Factors affecting the surge of high-speed air suspension fans

Common factors causing fan surge include butterfly valve misoperation, control system failure, and operator misoperation.

The main manifestations of fan surge are significant fluctuations in flow rate, filtration pressure difference, and power, as well as severe vibration and abnormal noise in the fan,

Fan surge can cause blade breakage or mechanical component damage. Once a running fan is found to have entered the surge zone, the fan should be adjusted immediately.
