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)管(guan)(guan)(guan)(guan)(guan)機(ji)(ji)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)一般指(zhi)風(feng)管(guan)(guan)(guan)(guan)(guan)式空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)機(ji)(ji)，俗稱風(feng)管(guan)(guan)(guan)(guan)(guan)機(ji)(ji)，是(shi)(shi)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)聯(lian)接風(feng)管(guan)(guan)(guan)(guan)(guan)向室內(nei)送風(feng)的(de)(de)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)。它和中央(yang)(yang)(yang)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)的(de)(de)區別主要(yao)有：1、安裝成(cheng)本(ben)不(bu)(bu)(bu)同(tong)(tong)：風(feng)管(guan)(guan)(guan)(guan)(guan)機(ji)(ji)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)和中央(yang)(yang)(yang)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)達(da)到的(de)(de)制冷(leng)制熱效(xiao)果都(dou)類似，然而(er)風(feng)管(guan)(guan)(guan)(guan)(guan)機(ji)(ji)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)安裝成(cheng)本(ben)相對(dui)(dui)來說更(geng)低，所以擁有更(geng)高(gao)的(de)(de)性價比(bi)。很多(duo)公(gong)司家庭(ting)都(dou)會選擇(ze)(ze)風(feng)管(guan)(guan)(guan)(guan)(guan)機(ji)(ji)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)，其銷量(liang)也是(shi)(shi)非常不(bu)(bu)(bu)錯。2、能耗(hao)(hao)不(bu)(bu)(bu)同(tong)(tong)：由于(yu)中央(yang)(yang)(yang)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)普(pu)遍采用(yong)(yong)變頻技術(shu)，風(feng)管(guan)(guan)(guan)(guan)(guan)機(ji)(ji)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)基(ji)本(ben)都(dou)是(shi)(shi)定頻技術(shu)，中央(yang)(yang)(yang)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)的(de)(de)能耗(hao)(hao)相對(dui)(dui)小(xiao)(xiao)一些，節能能力更(geng)強(qiang)。所以購買空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)時，除了(le)要(yao)考慮購買價格外(wai)，能耗(hao)(hao)成(cheng)本(ben)我們也是(shi)(shi)需要(yao)考慮的(de)(de)。3、舒適度不(bu)(bu)(bu)同(tong)(tong)：安裝過風(feng)管(guan)(guan)(guan)(guan)(guan)機(ji)(ji)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)的(de)(de)朋友都(dou)知道，風(feng)管(guan)(guan)(guan)(guan)(guan)機(ji)(ji)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)的(de)(de)噪聲(sheng)還(huan)是(shi)(shi)不(bu)(bu)(bu)小(xiao)(xiao)的(de)(de)。和中央(yang)(yang)(yang)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)相比(bi)，風(feng)管(guan)(guan)(guan)(guan)(guan)機(ji)(ji)帶(dai)給人的(de)(de)舒適度就(jiu)更(geng)差些。4、工(gong)(gong)作(zuo)原(yuan)理不(bu)(bu)(bu)同(tong)(tong)：風(feng)管(guan)(guan)(guan)(guan)(guan)機(ji)(ji)的(de)(de)和普(pu)通的(de)(de)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)一樣，一臺外(wai)機(ji)(ji)對(dui)(dui)應一臺室內(nei)機(ji)(ji)，屬于(yu)單(dan)聯(lian)機(ji)(ji)；中央(yang)(yang)(yang)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)不(bu)(bu)(bu)一樣，一臺外(wai)機(ji)(ji)對(dui)(dui)應多(duo)臺室內(nei)機(ji)(ji)，屬于(yu)多(duo)聯(lian)機(ji)(ji)，且每個房間都(dou)能單(dan)獨控(kong)制。在工(gong)(gong)作(zuo)原(yuan)理上，中央(yang)(yang)(yang)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)的(de)(de)是(shi)(shi)冷(leng)媒和空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)氣直接交換，制冷(leng)效(xiao)果很快；風(feng)管(guan)(guan)(guan)(guan)(guan)機(ji)(ji)是(shi)(shi)以一種全空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)氣系統來工(gong)(gong)作(zuo)，制冷(leng)速度相對(dui)(dui)慢些，還(huan)忽冷(leng)忽熱不(bu)(bu)(bu)夠穩定。5、適用(yong)(yong)范(fan)疇不(bu)(bu)(bu)同(tong)(tong)：風(feng)管(guan)(guan)(guan)(guan)(guan)機(ji)(ji)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)適用(yong)(yong)于(yu)相對(dui)(dui)較小(xiao)(xiao)的(de)(de)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)間，中央(yang)(yang)(yang)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)適用(yong)(yong)于(yu)較大的(de)(de)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)間，空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)間的(de)(de)大小(xiao)(xiao)對(dui)(dui)于(yu)兩種空(kong)(kong)(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)的(de)(de)選擇(ze)(ze)有一定的(de)(de)影(ying)響。
三、風管安裝工藝流程
通風(feng)(feng)工程施(shi)工時，風(feng)(feng)管(guan)(guan)(guan)的安裝(zhuang)(zhuang)是一(yi)大重點，安裝(zhuang)(zhuang)風(feng)(feng)管(guan)(guan)(guan)要(yao)注意正(zheng)確(que)的安裝(zhuang)(zhuang)方(fang)法：1、 按照(zhao)設計圖(tu)紙找(zhao)出風(feng)(feng)管(guan)(guan)(guan)所處(chu)(chu)的位置(zhi)及(ji)走(zou)向(xiang)，參照(zhao)土建給出的基(ji)準線(xian)確(que)定風(feng)(feng)管(guan)(guan)(guan)底(di)標高。2、 標高確(que)定后，按風(feng)(feng)管(guan)(guan)(guan)所在(zai)(zai)空間的位置(zhi)及(ji)周圍環境，確(que)定風(feng)(feng)管(guan)(guan)(guan)支、吊(diao)、托(tuo)架(jia)形式。3、設置(zhi)吊(diao)點：根據吊(diao)架(jia)形式布(bu)置(zhi)吊(diao)點，膨脹螺栓法安裝(zhuang)(zhuang)吊(diao)桿(gan)與橫檔(dang)托(tuo)架(jia)。支、吊(diao)架(jia)不得安裝(zhuang)(zhuang)在(zai)(zai)風(feng)(feng)口(kou)、閥門、檢查孔等處(chu)(chu)，以(yi)免妨礙操(cao)作，吊(diao)架(jia)不得直(zhi)接(jie)吊(diao)在(zai)(zai)法蘭上。4、需要(yao)安裝(zhuang)(zhuang)的風(feng)(feng)管(guan)(guan)(guan)在(zai)(zai)地(di)面連成一(yi)定的長度，然后采用吊(diao)裝(zhuang)(zhuang)的方(fang)法就位；也可以(yi)把風(feng)(feng)管(guan)(guan)(guan)一(yi)節一(yi)節地(di)放在(zai)(zai)支架(jia)上逐節連接(jie)。一(yi)般(ban)安裝(zhuang)(zhuang)順序是先干管(guan)(guan)(guan)后支管(guan)(guan)(guan)。5、就位在(zai)(zai)支架(jia)上的風(feng)(feng)道(dao)，應撥(bo)正(zheng)位置(zhi)，調整風(feng)(feng)道(dao)橫平豎直(zhi)，然后再按圖(tu)集(ji)要(yao)求固(gu)定即可。
