擇(ze)有(you)一(yi)(yi)定(ding)的(de)(de)(de)影(ying)響。
三、風管安裝工藝流程
通風(feng)工程施工時(shi)，風(feng)管的安(an)(an)裝(zhuang)是一(yi)(yi)大重點(dian)，安(an)(an)裝(zhuang)風(feng)管要(yao)注意(yi)正確(que)(que)的安(an)(an)裝(zhuang)方法(fa)：1、 按照設計圖(tu)紙找出風(feng)管所處的位置(zhi)(zhi)及走向，參照土(tu)建給出的基準線確(que)(que)定(ding)(ding)風(feng)管底(di)標高(gao)。2、 標高(gao)確(que)(que)定(ding)(ding)后(hou)，按風(feng)管所在(zai)空間的位置(zhi)(zhi)及周圍環境，確(que)(que)定(ding)(ding)風(feng)管支(zhi)、吊(diao)(diao)、托(tuo)(tuo)架形式。3、設置(zhi)(zhi)吊(diao)(diao)點(dian)：根據吊(diao)(diao)架形式布置(zhi)(zhi)吊(diao)(diao)點(dian)，膨(peng)脹螺(luo)栓法(fa)安(an)(an)裝(zhuang)吊(diao)(diao)桿與橫檔托(tuo)(tuo)架。支(zhi)、吊(diao)(diao)架不得安(an)(an)裝(zhuang)在(zai)風(feng)口、閥門、檢查孔等處，以免妨(fang)礙操(cao)作，吊(diao)(diao)架不得直接(jie)(jie)吊(diao)(diao)在(zai)法(fa)蘭上(shang)。4、需(xu)要(yao)安(an)(an)裝(zhuang)的風(feng)管在(zai)地面連成一(yi)(yi)定(ding)(ding)的長度，然(ran)(ran)后(hou)采(cai)用吊(diao)(diao)裝(zhuang)的方法(fa)就位；也(ye)可(ke)以把風(feng)管一(yi)(yi)節一(yi)(yi)節地放(fang)在(zai)支(zhi)架上(shang)逐節連接(jie)(jie)。一(yi)(yi)般(ban)安(an)(an)裝(zhuang)順序是先干管后(hou)支(zhi)管。5、就位在(zai)支(zhi)架上(shang)的風(feng)道(dao)，應撥正位置(zhi)(zhi)，調整(zheng)風(feng)道(dao)橫平豎直，然(ran)(ran)后(hou)再按圖(tu)集要(yao)求固定(ding)(ding)即可(ke)。
