Compressor with built-in oil separator

Abstract

The invention discloses a compressor with a built-in oil separator. The compressor comprises a compressor body; a shell provided with a front shell part, wherein the front shell part is provided with an exhaust port, and an exhaust cavity is formed between the front shell part and a static vortex; an oil separator shell arranged on the front shell part, wherein an oil separator channel is formed between the oil separator shell and the front shell part, the oil separator channel communicates with the exhaust port, the oil separator channel is provided with a stop part, an oil separator inlet is formed in the oil separator shell, and the oil separator inlet communicates with the oil separator channel and the exhaust cavity; and an oil separator core rod which is arranged in the oil separator channel, wherein an exhaust channel is arranged in the oil separator core rod, the exhaust channel communicates with the oil separator channel and the exhaust port, a spiral channel is formed between the oil separator core rod and the oil separator channel, the spiral channel communicates with the oil separator channel, the spiral channel communicates with the oil separator inlet, and a contact part is arranged on the oil separator core rod. Through the application of the compressor, the oil storage capacity of the compressor is improved, impurities are prevented from being generated in the installation process, and the safety and reliability of the compressor are further improved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor with built-in oil. Background technique [0002] With the further increase in the output of new energy vehicles, users have higher requirements for the performance of new energy vehicles. At present, the air conditioning and refrigeration systems of more new energy vehicles use scroll compressors. However, in order to ensure The body weight and internal installation space of new energy vehicles are designed reasonably, which often place higher requirements on the design of vehicle scroll compressors, which will inevitably make the structure of the compressor more compact and smaller, but this also causes the compressor itself The oil storage space for storing lubricating oil is relatively limited. At the same time, in order to better meet the market demand, the maximum speed of the scroll compressor is constantly increasing, and the high-speed operation of the c...

[0002] With the further increase in the output of new energy vehicles, users have higher requirements for the performance of new energy vehicles. At present, the air conditioning and refrigeration systems of more new energy vehicles use scroll compressors. However, in order to ensure The body weight and internal installation space of new energy vehicles are designed reasonably, which often place higher requirements on the design of vehicle scroll compressors, which will inevitably make the structure of the compressor more compact and smaller, but this also causes the compressor itself The oil storage space for storing lubricating oil is relatively limited

At the same time, in order to better meet the market demand, the maximum speed of the scroll compressor is constantly increasing, and the high-speed operation of the compressor can easily cause a large amount of lubricating oil to be discharged into the system along with the refrigerant, thus causing the reliability of the compressor. performance issues and system inefficiencies
