Abstract: Due to complex rotor structure and multiple rotatable parts, there is larger risk of surge for axial flow fan; and the damage caused by the surge is also larger. According to the practical situation of the site, the surging reasons of the fan were analyzed. Some countermeasures were adopted, and the probability of the fan surge was decreased obviously.
