Abstract

The invention provides a volute tooth shaped line, a volute plate structure and a compressor comprising same. The volute tooth shaped line is characterized in that a main bus comprises a central involute, a transition involute and an outside involute which are continuously arranged from center to the outside, wherein the central involute is a base circle involute; the transition involute is a variable-diameter base circle involute; the outside involute is a base circle involute; and the radius of a base circle is the maximum radius of the base circle of the variable-diameter base circle involute. According to the volute tooth shaped line, the variable-frequency base circle involute is introduced, so that the wall thickness of the volute plate is increased, and as a result, the radial gas leaking is reduced, and the volute compression ratio is increased.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a scroll profile, a scroll structure and a compressor including the scroll structure. Background technique [0002] The scroll compressor was first born in 1905 and was invented by French engineer Leon Creux, but due to the limitations of processing technology at that time, it did not receive in-depth research and development. It was not until the 1970s that the aggravation of the energy crisis and the development of numerical control machining technology made the scroll compressor develop again. [0003] Scroll compressor applications mainly include air conditioners, superchargers, liquid pumps, etc. Scroll compressors can meet various needs by compressing low-pressure gas into high-pressure gas (ie, compression ratio characteristics). The compression ratio of the scroll compressor is closely related to the profile type, and different scroll profiles form different compres...
