What are the precautions when using a pneumatic conveying system?

I. Equipment Selection and Installation

1. Material Compatibility
Select equipment based on material properties (humidity, particle size, abrasiveness). Avoid conveying sticky, caking, or high-temperature materials.

1. Pipe Design Standards:

1. Minimum bend radius: ≥1.5 meters

2. Horizontal pipe length: ≤300 meters (direction adjustment required beyond 200 meters)

3. Tilt angle for inclined pipes: ≤5° to prevent material deposition

2. Connection Requirements: Use concentric pipe installations and avoid welding protrusions.

II. Operational Specifications and Parameter Control

1. Startup Sequence

1. Activate the blower first and verify pressure gauge readings (normal range: 0-0.02 MPa).

2. Start the feeder and adjust frequency to prevent pipe blockages.

2. Conveying Speed Management
Balance kinetic energy and blockage risks. Avoid abrupt changes in material proportioning.

3. Shutdown Procedure
Follow the sequence: "Stop feeding → Close feeder → Shut down blower." Clear residual materials from pipes afterward.

III. Safety Protection and Emergency Response

1. Protective Measures

1. Equip systems with overload protection, safety switches, and electrostatic grounding.

2. Use conductive pipe materials and regularly clean dust accumulation.

2. Emergency Protocols

1. Blower Pressure/Current Overload: Immediately shut down and inspect for blockages.

2. Dust Collector Malfunction: Delay blower shutdown by 10-20 seconds if bulging/leakage occurs.

3. Ash Discharge Blockage: Clear obstructions by tapping pipes without full system shutdown.

IV. Maintenance and Inspections

1. Daily Checks

1. Inspect electrical circuits, drive systems, and pipe sealing.

2. Monthly Maintenance

1. Lubricate drive components and clean filters.

3. Critical Component Replacement

1. Focus on bend sections and acceleration zones prone to blockages.

2. Replace worn nozzles or diffusers promptly and ensure insulation integrity.

Conclusion
Pneumatic conveying systems represent a cutting-edge solution for material handling.

 As technology advances, these systems will continue to optimize operational efficiency and sustainability across industrial sectors.
