羅茨風(feng)(feng)(feng)機(ji)(ji)(ji)含有多種(zhong)噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)源，其輻射(she)(she)噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)的(de)部位主要有：(1)進氣口和(he)出氣口輻射(she)(she)的(de)空(kong)氣動(dong)(dong)(dong)力性(xing)噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)；(2)機(ji)(ji)(ji)殼(ke)及(ji)電動(dong)(dong)(dong)機(ji)(ji)(ji)、軸(zhou)承等輻射(she)(she)的(de)機(ji)(ji)(ji)械性(xing)噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)；(3)基礎振動(dong)(dong)(dong)輻射(she)(she)的(de)固(gu)體(ti)聲(sheng)(sheng)(sheng)(sheng)(sheng)。在這幾部分(fen)噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)中，進、出口部位輻射(she)(she)的(de)空(kong)氣動(dong)(dong)(dong)力性(xing)噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(簡稱氣動(dong)(dong)(dong)噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng))較強，其它如機(ji)(ji)(ji)械噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)、電磁噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)等，在風(feng)(feng)(feng)機(ji)(ji)(ji)正常運行(xing)條件下都(dou)是次要的(de)。根據羅茨風(feng)(feng)(feng)機(ji)(ji)(ji)產生噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)的(de)頻(pin)譜分(fen)析，其特(te)點為低頻(pin)寬帶。風(feng)(feng)(feng)機(ji)(ji)(ji)的(de)氣動(dong)(dong)(dong)噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)主要由兩部分(fen)組成：即旋轉噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)和(he)渦(wo)流噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)
羅茨風機含有多種噪聲源，其輻射噪聲的部位主要有：(1)進氣口和出氣口輻射的空氣動力性噪聲；(2)機殼及電動機、軸承等輻射的機械性噪聲；(3)基礎振動輻射的固體聲。在這幾部分噪聲中，進、出口部位輻射的空氣動力性噪聲(簡稱氣動噪聲)較強，其它如機械噪聲、電磁噪聲等，在風機正常運行條件下都是次要的。根據羅茨風機產生噪聲的頻譜分析，其特點為低頻寬帶。風機的氣動噪聲主要由兩部分組成：即旋轉噪聲和渦流噪聲。本公司專業提供空調噪聲治理、冷卻塔噪聲治理、、換熱(re)站噪聲治理、柴油(you)發電機噪聲治理等(deng)項目，歡迎來(lai)電咨(zi)詢。
