style="text-indent:25px">阻抗聲流型通風、排氣管道及風機消聲器結構原理：根據(jù)對工業(yè)用各類風機運行現(xiàn)場噪聲源進行實際測試所取得的頻譜特性資料來確定在哪些頻譜范圍內(nèi)需要多大消聲量作為設計吸聲體及流體通道的主要依據(jù)，同時采用了具有較大吸聲材料飾面的狹矩形通道，以增強吸收效果。另，風機的噪聲源在較大噪聲級時，其頻譜值往往不止一種，而對不同頻譜帶，對其消聲量要求也不相同。為此系列通風管道消音器及鼓引風機消聲器均為阻抗聲流型，采用了對高，賀州消聲器多少錢一個、中頻噪聲起吸音消聲作用的阻式結構及對中，賀州消聲器多少錢一個、低頻噪聲起消聲降音作用的抗式結構，同時在阻式通道中采用了高頻及低頻兩種吸音消聲區(qū)，用以較大限度的增寬消聲頻帶，以實現(xiàn)良好的消聲降噪效果，賀州消聲器多少錢一個。盤式消聲器的形狀類似圓盤，具有較小的長度。賀州消聲器多少錢一個</p><div

style="text-indent:25px">消聲器的消聲原理是利用腔與管的適當組合，來達到兩種作用來消聲的：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；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，從而互相干涉而抵消。風機式消聲器主要適用于降低羅茨系列、軸流系列風機的進排氣噪聲，也可以用于對排氣管道及其它高壓風機的降噪，消聲量15-30dB，壓力損失少于500Pa。佛山消聲器哪家強消聲器能吸收排管的垂直和水平熱位移，保證排氣。</p><div

style="text-indent:25px">阻抗復合式消聲器組裝時，應先用圓釘將制成的消聲片裝釘成消聲片組，同時用鉚釘將橫隔板與內(nèi)管分段鉚接好，然后用半圓頭木螺絲將各段內(nèi)管與消聲片組固定，再將外管與橫隔板、外管與消聲器兩端蓋板、蓋板與內(nèi)管分別用半沉頭自攻螺絲固定，之后在鉚接兩端法蘭。消聲彎管的平面邊長大于800mm時，應加設導流吸聲片。導流吸聲片表面應平滑、圓弧均勻、與彎管連接緊密牢固。不得有松動現(xiàn)象。消聲百葉窗，框架應牢固，葉片的片距應均勻，吸聲面方向應符合設計要求。消聲器內(nèi)外金屬構件表面應涂刷紅丹防銹漆兩道（較好鍍鋅板材可不涂防銹漆）。涂刷前，金屬表面應按需要做好處理，去除鐵銹、油脂等雜物。涂刷時要求無漏涂、起泡、露底等現(xiàn)象。</p><p style="text-indent:25px">消聲器適用于鍋爐等蒸汽設備的TB型點火排氣，TB型鍋爐點火排汽消聲器綜合了PB型排汽（氣）消聲器較合理的消聲原理所設計。高壓蒸汽在消聲器內(nèi)經(jīng)一次控流后進入降壓體，經(jīng)大容積再次擴容降壓后，往往會因排汽偏離設計值等諸多原因，使排氣噪聲仍然高于標準值。為此，在降壓體外設計了組合型多材料復合結構的阻聲吸音罩，復合阻聲吸音罩是根據(jù)降壓體所噴出的剩余噪聲的頻譜特性所設計，用以有效地吸收剩余噪聲。當用戶按要求安裝后，總消聲量可達36～42分貝。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。</p><div

style="text-indent:25px">有源式消聲器基是使其在一定范圍內(nèi)與原來的聲場相抵消。賀州消聲器多少錢一個</p><p style="text-indent:25px">風機消聲器分為：離心風機消聲器、羅茨風機消聲器、鼓風機消聲器、軸流風機消聲器。風機消聲器主要用于降低各種風機風口、風道和封閉式機房進風口的空氣動力性噪聲。根據(jù)風機進出口結構不同，分為圓形結構和矩形結構。圓形結構分用于風機接管口為圓形,又分為A、B型兩種， A型兩端均為法蘭盤，直接串接于管道中(即管道消聲器)， B型一端為法蘭，另一端為直接大氣排空(可裝防雨風帽)，*供設置在室外管道末端和封閉式機房進風口選用。由于風盤出口風速一般大于進口，故風量一定時，進風口面積要比出風口的大。若進出風口裝反了，風量會降低，但出風溫度會升高。制熱效果差，可能風盤選型有問題，更可能水流量出現(xiàn)問題，如過濾器堵塞、管道積氣，流經(jīng)盤管的水量少于額定量，都會導致制熱效果差。賀州消聲器多少錢一個</p><p
