Description
Technical field
It the utility model is related to gas compressor technical field, more particularly to a kind of buffering hydraulic cylinder.
Background technology
Hydraulic piston type gas compressor, it is that a kind of hydraulic oil is used as power to drive working piston to move back and forth, realizes gas
Cylinder volume changes, and by the intake valve and air bleeding valve of the single effect in gas circuit, completes to gas conveying and compression process.Existing
Have and be not provided with buffer unit in technology in such compressor, hydraulic cylinder is often sent out when doing high-speed motion to stroke terminal
Raw violent mechanical collision, the generation of above mechanical shock not only influences the service behaviour of plant equipment, and can damage hydraulic pressure
The other elements of cylinder and hydraulic system, have very big danger, and in long-time after influence the service life of compressor.
Utility model content
The purpose of this utility model is and a kind of buffering hydraulic proposed in order to solve shortcoming present in prior art
Cylinder.
To achieve these goals, the utility model employs following technical scheme：
A kind of buffering hydraulic cylinder, including cylinder barrel, base is fixedly connected with the bottom of cylinder barrel, end is provided with the end of cylinder barrel
Lid, be connected piston rod in cylinder barrel, it is characterised in that：Guide sleeve is fixedly connected with the bottom of piston rod, on the piston rod
Piston is also socketed, guide sleeve and piston all seal to be oriented to cylinder barrel to be coordinated, and cushion hole is provided with base, is provided with cushion hole
First buffer spring, the first buffer spring coordinate with guide sleeve buffering, cushion plugs are connect in the upper cover of piston rod of pistons front sides, in cylinder
Cylinder front side mating connection buffer cover, buffer cover are arranged in end cap, and cushion hole, cushion hole and buffer cover are provided with the inside of buffer cover
Corresponding matching, first segment discharge orifice is provided with buffer cover, the second throttle orifice, first segment discharge orifice and the second throttling are provided with base
The cavity of Kong Junyu cylinder barrels is connected, the connecting pipe between first segment discharge orifice and the second throttle orifice, and ring is provided with buffer cover
Shape hole, is provided with the second buffer spring in looping pit, and the second buffer spring buffering corresponding with piston coordinates.
Preferably, it is corresponding with the piston in the free end mating connection buffer board of second buffer spring, buffer board
Coordinate.
Preferably, the buffer board can move freely in the cylinder barrel, and buffer board is annular plate-like structure.
Preferably, the buffer board and the looping pit corresponding matching.
Preferably, the cushion plugs are circular frustum structure.
The utility model has the advantage of：The utility model on piston by being provided with throttling and buffer unit, in work
When plug runs to stop, by buffer spring and the collective effect of throttling, row buffering is entered in the motion to piston, makes its commutation flat
Surely, and then cause piston to reduce its speed of service before stop is run to, good buffer effect, avoid to hit in operation and make an uproar
Sound, equipment fault caused by mechanical shock is avoided, improves equipment dependability.
