    1 Before the replacement, it is necessary to check the cause of damage to the original refrigeration compressor and replace the defective parts Because the damage of other parts will directly lead to the damage of refrigeration compressor, remember! 2 After the original damaged refrigeration compressor is removed, the system must be purged with nitrogen before it can be connected to the new refrigeration compressor system 3 During the welding operation, in order to avoid the formation of oxide film on the inner wall of the copper tube, it is recommended to inject nitrogen, and the time for nitrogen to enter shall be sufficient 4 When replacing the refrigeration compressor or other parts, it is forbidden to use the refrigeration compressor as a vacuum pump to empty the air in the pipeline of the external unit, otherwise the refrigeration compressor will be burned, and the vacuum pump must be used for vacuumizing 5 When replacing the refrigeration compressor, the refrigeration oil conforming to the nature of the refrigeration compressor must be added, and the amount of the refrigeration oil should be appropriate Generally speaking, the new original compressor has the refrigeration oil 6 When replacing the refrigeration compressor, the drying filter must be replaced in time Because the desiccant in the drying filter is saturated, the water filtering function is lost 7 The refrigeration oil in the original system must be cleaned, because the new pump has been injected with enough production refrigeration oil, and the refrigeration oil of different brands cannot be mixed, otherwise it will deteriorate and cause poor lubrication, resulting in cylinder pulling, yellowing and burning of the refrigeration compressor 8 When replacing the refrigeration compressor, pay attention to prevent the excessive refrigerant oil in the system, otherwise the heat exchange effect of the system will be reduced, so that the system pressure will be on the high side, and the system and the refrigeration compressor will be damaged 9 Don't fill the refrigerant too fast, otherwise it will produce liquid hammer, which will cause the valve plate to break, resulting in the internal noise and pressure loss of the refrigeration compressor 10 After installation, check whether the compressor works normally, such as: suction pressure / temperature, exhaust pressure / temperature, oil pressure differential pressure and other system parameters If the parameter exceeds the normal value, it is necessary to find out the cause of the system parameter abnormality.
