概述;一、轴流风机消声器概述 轴流风机消声器主要用于降低轴风机噪声,一般为圆形结构,分单空腔结构和双空腔结构。ZFD单空腔型消声量为15-20dB(A),ZFS双腔型消声量为20-25dB(A),断面尺寸全部根据全国通用标准风管制作,微穿孔板采用不锈钢板或铝金板。二、轴流风机消声器规格型号型号法兰内径d(mm)外形尺寸D(mm)长度M(mm)风量(m3/h)ZFDZFSZF-100100300400350220ZF-150150350450350540ZF-200200400500400890ZF-2502504505504001600ZF-3003005406404502650ZF-3503506207205003280ZF-4004007008005004590ZF-4504507508505506050ZF-5005008209206307820ZF-5505508709706509000ZF-6006001000110080010100ZF-6506501080118085012000ZF-7007001140124095014520ZF-75075011901290100016500ZF-80080012401340110017400ZF-85085012901390120019800ZF-90090014001500130012140ZF-95095014504550135024900三、轴流风机消声器订货选型须知 (1)风机型号及使用场合; (2)风机风量及风速; (3)接管口尺寸;
