Air compressors serve as the “power heart” of industrial production. Inadequate daily maintenance can easily lead to breakdowns and downtime, resulting in economic losses. Industry data shows that proper daily maintenance can reduce failure risks by over 70% and extend equipment lifespan by 30%. Below is a concise and practical daily maintenance guide.

Pre-Startup: 3-Minute Quick Check

 

Verify oil level in oil-injected compressors, ensuring it sits between 1/2 and 2/3 of the dipstick. Replace oil immediately if quality appears abnormal. For oil-free models, inspect lubrication coating integrity. Check for leaks at oil and air line connections. Clean dust and debris from the air intake filter surface. Eliminate potential hazards from visible damage.

 

During Operation: Real-Time Monitoring of Key Metrics

 

Monitor whether the discharge pressure remains stable and the temperature is controlled between 75-95°C. If sudden pressure changes occur or the temperature exceeds 100°C, shut down the machine for inspection. Pay attention to the operating sounds of the equipment to avoid abnormal noises or increased vibration. Check the automatic drain valve every 2-4 hours to ensure smooth condensate drainage and prevent component corrosion.

 

Post-shutdown: 5-minute final maintenance

 

After powering off, clean dust and oil residue from the unit and surrounding area to ensure unobstructed heat dissipation. Check belt tension; ideal deflection should be 10-15mm when pressed. Record daily operating hours, pressure, temperature, and other data to establish a maintenance log.

 

Avoid two common pitfalls

 

Never overfill with lubricating oil, as this increases oil consumption and component wear. Never substitute standard motor oil for specialized lubricants, as they cannot withstand high-temperature operation and will shorten equipment lifespan.

 

Industry experts advise that routine maintenance requires no complex procedures. Businesses need only clarify responsibilities and implement standardized processes to effectively reduce repair costs and lower energy consumption. Small and medium-sized enterprises may engage professional service providers for regular inspections to ensure stable equipment operation.
