送(song)(song)(song)冷風，常見(jian)的(de)是空調(diao)的(de)管(guan)(guan)(guan)(guan)(guan)道，這種(zhong)管(guan)(guan)(guan)(guan)(guan)道需要加保溫材料(liao)，螺(luo)旋(xuan)風管(guan)(guan)(guan)(guan)(guan)可內貼保溫材料(liao)，外表看來美觀。螺(luo)旋(xuan)風管(guan)(guan)(guan)(guan)(guan)是用金屬帶料(liao)卷(juan)制成螺(luo)旋(xuan)形咬縫的(de)薄壁管(guan)(guan)(guan)(guan)(guan)，圓形，無焊接(jie)，螺(luo)旋(xuan)風管(guan)(guan)(guan)(guan)(guan)廠家(jia)，不漏氣(qi)，不漏水，多(duo)用于(yu)送(song)(song)(song)風和散裝(zhuang)物料(liao)輸(shu)送(song)(song)(song)，代替(ti)傳統的(de)白換管(guan)(guan)(guan)(guan)(guan)（即手工咬穎鐵管(guan)(guan)(guan)(guan)(guan)）。輸(shu)送(song)(song)(song)空氣(qi)溫度(du)高于(yu)80℃時，風管(guan)(guan)(guan)(guan)(guan)應(ying)(ying)按設計規定(ding)(ding)采(cai)取防護措施。風管(guan)(guan)(guan)(guan)(guan)測(ce)定(ding)(ding)孔應(ying)(ying)設置(zhi)在便于(yu)測(ce)量和觀察的(de)部位(wei);在吊頂內風管(guan)(guan)(guan)(guan)(guan)上的(de)測(ce)定(ding)(ding)孔，應(ying)(ying)在相應(ying)(ying)位(wei)置(zhi)留(liu)出活動吊頂板或檢(jian)查門(men)。

螺(luo)旋(xuan)(xuan)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)的(de)(de)(de)(de)優勢(shi)：標準化(hua)(hua)產品。螺(luo)旋(xuan)(xuan)圓(yuan)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)的(de)(de)(de)(de)配件(管(guan)(guan)(guan)(guan)件和接頭)的(de)(de)(de)(de)生產已(yi)高(gao)度自動化(hua)(hua)、系(xi)(xi)統(tong)化(hua)(hua)，并具有工(gong)(gong)業化(hua)(hua)的(de)(de)(de)(de)質量控制。安裝費用(yong)低(di)。圓(yuan)形風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)系(xi)(xi)統(tong)的(de)(de)(de)(de)安裝時(shi)間只有相類似的(de)(de)(de)(de)矩形管(guan)(guan)(guan)(guan)道的(de)(de)(de)(de)1/3。安裝螺(luo)旋(xuan)(xuan)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)的(de)(de)(de)(de)原則(ze)：觀察現場的(de)(de)(de)(de)施工(gong)(gong)情況(kuang)，因(yin)為現場施工(gong)(gong)情況(kuang)不一(yi)樣(yang)的(de)(de)(de)(de)話(hua)，連接的(de)(de)(de)(de)長度也是不一(yi)樣(yang)的(de)(de)(de)(de)，所(suo)以我們先(xian)要(yao)將螺(luo)旋(xuan)(xuan)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)一(yi)節一(yi)節的(de)(de)(de)(de)放(fang)在支(zhi)架上銜(xian)接起來，這是開(kai)始的(de)(de)(de)(de)步驟。螺(luo)旋(xuan)(xuan)風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)適用(yong)范(fan)圍(wei)非常廣(guang)泛。凈化(hua)(hua)系(xi)(xi)統(tong)送回風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)、中央空調通風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)、工(gong)(gong)業送排風(feng)(feng)(feng)通風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)、環保系(xi)(xi)統(tong)吸排風(feng)(feng)(feng)管(guan)(guan)(guan)(guan)、礦用(yong)涂膠(jiao)布(bu)風(feng)(feng)(feng)筒等。

風管(guan)(guan)出現噪(zao)聲(sheng)，引(yin)起這種現象的(de)原因可(ke)能是板材(cai)表面不(bu)(bu)平(ping)整(zheng)，厚度(du)不(bu)(bu)均(jun)勻(yun)，有明顯的(de)壓痕、裂紋、砂(sha)眼、結疤(ba)和(he)銹蝕等(deng)，或者(zhe)是風管(guan)(guan)平(ping)面下沉，側(ce)面向(xiang)外凸起，有明顯的(de)變形。螺(luo)旋(xuan)風管(guan)(guan)是用金屬(shu)帶料卷制成螺(luo)旋(xuan)形咬縫的(de)薄(bo)壁管(guan)(guan)，圓形，無焊接，不(bu)(bu)漏氣，不(bu)(bu)漏水，多用于送風和(he)散裝(zhuang)物料輸送，代替傳統的(de)白換管(guan)(guan)（即(ji)手工咬穎鐵管(guan)(guan)）。在風管(guan)(guan)安裝(zhuang)前(qian)一定要注(zhu)意先檢查材(cai)料出廠合(he)(he)格證書和(he)材(cai)料質量證明，然后檢查材(cai)料外觀;再測量鋼板厚度(du)。防(fang)止因材(cai)料不(bu)(bu)符合(he)(he)要求而返工。
