style="text-indent:25px">消聲器的安裝應(yīng)注意以下問題：消聲器的接口要牢靠。消聲器往往安裝在設(shè)備或管道上，消聲器與設(shè)備或管道的連接一定要牢靠，重量大的消聲器應(yīng)支撐在專門的承重架上，若管道為支撐架，必須注意支撐的強(qiáng)度和剛度。在消聲器前后加接變徑管。對(duì)于風(fēng)機(jī)消聲器，為減小機(jī)振動(dòng)對(duì)消聲器的影響，消聲器不應(yīng)與風(fēng)機(jī)接口直接連接，陽(yáng)江消聲器價(jià)格，而應(yīng)加設(shè)中間管道，陽(yáng)江消聲器價(jià)格。一般情況下，該中間管道長(zhǎng)度應(yīng)為風(fēng)機(jī)接口直徑的3-4倍。當(dāng)選用的消聲器的接口尺寸與風(fēng)機(jī)接口不同時(shí)，可以在消聲器前后加接變徑管。消聲器接口尺寸應(yīng)大于風(fēng)機(jī)接口尺寸，陽(yáng)江消聲器價(jià)格。在連接螺套里裝有油浸石棉密封圈，以防止排氣管和消聲筒之間的接口漏氣。陽(yáng)江消聲器價(jià)格</p><div

style="text-indent:25px">消聲器的優(yōu)點(diǎn)：消聲的聲量**量的蒸汽一同排放出去的時(shí)候，它們產(chǎn)生的噪聲分貝是非常高的，沒有聽過的人們應(yīng)該是無法想象的。而消聲器能夠消除的噪聲范圍在28dBA以上，這個(gè)是還只是平均的數(shù)值而已。消聲器的體積是非常小的，可以直接安裝在排汽的管道中，同時(shí)重量也是相對(duì)來說比較輕的。無論是安裝，還是后續(xù)的檢查維修工作都是非常方便的。消聲器的品種類型多，可以適用于不同規(guī)格的機(jī)器，同時(shí)可以按照實(shí)際的情況來選擇不同的品種，讓其在它們的工作中發(fā)揮各自的優(yōu)勢(shì)。主要的品種有小孔型、通孔型等等，選擇的類型非常多。消聲器，從它的材料的選擇上面就能知曉其的穩(wěn)定性，使用壽命非常的長(zhǎng)久，較長(zhǎng)的實(shí)效可以達(dá)到30年的時(shí)間。選擇一個(gè)安裝，就無需擔(dān)心會(huì)在運(yùn)行的過程中快速的被銷毀的情況。陽(yáng)江消聲器價(jià)格有源式消聲器基是使其在一定范圍內(nèi)與原來的聲場(chǎng)相抵消。</p><div

style="text-indent:25px">盤式消聲器的形狀類似圓盤，具有較小的長(zhǎng)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(chǎng)條件和空間不容許安裝較長(zhǎng)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(jìn)風(fēng)、排風(fēng)作用。小室式消聲器優(yōu)點(diǎn)是消聲頻帶較寬，消聲量較大；缺點(diǎn)是阻力損失較大，占用空間也大，一般適用于低速進(jìn)、排風(fēng)消聲。從吸聲原理上講，阻性消聲器對(duì)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(qiáng)，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">直管消聲器消聲量的計(jì)算:直管式消聲器消聲量主要與通道形式、長(zhǎng)度和吸聲材料的性能有關(guān)。消聲量的計(jì)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(zhǎng)(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(zhǎng)度，或增加通道周長(zhǎng)與截面積的比P/S，消聲量越大。同樣周長(zhǎng)，圓形截面的周長(zhǎng)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(dāng)直管消聲器截面較大時(shí)，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”。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。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="陽(yáng)江消聲器價(jià)格,消聲器"

style="text-indent:25px">消聲器的原理：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。在連接螺套里裝有油浸石棉密封圈，以防止排氣管和消聲筒之間的接口漏氣。消聲筒內(nèi)焊有7塊隔板，將消聲筒分成8個(gè)消聲腔（七個(gè)膨脹室和一個(gè)共振腔）在筒芯上面有倒三角形導(dǎo)流槽和許多小孔，當(dāng)發(fā)動(dòng)機(jī)的高溫廢氣以高速經(jīng)排氣管進(jìn)入消聲器時(shí)，由于消聲筒的截面積逐漸增大，氣流得以膨脹，流速降低，強(qiáng)大的脈動(dòng)噪聲得以衰減。當(dāng)氣流繼續(xù)流經(jīng)各膨脹室時(shí)，由于隔板的阻擋，氣流只能從隔板上的節(jié)流了、及筒芯通過，于是氣流突然被壓縮，分成許多細(xì)流，后又突然得以膨脹，如此多次突變，聲能被有效衰減，從而起到降低排氣噪聲的作用。消聲器用于減小排氣脈動(dòng)，并盡可能降低排氣噪聲。陽(yáng)江消聲器價(jià)格</p><p style="text-indent:25px">干涉型消聲器適用于消減某保持不變的單一頻率的噪聲。陽(yáng)江消聲器價(jià)格</p><p style="text-indent:25px">風(fēng)速變化很大的通風(fēng)系統(tǒng)消聲器安裝方法：變徑后直接安裝消聲器，則該處氣流渦流增大，通風(fēng)系統(tǒng)阻力增大。消聲器進(jìn)口處中心區(qū)域氣流來不及充分衰減，直接沖入消聲器，則此時(shí)消聲器內(nèi)實(shí)際的氣流速度遠(yuǎn)大于消聲器的設(shè)計(jì)氣流速度。則消聲器的實(shí)際有效長(zhǎng)度降低，消聲器實(shí)際效果遠(yuǎn)不能達(dá)到設(shè)計(jì)要求。正確的做法是將變徑后的風(fēng)管延長(zhǎng)直徑的5~8倍后，氣流達(dá)到穩(wěn)態(tài)時(shí)狀況再安裝消聲器，此時(shí)消聲器才能達(dá)到設(shè)計(jì)效果。隨著我國(guó)經(jīng)濟(jì)的快速發(fā)展，人們對(duì)建筑物的要求越來越高，暖通工程作為工程項(xiàng)目的重要組成部分，其施工質(zhì)量的好差將直接影響到建筑物的使用功能，這就要求有關(guān)工程技術(shù)人員嚴(yán)把暖通工程的施工質(zhì)量，這樣才能夠避免使用過程中盡量不出問題或少出問題，一旦出現(xiàn)問題可以減少維修費(fèi)用，節(jié)約人力物力，節(jié)省社會(huì)資源。陽(yáng)江消聲器價(jià)格</p><p
