安装风机消声器后能降多少分贝?

     连云港市J9九游会AG电力(li)辅机(ji)有限公(gong)司生产的(de)风机(ji)消声器(qi)(qi)系列产品为阻抗(kang)声流(liu)型(xing)消声器(qi)(qi)。安装我公(gong)司的(de)风机(ji)消声器(qi)(qi)后能降(jiang)多少分贝呢?

风机消声器

     本厂根据对发电厂各(ge)类风(feng)机运行(xing)现场噪(zao)(zao)声(sheng)(sheng)(sheng)源进行(xing)实际测试(shi)所取得的(de)濒特性资料来确定在(zai)哪些(xie)频(pin)谱(pu)范围内需(xu)要多大(da)(da)消(xiao)声(sheng)(sheng)(sheng)量作为(wei)设计吸(xi)声(sheng)(sheng)(sheng)片结(jie)(jie)构及流体通(tong)道的(de)主要依据,同(tong)时(shi)采(cai)用(yong)了(le)具有(you)较大(da)(da)吸(xi)声(sheng)(sheng)(sheng)材料饰面(mian)的(de)狭矩形通(tong)道,以(yi)增强吸(xi)收效果。J9九游会AG 知道,风(feng)机的(de)噪(zao)(zao)声(sheng)(sheng)(sheng)源在(zai)大(da)(da)噪(zao)(zao)声(sheng)(sheng)(sheng)级时(shi),其频(pin)谱(pu)值往(wang)(wang)往(wang)(wang)不止一(yi)种,而对不同(tong)频(pin)谱(pu)带(dai),对其消(xiao)声(sheng)(sheng)(sheng)量要求也不相同(tong)。       为(wei)此本风(feng)机消(xiao)声(sheng)(sheng)(sheng)器采(cai)用(yong)了(le)对高(gao)(gao)、中频(pin)噪(zao)(zao)声(sheng)(sheng)(sheng)起(qi)消(xiao)声(sheng)(sheng)(sheng)作用(yong)的(de)阻式结(jie)(jie)构及对中、低频(pin)噪(zao)(zao)声(sheng)(sheng)(sheng)起(qi)消(xiao)声(sheng)(sheng)(sheng)作用(yong)的(de)抗式结(jie)(jie)构,同(tong)时(shi)在(zai)阻式通(tong)道中采(cai)用(yong)了(le)高(gao)(gao)频(pin)及低频(pin)两种消(xiao)声(sheng)(sheng)(sheng)区,用(yong)以(yi)大(da)(da)限度的(de)增宽消(xiao)声(sheng)(sheng)(sheng)频(pin)带(dai),以(yi)实现良好(hao)的(de)消(xiao)声(sheng)(sheng)(sheng)效果。本产品当用(yong)户按要求安装后(hou),其极限噪(zao)(zao)声(sheng)(sheng)(sheng)级将(jiang)不超过85~90分贝。
