4.2.3ZWB型消声弯管是使风管绕短边B拐弯90,并有一定消 声作用的弯管,其拐弯半径为风管内壁长边A。吸声材料厚度分50 和100mm
选用消声器(弯管)时,应同时满足以下条件: 5.1消声器的各频率消声量都应大于或等于使用要求的衰减量。如 不满足时,可用两种办法解决:,选用二只或数只(二种或数种)消声 器(弯管)串联使用,使它们的消声量叠加值略高于所要求的消声量(约 1.25倍),应注意此时总阻力也为叠加值;b.如选用ZP100型消声器时 最好按阻性消声器的消声量和其有效长度成正比”的规律加长消声器 的有效长度,此时不仅能满足消声要求,而且由于消声器的局部阻力没 有增加,摩操阻力又增加极小,因此总阻力基本不变,仍可按原值考虑, 5.2与消声器(弯管)连接的风管内的风速不应超过下表规定的数
此时消声器的气流再生噪声影响极小,可直接按风管尺寸选用消 声器,消声器实际消声量即为额定值。 6.4对于录音室,剧场等降噪要求高的工程,消声器不宜集中安装 在一起,应在主风管分支管、风口前等处分别设置,并逐步降低风管内
气流速度。 7.施工安装 7.1消声器(弯管)前应安装柔性接头,且消声器(弯管)后的风管不 应再穿越高噪声区,如必须穿越时,应对风管和消声器作隔声处理。 乙.2消声器(驾管)两端应设置独立的支架或吊架。如安装于室外屋 面,墙面时,还需采取防雨措施。 7.3在弯头、三通及风门之后安装消声器(弯管)时,应在消声器(弯 管)之前配置一段长度不小于50cm的过渡管,二只或二只以上消声器 弯管)事联安装时,过渡管长度也应不小于50cm。 7.4在保温风管或输送气体温度高于80℃的风管上安装消声器(有 管)时,消声器(弯管)的吸声有效段外壁不再需要绝热保温。 8.本图集由上海大观园通风消声设备有限公司协助编制, 9、产品加工制作图由中国建筑标准设计研究所有偿提供
