How to maintain PVC conduit production line

1. Daily Cleaning & Surface Maintenance

· Regular Dust Removal: Clean dust, debris, and residual raw materials from the surface of equipment (e.g., extruder, traction unit, cutting device) using a soft cloth or compressed air to prevent accumulation that may affect heat dissipation or cause mechanical jamming .

· Die & Screw Cleaning: After daily production, disassemble the extrusion die and screw to remove leftover PVC residue. Use specialized cleaning agents for stubborn deposits to avoid material degradation during subsequent production.

2. Environmental Control

· Avoid Harsh Conditions:

o Keep the production line away from direct sunlight, thermal radiation, excessive moisture, dust, and corrosive gases. Corrosive environments can damage electronic components (e.g., PLC, sensors) and cause short circuits or poor contact .

o Isolate the line from high-vibration equipment (e.g., punch machines) to prevent structural loosening of precision parts like the calibration sleeve or traction track .

3. Electrical System Protection

· Stable Power Supply: Use a dedicated power line or voltage stabilizer to avoid voltage fluctuations (>±10%) and transient interference, which can disrupt the PLC control system and motor operation .

· Regular Circuit Checks: Inspect wiring connections, fuses, and contactor (e.g., Schneider components) for looseness or overheating. Clean electrical cabinets monthly to prevent dust buildup .

· Battery & Software Maintenance: For PLC systems, check battery status regularly (e.g., via alarm prompts) to avoid loss of system parameters. If the line is idle, power it on once or twice weekly for 1 hour to keep electronic components dry and detect potential software issues .

4. Core Component Maintenance

5. Operational & Fault Management

· Strict Procedure Adherence: Ensure operators follow standardized workflows (e.g., pre-startup checks for material feeding and temperature settings). Prohibit unauthorized parameter adjustments on the PLC touchscreen .

· Fault Handling: When malfunctions occur (e.g., extrusion blockage, size deviation), operators must preserve the scene and report details (time, symptoms, parameter changes) to maintenance personnel for targeted troubleshooting .

6. Long-Term Idle Preservation

· Scheduled Power-On: If production is paused for over a week, run the line empty for 1 hour twice weekly to generate heat and reduce internal humidity, preventing mold growth in cooling tanks and moisture damage to electronics .

· Component Protection: Cover exposed parts (e.g., die, traction wheels) with dust-proof sheets. Drain water from cooling tanks and clean pipelines to avoid scaling .

Key Principle: Regular maintenance focuses on preventive care (e.g., cleaning, lubrication, calibration) and environmental control to extend equipment lifespan, reduce downtime, and ensure consistent product quality. Adherence to the 1-year warranty terms for core components (bearings, motors, PLC) is also recommended .
