運行噪(zao)(zao)音(yin)主要源于(yu)機械(xie)振(zhen)(zhen)動(dong)(dong)(dong)、流(liu)體擾動(dong)(dong)(dong)和電(dian)(dian)氣部件(jian)。機械(xie)振(zhen)(zhen)動(dong)(dong)(dong)是最主要來(lai)源，攪(jiao)拌(ban)器與電(dian)(dian)機的不(bu)平衡、軸承磨損、傳(chuan)動(dong)(dong)(dong)部件(jian)松動(dong)(dong)(dong)等都會引發振(zhen)(zhen)動(dong)(dong)(dong)噪(zao)(zao)聲。流(liu)體擾動(dong)(dong)(dong)噪(zao)(zao)音(yin)產(chan)生于(yu)物(wu)(wu)料(liao)攪(jiao)拌(ban)時(shi)的湍流(liu)以及導熱油(you)流(liu)動(dong)(dong)(dong)，特別是高粘度物(wu)(wu)料(liao)攪(jiao)拌(ban)或(huo)夾套(tao)油(you)循環(huan)不(bu)暢時(shi)更為(wei)明(ming)顯。電(dian)(dian)氣部件(jian)如接觸器吸(xi)合、電(dian)(dian)機電(dian)(dian)磁振(zhen)(zhen)動(dong)(dong)(dong)也會產(chan)生噪(zao)(zao)音(yin)。降噪(zao)(zao)措施包括(kuo)：對攪(jiao)拌(ban)系(xi)統進行動(dong)(dong)(dong)平衡校準，更換(huan)磨損的軸承和傳(chuan)動(dong)(dong)(dong)皮帶，加固設備底座并安(an)裝減震墊，阻斷振(zhen)(zhen)動(dong)(dong)(dong)傳(chuan)遞；優(you)化攪(jiao)拌(ban)槳葉(xie)形狀和安(an)裝角度，降低(di)流(liu)體阻力；在反應(ying)鍋外部加裝隔(ge)音(yin)罩，采(cai)用吸(xi)音(yin)材(cai)料(liao)（如玻璃棉、聚氨酯泡沫）包裹，隔(ge)絕噪(zao)(zao)音(yin)傳(chuan)播(bo)；選用低(di)噪(zao)(zao)音(yin)電(dian)(dian)機和電(dian)(dian)氣元件(jian)，并對控制柜進行密封處理，減少內部噪(zao)(zao)音(yin)泄漏。通過綜合運用這(zhe)些方法，可將運行噪(zao)(zao)音(yin)降低(di) 15 - 20 分(fen)貝。
