Why does the temperature of the permanent magnet variable frequency air compressor become higher?

Reasons for the high temperature of the permanent magnet variable frequency air compressor:

1. Lack of lubricating oil. The lubricating oil of the permanent magnet variable frequency screw air compressor not only has the function of lubrication and sealing, but also can cool the unit, so it is also called “coolant”. (Solution: add air compressor oil, if the temperature is too high due to deterioration of lubricating oil, replace it.)

2. The cooler is blocked. The cooler is also commonly known as a “radiator”. The lubricating oil circulating in the permanent magnet variable frequency screw air compressor needs to be cooled by the cooler before it can flow back to the main air compressor. When the cooler is dirty and clogged, the lubricating oil of the air compressor cannot be cooled, so the temperature will remain high after recovery. (Solution: Clean the cooler with dry compressed air. If you can’t clean it, take it out and clean it.)

3. The oil filter is clogged. The function of the oil filter is to filter the impurities in the lubricating oil and protect the main engine of the permanent magnet variable frequency air compressor. If it is not replaced for a long time, or the operating environment is harsh, the oil filter is clogged, the oil flow inside the air compressor is small, and the main engine cannot get enough lubricating oil to cool it in time, resulting in high temperature. (Solution: replace the oil filter, or do oil circuit maintenance.)

4. The temperature control valve is faulty. The function of the temperature control valve is to control the oil injection temperature of the main engine of the oil injection permanent magnet variable frequency air compressor; it uses a temperature control element to control the opening of the element valve core according to the oil temperature, so as to control the amount of oil passing through the oil cooler, so that After the hot and cold oil is mixed, it goes to the main engine, so as to control the temperature of fuel injection and exhaust gas! (Solution: Replace the temperature control valve.)

5. The main controller of the permanent magnet variable frequency screw air compressor is faulty.

6. The temperature sensor is faulty.
