导读：罗茨风机消声器主要作用，罗茨风机消声器又称罗茨风机消声器可用于降低各类风机的进/排气噪声，也可以用于对排气管道及其它高压风机的降噪。

罗茨风机消声器又称罗茨风机消声器可用于降低各类风机的进/排气噪声，也可以用于对排气管道及其它高压风机的降噪。

罗茨风机消声器/消声器主要用于各种系列的高压离心通风机，用于降低进，出风口等空气动力-噪声。本产-当用户按要求安装后，其-限噪声-将不-过85～90分贝。

罗茨风机消声器/消声器是根据阻声片消声原理所研制，该型消声器声学-能-良，空气动力-能良-；结-合理，便于安装，是-种大风量阻-蜂窝式消声器，抗--采用了-室抗-胶直管通道及十字形吸声片形式，从而保-了在较宽频带范围内具有足够的消声量。消声器结-由许-平行的单元消声管排列组成，消声管之间填充-孔吸声材料，为减少气流-发壳壁振动而产生辐射声，在外壳上设置了加强筋。风机消声器、离心风机消声器以及鼓引风机消声器的形式均采用对-、高频宽带--有较--果的阻-吸-降噪原理，对低、-频和脉动--时有良--果的抗-消声降-原理以及微穿孔消声器和阻抗复合式消声器。

风机消声器分为：离心风机消声器、罗茨风机消声器、鼓风机消声器、轴流风机消声器。风机消声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-噪声。 1、根据风机进出口结-不同，分为圆形结-和矩形结-。 1）：圆形结-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-(即管道消声器)，B型-端为法兰，另-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--的阻式消声片-般厚度为100mm，150mm，消声量15-30dB(A)，在风速5-12m/s的条件下，适用风量为1000-50000m3/h。其结--对高频噪声和低频噪声消声采用阻抗两种消声区，用以-大限度的增宽消声频带。
