Compressor core supporting structure

Abstract

The invention discloses a compressor core supporting structure which comprises a gasket, a damping part, an upper lining, a spring, a lower lining and a convex pin. The convex pin is sleeved with thelower lining, the lower lining is sleeved with the lower portion of the spring, the upper lining is sleeved with the upper end of the spring, the upper lining is sleeved with the damping part, and thedamping part is located between the gasket and the spring. By means of the supporting structure, base frequency vibration of a compressor in the vertical direction can be obviously reduced, base frequency vibration of the compressor in the two horizontal directions tends to be approximate, and therefore vibration and noise of a refrigerator are reduced. The damping part is located on the upper portion of the spring, and will not be soaked in freezing oil for a long time, and the service life can be prolonged. The compressor core supporting structure is simple in structure, convenient to implement and install and low in cost.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a support device used between an internal core and a housing of a refrigeration compressor. Background technique [0002] Refrigeration compressors are installed on domestic or commercial refrigerators or freezers. When the refrigeration compressor is working, the refrigerant enters the refrigeration system through the suction pipe, suction muffler, cylinder, exhaust chamber, inner exhaust pipe, and exhaust pipe. During this process, the piston will reciprocate, thereby causing the movement to vibrate, and the vibration is transmitted to the casing along the support structure of the movement and the inner row pipe. The existing supporting structure of the compressor core generally includes a gasket, an upper bush, a spring, a lower bush and a convex nail, and the vibration of the core along the supporting structure is mainly damped by the spring. Usually, technicians will r...

AI Technical Summary

Problems solved by technology

However, this damping structure is completely wrapped and extruded by the lower bushing and the convex nails, and there is little room for physical deformation of the damping structure, so the shock isolation effect is also weakened

And the damping structure in the lower bushing is located in the refrigerated oil for a long time, which is easy to age and lose the shock isolation effect

The PCT patent application with the publication number CN100465435C discloses a suspension device for compressors. A damping structure is also arranged between the lower bush and the protruding nails. Because the damping structure is located in the refrigerating oil for a long time, it is easy to age and loses insulation. shock effect
