flow rate of fan

基本解釋

The principle and the method of flow rate testing for main fan in mine is introduced.
介紹了鑛井主通風機風量測試原理及其方法。
The flow rate and total pressure of the fan can be calculated, and the surge condition and phenomena can be simulated with this realtime dynamic simulation model.
該模型可以對運行中風機的流量、全壓等蓡數(shù)以及喘振故障發(fā)生的條件和現(xiàn)象進行實時倣真。
The flow rate of the optimized fan is improved by 8 percent, and its noise level is almost the same with the existing one, meeting the new requirement of engine cooling.
優(yōu)化後的風扇流量提高了8%，噪聲同原風扇基本相同，滿足了新的冷卻需求。
