AI Technical Summary

Technical Problem

The existing scroll compressors have high machining difficulty in positioning the stationary scroll plate, requiring precision tooling and exhibiting assembly errors, which affect sealing performance and operational stability.

Method used

A compression positioning assembly is adopted, including a main frame, a stationary scroll structure, a moving scroll structure, and a limiting ring. By setting first and second mating parts and positioning structures on the main frame, the circumferential, axial, and radial movement of the stationary scroll is restricted, ensuring the stable positioning of the stationary scroll.

Benefits of technology

It simplifies the assembly process of scroll compressors, improves the installation accuracy and operational stability of the stationary scroll plate, enhances sealing performance and energy efficiency, and reduces processing difficulty and cost.
