Problems solved by technology

However, this method of lubrication and sealing has defects. Because when the compressor is working, the baffle and the rolling ring are always in motion, and the surface often cannot form an oil film. There will be direct leakage of gas and boundary friction between friction parts. Therefore, it is necessary to improve and overcome the problems existing in the lubrication and sealing of the compressor cylinder

Abstract

The invention provides a lubricating and sealing structure for a cylinder of a rotary compressor, which comprises the cylinder, wherein the front end of the cylinder is provided with a baffle plate groove, a baffle plate which divides a working chamber of the cylinder into an air suction cavity and an air discharge cavity is arranged in the baffle plate groove, and a rolling ring is positioned in the working chamber of the cylinder. The improvements are that the outer surface of the baffle plate is plated with a solid lubricant layer, the outer surface of the rolling ring is plated with a solid lubricant layer; and by means of the action of lubricating and buffering external pressure of a solid lubricant, the baffle plate and the rolling ring avoid the problem of boundary friction in movements through self adjustment so as to achieve the minimum sealing clearance for the cylinder of the compressor, improve the volume efficiency, and ensure the working efficiency and the reliability of the compressor.

Description

technical field [0001] The invention relates to a compressor, in particular to a lubricating and sealing structure of a cylinder of a rotary compressor capable of ensuring the smallest sealing gap and better lubricating effect and effectively improving the volumetric efficiency of the compressor. Background technique [0002] The air conditioner is a device that cools and warms the air in the indoor space after exchanging heat between the refrigerant circulating through the compressor, condenser, expansion device, and evaporator and the air passing through the evaporator. The structure of the air conditioner includes an outdoor unit composed of a compressor, a condenser, and an expansion device, and an indoor unit composed of a fan and an evaporator. The outdoor unit and the indoor unit are connected to each other through refrigerant piping. [0003] Generally, compressors are classified into rotary compressors, reciprocating compressors, scroll compressors, and the like acc...
