不銹鋼專業消聲器風管的空氣流動性好,有效通流面積大,由于強度大,因此風管振動引起的低頻噪聲更小,空消聲器定制氣流動性(xing)能好,系(xi)統(tong)壓降小,日常運行系(xi)統(tong)耗電量少。目前還可以(yi)采用扁橢(tuo)圓(yuan)形風管來降低風管的占用空間高度,由(you)于風管的兩邊是(shi)圓(yuan)形,所以(yi)氣流穩(wen)定,風管的剛性(xing)好,外露(lu)安裝美觀性(xing)好,是(shi)比較理想的風管系(xi)列(lie)。
送冷風和熱風常見的是消聲器定制中央空調的管道,這種管道需要加保溫材料。也可內貼保溫材料,使風道具有螺旋形的漂專業消聲器亮外觀,可免(mian)吊頂,從而降低了工(gong)程(cheng)造價(jia)(jia)。送(song)新(xin)風和(he)排氣(qi),將有(you)(you)害氣(qi)體(ti)排出室外,把室外新(xin)鮮空氣(qi)送(song)至室內(nei)。一(yi)般(ban)而言,通風系統(tong)的流量都很大,因此要求使用阻力較小的空氣(qi)輸送(song)管道,以節(jie)省(sheng)造價(jia)(jia)和(he)運(yun)行(xing)費(fei)用——就適用。一(yi)般(ban)情(qing)況(kuang)下使用鍍鋅鐵(tie)管,有(you)(you)腐蝕性及特別(bie)潮濕的場所(suo)使用不銹鋼管。
重要的鋅專業消聲器的化合物是氧化鋅,俗名叫“鋅白”,是著名的白色顏料,用來制造白色油漆等。在室溫下氧化消聲器定制鋅是白色(se)的,受熱后卻會變成黃色(se),而再(zai)冷(leng)卻時,又(you)重新變成白色(se)。現在(zai),人們(men)利用(yong)它的這個特(te)點,制成“變色(se)溫度計”——用(yong)它顏色(se)的變化(hua)來(lai)測(ce)量溫度。
