注意消聲器的凈通道截面積，風管和消聲器連接時，必要時（風速有限制時）需作放大處理。 · 消聲器等消聲設備安裝，須有獨立的承重吊桿或底座；與聲源設備須通過軟接頭連接。 · 當兩個消聲彎頭串聯使用時，兩個彎頭的連接間距應大于彎頭截面對角線長度的2.5倍。 · 對于高溫、高濕、有油霧、水氣的環境系統一般選用微孔結構消聲設備，對于有潔凈要求的諸如手術室、錄音室、潔凈廠房等環境系統，應采用微孔結構消聲設備。 · 相鄰用房管路串通時，注意室內噪聲通過管路相互影響，必要時風口作消聲處理</p><p><br/></p><p>本文由連云港晨源環?？萍加邢薰菊戆l布</p></div> <div class="fanye"> <span class="fl">上一條: <a
