What is the reason for the high oil temperature of air compressor?

The high oil temperature of air compressor may have the following reasons:

1. The cooler is inefficient.

2. Lubricating oil aging failure, manifested as poor oil quality or excessive impurities.

3. The oil temperature sensor is out of order.

4. The coordination of moving parts is poor.

5. Through throttle adjustment, the oil temperature may increase due to the decrease of intake pressure and the increase of power consumption.

6. High ambient temperature leads to high lubricating oil temperature.

7. The oil return circuit is not smooth and the oil filter is blocked.

8. Insufficient oil supply.

9. There is too much dirt or blockage in the water pipe of the oil cooler.
