ZKS型折板式消聲器用途

ZKS折(zhe)(zhe)板(ban)(ban)式(shi)消(xiao)聲(sheng)(sheng)器(qi)是經(jing)改良的(de)(de)(de)一(yi)種片(pian)式(shi)阻(zu)(zu)性消(xiao)聲(sheng)(sheng)器(qi)，吸(xi)音(yin)(yin)片(pian)呈折(zhe)(zhe)板(ban)(ban)狀，增(zeng)(zeng)加了(le)(le)(le)聲(sheng)(sheng)波(bo)(bo)(bo)的(de)(de)(de)反(fan)射(she)(she)次(ci)數，使(shi)(shi)得消(xiao)聲(sheng)(sheng)性能(neng)(neng)提高，該消(xiao)聲(sheng)(sheng)器(qi)采用(yong)玻璃棉作吸(xi)音(yin)(yin)材(cai)料，鍍鋅穿孔(kong)板(ban)(ban)和超細玻璃棉布為護板(ban)(ban)，管(guan)道(dao)有效通道(dao)比較大，壓力損失小，是一(yi)種性能(neng)(neng)優良的(de)(de)(de)消(xiao)聲(sheng)(sheng)器(qi)。主要也是利(li)用(yong)多孔(kong)吸(xi)聲(sheng)(sheng)材(cai)料來(lai)降低噪聲(sheng)(sheng)的(de)(de)(de)。除了(le)(le)(le)把吸(xi)聲(sheng)(sheng)材(cai)料固(gu)定(ding)在(zai)(zai)氣流(liu)通道(dao)的(de)(de)(de)內壁上意外，還要將(jiang)阻(zu)(zu)性折(zhe)(zhe)板(ban)(ban)式(shi)吸(xi)聲(sheng)(sheng)原件按(an)一(yi)定(ding)的(de)(de)(de)方式(shi)均勻的(de)(de)(de)排(pai)列(lie)在(zai)(zai)通道(dao)內，就構成了(le)(le)(le)阻(zu)(zu)性折(zhe)(zhe)板(ban)(ban)式(shi)消(xiao)音(yin)(yin)器(qi)。為減(jian)小消(xiao)聲(sheng)(sheng)器(qi)的(de)(de)(de)阻(zu)(zu)力，折(zhe)(zhe)板(ban)(ban)消(xiao)聲(sheng)(sheng)片(pian)迎(ying)氣流(liu)端部可設導流(liu)頭。當聲(sheng)(sheng)波(bo)(bo)(bo)進入(ru)阻(zu)(zu)性消(xiao)音(yin)(yin)器(qi)時，一(yi)部分聲(sheng)(sheng)能(neng)(neng)在(zai)(zai)多孔(kong)材(cai)料的(de)(de)(de)孔(kong)隙中摩擦而(er)轉化成熱能(neng)(neng)耗(hao)散掉，使(shi)(shi)通過消(xiao)音(yin)(yin)器(qi)的(de)(de)(de)聲(sheng)(sheng)波(bo)(bo)(bo)減(jian)弱。由于折(zhe)(zhe)板(ban)(ban)相對片(pian)式(shi)的(de)(de)(de)元(yuan)件的(de)(de)(de)通道(dao)略(lve)有加長，且(qie)聲(sheng)(sheng)波(bo)(bo)(bo)在(zai)(zai)折(zhe)(zhe)板(ban)(ban)通道(dao)內反(fan)復(fu)多次(ci)折(zhe)(zhe)射(she)(she)碰撞，增(zeng)(zeng)加了(le)(le)(le)聲(sheng)(sheng)波(bo)(bo)(bo)與吸(xi)聲(sheng)(sheng)元(yuan)件接觸的(de)(de)(de)時間，所以消(xiao)聲(sheng)(sheng)性能(neng)(neng)有所增(zeng)(zeng)加。但反(fan)復(fu)折(zhe)(zhe)射(she)(she)碰撞也加大了(le)(le)(le)阻(zu)(zu)力損失。

ZKS型折板(ban)式消聲器性(xing)能特點

1、ZKS型折(zhe)板(ban)式(shi)(shi)消(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)器(qi)消(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)性(xing)能以中高頻為(wei)主，消(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)量及壓(ya)力損(sun)失大(da)于(yu)片式(shi)(shi)消(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)器(qi)，長度L=900mm，一般以1-2節為(wei)宜。在ZKS型折(zhe)板(ban)式(shi)(shi)消(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)器(qi)外(wai)殼加隔(ge)聲(sheng)(sheng)(sheng)處理后，即為(wei)ZKSA型，其(qi)消(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)性(xing)能與(yu)壓(ya)力損(sun)失和ZKS型折(zhe)板(ban)式(shi)(shi)消(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)器(qi)相同(tong)。消(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)量及壓(ya)力損(sun)失大(da)于(yu)（22～25dB(A)/m，40Pa/m）片式(shi)(shi)消(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)器(qi)。

2、當消聲器設在機(ji)房或噪聲較高的房間時宜采用ZKSA型折(zhe)板式(shi)消聲器。

3、ZKS型(xing)消聲(sheng)器不宜(yi)配(pei)置在機房(fang)內(nei)或其他噪聲(sheng)較高的(de)房(fang)間內(nei)，以防(fang)止聲(sheng)短路。
