水(shui)泵(beng)(beng)房噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)是由水(shui)泵(beng)(beng)工(gong)作噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)和(he)電(dian)(dian)機(ji)(ji)噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)引(yin)(yin)起(qi)的(de)綜合噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)源(yuan)。水(shui)泵(beng)(beng)工(gong)作噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)主(zhu)要(yao)包括：水(shui)泵(beng)(beng)本(ben)身運(yun)行(xing)(xing)(xing)的(de)噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)、水(shui)泵(beng)(beng)運(yun)行(xing)(xing)(xing)引(yin)(yin)起(qi)的(de)管道諧振噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)、水(shui)泵(beng)(beng)運(yun)行(xing)(xing)(xing)引(yin)(yin)起(qi)的(de)水(shui)流運(yun)動和(he)撞擊噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)。作為電(dian)(dian)機(ji)(ji)噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)，主(zhu)要(yao)有空氣(qi)(qi)動力(li)性(xing)噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)、機(ji)(ji)械性(xing)噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)和(he)電(dian)(dian)磁(ci)噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)三(san)部(bu)分。當電(dian)(dian)機(ji)(ji)工(gong)作時，冷卻空氣(qi)(qi)的(de)氣(qi)(qi)流噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)加上風(feng)扇高(gao)速旋轉(zhuan)的(de)葉片噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)組(zu)成空氣(qi)(qi)動力(li)性(xing)噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)。機(ji)(ji)械噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)包括軸承(cheng)噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)及(ji)電(dian)(dian)機(ji)(ji)轉(zhuan)子不(bu)平衡轉(zhuan)子受“溝槽諧波力(li)”作用(yong)等引(yin)(yin)起(qi)的(de)結構振動而產生的(de)噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)
水泵房噪聲是由水泵工作噪聲和電機噪聲引起的綜合噪聲源。
產品(pin)詳情
水泵工作噪聲主要包括：水泵本身運行的噪聲、水泵運行引起的管道諧振噪聲、水泵運行引起的水流運動和撞擊噪聲。
作為電機噪聲，主要有空氣動力性噪聲、機械性噪聲和電磁噪聲三部分。當電機工作時，冷卻空氣的氣流噪聲加上風扇高速旋轉的葉片噪聲組成空氣動力性噪聲。機械噪聲包括軸承噪聲及電機轉子不平衡轉子受“溝槽諧波力”作用等引起的結構振動而產生的噪聲。電磁噪聲是由定子與轉子之間交變電磁引力、磁滯伸縮引起的泵房噪聲向外傳遞的主要途徑是空氣傳遞和固體傳聲。
空(kong)氣(qi)聲(sheng)(sheng)處理(li)(li)空(kong)氣(qi)聲(sheng)(sheng)隔聲(sheng)(sheng)在水泵(beng)(beng)噪(zao)聲(sheng)(sheng)治理(li)(li)方面(mian)相對容易，水泵(beng)(beng)產生的(de)(de)空(kong)氣(qi)聲(sheng)(sheng)一般噪(zao)聲(sheng)(sheng)不超過85dB(A)，而(er)水泵(beng)(beng)房與居民(min)室內(nei)至少有一層樓(lou)板的(de)(de)間隔。一般120mm現澆混凝(ning)土的(de)(de)空(kong)氣(qi)聲(sheng)(sheng)隔聲(sheng)(sheng)量都大(da)于(yu)52dB，對隔絕水泵(beng)(beng)的(de)(de)空(kong)氣(qi)聲(sheng)(sheng)相當有利(li)。但現在對居民(min)室內(nei)的(de)(de)聲(sheng)(sheng)環境有較嚴(yan)格的(de)(de)要求，所以若泵(beng)(beng)房與居民(min)僅相隔一層樓(lou)板的(de)(de)距(ju)離(li)時，需要對隔聲(sheng)(sheng)進(jin)行以特殊處理(li)(li)，常用的(de)(de)方法有加隔聲(sheng)(sheng)罩、隔聲(sheng)(sheng)吊頂、室內(nei)加吸(xi)聲(sheng)(sheng)等。
