PRODUCT PROFILE
Refrigerating oil is a special lubricating oil for compression refrigeration compressor, in addition to ensure the lubrication of the relevant equipment parts in refrigeration compressor, reduce friction and wear, but also assume the role of cooling, the refrigeration process of a lot of heat is constantly carried out, so that the mechanical equipment is kept at a low temperature, so as to improve the efficiency of the refrigerator and ensure reliable operation.
PRODUCT CHARACTIESTICS
1.good fluidity at lower temperatures;
2.it has strong thermal stability;
3.strong miscibility, lubricity and insulation;
4.the pour point and flocculation point are low.
MAIN FUNCTION
(1) lubricate the friction surface so that the friction surface is completely separated by the oil film, thereby reducing friction work, friction heat and wear
(2) The flow of the refrigerant oil takes away the friction heat, so that the temperature of the friction parts is kept within the allowable range
(3) Fill the sealing part with oil to ensure sealing performance and prevent leakage of refrigerant
(4) The movement of oil takes away the abrasive dust generated by metal friction, and plays the role of cleaning the friction surface
(5) Provide hydraulic power for the unloading mechanism
