Description
Technical field
The utility model relates to booster pump field, particularly relates to a kind of booster pump hydraulic piston cylinder.
Background technology
Existing booster pump hydraulic piston is steel part or aluminum material is made, relatively costly, and when piston is because of outward
Boundary's reason occurs coordinating tension or stuck situation, can cause the surface of oil cylinder inner wall and pull, cause chain scrapping.
China Patent No.: 200910096209.1 disclose a kind of hydraulic prop piston, including piston body, y-type seal ring,
The upper inner of y-type seal ring has protuberance, and whole y-type seal ring is arranged in the caulking groove of piston body bottom, the bottom land of caulking groove
While be that piston body outer wall radially extends and forms, described piston body is macromolecular material single piece;Bottom land limit with described caulking groove
On corresponding groove top margin, there is the recess that a shape matches with described y-type seal ring protuberance.This design is that piston body is adopted
Make of macromolecular material alternative metals material, thus be no longer necessary to consideration and the problems such as guide ring, extruding circle and packing ring are set, both
Decrease piston element, reduce production cost, also extend the service life of piston, improve reliability;Even if occurring " dead
Post " phenomenon also will not damage pillar column casing, uses y-type seal ring protuberance with piston body recess after mutually embedding structure, although to eliminate
Anti-extrusion ring, but, the protuberance that piston body recess is arranged makes y-type seal ring assembling difficulty, changes inconvenience, and, through type
Inner chamber be unfavorable for that booster pump works, need equal power effect could realize reinforcing, not only increasing action power on the piston rod
Thus cause the wasting of resources, and the intensity of piston rod increases thus increases cost.
Utility model content
Therefore, for above-mentioned problem, the utility model provides a kind of booster pump hydraulic piston cylinder, and it mainly solves existing
There is Y-shaped ring assembling in technology, change difficulty, the high problem of Piston Machining cost.
For achieving the above object, the utility model have employed techniques below scheme: a kind of booster pump hydraulic piston cylinder, including
Cylinder, upper and lower two end faces of described cylinder are arranged with the first hydraulic chamber and the second hydraulic chamber respectively inwards, and described
The diameter of one hydraulic chamber, less than the diameter of the second hydraulic chamber, is arranged between described first hydraulic chamber and the second hydraulic chamber
Having connection chamber, described connection chamber is provided with taper inlet near one end of the second hydraulic chamber, described cylinder upper and lower
Two ends are respectively arranged with the first convex edge and the second convex edge, and the outer surface in the middle part of described cylinder is provided with projection, described first convex
It is provided with y-type seal ring between edge and projection.
Further, described cylinder is that polyformaldehyde is made.
Further, the bottom surface of described first hydraulic chamber is inwardly arranged to arcwall face.
Further, folded between described second convex edge and cylinder angle is set to rounding.
By using preceding solution, the beneficial effects of the utility model are: this booster pump hydraulic piston cylinder, by setting
Put connection chamber and connect the first hydraulic chamber and the second hydraulic chamber, and the diameter of the first hydraulic chamber is less than the second hydraulic cavities
The diameter of room, during so that piston rod acts in the second hydraulic chamber, liquid flows to the first hydraulic cavities by connecting chamber
Indoor, act on object by connector, are effectively increased hydraulic coupling, play the effect of reinforcing, the second convex edge and projection it
Between form the groove that closes of three side sealing, the beneficially installation of y-type seal ring, and play the supporting role to y-type seal ring;Enter one
Step, cylinder is that polyformaldehyde is made, and is on the one hand possible to prevent piston to occur coordinating tension or stuck phenomenon because of extraneous factor,
Phenomenons such as pulling is caused to the inwall of oil cylinder, on the other hand, because booster pump uses brake fluid, containing moisture content, and most absolutely
The macromolecular material of number, such as nylon etc., there is water imbibition, size can be caused unstable, especially because working in aqueous environments for a long time
It is in hot environment, is worse off more rapid, and final stuck phenomenon occur;The bottom surface of the first hydraulic chamber is inwardly arranged
Camber face, prevents first liquid chamber effluent body or forms negative pressure condition, adsorbing piston rod, cause pause and transition in rhythm or melody phenomenon;The
Angle folded between two convex edges and cylinder is set to rounding, increases the intensity of the second convex edge.
Brief description
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
In conjunction with the drawings and specific embodiments, the utility model is further illustrated.
The utility model embodiment is:
With reference to Fig. 1, a kind of booster pump hydraulic piston cylinder, including cylinder 1, described cylinder 1 is made for polyformaldehyde, described cylinder
Be arranged with hydraulic chamber 11 and hydraulic chamber 12 respectively inwards on upper and lower two end faces of 1, the bottom surface of described hydraulic chamber 11 to
Inside being arranged to arcwall face, the diameter of described hydraulic chamber 11 is less than the diameter of hydraulic chamber 12, described hydraulic chamber 11 and hydraulic pressure
Being provided with connection chamber 2 between chamber 12, described connection chamber 2 is provided with taper inlet 3 near one end of hydraulic chamber 12,
The upper/lower terminal of described cylinder 1 is respectively arranged with convex edge 4 and convex edge 5, and angle folded between described convex edge 4 and cylinder 1 is set to
Rounding 6, the outer surface in the middle part of described cylinder 1 is provided with projection 7, is provided with Y type and seals between described convex edge 4 and projection 7
Circle 8.
Working method of the present utility model is: this booster pump hydraulic piston cylinder, connects hydraulic cavities by arranging connection chamber 2
Room 11 and hydraulic chamber 12, and the diameter of hydraulic chamber 11 is less than the diameter of hydraulic chamber 12, so that piston rod effect
When in hydraulic chamber 12, liquid flows to, in hydraulic chamber 11, act on object by connector, effectively by connecting chamber 2
Add hydraulic coupling, play the effect of reinforcing, between convex edge 5 and projection 7, form the groove that closes of three side sealing, beneficially Y type is close
The installation of seal 8, and play the supporting role to y-type seal ring 8, cylinder 1 is made for polyformaldehyde, is on the one hand possible to prevent to live
Plug occurs coordinating tension or stuck phenomenon because of extraneous factor, causes, to the inwall of oil cylinder, phenomenons such as pulling, on the other hand, because of
Booster pump uses brake fluid, containing moisture content, and most of macromolecular material, as nylon etc. has water imbibition, and can be because of
Working in aqueous environments for a long time, causing size unstable, especially in hot environment, malignant condition is more rapid, finally goes out
Existing stuck phenomenon.
Although specifically show and describe the utility model in conjunction with preferred embodiment, but those skilled in the art should
