style="text-align: center;"><img width="450" height="338" title="風機消音器.jpg" style="width: 450px; height: 338px;" src="/Content/ueditor-builder/net/upload1/Other/12616/6366933724135518571724969.jpg" border="0" vspace="0" hspace="0"/></p><p style="text-align: left;"> （2）圓形結構中的阻式消聲片一般厚度為100 mm，150 mm，消聲量15-30dB(A)，在風速5-12m/s的條件下，適用風量為1000-50000 m3/h。其結構中對高頻噪聲和低頻噪聲消聲采用阻抗兩種消聲區，用以大限度的增寬消聲頻帶。<br/>因此定購風機消聲器請提供下列資料：<br/> 1）風機型號及使用場合；<br/> 2）風機風量及風速；<br/> 3）接管口尺寸.<br/></p><p> 風機消聲器注意事項：<br/> 1、風機消音器的氣體含塵量一般應低于150mg/m3。如在高粉塵場合下使用，應先經除塵濾清。<br/> 2、露天使用加防雨棚，風機消音器不允許含水霧太大、油霧或腐蝕性氣體通過，氣體溫度≤150℃。<br/> 3、如果空氣含塵量影響吸音效果，可以半年清潔一次，清刷消音單元表面上的灰塵。<br/> 4、定期清理防雨棚立柱四周絲網上的雜物。<br/> 風機是一種通用機械設備，其使用范圍很廣，電力、礦山、機械、冶金、化工等各行業的生產均離不開風機。</p><p><br/></p><p>
