Problems solved by technology

At present, the oil leakage at the scraper ring of the piston compressor used in our factory is relatively serious, which leads to the consumption of lubricating oil in the air compressor and waste
For gases that require no oil, such as PET compressors used in the food industry, if the lubricating oil brought by the piston rod penetrates into the cylinder, the gas will be polluted and the piston rings and packings will wear prematurely.

Embodiment Construction

[0012] The present invention is described below in conjunction with accompanying drawing.

[0013] attached figure 1 It is an oil scraper ring according to the present invention, which includes an oil scraper ring piece and a positioning pin 6 arranged in the oil scraper ring piece. 2 and the lower end oil scraper ring 3; the oil scraper ring is provided with an oil return groove 4 with a width of 12-16 mm to increase the area of ​​the oil return channel; the middle end oil scraper ring 2 and the lower end oil scraper ring There are three oil grooves 5 with a width×depth of 16mm×1.5mm on the piece 3, and six oil grooves 5 of 16mm×1.5mm on the upper oil scraper ring piece 1. Through the design of the oil groove 5, the end face The oil can flow back in time and quickly; positioning pins 6 are arranged between the upper oil scraper ring 1, the middle oil scraper ring 2 and the lower oil scraper ring 3 to prevent relative rotation of the oil scraper rings, overlapping openings, a...

Abstract

The invention discloses an oil scraper ring which comprises a scraper ring plate and positioning pins disposed in the scraper ring plate. The oil scraper ring is characterized in that the scraper ring comprises an upper scraper ring plate, a middle scraper ring plate and a lower scrape ring plate. The scraper ring plate is provided with oil return grooves 12-16mm in width. The middle scraper ring plate and the lower scraper ring plate are provided with three oil grooves in 16mm*1.5mm in width and depth. The upper scraper ring plate is provided with six oil grooves 16mm*1.5mm in width and depth. The oil return grooves of the oil scraper ring are widened, and the area of an oil return channel is enlarged. With the oil grooves on the oil scraper ring, oil at the ends can flow back timely. The positioning pins are disposed between the oil scraper rings, so that mutual rotation of the oil scraper rings is avoided. Openings of the oil scraper rings are stacked, so that oil leakage is avoided. Therefore, the problem of oil leakage of the oil scraper ring is solved thoroughly.

Description

technical field [0001] The invention relates to an oil scraping ring, in particular to an oil scraping ring preventing lubricating oil from entering a cylinder, and belongs to the technical field of engineering components. Background technique [0002] Oil wiper rings are mainly used in oil-free lubricated piston compressors to prevent the lubricating oil in the crankcase from entering the cylinder, so as to achieve the purpose of compressing gas without oil. At present, the oil leakage from the scraper ring of the piston compressor used in our factory is relatively serious, which leads to the consumption of lubricating oil of the air compressor and waste. For gases that require no oil, such as PET compressors used in the food industry, if the lubricating oil carried by the piston rod penetrates into the cylinder, the gas will be polluted and the piston rings and packing will wear prematurely. Contents of the invention [0003] In view of the above-mentioned existing tech...
