Description

Technical Field

[0001] The present application relates to the technical field of compressors, and in particular to a wear-resistant structure of a moving plate and a scroll compressor. Background Art

[0002] During the use of the scroll compressor, the moving plate, wear-resistant plate and support seat are often fitted together. Due to the high-speed operation of the moving plate, the direct contact between the moving plate and the wear-resistant plate will cause the damage to the moving plate to be aggravated. Although there is lubricating oil between the moving plate and the wear-resistant plate, the high pressure generated during the movement will destroy the oil layer. The initial oil layer is broken, and the new oil has no time to be replenished, resulting in the oil film becoming broken or even disappearing, which will greatly aggravate the loss of the moving plate and reduce the power and service life of the compressor.
