helvetica;color:#000000;font-size:14px;font-weight:400;">1、在氣動功能上要盡量減少氣流沖擊和附面層別離現象,以防止或減少沖擊噪聲和渦流噪聲的發作，設計時要防止通流部分尖利突出和急劇轉彎。</span><br /> <br /> <span style="line-height:2;font-style:normal;font-family:'sans serif', tahoma, verdana, helvetica;color:#000000;font-size:14px;font-weight:400;">2、利用聲的阻抗失配原理,在軸流風機進排氣口處設計和安裝消聲器,使軸流風機進、排氣口的聲輻射噪聲減至最小,能夠有效地下降噪聲。</span><br /> <br /> <span style="line-height:2;font-style:normal;font-family:'sans serif', tahoma, verdana, helvetica;color:#000000;font-size:14px;font-weight:400;">3、在軸流風機管道出口設置吸聲板,能夠使噪聲級有效地得以下降。</span><br /> <br /> <span style="line-height:2;font-style:normal;font-family:'sans serif', tahoma, verdana, helvetica;color:#000000;font-size:14px;font-weight:400;">4、設置隔聲間(室)最近為了防止或下降軸流風機噪聲的傳播,將軸流風機放置在具有吸聲功能的隔聲間內。</span><br /> <br /> <span style="line-height:2;font-style:normal;font-family:'sans serif', tahoma, verdana, helvetica;color:#000000;font-size:14px;font-weight:400;">5、對葉片進行改造處理，最常見的便是葉片穿孔辦法，這種辦法能夠下降渦流噪音，使受到的空氣阻力能很好的穿過去，通常情況下了采用工作輪葉片穿孔法，是因為葉片出風口經常出現渦流別離，采用穿孔法，能夠使部分氣流通過葉片高壓面流向葉片低壓面，能夠促進葉片別離點向流動下方移動，這樣下降了葉片出口截面的別離區，下降噪音的作用也是比較明顯。</span>
