對于常州商用廚房設備噪音大的難點，很多朋友不清楚該如何解決，今天常州不銹鋼廚房設備廠(chang)家(jia)就來為大(da)家(jia)詳(xiang)解(jie)一(yi)下降低廚(chu)房設備源噪聲的方法。

1.合理選擇自然通(tong)(tong)風(feng)機(ji)(ji)(ji)械設備(bei)(bei)的(de)(de)型(xing)號(hao)規格，在(zai)(zai)噪聲(sheng)控制要求高的(de)(de)場(chang)地，應拿取低噪聲(sheng)自然通(tong)(tong)風(feng)機(ji)(ji)(ji)械設備(bei)(bei)。不一樣規格型(xing)號(hao)的(de)(de)自然通(tong)(tong)風(feng)機(ji)(ji)(ji)械設備(bei)(bei)在(zai)(zai)想(xiang)要的(de)(de)風(feng)量、標準氣壓下、翼型(xing)葉片的(de)(de)旋(xuan)蒸自然通(tong)(tong)風(feng)機(ji)(ji)(ji)械設備(bei)(bei)噪聲(sheng)小(xiao)，前向樣式(shi)葉片的(de)(de)旋(xuan)蒸自然通(tong)(tong)風(feng)機(ji)(ji)(ji)械設備(bei)(bei)噪聲(sheng)大。

2.在必要(yao)條件下適(shi)當降(jiang)低(di)自然通風(feng)(feng)機(ji)械設備的傳動(dong)比(bi)，自然通風(feng)(feng)機(ji)械設備的旋轉(zhuan)噪(zao)聲(sheng)與風(feng)(feng)機(ji)葉(xie)輪圓(yuan)上(shang)速度(du)10三(san)次方(fang)(fang)成占有(you)率，渦流噪(zao)聲(sheng)與風(feng)(feng)機(ji)葉(xie)輪圓(yuan)上(shang)速度(du)6三(san)次方(fang)(fang)(或5三(san)次方(fang)(fang))成占有(you)率。故(gu)降(jiang)低(di)傳動(dong)比(bi)可降(jiang)低(di)噪(zao)聲(sheng)。

3.自(zi)然(ran)通風機械設備(bei)進、入(ru)口(kou)處的噪聲級是(shi)自(zi)然(ran)通風理(li)、標(biao)準氣壓(ya)曾加而擴張。因此，方案設計自(zi)然(ran)通風系(xi)統(tong)時，應盡量減(jian)少系(xi)統(tong)的壓(ya)力危害。當自(zi)然(ran)通風系(xi)統(tong)的總產值和壓(ya)力危害挺大時，可將(jiang)其(qi)分(fen)為小(xiao)系(xi)統(tong)。

4.自(zi)(zi)然(ran)(ran)通(tong)(tong)風(feng)(feng)機(ji)械(xie)(xie)設(she)備(bei)(bei)的工(gong)(gong)作中位(wei)置(zhi)應(ying)接(jie)近高效率(lv)高些(xie)，統一(yi)規格(ge)型號(hao)的自(zi)(zi)然(ran)(ran)通(tong)(tong)風(feng)(feng)機(ji)械(xie)(xie)設(she)備(bei)(bei)效率(lv)高越高，噪(zao)聲(sheng)越小。為使(shi)自(zi)(zi)然(ran)(ran)通(tong)(tong)風(feng)(feng)機(ji)械(xie)(xie)設(she)備(bei)(bei)的運行工(gong)(gong)作中情(qing)況保(bao)持在自(zi)(zi)然(ran)(ran)通(tong)(tong)風(feng)(feng)機(ji)械(xie)(xie)設(she)備(bei)(bei)的高效率(lv)區，應(ying)盡(jin)量避免用截止閥進行工(gong)(gong)作中情(qing)況調(diao)節。如(ru)不可(ke)或缺在自(zi)(zi)然(ran)(ran)通(tong)(tong)風(feng)(feng)機(ji)械(xie)(xie)設(she)備(bei)(bei)壓進去端(duan)設(she)截止閥時，其設(she)置(zhi)的位(wei)置(zhi)是距(ju)自(zi)(zi)然(ran)(ran)通(tong)(tong)風(feng)(feng)機(ji)械(xie)(xie)設(she)備(bei)(bei)入口(kou)處(chu)1m處(chu)。它(ta)能使(shi)2000Hz以下(xia)的噪(zao)聲(sheng)降低。在自(zi)(zi)然(ran)(ran)通(tong)(tong)風(feng)(feng)機(ji)械(xie)(xie)設(she)備(bei)(bei)進口(kou)處(chu)氣流應(ying)保(bao)持平均值(zhi)。

5.留意自然通(tong)風機械(xie)設備與電念頭(tou)的傳(chuan)(chuan)動裝置方式。采用(yong)直聯傳(chuan)(chuan)動裝置的自然通(tong)風機械(xie)設備噪聲小，用(yong)聯軸器的次之(zhi)，用(yong)沒(mei)有接口處的三角同步帶傳(chuan)(chuan)動的稍弱。
