高压离心通风机消声器一、结构型式本系列消声器为一种阻抗复合式消声器，其阻性段采用列管吸声通道，抗性段采用了多室抗性腔直管通道及十字形吸声片形式，从而保证了在较宽频带范围内具有足够的消声量。二、适用范围主要用于各种系列（8-18型、9-27型）的高压离心通风机，用于降低进、出风口等空气动力性噪声。JD-QX型两端均为法兰联接可串接于管道中。JD-QH型一端为防雨帽，仅供设置在室外管道末端和封闭式机房进风口选用。三、规格、性能、外形尺寸适用流量(m3/h)外形尺寸外径D法兰尺寸(mm)气流度速(m/s)阻力损失(Pa)外径D有效长度安装长度L内径D1螺孔中心圆直径D2外径D3联接孔QXQH孔径d孔数nJD-QX-1JD-QH-1220045013001550165023031835012613.4170JD-QX-2JD-QH-2500060013001550165034042645014813.5215JD-QX-3JD-QH-38000730130016001700420506540141216235JD-QX-4JD-QH-412000790140018001800500606640141217260JD-QX-5JD-QH-515000900154018902020580686720141217260JD-QX-6JD-QH-620000950164019902140650806790141217260JD-QX-7JD-QH-7250001000169020402240700816840141218300JD-QX-8JD-QH-8300001100175021502400780886920141617.5280JD-QX-9JD-QH-9350001180180022002500840945980141617.6280JD-QX-10JD-QH-1040000133018802250260090010061040142417.5280JD-QX-11JD-QH-11500001420199022502650100011061140142417.7280JD-QX-12JD-QH-12800001780290032003600130014201480303016.7300JD-QX型高压离心通风机消声器JD-QH型高压离心通风机消声器)
