Compressor oil blocking assembly, rotor assembly, compressor and air conditioner system

Abstract

The invention discloses a compressor oil blocking assembly, a rotor assembly, a compressor and an air conditioner system. The compressor oil blocking assembly comprises an oil blocking cap and an oil blocking base which is used for being fixedly connected with the oil blocking cap and can be arranged outside the connecting sleeve in a sleeving manner. A connecting sleeve used for being matched with the tail portion of a bent axle is arranged at the bottom end of the oil blocking cap. A first preset distance is formed between the bottom face of the oil blocking cap and the top face of the oil blocking base, and a second preset distance is formed between the bottom face of the oil blocking base and the bottom end face of the connecting sleeve. The compressor oil blocking assembly is provided with a double-layer oil blocking structure of the oil blocking cap and the oil blocking base, two-time oil blocking is achieved, the oil blocking effect is effectively improved, the oil output rate of the compressor, especially a large-displacement double-cylinder compressor is reduced. According to the air conditioner system applying the compressor oil blocking assembly, the heat exchange efficiency of the air conditioner system is improved, and the performance of the whole air conditioner system is improved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor oil retaining assembly, a rotor assembly, a compressor and an air-conditioning system. Background technique [0002] When the compressor is running, especially when it is running at high frequency, the refrigerating oil inside the compressor will be discharged with the exhaust airflow and enter the system, which will make it difficult to return the oil from the compressor, resulting in a shortage of refrigerating oil in the compressor, causing compression The machine parts are poorly lubricated and the wear is intensified, which cannot guarantee the reliability of the compressor operation. In addition, in the air-conditioning system, if the refrigerated oil enters the air-conditioning system, the heat exchange efficiency of the air-conditioning system is low, resulting in low performance of the air-conditioning system. [0003] Therefore, it is necessary to arra...

AI Technical Summary

Problems solved by technology

The above-mentioned oil retaining assembly has only one layer of oil retaining structure, that is, one-time oil retaining, resulting in poor oil retaining effect of the oil retaining assembly, which reduces the oil discharge rate of the compressor, especially the large-displacement two-cylinder compressor

[0004] In addition, the interference fit between the oil deflector cap and the tail of the crankshaft leads to low assembly reliability and affects assembly accuracy

[0005] In addition, the oil deflecting cap is located on the side of the balance weight away from the rotor, so during the rotor magnetization process, only the rotor is used for magnetization and positioning, resulting in poor positioning effect
