通風(fēng)是一種換氣設(shè)備，它是用機(jī)械或自然的方法向室內(nèi)空間送入足夠的新鮮空氣，同時(shí)把室內(nèi)不符合衛(wèi)生要求的污濁空氣排出，使室內(nèi)空氣滿足衛(wèi)生要求和生產(chǎn)過(guò)程需要，通風(fēng)管道設(shè)備有著十分寬泛的使用范圍。下面小編就來(lái)為大家介紹一下通風(fēng)管道設(shè)備安裝的規(guī)范細(xì)則以及常見(jiàn)問(wèn)題。 </p> <p> 當(dāng)今，建筑中完成通風(fēng)工作的各項(xiàng)設(shè)施，統(tǒng)稱通風(fēng)管道設(shè)備。通風(fēng)管道設(shè)備分排風(fēng)扇，換氣扇，風(fēng)機(jī)等，又分工業(yè)用及家用二種。而風(fēng)機(jī)又分高、中、低、負(fù)壓等。 </p> <p> 通風(fēng)管道設(shè)備安裝的規(guī)范細(xì)則 </p> <p> 1、通風(fēng)機(jī)安裝應(yīng)符合下列規(guī)定 </p> <p> <br /> </p><p> 消聲器安裝應(yīng)符合下列規(guī)定 </p> <p> （1）消聲器框架必須牢固，共振腔的隔板尺寸貼緊，正確，隔板與壁板結(jié)合處外殼嚴(yán)密不漏。 </p> <p>

通風(fēng)管道選用什么材質(zhì)？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="婺城區(qū)口碑好通風(fēng)管道,通風(fēng)管道" src="https://tyunfile.71360.com/UploadFile/15958815551/637255771744033203/4702436.png"></div><p> (二)測(cè)試孔和測(cè)定點(diǎn) </p> <p> 由于速度分布的不均勻性，壓力分布也是不均勻的。因此，必須在同一斷面上多點(diǎn)測(cè)量，然后求出該斷面的平均值。 </p> <p> 1圓形風(fēng)道 </p> <p> 在同一斷面設(shè)置兩個(gè)彼此垂直的測(cè)孔，并將管道斷面分成一定數(shù)量的等面積同心環(huán)，對(duì)于圓形風(fēng)道，測(cè)點(diǎn)越多，測(cè)量精度越高。 </p> <p> 2矩形風(fēng)道 </p> <p> 可將風(fēng)道斷面劃分為若干等面積的小矩形，測(cè)點(diǎn)布置在每個(gè)小矩形的中心，小矩形每邊的長(zhǎng)度為200mm左右，圓風(fēng)管測(cè)點(diǎn)與管壁距離系數(shù)(以管徑為基數(shù))。 </p> <p> <p> 二、風(fēng)道內(nèi)壓力的測(cè)定 </p> <p> (一)原理 </p> <p> 測(cè)量風(fēng)道中氣體的壓力應(yīng)在氣流比較平穩(wěn)的管段進(jìn)行。測(cè)試中需測(cè)定氣體的靜壓、動(dòng)壓和全壓。測(cè)氣體全壓的孔口應(yīng)迎著風(fēng)道中氣流的方向，測(cè)靜壓的孔口應(yīng)垂直于氣流的方向。用U形壓力計(jì)測(cè)全壓和靜壓時(shí)，另一端應(yīng)與大氣相通(用傾斜微壓計(jì)在正壓管段測(cè)壓時(shí)，管的一端應(yīng)與大氣相通，在負(fù)壓管段測(cè)壓時(shí)，容器開(kāi)口端應(yīng)與大氣相通)。因此壓力計(jì)上讀出的壓力，實(shí)際上是風(fēng)道內(nèi)氣體壓力與大氣壓力之間的壓差(即氣體相對(duì)壓力)。大氣壓力一般用大氣壓力表測(cè)定。由于全壓等于動(dòng)壓與靜壓的代數(shù)和，可只測(cè)其中兩個(gè)值，另一值通過(guò)計(jì)算求得。 </p> <p> <br /> </p> </p> <p> <br /> 通風(fēng)管道都有哪幾種？婺城區(qū)口碑好通風(fēng)管道</p><p style="text-indent:25px">常用材質(zhì)通風(fēng)管道有什么不同點(diǎn)？婺城區(qū)口碑好通風(fēng)管道</p><p> (二)測(cè)定儀器 </p> <p> 氣體壓力(靜壓、動(dòng)壓和全壓)的測(cè)量通常是用插入風(fēng)道中的測(cè)壓管將壓力信號(hào)取出，在與之連接的壓力計(jì)上讀出，常用的儀器有畢托管和壓力計(jì)。 </p> <p> 1 畢托管 </p> <p> (1)標(biāo)準(zhǔn)畢托管 </p> <p> 它是一個(gè)彎成90°的雙層同心圓管，其開(kāi)口端同內(nèi)管相通，用來(lái)測(cè)定全壓；在靠近管頭的外壁上開(kāi)有一圈小孔，用來(lái)測(cè)定靜壓，按標(biāo)準(zhǔn)尺寸加工的畢托管校正系數(shù)近似等于1。標(biāo)準(zhǔn)畢托管測(cè)孔很小，易被風(fēng)道內(nèi)粉塵堵塞，因此這種畢托管只適用于比較清潔的管道中測(cè)定。 </p> <p> (2)S型畢托管 </p> <p> 它是由兩根相同的金屬管并聯(lián)組成，測(cè)量時(shí)有方向相反的兩個(gè)開(kāi)口，測(cè)定時(shí)，面向氣流的開(kāi)口測(cè)得的相當(dāng)于全壓，背向氣流的開(kāi)口測(cè)得的相當(dāng)于靜壓。由于測(cè)頭對(duì)氣流的影響，測(cè)得的壓力與實(shí)際值有較大誤差，特別是靜壓。因此，S型畢托管在使用前須用標(biāo)準(zhǔn)畢托管進(jìn)行校正，S型畢托管的動(dòng)壓校正系數(shù)一般在0.82～0.85之間。S型畢托管測(cè)孔較大，不易被風(fēng)道內(nèi)粉塵堵塞，這種畢托管在含塵污染源監(jiān)測(cè)中得到廣泛應(yīng)用。
