How to resolve frequent tripping issues in corrosion-resistant fans?

Users have reported that corrosion-resistant fans frequently trip during operation, severely compromising their efficient performance.

To swiftly resolve this issue, it is essential to promptly identify the root causes and prevent frequent tripping that could damage the fans.

1.  Trip caused by excessive pipeline length: Even with valves closed, resistance exceeds the fan's tolerance threshold.

2. Excessive voltage supply to the corrosion-resistant fan causes tripping.

3. Low resistance in dust collection equipment or ductwork.

4. Incomplete opening of the fan damper leads to tripping.

5. An overly large cross-sectional area in the outlet ducting causes excessive shaft power demand, resulting in motor overload and current exceeding rated values.

6. The dust removal equipment's ducting is relatively short, necessitating tighter closure of the gate valve (actually a butterfly valve, not fully closed). This results in insufficient system resistance.

Corrosion-resistant fans frequently trip during operation due to the aforementioned multiple causes.

Therefore, personnel can reference these causes to quickly identify the root cause of the issue and address it promptly. This prevents further damage from time delays and ensures the normal operation of the mechanical equipment.
