Zhuolijia Tong refrigeration oil refrigeration compressor parts lubricating oil has a suitable flash point

The main performance of refrigeration oil is excellent low-temperature performance: strict pour point and U-shaped tube flowability indicators can ensure that the oil will not condense in the low-temperature components of the refrigeration unit such as the evaporator, meeting the free conversion requirements of the refrigeration unit from the high-temperature working area to the low-temperature working area. Excellent oxidation stability: DRA series refrigeration oil is matched with an appropriate amount of antioxidant additives, providing better resistance. Oxidative properties effectively extend the oil change period of the refrigeration unit. Suitable refining depth: Ensure that the oil does not accumulate carbon in high-temperature areas such as valves, resulting in pipeline blockage. Good Cleanliness: The oil is transparent and pure, which has a cleaning effect on the working parts and can effectively prevent the occurrence of impurities particles rubbing against the surface of the bearing. DRA/B series refrigeration oil also has good chemical stability: it ensures the stability of the oil when coexisting with Freon refrigerants, greatly reducing the occurrence of refrigerant decomposition, compression component corrosion, and other phenomena.

The main reasons for the deterioration of refrigeration oil

　　Mixing of moisture: Due to the infiltration of air into the refrigeration system, the moisture in the air comes into contact with the refrigeration oil and mixes in; When the refrigerant contains a high amount of water, it can also cause moisture to mix into the refrigeration oil. When water is mixed into the refrigeration oil, the viscosity decreases, causing corrosion to the metal. In Freon refrigeration systems, it can also cause the phenomenon of "ice blockage";

　　Oxidation: During the use of refrigeration oil, when the exhaust temperature of the compressor is high, it may cause oxidation deterioration, especially for refrigeration oil with poor chemical stability, which is more prone to deterioration. After a period of time, residue will form in the refrigeration oil, causing lubrication damage to bearings and other areas. Mixing organic fillers, mechanical impurities, etc. into refrigeration oil can also accelerate its aging or oxidation;

　　Mixing of refrigeration oil: When several different grades of refrigeration oil are mixed, it can cause a decrease in the viscosity of the refrigeration oil, and even damage the formation of the oil film, causing damage to the shaft; If two types of refrigeration oil contain antioxidant additives with different properties, mixing them together may cause chemical changes, form precipitates, and affect the lubrication of the compressor. Therefore, attention should be paid when using them.

　　There are impurities in the refrigeration oil.
