風(fēng)機(jī)性能參數(shù)
風(fēng)機(jī)的性能參數(shù)主要有流量、壓力、功率，效率和轉(zhuǎn)速。另外，噪聲和振動(dòng)的大小也是主要的風(fēng)機(jī)設(shè)計(jì)指標(biāo)。流量也稱風(fēng)量，以單位時(shí)間內(nèi)流經(jīng)風(fēng)機(jī)的氣體體積表示；壓力也稱風(fēng)壓，是指氣體在風(fēng)機(jī)內(nèi)壓力升高值，有靜壓、動(dòng)壓和全壓之分；功率是指風(fēng)機(jī)的輸入功率，即軸功率。風(fēng)機(jī)有效功率與軸功率之比稱為效率。風(fēng)機(jī)全壓效率可達(dá)90％。
風(fēng)機(jī)的未來
風(fēng)機(jī)發(fā)展將進(jìn)一步提高風(fēng)機(jī)的氣動(dòng)效率、裝置效率和使用效率，以降低電能消耗；用動(dòng)葉可調(diào)的軸流風(fēng)機(jī)代替大型離心風(fēng)機(jī)；降低風(fēng)機(jī)噪聲；提高排煙、排塵風(fēng)機(jī)葉輪和機(jī)殼的耐磨性；實(shí)現(xiàn)變轉(zhuǎn)速調(diào)節(jié)和自動(dòng)化調(diào)節(jié)。
鼓風(fēng)機(jī)有兩大類，ysdzxcvb201605211一類是叫“離心式鼓風(fēng)機(jī)”，它的原理是由于風(fēng)機(jī)工作時(shí)里面的風(fēng)機(jī)葉輪高速旋轉(zhuǎn)，使風(fēng)機(jī)殼里的空氣產(chǎn)生離心力而被甩離風(fēng)機(jī)葉輪，經(jīng)過出風(fēng)口被“壓送”出風(fēng)機(jī)；而此時(shí)由于風(fēng)機(jī)葉輪周圍的空氣被甩出而產(chǎn)生“負(fù)壓”，所以“新空氣”便從進(jìn)風(fēng)口處被源源不斷地補(bǔ)充進(jìn)來，構(gòu)成了風(fēng)機(jī)的正常工作狀態(tài)；第二類是叫“軸流風(fēng)機(jī)”，它的工作原理是：由于這種風(fēng)機(jī)和電風(fēng)扇一樣，其葉片的面和風(fēng)機(jī)軸是有一個(gè)夾角的，在旋轉(zhuǎn)時(shí)，葉片把空氣順軸向往出風(fēng)口“推”，而在進(jìn)風(fēng)口處就形成了一定的負(fù)壓，新空氣也就被補(bǔ)充進(jìn)來，這樣也就保持了正常工作的狀態(tài)。
普通型軸流風(fēng)機(jī)可用于一般工廠、倉庫、辦公室、住宅內(nèi)等場所的通風(fēng)換氣，也可用于冷風(fēng)機(jī)（空氣冷卻器）、蒸發(fā)器、冷凝器、噴霧降、等等，也有礦用軸流風(fēng)機(jī)，
防腐、防爆型軸流風(fēng)機(jī)采用防腐材料及防爆措施，并匹配防爆電機(jī)，可用于輸送易爆、易揮發(fā)、具有腐蝕性的氣體，
要求軸流風(fēng)機(jī)輸送的氣體應(yīng)無顯著灰塵，無粘性和纖維物質(zhì)；電動(dòng)機(jī)直連型溫度不超過40℃，皮帶傳動(dòng)型溫度不超過60℃。輸送氣體的粉塵量不得超過150mg/m3，
軸流風(fēng)機(jī)主要由葉輪、機(jī)殼、電動(dòng)機(jī)等零部件組成，支架采用型鋼與機(jī)殼風(fēng)筒連接。其中防腐型軸流風(fēng)機(jī)葉輪、機(jī)殼均為玻璃鋼制成，其它型式軸流風(fēng)機(jī)一般采用鋼板制成。
工作原理風(fēng)機(jī)的葉輪由數(shù)十片葉片組成，它類似龐大的氣輪機(jī)的葉輪。葉輪葉片中間的空氣受到了離心力的作用，向葉輪的邊緣運(yùn)動(dòng)，在那里空氣進(jìn)入泵體環(huán)行空腔，重新從葉片的起點(diǎn)以同樣的方式再進(jìn)行循環(huán)。葉輪旋轉(zhuǎn)所產(chǎn)生的循環(huán)氣流，
以極高的能量離開氣泵以供使用。風(fēng)機(jī)采用專用電機(jī)，結(jié)構(gòu)緊湊，體積小，重量輕，噪音低，送出氣源無水無油
當(dāng)葉輪旋轉(zhuǎn)時(shí)，氣體從進(jìn)風(fēng)口軸向進(jìn)入葉輪，受到葉輪上葉片的推擠而使氣體的能量升高，然后流入導(dǎo)葉。導(dǎo)葉將偏轉(zhuǎn)氣流變?yōu)檩S向流動(dòng)，同時(shí)將氣體導(dǎo)入擴(kuò)壓管，進(jìn)一步將氣體動(dòng)能轉(zhuǎn)換為壓力能，最后引入工作管路。
軸流式風(fēng)機(jī)葉片的工作方式與飛機(jī)的機(jī)翼類似。但是，后者是將升力向上作用于機(jī)翼上并支撐飛機(jī)的重量，而軸流式風(fēng)機(jī)則固定位置并使空氣移動(dòng)。AFB0748HH 70 x 70 x 25.4 MM SERIES AFB AFB0712L AFB0724L AFB0712M AFB0724M AFB0712H AFB0724H AFB0712HH AFB0724HH AFB0712VH AFB0724VH AFB0712SH 80 x 80 x 15 MM SERIES AFB AFB0812LB AFB0824LB AFB08 AFB08 AFB0812HB AFB0824HB AFB0812HHB AFB0824HHB AFB0812VHB AFB0824VHB AFB0812SHB AFB0824SHB 80 x 80 x 20 MM SERIES AFB0812LD AFB0824LD AFB0812MD AFB0824MD AFB0812HD AFB0824HD AFB0812HHD AFB0824HHD AFB0812VHD AFB0824VHD AFB0812SHD AFB0824SHD 80 x 80 x 25.4 MM SERIES AFB AFB0805L AFB0812L AFB0824L AFB0848L AFB0805M AFB0812M AFB0824M AFB0848M AFB0805H AFB0812H AFB0824H AFB0848H AFB0812HH AFB0824HH AFB0848HH AFB0812VH AFB0824VH AFB0812SH AFB0824SH 92 x 92 x 15 MM SERIES AFB AFB0912LB AFB0912MB AFB0912HB AFB0912HHB 92 x 92 x 20 MM SERIES AFB AFB0912LD AFB0924LD AFB0912MD AFB0924MD AFB0912HD AFB0924HD AFB0912HHD AFB0924HHD AFB0912VHD AFB0924VHD 92 x 92 x 25.4 MM SERIES AFB AFB0912L AFB0924L AFB0948L AFB0912M AFB0924M AFB0948M AFB0912H AFB0924H AFB0948H AFB0912HH AFB0924HH AFB0948HH AFB0912VH AFB0924VH 120 x 120 x 25.4 MM SERIES AFB1212L AFB1224L AFB1212M AFB1224M AFB1212H AFB1224H AFB1212HH AFB1224HH AFB1212VH AFB1224VH AFB1212SH AFB1224SH 120 x 120 x 38 MM SERIES AFB AFB1212LE AFB1224LE AFB1248LE AFB1212ME AFB1224ME AFB1248ME AFB1212HE AFB1224HE AFB1248HE AFB1212HHE AFB1224HHE AFB1248HHE AFB1212VHE AFB1224VHE AFB1248VHE AFB1212SHE AFB1224SHE 172 X 150 X 25.4 MM SERIES AFB AFB1512L AFB1512M AFB1512H AFB1524L 172 X 25.4 MM SERIES AFB AFB1712L AFB1712M AFB1712H AFB1724L PART NO.
