云南值得信賴的風管批發

1) 送風(feng)(feng)，包(bao)括通氣(qi)，如送鮮風(feng)(feng)和排(pai)氣(qi)，這個(ge)范圍很廣，如工(gong)廠車(che)間，生(sheng)產場地空氣(qi)，由于有(you)害氣(qi)體產生(sheng)需(xu)要(yao)排(pai)出(chu)室(shi)外(wai)，又需(xu)要(yao)把室(shi)外(wai)空氣(qi)輸(shu)送至室(shi)內。這時(shi)就(jiu)要(yao)使(shi)用流量大而(er)壓(ya)力小的(de)(de)空氣(qi)輸(shu)送管(guan)道(dao)，螺旋(xuan)風(feng)(feng)管(guan)就(jiu)適(shi)用，一(yi)般情況下使(shi)用鍍鋅鐵管(guan)，有(you)腐蝕性及特(te)別潮(chao)濕場所使(shi)用不銹鋼管(guan)。2) 送冷風(feng)(feng)。常見的(de)(de)是(shi)中央(yang)空調的(de)(de)管(guan)道(dao)，這種管(guan)道(dao)需(xu)要(yao)加(jia)保溫材料(liao)。螺旋(xuan)風(feng)(feng)管(guan)可內貼保溫材料(liao)，外(wai)表看來(lai)美觀。3) 排(pai)油煙。飯店、酒(jiu)樓(lou)、賓(bin)館的(de)(de)廚房均有(you)大量油煙產生(sheng)，需(xu)要(yao)排(pai)出(chu)，使(shi)用圓形(xing)的(de)(de)風(feng)(feng)管(guan)就(jiu)是(shi)油煙囪。在(zai)這里，螺旋(xuan)風(feng)(feng)管(guan)該叫做(zuo)油煙管(guan)。4) 除塵(chen)(chen)。有(you)些(xie)工(gong)廠生(sheng)產車(che)間很多塵(chen)(chen)埃，需(xu)要(yao)專門(men)的(de)(de)除塵(chen)(chen)裝置，其中量較大的(de)(de)管(guan)道(dao)，可使(shi)用螺旋(xuan)風(feng)(feng)管(guan)。5) 散(san)裝物(wu)料(liao)輸(shu)送。有(you)些(xie)工(gong)廠的(de)(de)生(sheng)產過程中，需(xu)要(yao)輸(shu)送松(song)散(san)的(de)(de)顆粒，特(te)別是(shi)比重不大的(de)(de)如發泡塑(su)料(liao)粒之類的(de)(de)使(shi)用螺旋(xuan)風(feng)(feng)管(guan)造價(jia)低、效(xiao)果好。

1、 薄鋼板矩形風管的剛度不夠,表現形式：風管的大邊上下有不同程度的下沉，兩側面小邊稍向外凸出，有明顯的變形。云南風管對產生的原因分析：① 制作風管的鋼板厚度不符合施工及驗收規范的要求；② 咬口的形式選擇不當；③ 沒有按照《施工及驗收規范》要求，對于邊長≥630 mm或保溫風管≥800 mm，其管長在1 200mm以上，均應采取加固措施。2 、薄鋼板矩形風管扭曲、翹角,表現形式：風管表面不平；對角線不相等；相鄰表面互不垂直；兩相對表面不平行及兩管端平面不平行等。風管產生的(de)(de)(de)原因分析：① 矩形板料(liao)(liao)下料(liao)(liao)后，未對四(si)(si)個(ge)(ge)角進行(xing)嚴格的(de)(de)(de)角方測量；② 風管(guan)的(de)(de)(de)大邊或小邊的(de)(de)(de)兩(liang)個(ge)(ge)相對面(mian)的(de)(de)(de)板料(liao)(liao)長度和寬(kuan)度不(bu)相等(deng)；③ 風管(guan)的(de)(de)(de)四(si)(si)個(ge)(ge)角處的(de)(de)(de)咬(yao)口寬(kuan)度不(bu)相等(deng)；④ 手工咬(yao)口合(he)縫受力不(bu)均。
