style="text-indent:25px">氣缸消聲器的定義：消音器是一種允許氣流通過而能使聲能衰減的裝置，能夠降低氣流通道上的空氣動力性噪聲。氣缸消聲器的選擇方法：具有較好的消聲性能，即要求消聲器具有較好的消聲頻率特性，噪聲一般控制在74~80dB之間(當供氣為0，潮州消聲器哪家強.6MPa,距離為1m時測得的噪聲）具有良好的空氣動力性能，消聲器對氣流的阻力損失要小結構簡單，便于加工，經濟耐用，潮州消聲器哪家強，無再生噪聲，潮州消聲器哪家強。在設計和選擇消聲器時，應合理選擇通過消聲器的氣流速度。對空調系統(tǒng)，流過的氣流速度可取≤6m/s;對一般系統(tǒng)宜取6~10m/s;對工業(yè)鼓風機或其他氣動設備可取10~20m/5s;對高壓排空消聲器則可大于20m/s。筒式消聲器一般由排氣管、連接螺套、消聲筒和筒芯等幾部分組成。潮州消聲器哪家強</p><div

style="text-indent:25px">消聲器的工作原理主要是讓推動彈丸做功的燃氣在一個相對于管要大得多的封閉空間內釋放熱能，以減少壓強和流速，避免對口附近的空氣產生過大的沖擊（也就是產生口噪音——發(fā)射時的主要噪音）。現(xiàn)在世界上通用的消音器其原理基本上是通過降低燃氣沖出口的速度和流量來降低較大峰值來消音。具體的措施是，在消音器內裝上若干帶有小孔的消音隔板或鋼絲，或在口安裝一個口徑比小的橡膠消音器等等來降低口的較大峰值（也就是提前將燃氣要做的功傾瀉掉），同時使用低于音速的彈（低速彈）降低在空氣中飛行的呼嘯聲。不管你用什么方法來降低的聲音，總是要**的一些性能，同時使自動機工作不正常。所以消音器并沒有什么制退的作用，也不會減小后坐力?，F(xiàn)在的一般在膛口處加裝了籠型或桶型消焰器，通過改變排焰孔的切削角度可以實現(xiàn)一定的制退作用，但是裝上消音器后膛口裝置的制退作用也消失了。消音器除了通常的消音和消焰作用外，還有一個附加的好處——在膛口處增加了一個重物，可以抑止口上跳，減少散布提高精度。潮州消聲器哪家強消聲器的消聲量越大，壓力損失及價格越大。</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，好像是一個聲學濾波器，與電學濾波器相似，每一個帶管的小室是濾波器的一個網孔，管中的空氣質量相當于電學上的電感和電阻，稱為聲質量和聲阻。小室中的空氣體積相當于電學上的電容，稱為聲順。與電學濾波器類似，每一個帶管的小室都有自己的固有頻率。當包含有各種頻率成分的聲波進入個短管時，只有在個網孔固有頻率附近的某些頻率的聲波才能通過網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構為聲學濾波器。選取適當的管和室進行組合．就可以濾掉某些頻率成分的噪聲，從而達到消聲的目的。抗性消聲器適用于消除中、低頻噪聲。</p><p 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）；消聲器的結構性能。（尺寸、價格、壽命等）；消聲器的消聲頻率特性。抗噴阻型消聲器對各頻噪聲效果優(yōu)越。消聲器的適用風速一般為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，風管和消聲器連接時，必要時（風速有限制時）需作放大處理。消聲器等消聲設備安裝，須有**的承重吊桿或底座與聲源設備須通過軟接頭連接。當兩個消聲彎頭串聯(lián)使用時，兩個彎頭的連接間距應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)一般選用微孔結構消聲設備，對于有潔凈要求的諸如手術室、錄音室、潔凈廠房等環(huán)境系統(tǒng)，應采用微孔結構消聲設備。相鄰用房管路串通時，注意室內噪聲通過管路相互影響，必要時風口作消聲處理。消聲器成品應在平整、無積水的室內場地上碼放整齊，下部設有墊托，并有必要的防水措施。</p><div

style="text-indent:25px">消聲器的選用與設置：對中、高頻噪聲源，宜采用阻性或復合型消聲器；對于低、中頻噪聲源，宜采用共振型消聲器、膨脹型消聲器等抗性消聲器；對于脈動低頻噪聲源、變頻帶噪聲源，宜采用抗性或微穿孔板阻抗復合式消聲器。確定空調系統(tǒng)所需消聲量后，根據具體情況選擇消聲器形式，之后，根據已知的風量、消聲器設計流速和消聲量，確定消聲器的種類、型號、數量。消聲器一般應設于空調機房和空調房間之間考近空調機房，且氣流穩(wěn)定的直管段上。消聲器的覆面材料容易破損，使吸聲材料外露或脫落，影響功能。制作時，釘覆面材料的泡釘應加墊片。潮州消聲器哪家強</p><p style="text-indent:25px">安全閥消聲器排汽消聲器可達25分貝以上。潮州消聲器哪家強</p><p style="text-indent:25px">消聲器的機殼或管道輻射的噪聲可能傳入消聲器后端，致使消聲效果下降，必要時，可在消聲器外殼或部分管道上做隔聲處理。消聲器法蘭和風機法蘭連接處應加彈性墊并注意密封，以免漏聲、漏氣，同時也能減少剛性連接的振動傳聲。在通風空調系統(tǒng)中，消聲器應盡量安裝于靠近使用房間的地方。消聲器片間流速應適當。風機消聲器片間平均流速可認為與風機管道流速相等。用于民用建筑，消聲器片間流速通常取3-12m/s；工業(yè)方面，消聲器片間流速通常取12-25m/s，較大不得超過30m/s。流速不同，消聲器護面結構應不同。平均流速小于10m/s時，多孔吸聲材料的護面可用防火布或金屬絲網罩起來；平均流速為10-23m/s時，可選用金屬穿孔板護面；當平均流速為23-45m/s時，可選用玻璃絲布和金屬穿孔板護面；當平均流速為45-120m/s時，可采用雙層金屬穿孔板和鋼絲棉護面，穿孔率應大于20%。潮州消聲器哪家強</p><p
