風機是依靠輸入的機械能，提高氣體壓力并排送氣體的機械，它是一種從動的流體機械。風機是我國對氣體壓縮和氣體輸送機械的習慣簡稱，通常所說的風機包括通風機，鼓風機，壓縮機以及羅茨鼓風機，離心式風機,回轉式風機,水環式風機,但是風機通風管批發不包括活塞壓縮機等容積式鼓風機和壓縮機。氣體壓縮和氣體輸送機械是把旋轉的機械轉換為氣體壓力能和動能，并將氣體輸送出去的機械。風機主要由風葉、百葉窗、開窗機構、電機、皮帶輪、進風罩、內框架、機殼、安全網等部件組成。開機時由電機驅動風葉旋轉，并使開窗機構打開百葉窗排風。風機通風管停機時百(bai)葉窗自動關閉。風(feng)(feng)機廣泛用于工廠、礦井、隧(sui)道、冷(leng)卻(que)塔、車輛、船舶和(he)建筑物(wu)的(de)通(tong)風(feng)(feng)、排塵和(he)冷(leng)卻(que)；鍋爐(lu)(lu)和(he)工業(ye)爐(lu)(lu)窯(yao)的(de)通(tong)風(feng)(feng)和(he)引風(feng)(feng)；空氣(qi)調節設備(bei)和(he)家用電(dian)器設備(bei)中的(de)冷(leng)卻(que)和(he)通(tong)風(feng)(feng)；谷物(wu)的(de)烘(hong)干(gan)和(he)選送(song)；風(feng)(feng)洞風(feng)(feng)源和(he)氣(qi)墊船的(de)充氣(qi)和(he)推進等。
