Scroll type linear tooth head structure of scroll compressor and correcting method thereof

Abstract

The invention provides a scroll type linear tooth head structure of a scroll compressor. The scroll type linear tooth head structure of the scroll compressor is characterized in that gas is exhaustedthrough static scroll plates and a movable scroll plate; when a gas suction chamber is closed, a first clearance is formed between a first center head part section and a second center inner circular arc section, a second clearance is formed between a second center head part section and a first center inner circular arc section, and scroll teeth of the static scroll plates between the gas suction chamber and an intermediate pressure chamber are engaged with scroll teeth of the movable scroll plate; the static scroll plates and the movable scroll plate are capable of sucking air and compressing;and when the gas suction chamber is gradually opened, the scroll teeth of the static scroll plates between the gas suction chamber, the intermediate pressure chamber and the gas exhausting chamber are engaged with the scroll teeth of the movable scroll plate. The invention also provides a correcting method of the scroll type linear tooth head structure of the scroll compressor. According to the scroll type linear tooth head structure of the scroll compressor and the correcting method, the tooth head parts are engaged through gradual clearances, so that the pressure of a compressing chamber and the pressure of a gas exhausting hole are close to each other or equal to each other while the compressing chamber communicates with the gas exhausting hole; the compressing process can be subjectedto smooth transition, the mechanical noise and electromagnetic noise caused by suddenly changed pressure can be reduced, and thus the energy efficiency ratio can be increased.

Description

technical field [0001] The invention relates to the field of scroll compressors, in particular to a scroll profile tooth head structure of a scroll compressor and a correction method thereof. Background technique [0002] The current electric air conditioner compressor for passenger cars is a moving scroll with the same scroll shape parameters, a phase difference of 180°, and a distance R between the center of the base circle (the scroll structure that moves in translation with the rotation of the main shaft in the scroll compressor structure) Assembled with the static scroll (a fixed structure that works in conjunction with the movable scroll), several pairs of closed crescent-shaped volume cavities are formed; as the movable scroll revolves around the central axis of the main shaft with a rotation radius R to perform a rotational-translational motion without rotation, these The closed crescent-shaped volume cavity becomes smaller correspondingly, thereby realizing the suct...

AI Technical Summary

Problems solved by technology

In the process of gradually opening the suction chamber in this patent, there is a gap between the scroll teeth of the fixed scroll and the scroll teeth of the movable scroll between the intermediate pressure chamber and the suction chamber, so that there will be a serious problem during the operation of the compressor. Leakage, and the leakage is external leakage (intermediate pressure chamber and suction chamber through, and the maximum gap is 0.2mm), which will cause a significant increase in energy consumption of the compressor, which in turn will cause a significant decrease in the energy efficiency ratio of the system, which violates the design and development original intention

Moreover, in the correction method, the patent only mentions the preset value of indentation in the molded line, and does not specify a specific method to achieve this preset value. It only proposes a concept, and the concept mentioned increases zero to a large extent. The difficulty of component detection increases the difficulty of making parts, which violates the original intention of design and development (the original intention of the invention is to reduce the difficulty of making parts)
