Description

Technical Field

[0001] The present invention relates to the technical field of compressors, and in particular to an oil circuit structure and a compressor having the same. Background Art

[0002] Scroll compressors have the advantages of simple structure, small size, light weight, low noise, high mechanical efficiency and smooth operation. With the development of technology, compressors are developing towards high speed, which places higher requirements on the oil circuit lubrication of the compressor.

[0003] In a scroll compressor, the role of lubricating oil is to cool and lubricate the friction parts of the motor and bearings, reduce friction power consumption, and improve the operating efficiency of the compressor. During the operation of the compressor, some lubricating oil will enter the compression chamber along with the refrigerant, and while cooling and lubricating the compression chamber, it will fill the tiny gap between the movable scroll and the static scroll, seal the compression chamber radially and axially, inhibit refrigerant leakage, and ensure the energy efficiency and reliability of the compressor during operation. In order to ensure a sufficient supply of lubricating oil inside the compressor, an oil pump structure is usually set under the rotating shaft of the compressor to extract the lubricating oil.

[0004] However, as the compressor operating frequency increases, the rotating shaft speed increases, and the amount of lubricating oil transported to the compression mechanism also increases. Excessive lubricating oil entering the compression chamber not only affects the operating efficiency of the compressor, but also causes a large amount of lubricating oil to enter the refrigeration system along with the refrigerant after being discharged from the compression mechanism, resulting in a decrease in the amount of oil inside the compressor and insufficient lubrication between the mating parts, which can easily lead to an increase in the temperature of the mating parts such as the bearings, increased friction, and even burning and wear, which will seriously affect the performance and reliability of the compressor.

[0005] In the current compressor structure, an oil hole is usually drilled inside the upper bracket, and a throttling screw is installed in the hole to control the oil flow entering the compression chamber; however, this method of controlling the oil volume requires opening a complex oil passage in the upper bracket, which makes the processing of the upper bracket more difficult, thereby increasing the difficulty of processing the compressor.
