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，佛山消聲器廠家，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，佛山消聲器廠家，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，佛山消聲器廠家，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。狀消聲器的外罩是用圓形心棒將外罩材料成型并咬合或用焊接連接整體安裝，并將焊接的部件裝入接口。佛山消聲器廠家</p><div

style="text-indent:25px">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。發(fā)現(xiàn)覆面材料有破損現(xiàn)象，應根據(jù)情況及時修復或更換。消聲片敷設的消聲材料容易下沉，出現(xiàn)空隙而影響吸聲效果。制作時對容積較大的吸聲片可在容腔內(nèi)裝設適當?shù)耐袚醢?，搬運及安裝時應輕拿輕放。安裝前應進行檢查，消聲材料不得有明顯下沉。消聲器外殼拼接處及角部易產(chǎn)生孔洞而漏風，制作時應加以注意，發(fā)現(xiàn)孔洞后應及時用錫焊或密封膠堵嚴。穿孔板經(jīng)鉆孔后產(chǎn)生的毛刺易劃破覆面材料或產(chǎn)生噪音，應將孔口的毛刺銼平。消聲材料填充不均勻、覆面層不緊，消聲孔分布不均勻、孔徑小、總面積不足等使性能降低，要根據(jù)設計或規(guī)范嚴格工藝操作。消聲彎頭弧形片的弧度不均勻、消聲片片距不相等，應認真執(zhí)行工藝標準，缺陷予以消除。</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。風機消聲器根據(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)。柳州消聲器哪家便宜</p><p
