Abstract
A kind of oxygen compressor oil wiper gasoline-saving device, relates to a kind of gasoline-saving device, particularly relates to a kind of gasoline-saving device increasing sealing buffer pocket at oxygen compressor oil wiper place.Comprise piston shaft, on piston shaft, cover is equipped with oil wiper lid, sealing lining ring is provided with bottom oil wiper lid, top is provided with oil baffle disc, seal ring is provided with between oil wiper lid and sealing lining ring, described oil wiper lid and the surface of contact of seal ring are provided with the circular groove arranged along oil wiper lid center annular, and with the draining ditch of the perpendicular setting of circular groove, cover at described oil wiper and be provided with longitudinally through spill port, cover between portion and oil baffle disc at described oil wiper and be provided with sealing buffer pocket, described sealing buffer pocket and oil wiper lid are fixed together.Its beneficial effect is, after adopting the utility model structure, serves and stops the mist of oil effect of leaking, greatly reduce the outer discharge of oil wiper mist of oil.
Description
Technical field
The utility model relates to a kind of gasoline-saving device, particularly relates to a kind of gasoline-saving device increasing sealing buffer pocket at oxygen compressor oil wiper place.
Background technique
The oxygen produced by space division system need be sent to user after oxygen compressor (being commonly called as oxygen compressor) compression.Owing to there is the gap of about 0.3mm between oil wiper and seal ring, when oxygen compressor runs, oxygen compressor piston shaft back and forth ceaselessly moves at a high speed.When moving downward, oil wiper and seal ring between the two gap increase, and can form negative pressuren zone instantaneously, make lubricant oil arrive between oil wiper lid and seal ring; And when piston shaft moves upward, oil wiper and seal ring between the two gap reduce, certain pressure can be formed instantaneously, lubricant mist can be extruded from the gap between oil wiper and piston shaft, thus cause part mist of oil to be separated out.In real work, in the reciprocating process of oxygen compressor piston rod, some lubricant oil are had to spill from oxygen compressor oil wiper, oxygen contacts with leakage of oil, can the potential safety hazards such as fire be caused, both have influence on the safe operation of oxygen compressor, oxygen compressor power house environment also be impacted simultaneously.
Summary of the invention
The utility model provides a kind of oxygen compressor oil wiper gasoline-saving device, increasing circular groove and draining ditch, adding sealing buffer cover simultaneously, solving the problem that leaks of oil wiper mist of oil by covering at oil wiper.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of oxygen compressor oil wiper gasoline-saving device, comprise piston shaft, on piston shaft, cover is equipped with oil wiper lid, sealing lining ring is provided with bottom oil wiper lid, top is provided with oil baffle disc, seal ring is provided with between oil wiper lid and sealing lining ring, it is characterized in that: described oil wiper lid and the surface of contact of seal ring are provided with the circular groove arranged along oil wiper lid center annular, and with the draining ditch of the perpendicular setting of circular groove, cover at described oil wiper and be provided with longitudinally through spill port, cover between portion and oil baffle disc at described oil wiper and be provided with sealing buffer pocket, described sealing buffer pocket and oil wiper lid are fixed together.
The beneficial effects of the utility model are, after adopting the utility model structure, serve and stop the mist of oil effect of leaking, greatly reduce the outer discharge of oil wiper mist of oil.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is that the A of oil wiper lid in the utility model Fig. 1 is to schematic diagram.
In figure: 1. oil wiper lid; 2. oil baffle disc; 3. seal ring; 4. bolt; 5. seal lining ring; 6. seal buffer pocket; 7. circular groove; 8. spill port; 9. piston shaft; 10. draining ditch.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further described:
From accompanying drawing 1 and accompanying drawing 2, the utility model comprises piston shaft 9, on piston shaft 9, cover is equipped with oil wiper lid 1, sealing lining ring 5 is provided with bottom oil wiper lid 1, top is provided with oil baffle disc 2, seal ring 3 is provided with between oil wiper lid 1 and sealing lining ring 5, described oil wiper lid 1 and the surface of contact of seal ring 3 are provided with the circular groove 7 arranged along oil wiper lid 1 center annular, and with the draining ditch 10 of the perpendicular setting of circular groove 7, described oil wiper lid 1 is provided with longitudinally through spill port 8, be provided with between described oil wiper lid 1 top and oil baffle disc 2 and seal buffer pocket 6, described sealing buffer pocket 6 is fixed together with oil wiper lid 1.
The utility model covers at oil wiper and is provided with the longitudinal draining ditch 10 of three labyrinth, road circular grooves 7 and six roads also, adds the spill port 8 of two φ 10mm.Not only reduce oil wiper lid 1 and seal ring 3 area of contact between the two, and make its with oil wiper lid 1 vacuum end together with, when piston shaft 9 moves upward, the mist of oil that oil wiper lid 1 and seal ring 3 are formed between the two, part sucks back vacuum system through circular groove 7, decreases the mist of oil amount that leaks.After increasing sealing buffer cover 6, and by spill port 8 and oil wiper lid 1 vacuum end together with, make the mist of oil still released be continued to suck back by vacuum system by spill port 8, the labyrinth circular groove 7 on oil wiper lid 1 also plays the effect of leaking of prevention mist of oil.By above-mentioned two measures, greatly reduce the outer discharge of oil wiper mist of oil.
