AI Technical Summary

Technical Problem

The existing electric compressors are inefficient in lubricating oil circulation filtration flow, with less oil return, complex processing and assembly of oil return holes, cumbersome flow detection of oil return channels, and the back pressure structure is prone to wear and fail. The traditional filter and oil return channels are easily blocked, resulting in a gradual reduction in lubrication effect.

Method used

An electric compressor oil return seal gasket is designed, including seal gasket, curve groove, oil outlet, filter groove and oil return port. The lubricating oil filters out large particles of impurities through the filter tank and return oil port, enters the curve tank and flows into the cavity through the oil outlet port, and lubricates the bearings, moving discs and wear-resistant gaskets using a stirring mechanism.

Benefits of technology

The effective oil return and filtration of lubricant oil is achieved, which ensures efficient circulation of lubricant oil, avoids clogging of oil return passages and wear of back pressure structures, and significantly improves the service life of the electric compressor and the consistency of product performance.
