style="text-indent:25px">抗性消聲器可以分為5種基本形式：擴(kuò)張室消聲器、共鳴型消聲器、干涉型消聲器，梅州消聲器有哪些品牌、損耗型消聲器和文氏型消聲器。消聲原理：擴(kuò)張室消聲器一是利用管道的裁面突變，即聲阻抗的變化使沿管道傳播的聲波向聲源方向反射回去；二是利用擴(kuò)張室和內(nèi)插管的長度，使向前傳播的波和管子不同界面反射的聲波差一個180度的相位、從而使二者振幅相等、相位相反，互相干涉，達(dá)到較理想的消聲效果。共鳴型消聲器常用于消除管道傳播的低頻(350Hz以下)噪聲。干涉型消聲器的消聲原理足將聲波分成兩路，在管道上裝設(shè)一排通管，使管道長度為通管長度的2倍，梅州消聲器有哪些品牌。管道長度等于要消除的聲波的波長，梅州消聲器有哪些品牌，那么通管的長度則為二分之一波長。這樣聲波當(dāng)通過兩種不同長度的途徑時，在管道與通管匯合處將產(chǎn)生振幅相等，位移相反的2種聲波，彼此互相干涉，從而降低噪聲。消聲器用于減小排氣脈動，并盡可能降低排氣噪聲。梅州消聲器有哪些品牌</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(qiáng)度和剛度。在消聲器前后加接變徑管。對于風(fēng)機(jī)消聲器，為減小機(jī)振動對消聲器的影響，消聲器不應(yīng)與風(fēng)機(jī)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(jī)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(jī)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(jī)接口尺寸。梅州消聲器有哪些品牌微穿孔消聲器不使用任何阻性吸聲填料，采用微穿小孔多空腔結(jié)構(gòu)逐級改變原氣流的聲頻。</p><div

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2.5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，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。</p><p style="text-indent:25px">風(fēng)機(jī)設(shè)計和選用的消聲器應(yīng)考慮下列問題：根據(jù)風(fēng)機(jī)噪聲頻譜特性與區(qū)域環(huán)境的允許噪聲頻率特性的差值，決定設(shè)計或選用消聲器的消聲頻率特性，即噪聲頻帶的衰減量。噪聲控制標(biāo)準(zhǔn)，要根據(jù)環(huán)境區(qū)域和等級，參考有關(guān)國家或部頒標(biāo)準(zhǔn)。風(fēng)機(jī)噪聲有關(guān)數(shù)據(jù)可由廠家提供，如資料不全，可進(jìn)行估算，要進(jìn)行實(shí)際測量，以便獲得準(zhǔn)確可靠的數(shù)據(jù)，取得較好的噪聲控制效果。設(shè)計和選用消聲器應(yīng)特別注意其阻力損失，如果消聲器的消聲量滿足消聲要求，阻力損失很大，那么該消聲器就不是一個好的消聲器。其次，要避免消聲器的氣流消聲過大，工業(yè)用風(fēng)機(jī)消聲器的氣流速度應(yīng)控制在10-20m/s；消聲器宜安裝在風(fēng)機(jī)進(jìn)、出口，即離噪聲源較近，以防風(fēng)機(jī)噪聲激發(fā)管路振動；如消聲器裝在管路中，則氣流是穩(wěn)定的，消聲效果會好；對于降噪要求較高，需要裝幾個消聲器，消聲器宜分段安裝。另外，還要考慮消聲器的使用環(huán)境，如防水、防塵、防霉等，否則，會影響消聲器的消聲性能。消聲器的體積是非常小的，可以直接安裝在排汽的管道中，同時重量也是相對來說比較輕的。</p><div
