摘要:
FFU風機的作用
  FFU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。風機是中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,風力發電機。
  FFU風機廣泛用于工廠、礦井、隧道、冷卻塔、車輛、船舶和建筑物的通風、排塵和冷卻,鍋爐和工業爐窯的通風和引風;空氣調節設備和家用電器設備中的冷卻和通風;谷物的烘干和選送,風洞風源和氣墊船的充氣和推進等。
  FFU風機剛開始工作時軸承部位的振動很小,但是隨著運轉時間的加長,風機內粉塵會不均勻的附著在葉輪上,逐漸破壞風機的動平衡,使軸承振動逐漸加大,一旦振動達到風機允許的*大值11mm/s時(用振幅值表示的*大允許值如下),風機必須停機修理(**粉塵堆積,重做動平衡)。因為這時已是非常危險的,用戶千萬不可強行使用。在風機振動接近危險值時,有測振儀表的會報警。
