Selection requirements of refrigeration compressor oil for chiller

The refrigeration compressor is equivalent to the heart of the chiller. Of course, in addition to ensuring its own quality assurance, its compressor oil should also be paid attention to.

1. Has good oxidation stability

To ensure the oxidation stability of the compressor oil in the chiller and prevent the formation of sludge by oxidation (the exhaust temperature of the compressor is generally 120 ° C-200 ° C, which may reach 300 ° C, and the compressor oil is easily oxidized to generate sludge at high temperature).

2. Have a suitable viscosity

Appropriate viscosity of refrigeration compressor oil can make the compressor play a good lubrication, cooling and sealing role at working temperature and pressure, so as to ensure the normal operation of the chiller compressor.

3. The tendency of carbon deposition is better

If there is carbon accumulation in the exhaust system, the exhaust valve will be closed tightly, and the cooling effect will be poor. The temperature of the exhaust gas will increase, and the refrigeration compressor will easily fail. Therefore, the carbon deposition tendency of the compressor needs to be better.

4. Good emulsification resistance, corrosion resistance and foam resistance

It is easy to mix condensate and air in the compressor oil of the chiller, which will emulsify and deteriorate the oil, increase the corrosion and wear of the machine parts, and oxidize the oil. Therefore, it is required to have good emulsification resistance, corrosion resistance and oxidation resistance.

5. Replacing the compressor oil of the chiller requires professional operation, and it should not be changed without permission to avoid unnecessary
