What to do if the refrigeration compressor is damaged

What to do if the refrigeration compressor is damaged After the refrigeration compressor in the refrigeration system is damaged, the new compressor cannot be replaced directly because there may be some incentives for the refrigeration compressor to be damaged. The new compressor must be replaced after all the incentives are eliminated. 1. After the original damaged refrigeration compressor is removed, the system must be blown with nitrogen to remove the new refrigeration compressor system. 　　 2. During the welding operation, in order not to form an oxide film on the inner wall of the copper tube, nitrogen must be passed in, and the time for the nitrogen to pass must be sufficient. 　　 3. It is forbidden to use the compressor as a vacuum pump to evacuate the air in the pipeline of the external machine when replacing the refrigeration compressor or other parts, otherwise the compressor will be burned, and the vacuum pump must be used to evacuate. 　　 4. When replacing the refrigeration compressor, it is necessary to add an appropriate amount of refrigeration oil that matches the compressor. 　　 5. Before replacing, you must check the cause of the damage to the original compressor and replace the defective parts. Because the damage of other components will also directly cause damage to the compressor. 　　 6. When replacing the refrigeration compressor, the filter drier must be replaced in time. Because the desiccant in the desiccant 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 a sufficient amount of refrigeration oil, and different brands of refrigeration oil cannot be mixed, otherwise it will deteriorate and cause poor lubrication, causing the refrigeration compressor to pull the cylinder and turn yellow. , Burnt. 　　 8. When replacing the refrigerating compressor, pay attention to prevent the excessive amount of freezing oil in the system, otherwise it will cause the heat exchange effect of the system to be reduced, thereby making the system pressure higher and damaging the system and compressor. 　　 9. Don't fill the refrigerant too fast, otherwise it will produce liquid blow, which will cause the valve slice to break, resulting in pressure loss in the compressor. 　　10. After the installation, check whether the radiator is working properly. If the system pressure exceeds the normal pressure (13-15kg), it will cause the clutch to slip, the bearing, the coil will burn out, or the compressor will be damaged.
