風(fēng)機是一種通用機械設(shè)備，其使用范圍很廣，電力、礦山、機械、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，連云港消音器哪個公司便宜，其進(jìn)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。 </p> <p> 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，連云港消音器哪個公司便宜。因此常規(guī)型通風(fēng)排氣消聲器，連云港消音器哪個公司便宜，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。低頻噪音指頻率低于500赫茲(八度)的聲音。連云港消音器哪個公司便宜</p><div

現(xiàn)在咱們首要說的就是安全閥排氣消聲器，排汽就是為了防止過大的噪聲，應(yīng)該讓氣流順利的排出，不影響安全閥的起跳和回座，之前運用的多級節(jié)省及小孔噴注的消聲方法是不合適的，因為這樣的產(chǎn)品首要帶來的就是在設(shè)計方面遇到了很多的問題，這也就是為什么安全閥排氣消聲器消聲效果差的原因。 </p> <p> 在這樣的前提條件下可以經(jīng)過技術(shù)革新和不斷的發(fā)明，新式安全閥的消聲器采用了抗、噴、阻的消聲原理，運用大孔擴容取代了以往直徑較小的控流孔，在結(jié)構(gòu)上更強化了之前的消聲機理，達(dá)到了理想的消聲效果，克服了之前消聲器在設(shè)計上面的困難，真實的滿足實際工業(yè)的運用需求。連云港鍋爐點火排汽消音器哪個公司便宜利用降壓的方式來吸收聲音，基本上可以達(dá)到40分貝左右。</p><div

空氣管道消音器是主要建立在“小孔噴注”理論結(jié)合阻抗擴容吸聲的消音原理，鍋爐蒸汽排放一般流速快，氣流噪聲高，需先以通孔擴流，經(jīng)過多次通孔后的蒸汽在抗性擴張室得到降壓降流，氣流再經(jīng)小孔噴出，噴出后其各倍頻帶的聲功率已降低，而聲壓級的頻率被推高到20000Hz以上范圍，其噪聲大為削弱，但部分頻率的二次噪音還需要進(jìn)一步消音，我們在擴張室外加裝阻性吸聲棉結(jié)構(gòu)，它系根據(jù) 降壓體所發(fā)出的剩余噪聲的頻譜特性所設(shè)計，用以有效地吸收剩余噪聲。當(dāng)用戶按要求安裝后，消音量可達(dá)30-42分貝。使之達(dá)到工業(yè)企業(yè)噪聲標(biāo)準(zhǔn)要求。 </p> <p> 空氣管道消音器也是一種利用渦流消音原理的消音器，與馬克沁消音器的區(qū)別是將膜片換成螺旋片，螺旋片中心開有彈頭通道。 </p> <p> 吸熱消音原理 </p> <p> 在空氣管道消音器內(nèi)裝有吸聲或吸熱材料，當(dāng)伙藥燃?xì)馔ㄟ^時，部分能量被這些材料吸收，使伙藥燃?xì)饫鋮s、減壓，從而降低搶口噪聲。吸熱體多采用銅、鋁等導(dǎo)熱性能好的材料，有的用金屬網(wǎng)纏繞或利用金屬絲、金屬屑壓成一定的密度和形狀。由于吸熱材料的溫度上升很快，故吸熱消音原理的消音器用于單發(fā)射擊消音效果很好，而用于連發(fā)射擊時消音效果不理想。 </p><p style="text-indent:25px">微孔板吸聲結(jié)構(gòu)的理論在板厚小于1.0mm的薄板上穿以孔徑小于等于1.0mm的微孔，穿孔率為1～5%，后部留有一定的厚度（5-20cm）空氣層，該層不填任何吸聲材料，這樣即構(gòu)成了微穿孔板吸聲結(jié)構(gòu)。它是一種低聲質(zhì)量，高聲阻的共振吸聲結(jié)構(gòu)，其研究表明，表征微穿孔板吸聲特性的吸聲系數(shù)和頻帶寬度，主要由微穿孔板的聲質(zhì)量m和聲阻r來決定，而這兩個因素又與微孔直徑d及穿孔率p有關(guān)。微穿孔板吸聲結(jié)構(gòu)的相對聲阻抗Z（以空氣的特性阻抗ρC為單位）在使用風(fēng)機消聲器的過程當(dāng)中一定要定期對其進(jìn)行清理工作，一般半年左右就要進(jìn)行一次清理了。</p><div

style="text-indent:25px">連云港廣潤生產(chǎn)的管道吹掃放空消音器系綜合了合理的消聲原理所設(shè)計。高壓蒸汽在管道吹掃放空消音器內(nèi)經(jīng)一次控流后進(jìn)入降壓體經(jīng)大容積擴壓后，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，但往往會排汽偏離設(shè)計值但等諸原因，使噪聲仍然高于標(biāo)準(zhǔn)值。為此，在管道吹掃放空消音器降壓體外設(shè)計了一只雙層結(jié)構(gòu)的阻聲罩，根據(jù)降壓體所發(fā)出的剩余噪聲的頻譜特性所設(shè)計，用以有效地吸收剩余噪聲。消聲器材料挑選上面必定要注意是要耐高溫、高壓、避免生銹以及不簡單形成阻塞的狀況，比如說不銹鋼的原料。連云港安全閥消音器</p><p style="text-indent:25px">風(fēng)機消聲器在使用的時候要注意不能使其暴露在露天的環(huán)境當(dāng)中，如果安裝在室外的，比較好加裝一個防雨棚才行。連云港消音器哪個公司便宜</p><p style="text-indent:25px">江蘇省連云港市廣潤機械設(shè)備有限公司生產(chǎn)的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(jìn)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。連云港消音器哪個公司便宜</p><p
