Description
Technical field
The present invention relates to natural gas compressor field, in particular to the novel oil-scraping device of a kind of natural gas compressor.
Background technique
Natural gas compressor mostly uses copper etc. to meet material frizing at present, and it is poor that there are scraping effects, leads to the big portion of compressor
Dividing is to have hydraulic shrinking machine, and the lubricating oil into cylinder causes oil liquid to be hardened by cylinder high temperature, and then causes into air valve etc.
Air valve damage, makes compressor break down.Lubricating oil can also enter mounted gas cylinder simultaneously, so that vehicle must not after for a period of time
Unclear drexel bottle.Therefore how to make cylinder oil-free, so that the failure rate of compressor substantially reduces, also allow automobile not have to cleaning high
The scheme of air bottle is exactly the present inventor's problem to be solved.
Summary of the invention
In view of the deficienciess of the prior art, the natural gas good the main purpose of the present invention is to provide a kind of scraping effect
The novel oil-scraping device of compressor.
To achieve the above object, the present invention provides the following technical scheme that a kind of novel frizing of natural gas compressor fills
It sets, including oil baffle, pre- oil-scraping ring, main oil-scraping ring and cover board, the pre- oil-scraping ring and main oil-scraping ring are separately positioned on gear
Inside oiled-plate method, the cover board contacts with main oil-scraping ring and passes through fastener and closely connect with oil baffle, the pre- oil-scraping ring setting
One end of opposing cover plates on oil baffle, the pre- oil-scraping ring and main oil-scraping ring are coaxially disposed and are set in the piston rod of compressor
On.
Preferably, it is provided with annular groove on the main oil-scraping ring, the annular groove is connected with frizing portion, in the annular groove
It is provided with so that the compressed spring of piston rod is close in frizing portion.
Preferably, the fastener is fastening screw or clamp.
Preferably, the making material of the pre- oil-scraping ring is polyurethane.
Preferably, the making material of the main oil-scraping ring is polyether-ether-ketone.
The present invention has the following advantages compared with the prior art, and integral installation is below compressor seal ring, close to bent
Axle box side, when installation, pre- oil-scraping ring needed to be installed to crankcase side, and when the compressor is operating, pre- oil-scraping ring plays for the first time
Sealing effect, then main oil-scraping ring plays the role of main seal effect, and oil baffle plays the lubricating oil for stopping to splash.Relative to
It is compared in the prior art simply by the scheme of a frizing, scheme provided by the present application can have better frizing to imitate
Fruit.Existing equipment can only wipe the lubricating oil into cylinder off on a small quantity, and the present invention can make the lubricating oil into cylinder subtract significantly
It is few to can be ignored substantially.
Detailed description of the invention
Fig. 1 is a kind of sectional view of the novel oil-scraping device of natural gas compressor of the invention.
In figure: 1, oil baffle；2, pre- oil-scraping ring；3, main oil-scraping ring；4, cover board；5, fastener.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
As shown in Figure 1, a kind of novel oil-scraping device of natural gas compressor, including oil baffle 1, pre- oil-scraping ring 2, main frizing
Ring 3 and cover board 4, the pre- oil-scraping ring 2 and main oil-scraping ring 3 are separately positioned on inside oil baffle 1, and the cover board 4 is scraped with master
Oil ring 3 is contacted and is closely connect by fastener 5 with oil baffle 1, and opposing cover plates 4 are arranged on oil baffle 1 in the pre- oil-scraping ring 2
One end, the pre- oil-scraping ring 2 is coaxially disposed with main oil-scraping ring 3 and is set on the piston rod of compressor.
A kind of novel oil-scraping device of natural gas compressor of the invention, integral installation below compressor seal ring,
Close to crankcase side, when installation, pre- oil-scraping ring 2 needed to be installed to crankcase side, and when the compressor is operating, pre- oil-scraping ring 2 rises
To first time sealing effect, then main oil-scraping ring 3 plays main seal effect, and oil baffle 1 plays the lubricating oil for stopping to splash
Effect.It is compared in compared with the existing technology simply by the scheme of a frizing, scheme provided by the present application can have more
Good scraping effect.Existing equipment can only wipe the lubricating oil into cylinder off on a small quantity, and the present invention can make the profit into cylinder
Lubricating oil considerably reduces to can be ignored substantially.
Preferably, annular groove is provided on the main oil-scraping ring 3, the annular groove is connected with frizing portion, the annular groove
It is inside provided with so that the compressed spring of piston rod is close in frizing portion.Referring to Fig.1, the purpose designed in this way is made with compressed spring
Main oil-scraping ring 3 can bear the working environment for a long time with high-temperature, wipe remaining lubricating oil off close to piston rod.Due to master
It scrapes oil baffle to be bonded inside slideway very much, can largely block oil liquid and splash into cylinder.
Preferably, the fastener 5 is fastening screw or clamp.Fastening screw or clamp can make cover board 4
It is fitted closely with oil scraping plate.
Preferably, the making material of the pre- oil-scraping ring 2 is polyurethane.
Preferably, the making material of the main oil-scraping ring 3 is polyether-ether-ketone.
Since oil-scraping ring in the prior art is all brass material, it is poor that there are scraping effects, and pre- oil-scraping ring 2 is adopted in this programme
With the good polyurethane material of oil resistivity, main oil-scraping ring 3 makes oil-scraping ring close to work using a kind of wear-resisting PEEK material with spring
Stopper rod can bear the working environment for a long time with high-temperature, to have longer use while guaranteeing scraping effect
Service life.
The above is only a preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
Those of ordinary skill for, several improvements and modifications without departing from the principles of the present invention, these improvements and modifications
It should be regarded as protection scope of the present invention.
