Abstract

The utility model relates to an oil scraping ring which comprises a ring-shaped body, wherein scrapers extend from two ends of the ring-shaped body in the radial direction, the scrapers are connected with the ring-shaped body through cone-shaped rings, and a plurality of oil guiding holes penetrating through the side wall of the ring-shaped body are arranged in the outer circumference surface of the ring-shaped body. According to the oil scraping ring, the area of an oil return chute formed by the outer wall of the ring-shaped body, the cone-shaped rings and the scrapers is greatly increased, so oil leakage is avoided, and meanwhile oil in the oil return chute is enabled to return in time and the oil content of compressed gas is reduced.

Description

A kind of scraper ring

Technical field

The utility model relates to a kind of scraper ring that can stop lubricant oil to enter cylinder body, belongs to fluid varactor machine part field.

Background technique

In most of food or the packaging industry, the gas that requires piston compressor to compress is without oil, so scraper ring all is installed in the cylinder body of these piston compressors.The scraper ring that generally uses in the industry is an annular solid that has the perforation rectangle groove in end face, bottom surface, and the thickness of these scraper rings is all smaller, and the rectangle groove degree of depth of offering is also smaller.Such scraper ring in use because the Area comparison of its rectangle groove is little, the backflow of lubricant oil is very slow, often can overflow rectangle groove, causes oil leakage phenomenon, so that it is larger to compress the gas oil content that.

The model utility content

The utility model purpose is that a kind of backflow that improves lubricant oil is provided in order to overcome the deficiencies in the prior art, the scraper ring of avoiding oil leakage phenomenon to occur.

For achieving the above object, the technical solution adopted in the utility model is: a kind of scraper ring, comprise annular solid, and the two ends of described annular solid all radially are extended with scraper; Described scraper all is connected by tapered collar with annular solid; On the outer peripheral surface of described annular solid, all have the oil guiding hole of a plurality of perforation annular solid sidewalls.

Preferably, described oil guiding hole is track type, and the length of oil guiding hole is 3/4 of annular solid height.

Preferably, described oil guiding hole is five, and on the uniform outer wall that is arranged in annular solid.

Because the utilization of technique scheme, the utility model compared with prior art has following advantages:

A kind of scraper ring of the utility model scheme, it connects scraper by tapered collar respectively at the annular solid two ends, and offer a plurality of oil guiding holes at the annular solid outer wall, so that the oil-return groove area that annular solid outer wall, tapered collar and scraper form increases greatly, when avoiding leakage of oil, also so that the oil in the oil-return groove can in time reflux, reduced the oil content of pressurized gas.

Description of drawings

Below in conjunction with accompanying drawing technical solutions of the utility model are described further:

Accompanying drawing 1 is the stereogram of the utility model scraper ring;

Accompanying drawing 2 is the sectional view of the utility model scraper ring;

Wherein: 1, annular solid; 2, scraper; 3, tapered collar; 4, oil guiding hole.

Embodiment

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

Accompanying drawing

1,2 is a kind of scraper ring described in the utility model, comprises annular solid 1, and the two ends of described annular solid 1 all radially are extended with scraper 2; Described scraper 2 all is connected by tapered collar 3 with annular solid 1; On the outer peripheral surface of described annular solid 1, all have the oil guiding hole 4 of a plurality of perforation annular solid 1 sidewalls; The oil-return groove area that described annular solid 1 outer wall, tapered collar 3 and scraper 2 form increases greatly, when avoiding leakage of oil, also so that the oil in the oil-return groove can in time reflux; Described oil guiding hole 4 is five, and on the uniform outer wall that is arranged in annular solid 1; Described oil guiding hole 4 is track type, and the length of oil guiding hole 4 is 3/4 of annular solid 1 height; By the setting of track type oil guiding hole, accelerated the backflow of lubricant oil, effectively avoided leakage of oil, greatly reduce the oil content of pressurized gas, improved the quality of production and manufacturing efficiency.

Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.

Claims
