Compressor oil is generally used in compressors to cool the compressor by removing the heat generated by adiabatic compression, to lubricate bearings and other parts, and to act as a seal to prevent gas leakage at sliding parts. ing. Gases to be compressed include air, oxygen, carbon dioxide, nitrogen, hydrogen, various hydrocarbon gases, chlorine gas, and ammonia gas, but among these, compressor oil is the one that is the most common and has the most severe conditions for compressor oil. It is an air compressor.

Particularly in oil-cooled rotary air compressors, compression condenses water vapor in the air to produce moisture, which forms an emulsion with compressor oil. Moisture dispersed in compressor oil has negative effects such as deterioration of lubricity and accelerated deterioration of compressor oil, but the biggest problem for compressor operation is the strong emulsion sludge produced from compressor oil and moisture. is attached to the surface of the cooling water pipe in the oil cooler.

Moreover, the emulsion sludge that is generated inside the oil cooler is not just a plain water emulsion, but is a strong one that also includes solid matter generated by oxidation of oil and additives, wear particles from various parts, and dust.

As a result of such strong emulsion sludge adhering to the surface of the cooling water pipe, the heat transfer from the C1 compressor oil to the cold water is inhibited, causing a rise in the temperature of the compressor oil, and eventually causing the oil temperature detection relay to operate. Causes compressor shutdown.
