Common Faults and Solutions in Drum Production Lines

Common faults in drum production lines primarily involve mechanical wear, electrical system abnormalities, load and balance issues, as well as installation and maintenance defects. Below is a categorized explanation of fault symptoms, causes, and solutions based on typical scenarios.

Wear and Damage of Mechanical Components: Bearings may become stiff or jammed due to insufficient lubrication or prolonged friction, leading to wear. Solutions include regular inspection of lubrication conditions and application of high-temperature-resistant grease; replacement of bearings in severe cases. Drum surface wear may result from foreign objects or material issues, requiring debris removal and re-treading; replacement of drums when wear is severe. Wear on transmission belts or gears can cause transmission abnormalities, necessitating timely adjustment or replacement of transmission components.

Electrical system failure: Equipment failure to start or shutdown during operation is often caused by power line faults, motor overload, or abnormal control circuitry. Troubleshooting requires inspecting wiring connections, testing insulation resistance (minimum requirement ≥0.5MΩ), monitoring motor current, and clearing cooling channels. For overload conditions, install a current transformer for early warning. Motor overheating or winding short circuits require maintenance or replacement. Temperature sensor inaccuracies can affect control precision, and calibration can optimize drying performance.

Load Abnormality and Balance Issues: Uneven material distribution or overloading can cause drum deformation, bending, or rotational imbalance. Solutions include optimizing material distribution to avoid clumping and blockage, pre-processing materials with high moisture content, adjusting hot air parameters to ensure uniform drying, splitting materials or replacing drums with higher load-bearing capacity when limits are exceeded, and correcting or replacing severely deformed drums. Belt slippage is often due to insufficient friction or tension, which can be resolved by reapplying rubber coating, cleaning surface oil stains, and adjusting the tensioning device.

Improper Installation and Maintenance: Non-level installation or lack of maintenance can accelerate wear. Use a level to ensure installation accuracy, clean the drum surface and interior regularly to prevent debris entry, and lubricate key components periodically. Address safety risks such as poor electrical grounding or excessive mechanical vibration by conducting regular insulation resistance and vibration parameter inspections, and perform major repairs when necessary.

Fault Prevention and Optimization: Establish a regular maintenance schedule, including daily cleaning, weekly lubrication, and monthly inspection of motors and gears, to reduce failures. Combined with smart monitoring technologies (such as sensors for real-time temperature, vibration, and current monitoring), it enables fault early warning and enhances operational stability.
