Freezer in the oil of choice there are still many tips, according to the choice of different types of machine oil are not the same. 1, according to the type of compression of different options lubricants; freezer compressor has three 636 Mobil synthetic gear oil, piston, screw, centrifugal. Piston and screw-type lubricant and refrigerant in direct contact, to consider the interaction between them, and the only centrifugal oil used to lubricate the rotor bearing, so you can choose N32 or N46 turbine oil based on the size of the load and speed . 2, the selection depending on the type of the refrigerant oil, which is bound to take into account the interaction between the lubricant and the refrigerant. For example, a class of Freon refrigerant can be dissolved in mineral oil, so the oil viscosity choice than using insoluble refrigerant to a high level SHC632 Mobil synthetic gear oil, but also to ensure that the role of the lubrication oil diluted. Check the mixed refrigerant oil is precipitated wax crystals to clog the cooling system, which is the quality indicators we have always said refrigerating machine oil flocculation point. 3, in addition to selection based on the type of refrigerant lubricants, they can also chosen according to the evaporation temperature of the refrigerant oil, generally, according to the level select the corresponding evaporation temperature of the refrigerant oil pour point, while using ammonia as the refrigerant in refrigeration machine, used lubricating oil pour point should be below the evaporation temperature. Freon as a refrigerant with synthetic gear oil, lubricating oil pour point may be slightly higher than the evaporation temperature. 4, the working conditions of the freezer selection of different lubricants are different, large and medium-sized multi-cylinder, high-speed (average piston speed of 3m / s or more), the load should be used in a large freezer large viscosity VG46 or VG68 or VG100 frozen oil. Exhaust gas temperature at high load of about 145 ℃ freezing refrigerating machine oil VG68 or VG100. Small, miniature or low (not higher than the average piston speed 2m / s) of the freezer refrigeration oil VG32 or VG22 available. Mobil Rarus SHC1024/SHC1025/SHC1026 synthetic air compressor oil;. Mobil Rarus SHC1024, 1025 Senior Mobil synthetic gear oil, Mobil Rarus SHC1020 1026 series is a synthetic hydrocarbon oil-based compressor oils made applicable to all kinds of sliding vane and screw air compressors. their superior heat resistance and high temperature oxidation stability is particularly suitable for injection cooled screw compressor, this product is particularly suitable for mineral oil products incompetence of poor working conditions, such as must withstand high temperature, high pressure oil or asked to take a long cycle applications.
