10 Most Overlooked Details in Air Compressor Maintenance! #8 Extends Equipment Life by 3 Years
CHANUN air compressor
The following is a summary of expert insights from Chenen Air Compressor Factory. These practical tips can help your air compressor run for an extra 5,000 hours.
### 01 Daily Maintenance: These Details Determine Equipment Lifespan
① Correct Way to Check Oil Level
❌ Wrong approach: Check immediately after shutdown
✅ Correct method: Wait 5 minutes after shutdown for the oil to return, then check the midpoint of the oil sight glass
② Optimal Time to Drain Condensate
• Summer: Drain every 8 hours
• Winter: Drain every 4 hours
• Rainy season: Increase drainage frequency appropriately
③ Belt Tension Adjustment Tip
Press the middle of the belt with your thumb; the ideal deflection is 10-15mm. Too tight increases bearing load, too loose reduces transmission efficiency.
### 02 Monthly Must-Dos: Four Key Points You Shouldn’t Skip
① Air Filter Cleaning
• Clean from the inside out after removal
• Pressure should not exceed 0.3MPa
• Replace after cleaning 5 times
② Cooler Cleaning
• Use specialized cleaning agents
• Clean fin gaps thoroughly
• Ensure it is completely dry before reinstalling
③ Connection Tightening Check
Retighten to standard torque:
• Intake pipe connection: 35-40N·m
• Exhaust pipe connection: 45-50N·m
• Base bolts: 60-65N·m
④ Motor Bearing Lubrication
Use specialized grease; the filling amount should be 1/3 to 1/2 of the bearing space. Overfilling can cause overheating.
### 03 Quarterly Maintenance: These Three Components Are Most Easily Overlooked
① Minimum Pressure Valve Maintenance
Clean the valve body and check the sealing ring. Replace if wear exceeds 0.5mm.
② Thermostatic Valve Calibration
Test opening at 60°C and 80°C. Replace if the deviation exceeds ±5°C.
③ Oil Pipeline Cleaning
Circulate a specialized cleaning agent for 2 hours until clean oil flows out.
### 04 Annual Major Maintenance: Save Money and Effort with This Process
①Minimum Pressure Valve Maintenance
Clean the valve body and check the sealing ring. Replace if wear exceeds 0.5mm.
② Thermostatic Valve Calibration
Test opening at 60°C and 80°C. Replace if the deviation exceeds ±5°C.
③ Oil Pipeline Cleaning
Circulate a specialized cleaning agent for 2 hours until clean oil flows out.
### 05 On-Site Q&A
Q: How often should engine oil be changed?
A: Generally, mineral oil every 2,000 hours, semi-synthetic every 3,000 hours, and full-synthetic every 4,000 hours. Reduce intervals by 30% in dusty environments.
Q: What to do when the equipment noise increases?
A: Troubleshoot in the following order:
1. Check foundation tightness
2. Inspect belt tension
3. Check bearings and couplings
4. Troubleshoot intake valve issues
Q: How to resolve high exhaust temperature?
A:
• Clean the cooler (solves 50% of issues)
• Check oil level and quality
• Clean the fan filter
• Improve ventilation in the equipment room
