Analysis of Trigger Causes for Explosion-Proof and Corrosion-Resistant Axial Fans:

Risk of Triggering: The triggering of an explosion-proof and corrosion-resistant axial fan can not only damage the fan components but also cause damage to the core component—the motor—leading to significant losses.

Relation to Outlet Damper Opening: When the outlet damper of the explosion-proof and corrosion-resistant axial fan is too small, the airflow generated by the fan cannot be discharged in time, causing the system’s air pressure to become too high, ultimately triggering a fault. In this case, the damper opening can be appropriately adjusted. If adjustment is ineffective, fan replacement should be considered.

Pipeline Issues: If the dust removal pipe of the explosion-proof and corrosion-resistant axial fan is too short, and the valve is closed, insufficient system resistance may prevent the fan motor from starting properly. The pipeline should not be too long, as this would affect the fan’s performance and increase the risk of failure.

Electrical Faults: Electrical faults may cause excessive axial output from the fan, leading to motor overload, with the current exceeding the rated value, thus triggering a fault.
