通风机不稳定工况的理论研究及预防措施

Ventilator Instability Modes of Theory Research and Prevention Measures

从叶片的结构和气流的流动状态2个方面,详细介绍了煤矿通风机的不稳定工况机理,并详细阐述了通风机不稳定工况的危害。在理论分析的基础上,提出了针对不稳定工况的预防措施,丰富了通风机不稳定工况的理论研究,并为现场实际工作提供了切实有效、可行的不稳定工况防治依据。

This paper from two aspects of the structure of the blade and air flow state, detailed introduces the instability of the coal mine ventilator working mechanism, and expounds the instability of the dangers of the ventilator working condition. On the basis of theoretical analysis, the paper puts forward the the preventive measures, enriched the ventilator is not stable condition theory research, and provides the practical, effective and feasible not stable state control basis to the actual work.
