style="text-indent:25px">汽車消聲器的安裝：汽車消聲器在使用時，須至少浸入水面下300mm，且離容器的側(cè)壁與底部不小于200mm，較好放置于容器的幾何中心。選型時，管道的口徑應(yīng)大于或等于加熱器的公稱通徑，多個加熱器并聯(lián)使用時，蒸汽管道的截面積應(yīng)大于或等于所有的加熱器連接管截面積之和。蒸汽壓力大于0.5MPa（表壓）時，應(yīng)裝蒸汽減壓閥減壓，其前加裝過濾器。蒸汽管路上近加熱器處，須安裝止回閥，防止停汽時，發(fā)生虹吸現(xiàn)象，導(dǎo)致發(fā)生水倒流的事故。近加熱器的蒸汽管應(yīng)該牢靠結(jié)實的固定，使之工作時，不致于擺動。加熱器多臺并聯(lián)使用，宜均勻分布，因為重量較大，應(yīng)加以支撐，安裝定位視現(xiàn)場情況而定。水箱的水溫與水位，宜采用溫度控制儀與水位控制儀進(jìn)行測控。使用中如果加熱器加熱速度變慢，可能是其內(nèi)部汽孔被堵塞，世紀(jì)星介紹應(yīng)拆下加熱器將堵塞汽孔的雜質(zhì)去除干凈，并將污物從排污口排出，加熱器較好每個月清理一次。</p><p style="text-indent:25px">衡量消聲器的好壞，主要考慮以下三個方面：消聲器的消聲性能；（消聲量和頻譜特性）；消聲器的空氣動力性能；（壓力損失等）；消聲器的結(jié)構(gòu)性能。（尺寸、價格、壽命等）；消聲器的消聲頻率特性?？箛娮栊拖暺鲗Ω黝l噪聲效果優(yōu)越。消聲器的適用風(fēng)速一般為6-8m/s，較高不宜超過12m/s，同時注意消聲器的壓力損失。注意消聲器的凈通道截面積，風(fēng)管和消聲器連接時，必要時（風(fēng)速有限制時）需作放大處理。消聲器等消聲設(shè)備安裝，須有**的承重吊桿或底座與聲源設(shè)備須通過軟接頭連接。當(dāng)兩個消聲彎頭串聯(lián)使用時，兩個彎頭的連接間距應(yīng)大于彎頭截面對角線長度的2.5倍。對于高溫、高濕、有油霧、水氣的環(huán)境系統(tǒng)一般選用微孔結(jié)構(gòu)消聲設(shè)備，對于有潔凈要求的諸如手術(shù)室、錄音室、潔凈廠房等環(huán)境系統(tǒng)，應(yīng)采用微孔結(jié)構(gòu)消聲設(shè)備。相鄰用房管路串通時，注意室內(nèi)噪聲通過管路相互影響，必要時風(fēng)口作消聲處理。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">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(guān)。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(dāng)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”?？箛娮栊拖暺餍畔⑽曄禂?shù)高，吸收頻帶寬，壓力損失小，氣流再生噪聲低，且易于控制。來賓消聲器有哪些</p><p
