style="text-indent:25px">風(fēng)機設(shè)計和選用的消聲器應(yīng)考慮下列問題：根據(jù)風(fēng)機噪聲頻譜特性與區(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)機噪聲有關(guān)數(shù)據(jù)可由廠家提供，如資料不全，可進行估算，要進行實際測量，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)機進、出口，即離噪聲源較近，以防風(fēng)機噪聲激發(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。肇慶消聲器供應(yīng)公司干涉型消聲器適用于消減某保持不變的單一頻率的噪聲。</p><div

style="text-indent:25px">盤式消聲器的形狀類似圓盤，具有較小的長度，氣流和聲波通過圓盤四周輻射，適合于在某些情況下，現(xiàn)場條件和空間不容許安裝較長形狀的消聲器。彎頭式消聲器是一種氣流管道彎曲的消聲器，多用于房間里的通風(fēng)空調(diào)進風(fēng)、排風(fēng)作用。小室式消聲器優(yōu)點是消聲頻帶較寬，消聲量較大；缺點是阻力損失較大，占用空間也大，一般適用于低速進、排風(fēng)消聲。從吸聲原理上講，阻性消聲器對中、高頻噪聲的消除效果較好；但隨著頻率升高，高頻聲波的方向性越來越好，集束性越來越強，聲波以窄束狀通過消聲器，而與吸聲材料的接觸率有效減少，導(dǎo)致消聲量明顯下降。</p><p style="text-indent:25px">CF型風(fēng)機消音器：風(fēng)機是一種通用機設(shè)備，其使用范圍很廣，電力、礦山、機、冶金、化工等各行業(yè)的生產(chǎn)均離不開風(fēng)機。風(fēng)機在運轉(zhuǎn)中產(chǎn)生的噪聲常常成為影響工人健康和干擾環(huán)境的禍源。特別是鄰近生活區(qū)的風(fēng)機，其進風(fēng)口和出風(fēng)口所輻射的空氣動力性噪聲，更是污染環(huán)境的主要因素，形成公害，是我國工業(yè)部門治理噪聲污染的主要對象之一。CP型柴油發(fā)電機排氣消聲器，柴油發(fā)電機以其良好的經(jīng)濟性和動力性能，被普遍用于工礦企業(yè)生產(chǎn)經(jīng)營中，因其在運行過程排放的煙氣中含有一定量的煙塵（也就是大家經(jīng)常見到的黑煙），其現(xiàn)象是由于燃油燃燒不完全而產(chǎn)生的。因此常規(guī)型通風(fēng)排氣消聲器，如微孔板式消聲器和帶有吸音填料的消音器要是使用在這種環(huán)境下，是絕不可取的,原因是其只能起到一時的消聲降音。微穿孔消聲器耐高溫、耐高速氣流沖擊。</p><div

style="text-indent:25px">阻性式消聲器：主要是利用多孔吸聲材料來降低噪聲的。把吸聲材料固定在氣流通道的內(nèi)壁上或按照一定方式在管道中排列，就構(gòu)成了阻性消聲器。當(dāng)聲波進入阻性消聲器時，一部分聲能在多孔材料的孔隙中摩擦而轉(zhuǎn)化成熱能耗散掉，使通過消聲器的聲波減弱。阻性消聲器就好象電學(xué)上的純電阻電路，吸聲材料類似于電阻。因此，人們就把這種消聲器稱為阻性消聲器。阻性消聲器對中高頻消聲效果好、對低頻消聲效果較差。把阻性結(jié)構(gòu)和抗性結(jié)構(gòu)按照一定的方式組合起來，就構(gòu)成了阻抗復(fù)合式消聲器。吸收式消聲器：通過廢氣在玻璃纖維、鋼纖維和石棉等吸音材料商的摩擦而減少其能量。肇慶消聲器供應(yīng)公司</p><p
