運(yùn)用管道開孔與共振腔相連接，運(yùn)用小孔處的空氣柱和空腔內(nèi)的空氣構(gòu)成了彈性共振體系，當(dāng)外界噪聲頻率和此共振體系的固有頻率相同時(shí)，小孔中的空氣柱發(fā)作共振并與孔壁發(fā)作劇烈矛盾，矛盾能夠耗費(fèi)聲能。該消聲器有較強(qiáng)的頻率挑選性，一般關(guān)于低頻消聲能夠發(fā)生較大的衰減。 </p> <p> 3、抗性消聲器 </p> <p> 由管和小室相連而成，該消聲器使運(yùn)用風(fēng)管截面的忽然改變而使聲波向聲源方向反射回去而起到消聲效果。該消聲器對中、低噪聲有較好的消聲效果，結(jié)構(gòu)簡略，因?yàn)椴贿\(yùn)用吸聲材料，因此不受高溫文腐蝕性氣體的影響。消除低頻噪聲有必定效果。 </p> <p> 4、復(fù)合型消聲器 </p> <p>

新型安全門消音器采用了通孔噴、阻的消聲原理，其中以大孔擴(kuò)容控流代替微孔穿板型，在結(jié)構(gòu)上首先保證安全門排汽必須順暢的原理，多層次穿孔吸聲，并結(jié)合了阻性消聲原理，讓蒸汽聲波進(jìn)入多孔吸聲材料中的無數(shù)小孔內(nèi)，激發(fā)多孔材料分子震動，使聲能為了克服摩擦阻力和粘滯力而變成熱能，即達(dá)到了理想的消聲效果，更保證了蒸汽順利排除。 </p><p style="text-indent:25px">排氣式消聲器系綜合了比較合理的消聲原理所設(shè)計(jì)。高壓蒸汽在排氣消聲器內(nèi)經(jīng)一次控流后進(jìn)入降壓體經(jīng)大容積擴(kuò)壓后，從而形成低壓蒸汽后噴出，在此過程中，汽流內(nèi)能部分轉(zhuǎn)化成某種頻率的聲能，其噪聲雖然功率大為削弱，但往往會因排氣偏離設(shè)計(jì)值等原因。主要作用編輯降低發(fā)動機(jī)的排氣噪聲，并使高溫廢氣能安全有效地排出。消聲器作為排氣管道的一部分，應(yīng)保證其排氣暢通、阻力小及足夠強(qiáng)度。消聲器要經(jīng)受500℃~700℃高溫排氣，保證在汽車規(guī)定的行駛里程內(nèi)，不損壞、不失去消聲效果。汽車噪聲主要來自汽車排氣噪聲。若不加消聲器，噪聲可達(dá)100分貝以上。其次為引擎噪聲和輪胎噪聲，引擎噪聲在汽車正常運(yùn)轉(zhuǎn)時(shí)，可達(dá)90分貝以上，而輪胎噪聲在車速為90公里/時(shí)以上時(shí)，可達(dá)95分貝左右。因此，在排氣系統(tǒng)中加上消聲器，可使汽車排氣噪聲降低20-30分貝。在引擎方面，以汽油引擎代替柴油引擎，可以降低引擎噪聲6-8分貝氣流在消音器內(nèi)發(fā)生一種附加的再生噪聲。</p><div

1、消聲的效果要好，而且安全閥排氣消聲器的降噪量。 </p> <p> 2、安全閥排氣消聲器阻力要小，而且不能影響安全閥的排量和起跳回座的工作。 </p> <p> 3、在安全閥后面的排氣彎管和疏水盤以及排氣管和消聲器的整個排氣的系統(tǒng)要進(jìn)行的嚴(yán)格的設(shè)計(jì)，一般都是要成套的進(jìn)行設(shè)計(jì)和配套的，要保證消聲器對安全閥的整個性能不受到影響，疏水盤沒有出現(xiàn)倒冒氣。風(fēng)機(jī)消聲器是一種專業(yè)的消聲設(shè)備，它降噪的效果是非常突出的，可以說是目前比較為先進(jìn)的消聲設(shè)備了。連云港管道消音器哪家價(jià)格優(yōu)惠</p><p
