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)機(ji)(ji)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)(diao)一(yi)(yi)般指風(feng)(feng)管(guan)(guan)(guan)式(shi)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)(diao)機(ji)(ji)，俗(su)稱風(feng)(feng)管(guan)(guan)(guan)機(ji)(ji)，是空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)(diao)聯(lian)接風(feng)(feng)管(guan)(guan)(guan)向室內(nei)送風(feng)(feng)的(de)(de)(de)(de)(de)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)(diao)。它和中(zhong)(zhong)(zhong)央(yang)(yang)(yang)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)(diao)的(de)(de)(de)(de)(de)區別主要(yao)有：1、安裝成本(ben)不同(tong)：風(feng)(feng)管(guan)(guan)(guan)機(ji)(ji)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)(diao)和中(zhong)(zhong)(zhong)央(yang)(yang)(yang)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)(diao)達到的(de)(de)(de)(de)(de)制冷制熱效果都(dou)(dou)類似，然而風(feng)(feng)管(guan)(guan)(guan)機(ji)(ji)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)(diao)安裝成本(ben)相(xiang)(xiang)對(dui)(dui)(dui)來說更(geng)低，所以擁(yong)有更(geng)高的(de)(de)(de)(de)(de)性價(jia)比。很(hen)多公司家庭都(dou)(dou)會(hui)選擇風(feng)(feng)管(guan)(guan)(guan)機(ji)(ji)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)(diao)，其(qi)銷量也是非常不錯(cuo)。2、能(neng)(neng)耗(hao)不同(tong)：由(you)于(yu)中(zhong)(zhong)(zhong)央(yang)(yang)(yang)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)(diao)普(pu)遍采用變(bian)頻(pin)技(ji)術，風(feng)(feng)管(guan)(guan)(guan)機(ji)(ji)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)(diao)基(ji)本(ben)都(dou)(dou)是定(ding)頻(pin)技(ji)術，中(zhong)(zhong)(zhong)央(yang)(yang)(yang)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)(diao)的(de)(de)(de)(de)(de)能(neng)(neng)耗(hao)相(xiang)(xiang)對(dui)(dui)(dui)小(xiao)一(yi)(yi)些，節能(neng)(neng)能(neng)(neng)力更(geng)強。所以購買空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)(diao)時，除了要(yao)考(kao)(kao)慮(lv)購買價(jia)格外(wai)，能(neng)(neng)耗(hao)成本(ben)我(wo)們也是需要(yao)考(kao)(kao)慮(lv)的(de)(de)(de)(de)(de)。3、舒(shu)適(shi)度不同(tong)：安裝過風(feng)(feng)管(guan)(guan)(guan)機(ji)(ji)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)(diao)的(de)(de)(de)(de)(de)朋友(you)都(dou)(dou)知(zhi)道(dao)，風(feng)(feng)管(guan)(guan)(guan)機(ji)(ji)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)(diao)的(de)(de)(de)(de)(de)噪聲還(huan)是不小(xiao)的(de)(de)(de)(de)(de)。和中(zhong)(zhong)(zhong)央(yang)(yang)(yang)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)(diao)相(xiang)(xiang)比，風(feng)(feng)管(guan)(guan)(guan)機(ji)(ji)帶給人的(de)(de)(de)(de)(de)舒(shu)適(shi)度就更(geng)差(cha)些。4、工(gong)作原(yuan)理不同(tong)：風(feng)(feng)管(guan)(guan)(guan)機(ji)(ji)的(de)(de)(de)(de)(de)和普(pu)通的(de)(de)(de)(de)(de)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)(diao)一(yi)(yi)樣，一(yi)(yi)臺(tai)外(wai)機(ji)(ji)對(dui)(dui)(dui)應一(yi)(yi)臺(tai)室內(nei)機(ji)(ji)，屬(shu)(shu)于(yu)單聯(lian)機(ji)(ji)；中(zhong)(zhong)(zhong)央(yang)(yang)(yang)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)(diao)不一(yi)(yi)樣，一(yi)(yi)臺(tai)外(wai)機(ji)(ji)對(dui)(dui)(dui)應多臺(tai)室內(nei)機(ji)(ji)，屬(shu)(shu)于(yu)多聯(lian)機(ji)(ji)，且每個房間(jian)都(dou)(dou)能(neng)(neng)單獨控(kong)制。在工(gong)作原(yuan)理上，中(zhong)(zhong)(zhong)央(yang)(yang)(yang)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)(diao)的(de)(de)(de)(de)(de)是冷媒和空(kong)(kong)(kong)(kong)(kong)(kong)氣直接交換，制冷效果很(hen)快；風(feng)(feng)管(guan)(guan)(guan)機(ji)(ji)是以一(yi)(yi)種全(quan)空(kong)(kong)(kong)(kong)(kong)(kong)氣系統來工(gong)作，制冷速度相(xiang)(xiang)對(dui)(dui)(dui)慢些，還(huan)忽冷忽熱不夠穩定(ding)。5、適(shi)用范疇不同(tong)：風(feng)(feng)管(guan)(guan)(guan)機(ji)(ji)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)(diao)適(shi)用于(yu)相(xiang)(xiang)對(dui)(dui)(dui)較小(xiao)的(de)(de)(de)(de)(de)空(kong)(kong)(kong)(kong)(kong)(kong)間(jian)，中(zhong)(zhong)(zhong)央(yang)(yang)(yang)空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)(diao)適(shi)用于(yu)較大的(de)(de)(de)(de)(de)空(kong)(kong)(kong)(kong)(kong)(kong)間(jian)，空(kong)(kong)(kong)(kong)(kong)(kong)間(jian)的(de)(de)(de)(de)(de)大小(xiao)對(dui)(dui)(dui)于(yu)兩種空(kong)(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)(diao)(diao)的(de)(de)(de)(de)(de)選擇有一(yi)(yi)定(ding)的(de)(de)(de)(de)(de)影響。
三、風管安裝工藝流程
通風工程施(shi)工時，風管的(de)(de)安裝(zhuang)是一大重點，安裝(zhuang)風管要注意正(zheng)確(que)(que)(que)的(de)(de)安裝(zhuang)方法(fa)：1、 按照(zhao)設計圖紙找(zhao)出風管所處的(de)(de)位(wei)置及走向，參照(zhao)土建給出的(de)(de)基準線確(que)(que)(que)定(ding)(ding)風管底標高。2、 標高確(que)(que)(que)定(ding)(ding)后(hou)，按風管所在(zai)空(kong)間的(de)(de)位(wei)置及周(zhou)圍(wei)環境，確(que)(que)(que)定(ding)(ding)風管支(zhi)、吊(diao)、托架(jia)(jia)形式。3、設置吊(diao)點：根據吊(diao)架(jia)(jia)形式布置吊(diao)點，膨脹(zhang)螺栓(shuan)法(fa)安裝(zhuang)吊(diao)桿(gan)與橫檔托架(jia)(jia)。支(zhi)、吊(diao)架(jia)(jia)不(bu)(bu)得(de)安裝(zhuang)在(zai)風口、閥門、檢查孔等(deng)處，以(yi)免妨礙操(cao)作，吊(diao)架(jia)(jia)不(bu)(bu)得(de)直(zhi)接吊(diao)在(zai)法(fa)蘭上。4、需要安裝(zhuang)的(de)(de)風管在(zai)地面連成一定(ding)(ding)的(de)(de)長(chang)度，然后(hou)采用吊(diao)裝(zhuang)的(de)(de)方法(fa)就位(wei)；也可以(yi)把(ba)風管一節一節地放(fang)在(zai)支(zhi)架(jia)(jia)上逐節連接。一般安裝(zhuang)順序是先干管后(hou)支(zhi)管。5、就位(wei)在(zai)支(zhi)架(jia)(jia)上的(de)(de)風道，應撥正(zheng)位(wei)置，調整風道橫平豎直(zhi)，然后(hou)再按圖集要求固(gu)定(ding)(ding)即(ji)可。
