Technical Field
The utility model relates to the technical field of compressor pistons, in particular to a high-pressure and large-piston-force reciprocating compressor piston.
Background
A piston part of the traditional reciprocating compressor adopts a mode of fixing a piston body and a piston sleeve by using screws and anti-loose gaskets, and the circumferential movement of the piston sleeve is restrained. If the pretightening force of the screw is not up to the standard in the normal maintenance stage of the equipment under the action of alternating force of the reciprocating compressor, the screw and the anti-loose gasket have the hidden trouble of detachment and fracture. The falling of the screw and the anti-loose gasket can cause the piston to strike the cylinder cover or the cylinder seat, which is a serious equipment safety event, so that development of a piston structure with high safety is needed.

Aiming at the defects of the prior art, the utility model provides a high-pressure and large-piston-force reciprocating compressor piston, which solves the problems that the existing piston sleeve is connected with a locking gasket by adopting a screw, and the hidden danger of falling and breakage is easy to cause.
In order to achieve the above purpose, the utility model is realized by the following technical scheme: the utility model provides a high pressure, big piston force reciprocating compressor piston, includes first half piston body, second half piston body, piston sleeve and piston rod, first half piston body with second half piston body suit in on the piston rod, piston sleeve both sides wall with pass through the pin connection between first half piston body inner wall and the second half piston body inner wall.
Preferably, the outer side of the piston sleeve is respectively sleeved with a supporting ring and a piston ring.
Preferably, a piston nut is arranged at one end of the piston rod, which is close to the front half piston body.
Preferably, the two side walls of the piston sleeve are connected with the inner wall of the front half piston body and the inner wall of the rear half piston body through pins.
Preferably, the piston sleeve is provided with mortise and tenon structures matched with each other between the front half piston body and the rear half piston body, and the piston sleeve is connected with the front half piston body and the rear half piston body through the mortise and tenon structures.
Advantageous effects
The utility model discloses a high-pressure and large-piston-force reciprocating compressor piston, which has the following beneficial effects:
1. The piston part does not use the traditional screw and anti-loose gasket fixing structure, only uses the pin to fix circumferentially, and solves the hidden trouble that the screw and the anti-loose gasket fall off and break under the long-time running condition of the high-pressure and large-piston-force reciprocating compressor.
2. The piston sleeve is fixed with the front half piston body and the rear half piston body, and the used pins are arranged inside the piston part, so that the hidden danger of pin falling is avoided.
