Abstract
The utility model discloses a pneumatic cylinder is received and is defiled ring, it is to the abominable working condition of pneumatic cylinder, all sets up a step form breach receiving the both ends of dirty ring after expanding, breachs orientation in both ends is opposite, constitutes " Z " style of calligraphy structure, installs that this both ends breach is seamless butt joint behind the piston both ends of pneumatic cylinder. The pneumatic cylinder is received and is defiled ring of this structure can effectively prevent impurity and high temperature highly -compressed air to pass through, has simple structure, preparation simple to operate's characteristics, has solved the problem that current pneumatic cylinder piston packaging spare received impurity damage, the high temperature highly -compressed air of the easy adhesion of small grit thing in the piston wear -resistants ring surface and fish tail cylinder inner chamber and hydro -cylinder to burn out wear -resistant ring and piston packaging spare easily, has improved hydro -cylinder life.
Description
Technical field
This utility model is related to hydraulic jack, and in particular to receive dirty ring for various hydraulic jacks are antipollution.
Background technology
Hydraulic cylinder adopts targeted design typically according to its applying working condition, will with the use and performance that meet hydraulic cylinder
Ask, one of targeted design is exactly the dirty ring structure of receiving at piston two ends.At present this receive dirty ring make it is certain thickness
After ring-type, it is installed in the cylindrical groove at piston two ends.Existing hydraulic cylinder receives dirty ring generally using after spreading out
Structure of the two ends for hypotenuse, is installed in the structure behind hydraulic cylinder piston two ends and presents with hypotenuse breach, that is, there is R-joining
Gap, its adverse consequences are as follows:One is that sealing piston of hydraulic cylinder part is easily damaged by impurity, and small grit thing is easily adhered
The surface tear inner cavity of cylinder of piston wearing ring is so as to reducing hydraulic cylinder service life;Two is the air or height not drained in oil cylinder
Speed is easily caused the high temperature that adiabatic compression causes, pressure-air by receiving dirty circumferential weld gap when starting, so as to cause wearing ring, piston
Sealing member burns and even burns, and makes oil cylinder fail.
The content of the invention
The purpose of this utility model be to provide one kind can effectively prevent impurity and High Temperature High Pressure air from passing through, simple structure,
The convenient hydraulic cylinder of fabrication and installation receives dirty ring, solves that sealing piston of hydraulic cylinder part is easily damaged by impurity, small grit thing holds
It is easy-adhesion in the wear-resistant ring surface of piston and to scratch the High Temperature High Pressure air in inner cavity of cylinder and oil cylinder to burn out wearing ring close with piston
The problem of sealing, improves oil cylinder service life.
To realize object above, a kind of hydraulic cylinder of this utility model receives dirty ring for the severe working condition of hydraulic cylinder,
Two ends after the dirty ring received launches are respectively provided with a step-like breach, the two ends breach towards conversely, constitute " Z " font structure,
It is in seamless docking installed in the two ends breach behind the piston two ends of hydraulic cylinder.
The dirty ring of receiving of said structure adopts " Z " font structure, ties different from the dirty ring of receiving with hypotenuse breach of prior art
Structure, one can be preferably protect sealing piston of hydraulic cylinder part from impurity damage, avoid small grit thing from sticking to work
The surface tear inner cavity of cylinder of wearing ring is filled in so as to play a part of to extend hydraulic cylinder service life;Two can be prevented from oil cylinder
The air or high-speed starting not drained causes the high temperature that adiabatic compression causes, pressure-air by receiving dirty ring, wear-resistant so as to cause
Ring, piston seal burn, burn, and make oil cylinder fail.
A kind of hydraulic cylinder of this utility model is received dirty ring and is located at the piston two ends of hydraulic cylinder, ties with piston seal and wearing ring
Close and use, can effectively prevent in-oil cylinder oil from causing the damage of sealing member because being mixed with external substance, and guarantee that sealing member has length
Service life;When being used in combination with piston seal, metal lining, there is impurity submergence function because receiving dirty ring, can be anti-
Only inner cavity of cylinder surface the aspect such as is scratched by small grit thing and plays very important effect;It is of the present utility model to receive dirty ring and adopt
With PTFE material, as PTFE material hardness is low and density is not high, therefore there is impurity submergence function, impurity absorption can received dirt
Ring surface, in case atomic little impurity damages sealing member in the fluid in hydraulic cylinder, extends the service life of sealing member, in addition should
Material has good thermostability, can prevent the wearing ring caused because of adiabatic compression and piston seal from burning or burning and causing oil
Cylinder fails.
Description of the drawings
Fig. 1 is that a kind of hydraulic cylinder of this utility model receives dirty ring installment state main cross section structure diagram.
Fig. 2 is that a kind of hydraulic cylinder of this utility model receives dirty ring deployed condition structural representation.
Reference:Receive dirty ring 1, wearing ring 2, piston packing 3, piston 4.
Specific embodiment
Dirty ring of receiving to a kind of hydraulic cylinder of this utility model with reference to the accompanying drawings and detailed description is made further specifically
It is bright.
A kind of hydraulic cylinder of this utility model shown in Fig. 1 and Fig. 2 receives dirty ring for the severe working condition of hydraulic cylinder, is receiving dirt
Two ends after ring 1 launches are respectively provided with a step-like breach, and the two ends breach is towards conversely, composition " Z " font structure, installs
Behind 4 two ends of piston of hydraulic cylinder, the two ends breach is in seamless docking, and this receives dirty ring using PTFE material making.
Claims (1)
1. a kind of hydraulic cylinder receives dirty ring, it is characterized in that:Receive dirty ring launch after two ends be respectively provided with a step-like breach, this two
End breach is towards conversely, composition " Z " font structure, is in seamless right installed in the two ends breach behind the piston two ends of hydraulic cylinder
Connect.
