style="text-indent:25px">衡量消聲器的好壞，主要考慮以下三個方面：消聲器的消聲性能；（消聲量和頻譜特性）；消聲器的空氣動力性能；（壓力損失等）；消聲器的結(jié)構(gòu)性能。（尺寸、價格、壽命等）；消聲器的消聲頻率特性?？箛娮栊拖暺鲗Ω黝l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12m/s，同時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，必要時（風(fēng)速有限制時）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)備須通過軟接頭連接。當(dāng)兩個消聲彎頭串聯(lián)使用時，兩個彎頭的連接間距應(yīng)大于彎頭截面對角線長度的2，河源消聲器工廠.5倍。對于高溫、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，河源消聲器工廠，對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，注意室內(nèi)噪聲通過管路相互影響，必要時風(fēng)口作消聲處理。蒸汽消聲器體積小，河源消聲器工廠，重量輕，安裝簡便，易維護。河源消聲器工廠</p><div

style="text-indent:25px">消聲器的安裝應(yīng)注意以下問題：消聲器的接口要牢靠。消聲器往往安裝在設(shè)備或管道上，消聲器與設(shè)備或管道的連接一定要牢靠，重量大的消聲器應(yīng)支撐在專門的承重架上，若管道為支撐架，必須注意支撐的強度和剛度。在消聲器前后加接變徑管。對于風(fēng)機消聲器，為減小機振動對消聲器的影響，消聲器不應(yīng)與風(fēng)機接口直接連接，而應(yīng)加設(shè)中間管道。一般情況下，該中間管道長度應(yīng)為風(fēng)機接口直徑的3-4倍。當(dāng)選用的消聲器的接口尺寸與風(fēng)機接口不同時，可以在消聲器前后加接變徑管。消聲器接口尺寸應(yīng)大于風(fēng)機接口尺寸。貴港消聲器定做小孔消聲器使頻譜中的可聽聲成分明顯降低，從而減少對人的干擾和傷害。</p><div

style="text-indent:25px">抗性式消聲器是由突變界面的管和室組合而成的，好像是一個聲學(xué)濾波器，與電學(xué)濾波器相似，每一個帶管的小室是濾波器的一個網(wǎng)孔，管中的空氣質(zhì)量相當(dāng)于電學(xué)上的電感和電阻，稱為聲質(zhì)量和聲阻。小室中的空氣體積相當(dāng)于電學(xué)上的電容，稱為聲順。與電學(xué)濾波器類似，每一個帶管的小室都有自己的固有頻率。當(dāng)包含有各種頻率成分的聲波進入個短管時，只有在個網(wǎng)孔固有頻率附近的某些頻率的聲波才能通過網(wǎng)孔到達第二個短管口，而另外一些頻率的聲波則不可能通過網(wǎng)孔．只能在小室中來回反射，因此，我們稱這種對聲波有濾波功能的結(jié)構(gòu)為聲學(xué)濾波器。選取適當(dāng)?shù)墓芎褪疫M行組合．就可以濾掉某些頻率成分的噪聲，從而達到消聲的目的?？剐韵暺鬟m用于消除中、低頻噪聲。</p><p style="text-indent:25px">汽車消聲器的消聲原理是什么？汽車消聲器的消聲原理是利用腔與管的適當(dāng)組合，從而達到兩種作用來促成消聲效果的：汽車消聲器，一是利用管道截面突變(即聲抗的變化)使沿管道傳播的聲波向聲源方向反射回去，從而使聲能反射回原處；汽車消聲器二是利用幾個界面的反射，使原來個向前傳播的聲波又回到原點，并再次折回向前傳播，該點與尚未被反射的第二個向前傳播的聲波匯合，而且兩者在振幅上相等，在相位上差180度的奇數(shù)倍，從而互相干涉而被抵消。消聲器單獨固定，能滿足管道熱位移的要求。</p><div

style="text-indent:25px">CF型風(fēng)機消音器：風(fēng)機是一種通用機設(shè)備，其使用范圍很廣，電力、礦山、機、冶金、化工等各行業(yè)的生產(chǎn)均離不開風(fēng)機。風(fēng)機在運轉(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，其進風(fēng)口和出風(fēng)口所輻射的空氣動力性噪聲，更是污染環(huán)境的主要因素，形成公害，是我國工業(yè)部門治理噪聲污染的主要對象之一。CP型柴油發(fā)電機排氣消聲器，柴油發(fā)電機以其良好的經(jīng)濟性和動力性能，被普遍用于工礦企業(yè)生產(chǎn)經(jīng)營中，因其在運行過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的消聲降音。微穿孔消聲器阻力損失小，消聲頻帶寬，工作時不起塵。貴港消聲器定做</p><p

style="text-indent:25px">評價消聲器聲學(xué)性能好壞的量有下列4種：插入損失，在系統(tǒng)中，裝置消聲器以前和裝置消聲器以后相對比較，通過管口輻射噪聲的聲功級之差定義為消聲器的插入損失。傳聲損失。減噪量，在消聲器進口端面測得的平均聲壓級與出口端面測得的平均聲壓級之差稱為減噪量。衰減量，消聲器內(nèi)部兩點間的聲壓級的差值稱為衰減量，主要用來描述消聲器內(nèi)聲傳播的特性，通常以消聲器單位長度的衰減量（dB/m）來表征。傳聲損失和衰減量是屬于消聲器本身的特性，它受聲源與環(huán)境影響較小（不包括氣流速度的影響），而插入損失、減噪量不單是消聲器本身的特性，它還受到聲源端點反射以及測量環(huán)境的影響。河源消聲器工廠</p><p
