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)增強(qiáng)葉柵的氣動(dòng)力栽荷，降低圓周速度。對(duì)于風(fēng)機(jī)采用強(qiáng)前向葉片，且多葉片葉輪有利于增大葉柵的氣動(dòng)力載荷，在得到同樣風(fēng)量風(fēng)壓情況下，葉輪葉片外圓上圓周速度可使風(fēng)機(jī)噪聲明顯降低。 (2)合理的蝸舌間隙和蝸舌半徑。當(dāng)氣流與葉片做相對(duì)運(yùn)動(dòng)時(shí)，葉片后緣的氣流尾跡中速度及壓力均小于主流區(qū)，使葉柵后的氣流速度與壓力分布皆不均勻，這種不均勻的氣流在旋轉(zhuǎn)，由于在動(dòng)葉的氣流出口有蝸舌存在，則這種非穩(wěn)定流動(dòng)與蝸舌相互作用將產(chǎn)生噪聲，距離噪聲愈近噪聲愈烈，通常適當(dāng)取較大的風(fēng)舌前端半徑可以降低離心風(fēng)機(jī)的旋轉(zhuǎn)噪聲與渦流噪聲。</p><p style="text-indent:25px">離心風(fēng)機(jī)設(shè)計(jì)中需要考慮到的幾個(gè)重要問題？為了便于區(qū)別和選用，因而我們通常是將離心風(fēng)機(jī)設(shè)備的葉片分為這樣幾種類型：強(qiáng)后彎葉片(水泵型)、后彎圓弧葉片、后彎直葉片、后彎機(jī)翼形葉片；徑向出口葉片、徑向直葉片；前彎葉片、強(qiáng)前彎葉片(多翼葉)。同時(shí)還要注意選擇適合的葉片數(shù)量。總的來說，我們?cè)谠O(shè)計(jì)離心風(fēng)機(jī)時(shí)，其中必須要考慮到的一個(gè)重要問題就是把握好葉輪葉片出口角的確定。根據(jù)葉片出口角的不同，可將葉片分成三種型式即后彎葉片、徑向出口葉片和前彎葉片。三種葉片型式的葉輪，目前均在離心風(fēng)機(jī)設(shè)計(jì)中應(yīng)用。根據(jù)不同的風(fēng)量和風(fēng)壓，來選擇相應(yīng)的風(fēng)機(jī)。</p><div
