I. Equipment Operating Status
1. Abnormal Sounds: Unusual noises, vibrations, or increased noise during operation may indicate worn or loose components.
2. Abnormal Temperature: Overheating of the motor or critical components may be due to overload or poor heat dissipation.
3. Unstable Operation: Fluctuations in speed, uneven oscillation, or automatic shutdown may be related to sensor or control system malfunctions.
II. Key Component Inspection
1. Sanding Belt/Media: Check for belt misalignment, wrinkles, or wear; ensure the media is sufficient or unevenly distributed.
2. Limit Switches: Test the reliability of limit switches to prevent equipment damage due to malfunction.
3. Seals: Check for worn or aged seals to prevent material leakage.
III. Performance Indicators
1. Output Quality: Uneven output particle size or excessive surface roughness may be due to insufficient grinding media or improper equipment parameter settings.
2. Energy Consumption Changes: A sudden increase in energy consumption may be due to motor overload or component wear.
IV. Maintenance Records
1. Regular Inspections: According to the maintenance plan, check equipment operating data and component wear.
2. Fault History: Record historical faults and repair details, and analyze fault frequency and causes.
V. Operating Procedures
1. Operational Errors: Check whether operators are operating according to procedures to avoid equipment damage due to misoperation.
2. Environmental Factors: Check whether the working environment meets equipment requirements (e.g., temperature, humidity, ventilation).
