Resumen
This study describes the remanufacturing process scheme and key technologies of waste compressors. Firstly, the technical characteristics of compressors for home appliances such as refrigerators and air conditioners are summarised. Then, the remanufacturing process scheme is proposed with the waste refrigerator compressor as the research object. The purpose or requirements of key processes such as separation, disassembling, cleaning, detecting, remanufacturing and reassembling are also elaborated. Moreover, the corresponding remanufacturing technology or method is proposed to satisfy the structural, quality requirement, economy and environmental friendliness of products and components. The cleaning technology of the compressor motor stator and the remanufacturing technology of crankshaft is highlighted. In accordance with the structural and quality requirement of the motor stator, the cleaning method of the motor stator is proposed, and the environmental friendliness, economy and safety of several cleaning agents are analysed. The scheme of crankshaft remanufacturing is proposed on the basis of the failure form of the crankshaft and the quality requirement of remanufacturing. Moreover, the process parameters are described.
