一、风机消声器 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。根据风机进出口结构不同,分为GFY型圆形结构和GFP型矩形结构。(1):GFY型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。GFY型圆形结构中的阻式消声片一般厚度为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。序号法兰内径D(mm)外形尺寸(mm)有效长度L(mm)风量(m/s)外径D安装长度L1A型B型A型B型1230450150015001100135020002340600160016001200145050003420730175017501300160080004500790180018001350165012000558090019001930145017801600066509501950203015001880200007700100021002230165020802500087801100215023001680215030000984011802200238017202200350001090013302300245017502250400001110001420235025501800235050000(2):GFP型矩形结构(也称片式结构),既消声器接口与风机接口为距形,消声器中的阻式消声片一般厚度为100mm和200mm。GFP-100型四周吸声层和中间吸声片厚度为100mm,GFP-200型四周吸声层厚度为200mm,消声量15-30dB(A),在风速5-15m/s的条件下,适用风量为1000-150000m3/h。压力损失25~255Pa。GFP-100型片式消声器系列规格序号法兰内径A B(mm)外形尺寸(mm)Ao Bo Lo有效长度lo(mm)适用风量(m3/h)v=5m/s~v=10m/s1200 200800 400 130010001800~36002320 320800 520 130010002880~57603400 3201030 520 145010003620~72404630 5001030 700 145010005670~113405800 3201200 520 145010004600~92006800 5001200 700 145010007200~144007800 6301400 830 160010009070~1814081000 3201400 520 160010005760~1152091000 5001400 700 160010009000~18000101000 6301400 830 1600100011340~22680111000 8001650 1000 1600100014400~28800121250 3201650 520 160010007200~14400131250 5001650 700 1600100011250~22500141250 6301650 830 1600100014175~28350151250 8001650 1000 1600100018000~36000161250 10001650 1200 1600100022500~45000171600 3202200 520 160010009216~18432181600 5002200 700 1600100014400~28800191600 6302200 830 1600100018140~36280201600 8002200 1000 1600100023040~46080211600 10002200 1200 1600100028800~57600221600 12502200 1450 1600100036000~72000232000 5002440 700 1600100018000~36000242000 6302440 830 1600100022680~45360252000 8002440 1000 1600100028800~57600262000 10002440 1200 1600100036000~72000272000 12502440 1450 1600100045000~90000282000 16002440 1800 1600100057600~115200
