简介

阻性(xing)消(xiao)声(sheng)(sheng)(sheng)(sheng)(sheng)器(qi)是生产的(de)(de)一种吸收(shou)型消(xiao)声(sheng)(sheng)(sheng)(sheng)(sheng)器(qi)，根(gen)据气流(liu)(liu)通道结(jie)构的(de)(de)不同，一般分为直(zhi)管(guan)式(shi)(shi)(shi)、片(pian)式(shi)(shi)(shi)、折板式(shi)(shi)(shi)、蜂窝式(shi)(shi)(shi)、声(sheng)(sheng)(sheng)(sheng)(sheng)流(liu)(liu)式(shi)(shi)(shi)、迷宫式(shi)(shi)(shi)和(he)弯(wan)头式(shi)(shi)(shi)等。阻性(xing)消(xiao)声(sheng)(sheng)(sheng)(sheng)(sheng)器(qi)是利用声(sheng)(sheng)(sheng)(sheng)(sheng)波在多孔(kong)性(xing)吸声(sheng)(sheng)(sheng)(sheng)(sheng)材料传播时，受(shou)摩擦和(he)粘(zhan)滞阻力，将声(sheng)(sheng)(sheng)(sheng)(sheng)能转化为热能耗散(san)掉，从而达到消(xiao)声(sheng)(sheng)(sheng)(sheng)(sheng)降(jiang)音的(de)(de)目的(de)(de)。它是所有(you)消(xiao)声(sheng)(sheng)(sheng)(sheng)(sheng)器(qi)中应用*为广泛的(de)(de)一类消(xiao)声(sheng)(sheng)(sheng)(sheng)(sheng)器(qi)。

抗(kang)性(xing)消(xiao)(xiao)声(sheng)(sheng)器(qi)它与(yu)阻性(xing)消(xiao)(xiao)声(sheng)(sheng)器(qi)消(xiao)(xiao)声(sheng)(sheng)降(jiang)噪(zao)原理不同，它不能(neng)直接吸收声(sheng)(sheng)能(neng)，而(er)w88win优德 消(xiao)(xiao)声(sheng)(sheng)器(qi)是利用(yong)管道上(shang)突变的界(jie)面或旁接共振(zhen)腔，使沿管道传播的某(mou)些(xie)频率(lv)声(sheng)(sheng)波，在突变的界(jie)面处发生反(fan)射、干涉等现象，从而(er)达到消(xiao)(xiao)声(sheng)(sheng)降(jiang)音的目的。分(fen)为扩张室式(shi)消(xiao)(xiao)声(sheng)(sheng)器(qi)及共振(zhen)式(shi)消(xiao)(xiao)声(sheng)(sheng)器(qi)。

因在实际噪声(sheng)控制(zhi)工程中，噪声(sheng)以宽频(pin)带居(ju)多，通常将阻性(xing)吸音降(jiang)噪声(sheng)及抗(kang)性(xing)消(xiao)声(sheng)降(jiang)音结构组合起(qi)来(lai)，以控制(zhi)高(gao)强度的宽频(pin)带噪声(sheng)。

w88win优德 消(xiao)(xiao)声(sheng)(sheng)器(qi)(qi)(qi)(qi)分(fen)为:离心w88win优德 消(xiao)(xiao)声(sheng)(sheng)器(qi)(qi)(qi)(qi)、罗茨(ci)w88win优德 消(xiao)(xiao)声(sheng)(sheng)器(qi)(qi)(qi)(qi)、鼓(gu)w88win优德 消(xiao)(xiao)声(sheng)(sheng)器(qi)(qi)(qi)(qi)、轴流w88win优德 消(xiao)(xiao)声(sheng)(sheng)器(qi)(qi)(qi)(qi)。w88win优德 消(xiao)(xiao)音器(qi)(qi)(qi)(qi)主要用于降低各种(zhong)w88win优德 风(feng)口、风(feng)道和封闭式机房(fang)进(jin)风(feng)口的(de)空气动力性噪声(sheng)(sheng) 。

分类根据w88win优德  进出口(kou)结构(gou)(gou)不(bu)同，分为(wei)(wei)(wei)圆形结构(gou)(gou)和矩形结构(gou)(gou)。w88win优德  消声器(qi)(1)圆形结构(gou)(gou)分用于w88win优德 接(jie)管口(kou)为(wei)(wei)(wei)圆形,又(you)分为(wei)(wei)(wei)A、B型(xing)(xing)两种， A型(xing)(xing)两端均为(wei)(wei)(wei)法兰盘，直接(jie)串接(jie)于管道中(即管道消声器(qi))， B型(xing)(xing)一(yi)端为(wei)(wei)(wei)法兰，另一(yi)端为(wei)(wei)(wei)直接(jie)大(da)气排(pai)空(可装防雨风(feng)(feng)帽(mao))，仅供设置(zhi)在室外管道末(mo)端和封(feng)闭式(shi)机(ji)房进风(feng)(feng)口(kou)选用。

(2)圆形(xing)结构中(zhong)的阻式消声(sheng)(sheng)片一(yi)般厚度为100 mm，150 mm，消声(sheng)(sheng)量15-30dB(A)，在风速5-12m/s的条件下(xia)，适用风量为1000-50000 m3/h。其结构中(zhong)对高(gao)频噪(zao)声(sheng)(sheng)和低(di)频噪(zao)声(sheng)(sheng)消声(sheng)(sheng)采用阻抗两(liang)种消声(sheng)(sheng)区(qu)，用以*大限度的增宽消声(sheng)(sheng)频带。
