對于徐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,今天徐州不銹鋼廚房設備廠(chang)家就來為大家詳(xiang)解一下降低廚房(fang)設備源噪(zao)聲的方法。
1.合理選(xuan)擇自(zi)然(ran)(ran)通(tong)風(feng)(feng)(feng)機(ji)械(xie)設(she)備的(de)型號規格,在(zai)噪聲(sheng)控制要(yao)求(qiu)高的(de)場(chang)地,應(ying)拿取(qu)低噪聲(sheng)自(zi)然(ran)(ran)通(tong)風(feng)(feng)(feng)機(ji)械(xie)設(she)備。不一(yi)樣規格型號的(de)自(zi)然(ran)(ran)通(tong)風(feng)(feng)(feng)機(ji)械(xie)設(she)備在(zai)想要(yao)的(de)風(feng)(feng)(feng)量、標準氣(qi)壓(ya)下、翼型葉(xie)(xie)片的(de)旋蒸自(zi)然(ran)(ran)通(tong)風(feng)(feng)(feng)機(ji)械(xie)設(she)備噪聲(sheng)小,前(qian)向樣式(shi)葉(xie)(xie)片的(de)旋蒸自(zi)然(ran)(ran)通(tong)風(feng)(feng)(feng)機(ji)械(xie)設(she)備噪聲(sheng)大。
2.在必要條件下適(shi)當降低(di)自然通(tong)風機(ji)(ji)械設(she)備的(de)(de)傳(chuan)動(dong)比(bi),自然通(tong)風機(ji)(ji)械設(she)備的(de)(de)旋轉噪聲(sheng)(sheng)與風機(ji)(ji)葉(xie)輪(lun)圓上(shang)速度(du)(du)10三次(ci)方(fang)成占有(you)率,渦(wo)流(liu)噪聲(sheng)(sheng)與風機(ji)(ji)葉(xie)輪(lun)圓上(shang)速度(du)(du)6三次(ci)方(fang)(或5三次(ci)方(fang))成占有(you)率。故(gu)降低(di)傳(chuan)動(dong)比(bi)可(ke)降低(di)噪聲(sheng)(sheng)。
3.自然通(tong)風機械設備進、入口處的(de)噪聲(sheng)級(ji)是自然通(tong)風理、標準氣壓曾(ceng)加而擴張。因此,方(fang)案設計(ji)自然通(tong)風系(xi)統時,應盡量減少系(xi)統的(de)壓力危(wei)害。當(dang)自然通(tong)風系(xi)統的(de)總產值和壓力危(wei)害挺大時,可(ke)將其分為小系(xi)統。
4.自(zi)(zi)(zi)然(ran)(ran)通(tong)(tong)(tong)風(feng)機(ji)(ji)(ji)械(xie)設(she)備(bei)(bei)的(de)(de)工(gong)作(zuo)中(zhong)位置(zhi)應(ying)(ying)接近高(gao)(gao)效(xiao)率高(gao)(gao)些,統一(yi)規(gui)格型號的(de)(de)自(zi)(zi)(zi)然(ran)(ran)通(tong)(tong)(tong)風(feng)機(ji)(ji)(ji)械(xie)設(she)備(bei)(bei)效(xiao)率高(gao)(gao)越(yue)高(gao)(gao),噪聲越(yue)小。為使自(zi)(zi)(zi)然(ran)(ran)通(tong)(tong)(tong)風(feng)機(ji)(ji)(ji)械(xie)設(she)備(bei)(bei)的(de)(de)運行工(gong)作(zuo)中(zhong)情(qing)況保持(chi)(chi)在自(zi)(zi)(zi)然(ran)(ran)通(tong)(tong)(tong)風(feng)機(ji)(ji)(ji)械(xie)設(she)備(bei)(bei)的(de)(de)高(gao)(gao)效(xiao)率區,應(ying)(ying)盡量避免(mian)用截止閥進(jin)行工(gong)作(zuo)中(zhong)情(qing)況調節。如不可或缺在自(zi)(zi)(zi)然(ran)(ran)通(tong)(tong)(tong)風(feng)機(ji)(ji)(ji)械(xie)設(she)備(bei)(bei)壓(ya)進(jin)去端設(she)截止閥時,其設(she)置(zhi)的(de)(de)位置(zhi)是距自(zi)(zi)(zi)然(ran)(ran)通(tong)(tong)(tong)風(feng)機(ji)(ji)(ji)械(xie)設(she)備(bei)(bei)入口(kou)處1m處。它能(neng)使2000Hz以下的(de)(de)噪聲降(jiang)低(di)。在自(zi)(zi)(zi)然(ran)(ran)通(tong)(tong)(tong)風(feng)機(ji)(ji)(ji)械(xie)設(she)備(bei)(bei)進(jin)口(kou)處氣流應(ying)(ying)保持(chi)(chi)平均值。
5.留(liu)意自然(ran)通風(feng)機械(xie)設備(bei)與電(dian)念頭的(de)傳(chuan)(chuan)動(dong)裝置方式。采用(yong)直聯傳(chuan)(chuan)動(dong)裝置的(de)自然(ran)通風(feng)機械(xie)設備(bei)噪聲(sheng)小,用(yong)聯軸器的(de)次之,用(yong)沒有接口處的(de)三角同步帶傳(chuan)(chuan)動(dong)的(de)稍弱。
