摘　　要：设计一套单级轴流风机试验台,包括风机进出口风道及可调风门,并在风机进口叶轮区域加装高频动态压力变送器等参数监控仪表,实现风机调整过程中该区域压力信号的变化趋势监测。将风机运行状态从稳定区间调整至易失速区域,筛选叶轮区域特定的压力变化过程和特征,以此推测风机失速前兆特征。Design a single stage axial flow fan test bench,including inlet and outlet air ducts and adjustable dampers,and install parameter monitoring instruments such as high-frequency dynamic pressure transmitters in the impeller area of the fan inlet to monitor the trend of pressure signal changes in this area during the fan adjustment process.Adjust the operating status of the fan from a stable range to a stall prone area,screen specific pressure changes and characteristics in the impeller area,and infer the precursor characteristics of fan stall.
