Air compressor overheating protection is to protect equipment and improve work efficiency. Here are some possible causes of air compressor overheating and related solutions.

1. Air filter is clogged: The air filter is an important part of protecting the air compressor. When the filter is clogged, it will cause poor air flow, increase the compressor workload, and cause the compressor to overheat. The solution is to clean and replace the filter regularly to ensure smooth air flow.

2. Cooler is clogged: The cooler is a key device for reducing the temperature of compressed air. When the surface of the cooler is covered with dust and impurities, the heat dissipation effect will be weakened, causing the compressor to overheat. The solution is to regularly clean the surface of the cooler to maintain good heat dissipation.

3. Oil problem: Some air compressors require lubricating oil to ensure normal operation. When the lubricating oil quality is poor or the oil is insufficient, it will cause increased friction in the air compressor, causing overheating. The solution is to regularly check and replace the lubricating oil to ensure that the oil quality and oil quantity meet the requirements.

4. Excessive running time: Continuous long-term high-load operation will cause the air compressor to overheat. The solution is to reasonably arrange the time when using the air compressor to avoid continuous long-term high-load operation.

5. Motor problem: The motor is the power source of the air compressor. When the motor fails, it may cause the air compressor to overheat. The solution is to regularly inspect and maintain the motor to ensure it is operating properly.

6. Environmental issues: High temperature and humid environments will affect the heat dissipation of the air compressor, leading to overheating. The solution is to provide proper ventilation and keep the ambient temperature and humidity around the air compressor within normal limits.

7. Overload problem: When the air compressor operates beyond the rated load, it will cause overheating. The solution is to avoid long-term overload operation of the air compressor and reasonably arrange the usage load.

In short, air compressor overheating protection is to protect equipment and improve work efficiency. Regular cleaning and maintenance of key equipment such as air filters, coolers and motors, inspection and maintenance of lubricating oil quality and oil volume, reasonable arrangement of usage load and operating time, and provision of appropriate environmental conditions are all ways to prevent and solve air compressor overheating.
