產品(pin)概覽:

吸收型：壓縮空(kong)氣通過多(duo)孔的吸聲材料(liao)減少(shao)排(pai)氣噪聲。吸聲材料(liao)大多(duo)使用聚氯乙烯纖(xian)維、玻(bo)璃纖(xian)維、燒結銅珠等(deng)；

2）膨脹(zhang)干涉(she)型：直(zhi)徑比排(pai)氣孔大，主要用于消(xiao)除中、低頻噪(zao)聲。

其吸(xi)(xi)聲(sheng)(sheng)(sheng)(sheng)系數(shu)高(gao)(gao)，吸(xi)(xi)收頻(pin)(pin)帶(dai)寬，壓力損(sun)失小，氣(qi)流(liu)再生噪(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)低(di)，且易于(yu)(yu)(yu)控(kong)制。為獲得寬頻(pin)(pin)帶(dai)高(gao)(gao)吸(xi)(xi)收效果，一(yi)般(ban)用三級微(wei)(wei)(wei)(wei)穿孔(kong)板(ban)(ban)結構(gou)(gou)。微(wei)(wei)(wei)(wei)穿孔(kong)板(ban)(ban)與(yu)外殼體(ti)之(zhi)間以(yi)及微(wei)(wei)(wei)(wei)穿板(ban)(ban)之(zhi)間的(de)(de)空腔(qiang)尺寸大小按需要吸(xi)(xi)收的(de)(de)頻(pin)(pin)帶(dai)不同而(er)異(yi)，低(di)頻(pin)(pin)腔(qiang)大(150~200mm),中(zhong)頻(pin)(pin)小些(80~120mm)，高(gao)(gao)頻(pin)(pin)更小些(30~50mm)，雙層結構(gou)(gou)的(de)(de)前腔(qiang)深度(du)一(yi)般(ban)應小于(yu)(yu)(yu)后(hou)腔(qiang)，前后(hou)腔(qiang)深度(du)之(zhi)比(bi)不大于(yu)(yu)(yu)1:3，前部接近氣(qi)流(liu)的(de)(de)一(yi)層微(wei)(wei)(wei)(wei)穿孔(kong)板(ban)(ban)穿孔(kong)率(lv)應高(gao)(gao)于(yu)(yu)(yu)后(hou)層，為減小軸向聲(sheng)(sheng)(sheng)(sheng)傳播的(de)(de)影響(xiang)，可在(zai)微(wei)(wei)(wei)(wei)穿孔(kong)板(ban)(ban)消(xiao)聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi)的(de)(de)空腔(qiang)內每隔500mm左右(you)加一(yi)塊橫(heng)向隔板(ban)(ban)。試驗證明，微(wei)(wei)(wei)(wei)穿孔(kong)板(ban)(ban)消(xiao)聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi)不論是(shi)低(di)頻(pin)(pin)、中(zhong)頻(pin)(pin)、高(gao)(gao)頻(pin)(pin)消(xiao)聲(sheng)(sheng)(sheng)(sheng)性能實測(ce)值比(bi)理論估算值要好。且消(xiao)聲(sheng)(sheng)(sheng)(sheng)量(liang)與(yu)流(liu)速(su)有關，與(yu)消(xiao)聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi)溫升無(wu)(wu)關，當流(liu)速(su)達(da)到70米(mi)/秒時，一(yi)般(ban)其它型(xing)式消(xiao)聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi)已無(wu)(wu)法解決噪(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)問題，而(er)微(wei)(wei)(wei)(wei)孔(kong)型(xing)消(xiao)聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi)可承(cheng)受(shou)70m/s氣(qi)流(liu)速(su)度(du)的(de)(de)沖擊(ji)，仍有15dBA以(yi)上的(de)(de)消(xiao)聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi)。這也(ye)是(shi)微(wei)(wei)(wei)(wei)孔(kong)消(xiao)聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi)優(you)于(yu)(yu)(yu)一(yi)般(ban)消(xiao)聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi)一(yi)個重要特(te)點。
