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.
