style="text-indent:25px">軸流式風(fēng)機(jī)如何降低噪聲？具體降噪方法如下：(1) 蝸舌傾斜。風(fēng)機(jī)葉輪葉柵氣流的周期性脈動(dòng)速度所產(chǎn)生的周期性脈動(dòng)氣動(dòng)力也使蝸舌相互作用產(chǎn)生旋轉(zhuǎn)噪聲，此噪聲大小與脈動(dòng)氣動(dòng)力的劇烈程度及渦舌的迎風(fēng)面積有關(guān)，把蝸舌做成傾斜式，則同相位的脈動(dòng)氣動(dòng)力的作用面積小了，輻射的噪聲也就減小了。 (2)葉輪入(出)口處加紊流化裝置。在風(fēng)機(jī)葉輪葉片的入口或出口處加紊流化裝置(金屬網(wǎng))可以使葉片背面的層流附面層立即轉(zhuǎn)換成紊流附面層，推遲葉片背面附面層的分離，甚至不分離，葉片后緣裝上網(wǎng)，網(wǎng)后的氣流速度與壓力梯度能迅速變均勻，若網(wǎng)在渦區(qū)中則可將渦區(qū)較大縮小,可進(jìn)一步減噪.盡量使燃油或煤燃燒充分，減少炭黑，適當(dāng)?shù)靥岣吲艧煖囟群瓦M(jìn)風(fēng)溫度，以避免煙氣中德硫在空預(yù)器中德結(jié)露?？諝鈨艋黠L(fēng)機(jī)廠(chǎng)家</p><p
