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)(feng)(feng)管(guan)(guan)機(ji)(ji)(ji)(ji)空(kong)(kong)(kong)調(diao)(diao)一(yi)般指(zhi)風(feng)(feng)(feng)(feng)管(guan)(guan)式空(kong)(kong)(kong)調(diao)(diao)機(ji)(ji)(ji)(ji)，俗稱(cheng)風(feng)(feng)(feng)(feng)管(guan)(guan)機(ji)(ji)(ji)(ji)，是空(kong)(kong)(kong)調(diao)(diao)聯(lian)接風(feng)(feng)(feng)(feng)管(guan)(guan)向室(shi)內(nei)送(song)風(feng)(feng)(feng)(feng)的(de)(de)空(kong)(kong)(kong)調(diao)(diao)。它和(he)中(zhong)(zhong)(zhong)央(yang)空(kong)(kong)(kong)調(diao)(diao)的(de)(de)區別(bie)主(zhu)要(yao)有：1、安裝(zhuang)成本(ben)不(bu)同(tong)：風(feng)(feng)(feng)(feng)管(guan)(guan)機(ji)(ji)(ji)(ji)空(kong)(kong)(kong)調(diao)(diao)和(he)中(zhong)(zhong)(zhong)央(yang)空(kong)(kong)(kong)調(diao)(diao)達到(dao)的(de)(de)制冷(leng)制熱(re)效果(guo)(guo)都類似(si)，然(ran)而(er)風(feng)(feng)(feng)(feng)管(guan)(guan)機(ji)(ji)(ji)(ji)空(kong)(kong)(kong)調(diao)(diao)安裝(zhuang)成本(ben)相(xiang)(xiang)(xiang)對(dui)來(lai)說更(geng)(geng)低，所以(yi)擁有更(geng)(geng)高的(de)(de)性價(jia)比。很(hen)多公司家庭都會選擇風(feng)(feng)(feng)(feng)管(guan)(guan)機(ji)(ji)(ji)(ji)空(kong)(kong)(kong)調(diao)(diao)，其(qi)銷量也是非常不(bu)錯。2、能(neng)耗(hao)不(bu)同(tong)：由于(yu)(yu)(yu)中(zhong)(zhong)(zhong)央(yang)空(kong)(kong)(kong)調(diao)(diao)普遍采(cai)用變(bian)頻(pin)(pin)技術，風(feng)(feng)(feng)(feng)管(guan)(guan)機(ji)(ji)(ji)(ji)空(kong)(kong)(kong)調(diao)(diao)基本(ben)都是定頻(pin)(pin)技術，中(zhong)(zhong)(zhong)央(yang)空(kong)(kong)(kong)調(diao)(diao)的(de)(de)能(neng)耗(hao)相(xiang)(xiang)(xiang)對(dui)小一(yi)些，節(jie)能(neng)能(neng)力(li)更(geng)(geng)強。所以(yi)購買(mai)空(kong)(kong)(kong)調(diao)(diao)時，除(chu)了(le)要(yao)考(kao)慮購買(mai)價(jia)格外，能(neng)耗(hao)成本(ben)我們也是需要(yao)考(kao)慮的(de)(de)。3、舒適度(du)不(bu)同(tong)：安裝(zhuang)過風(feng)(feng)(feng)(feng)管(guan)(guan)機(ji)(ji)(ji)(ji)空(kong)(kong)(kong)調(diao)(diao)的(de)(de)朋友都知(zhi)道，風(feng)(feng)(feng)(feng)管(guan)(guan)機(ji)(ji)(ji)(ji)空(kong)(kong)(kong)調(diao)(diao)的(de)(de)噪聲(sheng)還(huan)是不(bu)小的(de)(de)。和(he)中(zhong)(zhong)(zhong)央(yang)空(kong)(kong)(kong)調(diao)(diao)相(xiang)(xiang)(xiang)比，風(feng)(feng)(feng)(feng)管(guan)(guan)機(ji)(ji)(ji)(ji)帶給人的(de)(de)舒適度(du)就更(geng)(geng)差些。4、工(gong)作(zuo)(zuo)原理(li)不(bu)同(tong)：風(feng)(feng)(feng)(feng)管(guan)(guan)機(ji)(ji)(ji)(ji)的(de)(de)和(he)普通的(de)(de)空(kong)(kong)(kong)調(diao)(diao)一(yi)樣(yang)，一(yi)臺外機(ji)(ji)(ji)(ji)對(dui)應(ying)一(yi)臺室(shi)內(nei)機(ji)(ji)(ji)(ji)，屬于(yu)(yu)(yu)單(dan)聯(lian)機(ji)(ji)(ji)(ji)；中(zhong)(zhong)(zhong)央(yang)空(kong)(kong)(kong)調(diao)(diao)不(bu)一(yi)樣(yang)，一(yi)臺外機(ji)(ji)(ji)(ji)對(dui)應(ying)多臺室(shi)內(nei)機(ji)(ji)(ji)(ji)，屬于(yu)(yu)(yu)多聯(lian)機(ji)(ji)(ji)(ji)，且每個房(fang)間(jian)都能(neng)單(dan)獨控制。在工(gong)作(zuo)(zuo)原理(li)上，中(zhong)(zhong)(zhong)央(yang)空(kong)(kong)(kong)調(diao)(diao)的(de)(de)是冷(leng)媒和(he)空(kong)(kong)(kong)氣(qi)直接交(jiao)換，制冷(leng)效果(guo)(guo)很(hen)快(kuai)；風(feng)(feng)(feng)(feng)管(guan)(guan)機(ji)(ji)(ji)(ji)是以(yi)一(yi)種(zhong)全空(kong)(kong)(kong)氣(qi)系統來(lai)工(gong)作(zuo)(zuo)，制冷(leng)速度(du)相(xiang)(xiang)(xiang)對(dui)慢(man)些，還(huan)忽冷(leng)忽熱(re)不(bu)夠(gou)穩定。5、適用范疇不(bu)同(tong)：風(feng)(feng)(feng)(feng)管(guan)(guan)機(ji)(ji)(ji)(ji)空(kong)(kong)(kong)調(diao)(diao)適用于(yu)(yu)(yu)相(xiang)(xiang)(xiang)對(dui)較小的(de)(de)空(kong)(kong)(kong)間(jian)，中(zhong)(zhong)(zhong)央(yang)空(kong)(kong)(kong)調(diao)(diao)適用于(yu)(yu)(yu)較大的(de)(de)空(kong)(kong)(kong)間(jian)，空(kong)(kong)(kong)間(jian)的(de)(de)大小對(dui)于(yu)(yu)(yu)兩(liang)種(zhong)空(kong)(kong)(kong)調(diao)(diao)的(de)(de)選擇有一(yi)定的(de)(de)影響。
三、風管安裝工藝流程
通風(feng)(feng)(feng)工程施工時(shi)，風(feng)(feng)(feng)管(guan)(guan)的(de)(de)(de)安(an)裝(zhuang)(zhuang)是一大(da)重點，安(an)裝(zhuang)(zhuang)風(feng)(feng)(feng)管(guan)(guan)要注(zhu)意(yi)正確的(de)(de)(de)安(an)裝(zhuang)(zhuang)方(fang)法：1、 按(an)(an)照設計圖紙找出(chu)風(feng)(feng)(feng)管(guan)(guan)所處(chu)的(de)(de)(de)位置及走向，參照土建(jian)給出(chu)的(de)(de)(de)基準線確定風(feng)(feng)(feng)管(guan)(guan)底標高。2、 標高確定后(hou)(hou)，按(an)(an)風(feng)(feng)(feng)管(guan)(guan)所在(zai)(zai)(zai)空間(jian)的(de)(de)(de)位置及周圍環境，確定風(feng)(feng)(feng)管(guan)(guan)支(zhi)(zhi)、吊(diao)(diao)(diao)、托架形式(shi)。3、設置吊(diao)(diao)(diao)點：根據吊(diao)(diao)(diao)架形式(shi)布置吊(diao)(diao)(diao)點，膨脹螺栓(shuan)法安(an)裝(zhuang)(zhuang)吊(diao)(diao)(diao)桿與橫檔托架。支(zhi)(zhi)、吊(diao)(diao)(diao)架不(bu)得安(an)裝(zhuang)(zhuang)在(zai)(zai)(zai)風(feng)(feng)(feng)口、閥門、檢查(cha)孔等處(chu)，以免妨礙(ai)操作，吊(diao)(diao)(diao)架不(bu)得直接(jie)吊(diao)(diao)(diao)在(zai)(zai)(zai)法蘭上。4、需(xu)要安(an)裝(zhuang)(zhuang)的(de)(de)(de)風(feng)(feng)(feng)管(guan)(guan)在(zai)(zai)(zai)地面連(lian)成一定的(de)(de)(de)長度，然后(hou)(hou)采用(yong)吊(diao)(diao)(diao)裝(zhuang)(zhuang)的(de)(de)(de)方(fang)法就(jiu)位；也可以把風(feng)(feng)(feng)管(guan)(guan)一節一節地放在(zai)(zai)(zai)支(zhi)(zhi)架上逐節連(lian)接(jie)。一般安(an)裝(zhuang)(zhuang)順序(xu)是先干管(guan)(guan)后(hou)(hou)支(zhi)(zhi)管(guan)(guan)。5、就(jiu)位在(zai)(zai)(zai)支(zhi)(zhi)架上的(de)(de)(de)風(feng)(feng)(feng)道，應撥(bo)正位置，調(diao)整風(feng)(feng)(feng)道橫平(ping)豎直，然后(hou)(hou)再按(an)(an)圖集要求(qiu)固(gu)定即可。
