1. Excessively High Ambient Temperature
The higher the ambient temperature, the higher the temperature of the air drawn into the air compressor. This increases the load on the compressor's cooling system, reducing heat dissipation performance. In some cases, this can cause a high-temperature alarm or even a shutdown. Solution: Lowering the ambient temperature and maintaining good ventilation are the primary effective solutions for overheating in air compressors.
2. Inadequate Oil Level in the Air Compressor
Inadequate oil level in the air compressor can also cause overheating. Solution: Regularly check the oil level in the oil tank. If the oil level is below the oil sight glass, add oil.
3. Dirty and Clogged Oil Filter
A clogged oil filter, combined with a closed bypass valve, prevents the compressor oil from reaching the engine head. This causes the main unit to heat up rapidly due to lack of oil. Solution: Clean the oil filter regularly.
4. Faulty Thermostatic Valve
The thermostatic valve controls the flow of lubricating oil to ensure the appropriate oil temperature before entering the engine head. If the thermostatic valve is damaged, uncooled lubricating oil will enter the main unit, causing it to overheat. Solution: Regularly checking the thermostatic valve can effectively prevent overheating.
5. Using inferior lubricant or exceeding the service life
Inferior lubricant has poor temperature resistance and is prone to coking, which can affect the rotor and bearings in the handpiece and cause the handpiece to overheat. Prolonged use of genuine lubricant may cause emulsification or coking. Solution: It is recommended to use genuine lubricant and replace it regularly.
