通風(feng)風(feng)管(guan)(guan)(guan)加工時的(de)(de)(de)風(feng)量(liang)(liang)和速(su)度(du)公式計算風(feng)量(liang)(liang)=通風(feng)端子的(de)(de)(de)總和風(feng)速(su)=管(guan)(guan)(guan)道(dao)中的(de)(de)(de)流(liu)速(su)風(feng)壓(ya)(ya)=排氣(qi)(qi)時管(guan)(guan)(guan)道(dao)中的(de)(de)(de)壓(ya)(ya)力(li) ?空氣(qi)(qi)供(gong)應管(guan)(guan)(guan)需(xu)要從(cong)空氣(qi)(qi)管(guan)(guan)(guan)側壁上(shang)的(de)(de)(de)多個空氣(qi)(qi)開口(kou)(kou)（或短(duan)管(guan)(guan)(guan)）以相(xiang)(xiang)同的(de)(de)(de)出(chu)口(kou)(kou)速(su)度(du)以相(xiang)(xiang)同的(de)(de)(de)出(chu)口(kou)(kou)速(su)度(du)均(jun)勻地向室內發(fa)送(song)相(xiang)(xiang)同數(shu)量(liang)(liang)的(de)(de)(de)空氣(qi)(qi)。 這種供(gong)氣(qi)(qi)管(guan)(guan)(guan)稱為統(tong)一供(gong)氣(qi)(qi)管(guan)(guan)(guan)。均(jun)勻送(song)風(feng)管(guan)(guan)(guan)道(dao)結構有(you)兩種形式，一種是均(jun)勻送(song)風(feng)管(guan)(guan)(guan)道(dao)的(de)(de)(de)橫截(jie)(jie)面(mian)(mian)發(fa)生變(bian)化（即(ji)橫截(jie)(jie)面(mian)(mian)逐漸減小）和側面(mian)(mian)出(chu)風(feng)口(kou)(kou)（或短(duan)管(guan)(guan)(guan)）的(de)(de)(de)面(mian)(mian)積 是平等的(de)(de)(de); 另一個是供(gong)氣(qi)(qi)管(guan)(guan)(guan)道(dao)的(de)(de)(de)橫截(jie)(jie)面(mian)(mian)沒有(you)變(bian)化。側面(mian)(mian)出(chu)氣(qi)(qi)孔（或短(duan)管(guan)(guan)(guan)）的(de)(de)(de)面(mian)(mian)積不相(xiang)(xiang)等。

計(ji)算(suan)的(de)(de)(de)(de)基本原理是保持(chi)每(mei)個(ge)(ge)側(ce)孔的(de)(de)(de)(de)靜(jing)壓力(li)相等。 根據管道(dao)阻力(li)的(de)(de)(de)(de)計(ji)算(suan)和能量(liang)方(fang)程，可以(yi)得到(dao)每(mei)個(ge)(ge)側(ce)孔的(de)(de)(de)(de)靜(jing)壓力(li)相等的(de)(de)(de)(de)方(fang)程。 計(ji)算(suan)均勻(yun)供氣(qi)(qi)管的(de)(de)(de)(de)目的(de)(de)(de)(de)是確定側(ce)孔的(de)(de)(de)(de)面積，空氣(qi)(qi)管道(dao)的(de)(de)(de)(de)阻力(li)和均勻(yun)供氣(qi)(qi)管的(de)(de)(de)(de)截面。 當確定法蘭風管定制(zhi)側(ce)孔的(de)(de)(de)(de)數(shu)量(liang)，側(ce)孔的(de)(de)(de)(de)間距以(yi)及(ji)每(mei)個(ge)(ge)側(ce)孔的(de)(de)(de)(de)空氣(qi)(qi)供應量(liang)時，可以(yi)根據上述原理來計(ji)算(suan)均勻(yun)的(de)(de)(de)(de)空氣(qi)(qi)供應管道(dao)的(de)(de)(de)(de)尺(chi)寸(cun)。

風(feng)管(guan)(guan)廠(chang)家均(jun)勻送風(feng)管(guan)(guan)道的計(ji)算方(fang)法是：（1）確定側(ce)孔(kong)(kong)(kong)的數量(liang)(liang)，側(ce)孔(kong)(kong)(kong)之間的距離以及每(mei)個側(ce)孔(kong)(kong)(kong)的送風(feng)量(liang)(liang)。（2）計(ji)算出(chu)側(ce)孔(kong)(kong)(kong)面(mian)積f0 m2，其(qi)中(zhong)L0——均(jun)勻供(gong)氣(qi)管(guan)(guan)的總風(feng)量(liang)(liang)，m3/ h；-側(ce)孔(kong)(kong)(kong)的平均(jun)流出(chu)速(su)度(du)，m / s； ?f0——側(ce)孔(kong)(kong)(kong)面(mian)積，m2。 在側(ce)孔(kong)(kong)(kong)靜(jing)壓(ya)流量(liang)(liang)方(fang)程中(zhong)，μ——節流孔(kong)(kong)(kong)的流量(liang)(liang)系(xi)數。（3）計(ji)算供(gong)氣(qi)管(guan)(guan)的直徑（或(huo)截面(mian)尺(chi)寸）。 首(shou)先根據vj /vd≥1.73的原理設置vd（管(guan)(guan)道中(zhong)的速(su)度(du)），太原通風(feng)管(guan)(guan)道加工，然(ran)后(hou)計(ji)算相應截面(mian)的管(guan)(guan)道直徑D。（4）計(ji)算管(guan)(guan)道的阻力側(ce)孔(kong)(kong)(kong)應有靜(jing)壓(ya)。

我們將為(wei)你提供詳細(xi)的流(liu)行資訊，精彩的新聞知識，讓(rang)您對產品有更深的了解

螺(luo)(luo)旋(xuan)風(feng)(feng)管(guan)市場上按材質一般(ban)分為三類：鍍鋅(xin)螺(luo)(luo)旋(xuan)風(feng)(feng)管(guan)、不銹鋼(gang)螺(luo)(luo)旋(xuan)風(feng)(feng)管(guan)以及(ji)復合螺(luo)(luo)旋(xuan)風(feng)(feng)管(guan)。其中，不銹鋼(gang)風(feng)(feng)管(guan)質量好，適用性強，但價格(ge)高(gao)。

市場通廣的(de)螺旋(xuan)風(feng)(feng)(feng)管(guan)(guan)是鍍(du)鋅板的(de)。鍍(du)鋅板螺旋(xuan)風(feng)(feng)(feng)管(guan)(guan)，基本是不銹鋼螺旋(xuan)風(feng)(feng)(feng)管(guan)(guan)的(de)特性，但是價格相(xiang)對只有不銹鋼風(feng)(feng)(feng)管(guan)(guan)的(de)三分之二甚(shen)至更低。復合螺旋(xuan)風(feng)(feng)(feng)管(guan)(guan)一般應用在外界(jie)環境較為普通，對風(feng)(feng)(feng)管(guan)(guan)要(yao)求(qiu)不太高的(de)場所。

螺旋風(feng)管具(ju)有以下(xia)特(te)點：

1、外觀光滑，無鋅瘤、毛刺，呈銀白色。

2、安裝(zhuang)方便，連接點少。

3、通(tong)風阻力(li)小，通(tong)風噪聲小。

4、強度(du)與剛性(xing)均(jun)好。

5、厚度均(jun)為(wei)可(ke)控(kong)，在5-107μm之內(nei)任意選擇。

6、無(wu)(wu)氫(qing)脆、無(wu)(wu)溫度危害(hai)，可(ke)保證(zheng)材料力(li)學(xue)性能(neng)不變。

7、可代替(ti)部分需熱(re)鍍鋅的工藝。

8、耐腐(fu)蝕性好，中(zhong)性鹽霧(wu)試驗達240小時。

9、采用(yong)熱鍍(du)鋅方法完(wan)成，適用(yong)于各種強酸、堿(jian)霧氣等強腐蝕環(huan)境中。

10、可(ke)根據客(ke)戶要求，專(zhuan)門設(she)計、定做各(ge)種規格風管。
