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,但是防火閥廠家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。防火閥停機(ji)時百葉窗自(zi)動關閉(bi)。風(feng)機(ji)廣泛用于工廠、礦井、隧道、冷卻(que)塔、車輛、船(chuan)舶和建筑物(wu)(wu)的(de)(de)通(tong)風(feng)、排塵和冷卻(que)；鍋爐(lu)和工業(ye)爐(lu)窯(yao)的(de)(de)通(tong)風(feng)和引風(feng)；空氣(qi)調節設備和家(jia)用電器(qi)設備中的(de)(de)冷卻(que)和通(tong)風(feng)；谷(gu)物(wu)(wu)的(de)(de)烘干和選送；風(feng)洞風(feng)源和氣(qi)墊船(chuan)的(de)(de)充氣(qi)和推進等。
