Abstract
The invention discloses a both-way oil wiper which comprises an oil wiper body. The both-way oil wiper is characterized in that the oil wiper body comprises two oil wiping rings, mirror images are arranged at two ends of the oil wiper body, return chutes are arranged on the oil wiping rings, three oil extraction through holes are arranged on a pericardial face of the oil wiper body, and the diameter of the oil extraction through holes is 10mm. The oil wiper body is made of polyether-ether-ketone (PEEK) non-metallic material. In the both-way oil wiper, the two mirror images are integrally arranged, and the both-way oil wiper is provided both-way blade edges and made of the non-metallic material, achieves good sealing performance, cannot scrape a piston rod, prolongs service of a sealing system of a compressor, reduces leakage of compressed air and pollution of lubricating oil, prolongs replacement time of the lubricating oil, saves consumption of the lubricating oil and strengthens environmental protection.
Description
Technical field
The present invention relates to a kind of oil wiper, refer in particular to a kind of being used in and stop lubricant oil to enter the Bidirectional oil scraper of cylinder in air compressor, belong to mechanical engineering technical field.
Background technique
Oil wiper is mainly used in oil-free lubricating piston formula compressor, is used for stoping the lubricant oil in crankcase to enter cylinder, thereby reaches pressurized gas without the purpose of oil.4RDSB one 3 type reciprocating-piston compressors, the cylinder arrangement of this unit is symmetrical balance-type, and each cylinder is provided with a cover packing seal, and in each, body is provided with a cover oil wiper.Oil wiper is used for preventing that the lubricant oil of crankcase from leaking from piston rod, still finds through long-term the use, and more lubricant oil is not only wasted in the frequent leakage of oil of oil wiper hermetic unit, and has a strong impact on the safe operation of unit.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed a kind of Bidirectional oil scraper that can solve the scraper ring Leakage.
Technical solution of the present invention is achieved in that a kind of Bidirectional oil scraper, comprises the oil wiper body, it is characterized in that: described oil wiper body comprises scraper ring; Described scraper ring has two, and mirror image is arranged on the two ends of oil wiper body; Described scraper ring is provided with oil-return groove; Described oil wiper body circumferential surface is provided with the oil extraction through hole.
Preferably, described oil extraction through hole has three, and diameter is 10mm.
Preferably, described oil wiper body is made by polyether-ether-ketone (PEEK) nonmetallic material.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
A kind of Bidirectional oil scraper of the present invention, two scraper ring mirror images are set to one, have two-way sword limit, adopt nonmetallic material to make, reached sealability preferably, and can the scratch piston rod, extend the working life of compressor seal system, reduced the leakage of pressurized gas and the pollution of lubricant oil, extended the replacing time of lubricant oil, save the consumption of lubricant oil, strengthened environmental protection.
Description of drawings
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is for being the stereogram of a kind of scraper ring of the present invention;
Accompanying drawing 2 is for being the plan view of a kind of scraper ring of the present invention;
Accompanying drawing 3 for for the A-A of a kind of scraper ring of the present invention to sectional view;
Wherein: 1, oil wiper body; 2, scraper ring; 3, oil-return groove; 4, oil extraction through hole.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Accompanying drawing 1 is a kind of Bidirectional oil scraper of the present invention, comprises oil wiper body 1, and described oil wiper body 1 comprises scraper ring 2; Described scraper ring 2 has two, and mirror image is arranged on the two ends of oil wiper body 1; Described scraper ring 2 is provided with oil-return groove 3; Described oil wiper body 1 circumferential surface is provided with oil extraction through hole 4; Described oil extraction through hole 4 has three, and diameter is 10mm.Described oil wiper body 1 is made by polyether-ether-ketone (PEEK) nonmetallic material, has self lubricity, and elasticity is much larger than metal, and temperature tolerance, good thermal stability have sealability preferably; The every face of each scraper ring 2 on oil wiper body 1 is provided with oil-return groove 3, oil mass hour is led away oil by oil-return groove 3, and when scraping oil mass when larger, oil directly flows into fuel tanks from oil extraction through hole 4, this kind structure can thoroughly be removed the oil on piston rod, has guaranteed to scrape oil quality.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
A kind of Bidirectional oil scraper of the present invention, two scraper ring mirror images are set to one, have two-way sword limit, adopt nonmetallic material to make, reached sealability preferably, and can the scratch piston rod, extend the working life of compressor seal system, reduced the leakage of pressurized gas and the pollution of lubricant oil, extended the replacing time of lubricant oil, save the consumption of lubricant oil, strengthened environmental protection.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow person skilled in the art scholar can understand content of the present invention and be implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
