What is the reason for high exhaust temperature of variable frequency air compressor? Air compressor cooling failure

What is the reason for high exhaust temperature of variable frequency air compressor?

The high exhaust temperature of screw air compressor is generally caused by the high temperature of oil cooler and water cooler, and may also be caused by sensor failure. After using the variable frequency air compressor for a period of time, the exhaust temperature may be high. What is the reason? Today, demang air compressor will introduce this in detail.

Fault phenomenon: the exhaust temperature of the unit is high (over 100 ℃), which may be caused by the following reasons:

1. Temperature control system failure.

2. The oil cut-off valve is stuck due to fault.

3. Cooling fan failure.

4. The ambient temperature is too high and the exhaust is not smooth.

5. The lubricating oil cooling level of the unit is too low (the upper and lower limits of the normal position, but not more than half).

6. How to judge whether the oil cooler is dirty if the oil cooler is dirty? It mainly depends on the temperature difference between the inlet and outlet. The normal temperature difference is 20 ~ 30 ℃. If the external dust is blocked, the radiator only needs to be blown clean with compressed air. If the internal organs of the radiator need special cleaning solvents (such as acetone). If the radiator is seriously blocked, it needs to be cleaned with a clean water pump.

7. The oil filter element is blocked.

These seven reasons may lead to high exhaust temperature of variable frequency air compressor. If you need more information, you can check the corresponding section.
