Description
Technical field
It the utility model is related to air compressor field, and in particular to a kind of oil saving structure of air compressor.
Background technology
In the process of running, fuselage transmission device needs good lubrication to air compressor, in greasing, lubricating oil
Cylinder is easily entered by the gap between piston rod and packing ring, causes to carry lubricating oil etc. in oil leak, compressed air secretly
Phenomenon, have an effect on the running of lubricant effect and air compressor.
Utility model content
The utility model is in view of the above-mentioned problems, provide a kind of oil saving structure of air compressor.
The purpose of this utility model can be realized by following technical proposals：A kind of oil saving structure of air compressor,
Including piston rod, one end of the piston rod is arranged in a gas circuit, and the other end of piston rod is arranged in an oil circuit, piston rod
On pass through between be sequentially provided with filler seat, closed chamber, gland and flange, for blocking gas circuit and oil
Road；The end of the filler seat is fixed in the neck of air compressor inwall, shape on the face contacted with closed chamber of filler seat
It is in depression, forms the boss corresponding with depression on the face touched with filler seated connection of the closed chamber, the boss of closed chamber is caught in
In the depression of filler seat, then closed chamber is set to be connected and fixed on filler seat by fixing bolt, shape on the another side of closed chamber
Into stuffing hole, stuffing hole is built-in with double-deck filler, and double-deck filler is the ceramic packing ring being placed on piston rod and is located at ceramics and fills out
Expect the carbon packing outside ring；The gland is covered on the other end of the closed chamber, is formed to stretch on gland and filled out
Expect the projection in hole, the face being in contact with double-deck filler of the projection is circular arc concave surface；The face being in contact with oil circuit of the flange
On offer annular groove, is provided with oil sealing in annular groove；The flange, gland and closed chamber by regulating bolt successively
Pass through and be connected.
The utility model has the advantage of：By using the ceramic packing ring in the oil sealing sealing and closed chamber on flange,
The double sealing structure of carbon packing barrier, the lubricating oil for avoiding oil circuit are brought gas circuit into by piston rod, fundamentally avoided
The leakage of lubricating oil, double-deck packing seal is good, and oil sealing installation is simple, plays splendid oil-saving effect.In addition, closed chamber is installed
In on filler seat, filler seat is directly clamped among air compressor inwall, and the installation and fixation of whole oil saving structure are very easy.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Marked in figure as follows：
1 piston rod, 2 gas circuits, 3 oil circuits, 4 filler seats, 5 depressions, 6 closed chambers, 7 fixing bolts, 8 ceramic packing rings, 9 carbons
Filler, 10 glands, 11 circular arc concave surfaces, 12 flanges, 13 oil sealings, 14 regulating bolts.
Embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with accompanying drawing, becomes apparent from those skilled in the art
Ground understands how to put into practice the utility model.Although describing the utility model with reference to its preferred embodiment, these
Embodiment simply illustrates, rather than limitation the scope of the utility model.
Referring to Fig. 1, a kind of oil saving structure of air compressor, including piston rod 1, one end of the piston rod 1 are arranged at
In one gas circuit 2, the other end of piston rod 1 is arranged in an oil circuit 3, is set successively between passing through on piston rod 1
There are filler seat 4, closed chamber 6, gland 10 and flange 12, for blocking gas circuit 2 and oil circuit 3；The end of the filler seat 4 is consolidated
It is scheduled in the neck of air compressor inwall, depression 5, the closed chamber 6 is formed on the face contacted with closed chamber 6 of filler seat 4
The face contacted with filler seat 4 on formed with 5 corresponding boss of depression, the boss of closed chamber 6 is caught in the depression 5 of filler seat 4
It is interior, then closed chamber 6 is connected and fixed on filler seat 4 by fixing bolt 7, stuffing hole is formed on the another side of closed chamber 6,
Stuffing hole is built-in with double-deck filler, and double-deck filler is the ceramic packing ring 8 being placed on piston rod 1 and is located at outside ceramic packing ring 8
Carbon packing 9；The gland 10 is covered on the other end of the closed chamber 6, is formed to stretch on gland 10 and filled out
Expect the projection in hole, the face being in contact with double-deck filler of the projection is circular arc concave surface 11, to be to fill out because being piston rod 1
Material leaves the wider space being extruded, as surplus；It is recessed that annular is offered on the face being in contact with oil circuit 3 of the flange 12
Groove, annular groove is interior to be provided with oil sealing 13；The flange 12, gland 10 and closed chamber 6 are sequentially passed through by regulating bolt 14
And it is connected.
Wherein, the ceramic packing ring 8 of double-deck filler has excellent acidproof heat-proof performance, and it is used as and is enclosed on piston rod 1
Liner.Carbon packing 9 is that carbon packing is that braiding forms after being pre-oxidized by acrylic fiber around being laminated by carbon packing
Packing, surface uses to be formed containing graphite particle ptfe emulsion and lubricated, oil can be sealed, be used the longevity
Life length.
In use, when piston rod 1 is movable, pass through the ceramic packing ring in the sealing of oil sealing 13 and closed chamber 6 on flange 12
8th, carbon packing 9 obstructs, and the lubricating oil for avoiding oil circuit 3 brings gas circuit 2 into by piston rod 1, fundamentally avoids lubricating oil
Leakage, plays splendid oil-saving effect.
It should be pointed out that for the utility model through absolutely proving, can also have a variety of conversion and the implementation of remodeling
Scheme, it is not limited to the specific embodiment of above-mentioned embodiment.Above-described embodiment as just explanation of the present utility model, and
