還有一個問題就是經常會(hui)遇見(jian)的(de)(de)(de)(de)問題,是什么(me)呢?那就是噪音(yin)(yin)問題,消防排煙(yan)風(feng)(feng)機(ji)箱(xiang)的(de)(de)(de)(de)噪音(yin)(yin)過大的(de)(de)(de)(de)起因(yin)(yin),消防排煙(yan)風(feng)(feng)機(ji)箱(xiang)與風(feng)(feng)管(guan)(guan)(guan)(guan)外殼(ke)發(fa)生共振(zhen)而發(fa)生噪音(yin)(yin),風(feng)(feng)管(guan)(guan)(guan)(guan)與風(feng)(feng)機(ji)外殼(ke)的(de)(de)(de)(de)內(nei)(nei)面接縫(feng)處要平坦,避免毛糙(cao)不(bu)平,形(xing)成(cheng)撕裂聲(sheng)(sheng)。3c消防排煙(yan)風(feng)(feng)機(ji)在額(e)定轉速下(xia),在工作區(qu)域內(nei)(nei),通(tong)風(feng)(feng)機(ji)的(de)(de)(de)(de)實測壓力曲線與說明書中(zhong)給定的(de)(de)(de)(de)曲線應滿(man)足下(xia)列規定。消防排煙(yan)風(feng)(feng)機(ji)風(feng)(feng)管(guan)(guan)(guan)(guan)與風(feng)(feng)機(ji)外殼(ke)的(de)(de)(de)(de)內(nei)(nei)面接縫(feng)處要平坦,避免毛糙(cao)不(bu)平,形(xing)成(cheng)撕裂聲(sheng)(sheng)。 而因(yin)(yin)為(wei)連續的(de)(de)(de)(de)管(guan)(guan)(guan)(guan)路會(hui)發(fa)生共振(zhen),使(shi)(shi)細微(wei)(wei)的(de)(de)(de)(de)聲(sheng)(sheng)音(yin)(yin)變(bian)大,形(xing)成(cheng)更大的(de)(de)(de)(de)噪音(yin)(yin)。 而因(yin)(yin)為(wei)連續的(de)(de)(de)(de)管(guan)(guan)(guan)(guan)路會(hui)發(fa)生共振(zhen),使(shi)(shi)細微(wei)(wei)的(de)(de)(de)(de)聲(sheng)(sheng)音(yin)(yin)變(bian)大,形(xing)成(cheng)更大的(de)(de)(de)(de)噪音(yin)(yin)。 找(zhao)到這一起因(yin)(yin)咱(zan)們可能(neng)在計劃時,可能(neng)在風(feng)(feng)管(guan)(guan)(guan)(guan)外面覆以防音(yin)(yin)資料,來降落噪音(yin)(yin)。
