AI Technical Summary

Technical Problem

The existing scroll compressor has a difficult oil supply channel to process, many size restrictions, and the oil supply is affected by the rotation speed, resulting in insufficient or excessive lubrication, which affects the wear of the contact surface between the stationary scroll and the moving scroll.

Method used

The system employs an oil guide structure, including an oil inlet section, an oil outlet section, and an oil guide pipe. Lubricating oil flows into the working chamber from the recess of the main bearing housing through the oil guide pipe. The oil guide pipe is located inside the scroll compressor, and the pressure difference and sealing structure ensure the supply of lubricating oil, avoiding direct oil supply from the drive shaft.

Benefits of technology

It simplifies processing and assembly, reduces manufacturing costs, ensures that an appropriate amount of lubricating oil is effectively supplied to the working chamber, reduces wear, and avoids uneven oil supply caused by easy damage to the external structure and the influence of rotation speed.
