style="text-indent:25px">衡量消聲器的好壞，主要考慮以下三個(gè)方面：消聲器的消聲性能；（消聲量和頻譜特性）；消聲器的空氣動(dòng)力性能；（壓力損失等）；消聲器的結(jié)構(gòu)性能。（尺寸、價(jià)格、壽命等）；消聲器的消聲頻率特性。抗噴阻型消聲器對(duì)各頻噪聲效果優(yōu)越。消聲器的適用風(fēng)速一般為6-8m/s，較高不宜超過(guò)12m/s，同時(shí)注意消聲器的壓力損失。注意消聲器的凈通道截面積，風(fēng)管和消聲器連接時(shí)，必要時(shí)（風(fēng)速有限制時(shí)）需作放大處理。消聲器等消聲設(shè)備安裝，須有**的承重吊桿或底座與聲源設(shè)備須通過(guò)軟接頭連接。當(dāng)兩個(gè)消聲彎頭串聯(lián)使用時(shí)，兩個(gè)彎頭的連接間距應(yīng)大于彎頭截面對(duì)角線長(zhǎng)度的2.5倍。對(duì)于高溫、高濕、有油霧、水氣的環(huán)境系統(tǒng)一般選用微孔結(jié)構(gòu)消聲設(shè)備，對(duì)于有潔凈要求的諸如手術(shù)室、錄音室、潔凈廠房等環(huán)境系統(tǒng)，應(yīng)采用微孔結(jié)構(gòu)消聲設(shè)備。相鄰用房管路串通時(shí)，注意室內(nèi)噪聲通過(guò)管路相互影響，必要時(shí)風(fēng)口作消聲處理。江門消聲器價(jià)錢盤式消聲器的形狀類似圓盤，具有較小的長(zhǎng)度。</p><div

style="text-indent:25px">CF型風(fēng)機(jī)消音器：風(fēng)機(jī)是一種通用機(jī)設(shè)備，其使用范圍很廣，電力、礦山、機(jī)、冶金、化工等各行業(yè)的生產(chǎn)均離不開風(fēng)機(jī)。風(fēng)機(jī)在運(yùn)轉(zhuǎn)中產(chǎn)生的噪聲常常成為影響工人健康和干擾環(huán)境的禍源。特別是鄰近生活區(qū)的風(fēng)機(jī)，其進(jìn)風(fēng)口和出風(fēng)口所輻射的空氣動(dòng)力性噪聲，更是污染環(huán)境的主要因素，形成公害，是我國(guó)工業(yè)部門治理噪聲污染的主要對(duì)象之一。CP型柴油發(fā)電機(jī)排氣消聲器，柴油發(fā)電機(jī)以其良好的經(jīng)濟(jì)性和動(dòng)力性能，被普遍用于工礦企業(yè)生產(chǎn)經(jīng)營(yíng)中，因其在運(yùn)行過(guò)程排放的煙氣中含有一定量的煙塵（也就是大家經(jīng)常見到的黑煙），其現(xiàn)象是由于燃油燃燒不完全而產(chǎn)生的。因此常規(guī)型通風(fēng)排氣消聲器，如微孔板式消聲器和帶有吸音填料的消音器要是使用在這種環(huán)境下，是絕不可取的,原因是其只能起到一時(shí)的消聲降音。</p><p style="text-indent:25px">阻性消聲器的種類很多，按照氣流通道的幾何形狀可分為通道片式消聲器、通道拆板式消聲器、雙圓筒式消聲器、室式(迷宮式)消聲器、蜂窩狀消聲器、菱形消聲器、正弦波形消聲器及圓筒插管式消聲器。阻性消聲器的消聲原理是利用聲阻進(jìn)行消聲的，也就是說(shuō)，在推導(dǎo)消聲量的計(jì)算公式時(shí)，**考慮聲阻礙對(duì)消聲的貢獻(xiàn)，而忽略聲抗的影響。在實(shí)際工程中，常常利用吸聲材料來(lái)制作阻性消聲器，以達(dá)到降低噪聲的目的。這是由于當(dāng)聲波通過(guò)襯貼有多孔吸聲材料的管道時(shí)，聲波將激發(fā)多孔材料中無(wú)數(shù)小孔內(nèi)空氣分子的振動(dòng)。其中一部分聲能將用于克服摩擦阻力和粘滯力，而變?yōu)闊崮堋Ｒ话愕恼f(shuō)，阻性消聲器具有良好的中高頻消聲性能，而低頻性能則較差。然而只要適當(dāng)增加吸聲材料的厚度、密度以及選用較低的空隙率，低中頻消聲性能就能有效改善，從而可以做成寬頻帶阻性消聲器。消聲器成品應(yīng)在平整、無(wú)積水的室內(nèi)場(chǎng)地上碼放整齊，下部設(shè)有墊托，并有必要的防水措施。</p><div
