消聲器動態評價實驗室



本實驗室依據GB/T25516-2010(ISO 7235:2003,IDT)建設,用于測量通風類消聲器、彎頭、T型連接管和風道末端等設備的插入損失、全壓損失和氣流噪聲。

消聲器動態評價實驗室分為地下風機和和地上測試管道及接收室組成,地下風機前后設置有消聲器,以降低風機運行時產生的設備噪聲。

 

    The laboratory was built according to GB/T25516-2010(ISO 7235:2003,IDT), aiming at measuring the insertion loss, total pressure loss and airflow noise of ventilation muffler, elbow, T-connection tube and equipments at the terminal end of air duct.

    The muffler dynamic evaluation laboratory is composed of the underground fan, the aboveground test pipe and the sound reception room. The muffler is provided before and after the underground fan to reduce its noise while running.
