風機的轉速越高真的越不安全嗎?

  風機既然是旋轉機械,那么風機的轉速是風機設計中的重要參數,這些年,對風機轉速的選擇在某些行業還是存在一些爭議,亞博App手機版和大家討論一下風機的轉速到底如何確定比較合理。

2、風機的轉速對風機的性能有啥影響?

風機的轉速越高,風機能提供的壓力和流量越大

3、風機的設計轉速如何確定呢?

  從風機性能的角度來看,轉速當然是越高越好,但從材料、結構設計的角度來看,過高的轉速對材料的強度要求越高,因此轉速的設計是需要綜合風機的性能、風機的機械結構、材料等綜合來考慮的,是一個比較負責的各個方面平衡的過程。

  fengjizaizuojixieshejixuyaozonghekaolv,zhuyaokaolvyixiafangmian:

  ①風機的性能

  ②材料的選擇

  ③強度的計算

  ④結構的設計

  ⑤制造工藝的合理性

  ⑥成本是否經濟

  ⑦客戶的使用方便性

  ⑧風機的磨損

  ⑨安全可靠性

  那有些人會問了,同樣的風機轉速降低之后,噪音確實小了啊,不要忘記了,轉速降低之后,風機的出力也變小了,噪音當然相應降低了,但這是風機的負荷時滿足不了你的需求的。
