Abstract

The invention discloses a reciprocating compressor oil scraping structure. The reciprocating compressor oil scraping structure comprises a connecting cylinder, an oil scraping ring assembly is arranged on the connecting cylinder in a penetrating manner, the oil scraping ring assembly comprises an oil scraping flange, an oil scraping box, oil scraping ring pairs and springs, the oil scraping flange is fixedly connected with the oil scraping box through bolts, the two oil scraping ring pairs are arranged in the oil scraping box in a penetrating manner, and each oil scraping ring pair comprises two oil scraping rings, wherein the two oil scraping rings are the first oil scraping ring and the second oil scraping ring respectively, each oil scraping ring is composed of a three-section structure, oil scraping ring gaps are formed between sections, the oil scraping ring gaps in the first oil scraping ring and the oil scraping ring gaps in the second oil scraping ring are placed in a staggered manner, the circumferential positions of the oil scraping rings are fixed through positioning pins, and the springs are embedded into the outer sides of the oil scraping rings; and an oil baffle plate is arranged at one side of the connecting cylinder. The reciprocating compressor oil scraping structure can solve the problems that an existing oil scraping structure is incomplete in oil scraping, low in oil scraping efficiency, unsmooth in oil return and inconstant in oil scraping effect.

Description

technical field [0001] The invention relates to an oil scraping structure, in particular to an oil scraping structure of a reciprocating compressor, which belongs to the technical field of compressor manufacturing. Background technique [0002] In reciprocating compressors, oil is usually present in the case to lubricate the moving parts of the compressor. Lubricating oil is also carried away by the piston rod to the cylinder parts during the movement of the mechanism. In order to prevent this from happening, a set of oil scraping structure is often used between the casing and the cylinder, the purpose of which is to scrape off the lubricating oil on the piston rod and prevent the lubricating oil from entering the cylinder through the piston rod. [0003] The Chinese utility model patent with the application number CN201520012751.5 discloses a reciprocating compressor oil scraper. The second-stage oil scraping device, the third-stage oil scraping device, the sealing device...
