Meta Description
Discover 16 common causes of high temperature in screw air compressors. Learn how to troubleshoot and improve performance with air compressors, nitrogen generators, and oxygen systems.
1. Why Do Air Compressors Overheat in Summer?
During summer, high ambient temperatures reduce cooling efficiency and increase system load, leading to:
- High temperature alarms
- Unexpected shutdowns
- Reduced efficiency
This is especially critical in systems connected to nitrogen generators and oxygen generators, where temperature directly affects gas quality.
2. 16 Common Causes of High Temperature
1. Low Lubricating Oil
Insufficient oil leads to poor cooling and rapid overheating.
2. Oil Stop Valve Failure
No oil supply during loading → instant overheating.
3. Oil Filter Blockage
- Severe: oil starvation
- Mild: reduced cooling efficiency
4. Thermostatic Valve Failure
Oil bypasses cooler → temperature rises quickly.
5. Insufficient Oil Injection
Reduces cooling capacity.
6. Oil Degradation
Old oil loses viscosity and heat transfer ability.
7. Oil Cooler Fouling
Temperature difference < 5°C indicates blockage.
8. Cooling System Issues
- Water-cooled: high water temperature
- Air-cooled: poor ventilation
9. Radiator Problems
Dust or corrosion reduces heat dissipation.
10. Poor Exhaust Duct Design
Hot air cannot be discharged efficiently.
11. Faulty Temperature Sensor
Replace to confirm.
12. Airend Bearing Wear
Leads to friction and heat buildup.
13. Incorrect Lubricating Oil
Wrong oil reduces performance.
14. Air Filter Blockage
Causes overload and overheating.
15. High System Pressure
Increases load and temperature.
16. Oil Separator Blockage
Raises internal pressure → overheating.
3. System-Level Solution
Provide stable compressed air and cooling.
Require clean and stable compressed air.
Highly sensitive to temperature and oil contamination.
4. Expert Recommendations
- Replace oil and filters regularly
- Improve ventilation
- Maintain cooling systems
- Control ambient temperature
5. Conclusion
verheating is usually caused by imbalance in:
👉 Lubrication + Cooling + Load
A complete system solution is the key.
