What are the causes of air compressor overheating failures?

What causes overheating in air compressors? Let Granklin Air Compressor specialists explain in detail!

Overheating Analysis:
Air compressors may overheat during prolonged overload operation in daily use.

Symptoms of Overheating:
1. Excessively high exhaust temperature
2. Abnormal heat in operating components

Main Causes:
1. Malfunction of vent valves or unloading valves
2. Severe air brake system leaks
3. Insufficient oil supply to moving parts or cylinder scoring

Troubleshooting Methods:
1. After depressurizing the intake, inspect the pressure relief valve assembly. Clean or replace seized components. Address clogged/unresponsive unloading valves through cleaning, repair, or replacement.

2. Examine all brake system components and pipelines for integrity.

3. Resolve overheating caused by poor piston-cylinder lubrication, insufficient clearance, or scoring by inspecting, repairing, or replacing faulty parts.
