1. 9 Common Faults & Solutions
- Frequent start-stop: Match air receiver, repair leaks, adjust pressure switch (differential pressure ≥0.15MPa);
- High discharge temperature: Inspect cooling fan, clean cooler, refill/replace lubricating oil;
- Excessive oil in air: Replace oil separation filter, overhaul head seal, control oil level (1/2-2/3);
- Abnormal pressure drop: Repair leaks, overhaul blowdown valve, calibrate pressure gauge (accuracy ≥1.6 class);
- Pipeline vibration/noise: Reinforce supports (add shock pads), install flexible connectors, optimize pipeline;
- Dryer dehumidification failure: Repair leaks/refill refrigerant, clean/replace filters, control room temp (5-40℃);
- Failure to start: Check power (380V±10%), overhaul motor, replace pressure switch;
- Insufficient pneumatic equipment pressure: Replace suitable pipe diameter, adjust pressure reducing valve, clean pipeline;
- Dirty environment: Install dust filters, improve floor waterproofing, make regular cleaning plans..
2. Key O&M Principles
- Regular inspection: Monitor pressure/temperature daily/weekly/monthly;
- Professional maintenance: Qualified personnel for pressure vessels/high-voltage motors;
- Record keeping: Establish equipment accounts for faults and handling.
