Troubleshooting Pneumatic Conveying Systems

 

1. Blower Package:

• Blowers provide the necessary volume of air and pressure for the system.

• Check for consistent blower speed and pressure relief valve behavior.

• Gauge fluctuations may indicate rotary valve wear or low velocity.

2. Convey Line:

• Elbows are wear points and can impact system performance.

• Avoid excessive bends and monitor line pressure.

• Feel the line to assess material flow.

3. Rotary Valves / Airlocks:

• These act as the “revolving door” of the system.

• Inspect for proper pressure separation and functionality.

4. Filter Receivers / Bin Vents:

• Not dust collectors; they separate air and material.

• Monitor filter differential pressure.

• Ensure efficient bag cleaning cycles.
