A corrosion-resistant axial flow fan

Abstract

This utility model provides a corrosion-resistant axial flow fan, belonging to the field of fan technology. It solves the technical problems of existing fans being prone to corrosion. This corrosion-resistant axial flow fan includes a fan casing, a motor, fan blades, and a support frame. A fixed shaft is fixedly connected to the support frame. The motor includes a stator assembly and a rotor assembly, which are integrally formed with the fixed shaft. The fixed shaft has an upper cover and a lower cover, forming a receiving cavity between them. The rotor assembly and stator assembly are located within the receiving cavity, and the rotor assembly is fixedly mounted by the upper and lower covers. The fixed shaft includes a first fixing part and a second fixing part, with the stator assembly located between the first and second fixing parts. A first bearing is installed between the first fixing part and the upper cover, and a second bearing is installed between the second fixing part and the lower cover. The fan blades and the lower cover are integrally formed. This utility model solves the problem of motors being easily corroded when exposed to airflow in the duct, extending the service life of the motor and the entire machine, and significantly reducing maintenance costs and the risk of downtime due to corrosion.
