Problems solved by technology

[0002] At present, natural gas compressors mostly use copper and other compatible materials to scrape oil, and the oil scraping effect is poor. As a result, most of the compressors are oil-filled compressors. Causes damage to the gas valve, causing the compressor to fail
At the same time, lubricating oil will also enter the vehicle cylinder, making the vehicle have to clean the cylinder after a period of time

Abstract

The invention discloses a novel oil scraping device for a natural gas compressor. According to the technical scheme, the device comprises an oil baffle plate, an oil pre-scraping ring, a main oil scraping ring and a cover plate, wherein the oil pre-scraping ring and the main oil pre-scraping ring are correspondingly arranged in the oil baffle plate; the cover plate is in contact with the main oilscraping ring and is closely connected to the oil baffle plate through a fastener; the oil pre-scraping ring is arranged at one end, opposite to the cover plate, of the oil baffle plate; the oil pre-scraping ring is coaxial with the main oil scraping ring and sleeves a piston rod of the compressor; an annular groove which is connected to an oil scraping part is formed in the main oil scraping ring; and a compressing spring through which the oil scraping part is close to the piston rod is arranged in the annular groove. The device adopting the abovementioned scheme is good in oil scraping effect and long in service life.

Description

technical field [0001] The invention relates to the field of natural gas compressors, in particular to a novel oil scraping device for natural gas compressors. Background technique [0002] At present, natural gas compressors mostly use copper and other compatible materials to scrape oil, and the oil scraping effect is poor. As a result, most of the compressors are oil-filled compressors. Causes damage to the gas valve, causing the compressor to fail. At the same time, lubricating oil will also enter the vehicle's gas cylinder, making the vehicle have to clean the gas cylinder after a period of time. Therefore how to make the cylinder oil-free, so that the failure rate of the compressor is greatly reduced, and the solution that the automobile does not need to clean the high-pressure gas cylinder is exactly the problem that the inventor will solve. Contents of the invention [0003] In view of the deficiencies in the prior art, the main purpose of the present invention is...
