风机消声器

    风机消声器分为:离心风机消音器、罗茨风机消声器、鼓风机消声器、轴流风机消声器。风机消音器主要用于降低各种风机风口、风道和封闭式机房进风口的空气动力性噪声 。

风机消声器,排气管道消声器以及鼓引风机消声器的形式均采用对中、高频宽带特性有较好效果的阻性吸音降噪原理,对低、中频和脉动特性时有良好效果的抗性消声降音原理以及微穿孔消声器和阻抗复合式消声器。   

    Fan muffler is divided into: centrifugal fan muffler, Roots blower muffler, blower muffler, axial fan muffler. Fan muffler is mainly used to reduce all kinds of fan tuyere, air duct and enclosed room air inlet aerodynamic noise.
    Fan  muffler, exhaust pipe muffler and drum blower muffler are used in the  form of medium and high frequency broadband characteristics have a  better effect of the resistive sound-absorbing noise reduction  principle, low, intermediate frequency and pulse characteristics have a  good effect when the anti-consumer Sound reduction principle and micro-perforated muffler and impedance composite muffler.

    根据风机进出口结构不同,分为圆形结构和矩形结构。

   (1)圆形结构分用于风机接管口为圆形,又分为A、B型两种, A型两端均为法兰盘,直接串接于管道中(即管道消声器), B型一端为法兰,另一端为直接大气排空(可装防雨风帽),仅供设置在室外管道末端和封闭式机房进风口选用。

   (2)圆形结构中的阻式消声片一般厚度为100 mm,150 mm,消声量15-30dB(A),在风速5-12m/s的条件下,适用风量为1000-50000 m3/h。其结构中对高频噪声和低频噪声消声采用阻抗两种消声区,用以最大限度的增宽消声频带。

    Fan import and export according to different structures, divided into circular structure and rectangular structure.

    (1) The circular structure is divided into circular nozzle for the fan, is divided into two types of A, B, A-type flange at both ends, directly connected in the pipeline (that is, pipe muffler), B One end of the flange, the other end of the direct air exhaust (which can be mounted rain hood), only set at the end of the outdoor pipe and closed room air inlet selection.

    (2) The resistive mufflers in the circular structure are generally 100 mm in thickness and 150 mm in thickness, 15-30 dB (A) in muffler volume. For a wind speed of 5-12 m / s, the applicable air volume is 1000-50000 m3 / h The structure of the high-frequency noise and low-frequency noise muffler impedance muffler with two areas, to maximize the widening of the anechoic band.
