Abstract
The present invention provides a kind of large reciprocating technique compressor frizing ring assemblies, including compressor body, piston rod is provided with compressor body, described piston rod is provided with the first oil-scraping ring and the second oil-scraping ring, described oil-scraping ring periphery, which is equipped with, scrapes oil box, the second described oil-scraping ring side is provided with pulsation sealing ring, and described side of second oil-scraping ring away from the first oil-scraping ring is provided with oil sealing, and described piston rod is located at side of the oil sealing away from oil-scraping ring and is provided with dynamic sealing ring.Described dynamic sealing ring surface nitrogen air admission hole and nitrogen venthole, described nitrogen air admission hole is corresponding with nitrogen outlet hole site, and nitrogen air admission hole is equal apart from the distance of dynamic sealing ring central point with nitrogen venthole.This product strengthens scraping effect, the leakage rate of less lubricating oil, largely reduces the wasting of resources and the pollution to process gas caused by the leakage of lubricating oil, very useful.
Description
Technical field
The present invention relates to a kind of reciprocating technique compressor, more particularly to a kind of large reciprocating technique compressor oil-scraping ring
Component.
Background technology
Domestic large reciprocating technique compressor is both referred to American Petroleum Institute's API618 standards design production, oil-scraping ring
Amount of leakage is mainly made up of greatly two reasons：Very little, scraping effect is bad for frizing ring group number；Filler assembly gas leakage, material gas
Oil-scraping ring is caused to fail into frizing ring assemblies and lubricating oil reaction generation polymer, so needing a kind of large reciprocating technique
Compressor frizing ring assemblies could solve these problems.
The content of the invention
For existing technical deficiency, the present invention provides a kind of large reciprocating technique compressor frizing ring assemblies.
To achieve these goals, the technical solution used in the present invention is：A kind of large reciprocating technique compressor is scraped
Oil ring component, including compressor body, are provided with piston rod in compressor body, described piston rod be provided with the first oil-scraping ring with
Second oil-scraping ring, described oil-scraping ring periphery, which is equipped with, scrapes oil box, and the second described oil-scraping ring side is provided with pulsation sealing ring, institute
Side of second oil-scraping ring away from the first oil-scraping ring stated is provided with oil sealing, and described piston rod is located at one of oil sealing away from oil-scraping ring
Side is provided with dynamic sealing ring.
Described dynamic sealing ring surface nitrogen air admission hole and nitrogen venthole, described nitrogen air admission hole and nitrogen outlet
Hole site is corresponding, and nitrogen air admission hole is equal apart from the distance of dynamic sealing ring central point with nitrogen venthole.
Described oil sealing is fluorubber outside framework oil seal, and the quantity of fluorubber outside framework oil seal is two.
Described diameter of piston rod is 30mm-300mm.
Beneficial effects of the present invention：This product strengthens scraping effect, the leakage rate of less lubricating oil, largely reduces
The wasting of resources caused by the leakage of lubricating oil and the pollution to process gas, it is very useful.
Brief description of the drawings
Fig. 1 is the sectional view of the present invention；
Fig. 2 is the dynamic sealing ring of the present invention.

Periphery, which is equipped with, scrapes oil box 4, and the described ring side of the second frizing 3 is provided with pulsation sealing ring 5, and the second described oil-scraping ring 3 is remote
The side of first oil-scraping ring 2 is provided with oil sealing 6, and described piston rod 1 is located at side of the oil sealing 6 away from oil-scraping ring and is provided with dynamic sealing
Ring 7.
The described surface nitrogen air admission hole 8 of dynamic sealing ring 7 and nitrogen venthole 9, described nitrogen air admission hole 8 and nitrogen
The position of venthole 9 is corresponding, and nitrogen air admission hole 8 is equal apart from the distance of the central point of dynamic sealing ring 7 with nitrogen venthole 9.
Described oil sealing 6 is fluorubber outside framework oil seal, and the quantity of fluorubber outside framework oil seal is two.
Described 1 a diameter of 20mm-300mm of piston rod.
Beneficial effects of the present invention：This product strengthens scraping effect, the leakage rate of less lubricating oil, largely reduces
The wasting of resources caused by the leakage of lubricating oil and the pollution to process gas, it is very useful.
