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(jié)構(gòu)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。</p><p style="text-indent:25px">評價消聲器聲學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。消聲器成品應在平整、無積水的室內(nèi)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">直管消聲器消聲量的計算:直管式消聲器消聲量主要與通道形式、長度和吸聲材料的性能有關。消聲量的計算公式為：其中，Φ是消聲系數(shù)，即每米消聲量(dB/m)；P是消聲器通道截面周長(m)；S是消聲器通道截面積(m2)。消聲管道內(nèi)吸聲系數(shù)越大，消聲系數(shù)Φ越大，消聲量越高。增加長度，或增加通道周長與截面積的比P/S，消聲量越大。同樣周長，圓形截面的周長與截面積的比，要比扁狀的矩形小很多，因此，圓形截面的直管式消聲器消聲性能小。當直管消聲器截面較大時，如徑尺寸大于30cm的圓管或矩形管，高頻聲波成上束狀，將直接穿過管道，而與管壁的吸聲材料不發(fā)生作用，消聲性能變差，這種高頻性能下降的現(xiàn)象被稱為“高頻失效”。并將高頻消聲量明顯下降的頻率稱為“上限失效頻率”。片式消聲器適合較大風量和較大管道情況使用。北海消聲器制造商</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(jié)構(gòu)不同，分為圓形結(jié)構(gòu)和矩形結(jié)構(gòu)。圓形結(jié)構(gòu)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。北海消聲器制造商</p><p
