Description

Technical Field

[0001] The utility model belongs to the technical field of explosion-proof fans, in particular to an explosion-proof axial flow fan. Background Art

[0002] Explosion-proof fans are designed to cope with gas environments that are prone to ignition and explosion, such as gas filling stations, fire ventilation, etc. Currently, explosion-proof fans on the market mainly adopt the protection of casing explosion isolation and air inlet and outlet ends, and use special materials and structures to ensure safe operation in environments where sparks or static electricity may occur, thereby avoiding explosion accidents.

[0003] There are some technical defects and deficiencies in the application of explosion-proof fans. First, since all fan parts in contact with gas must be made of non-ferrous materials, generally aluminum parts are used, so this type of fan can only work below 100 degrees Celsius. Secondly, explosion-proof fans require special protective treatment, which puts higher requirements on the selection and maintenance of motors.

[0004] During operation, if the explosion-proof fan has insufficient air volume, it may be caused by the air inlet being blocked or the fan blades rotating in the incorrect direction. These problems need to be checked and handled in time to ensure the normal operation of the fan. Utility Model Content
