Description

Technical Field

[0001] This utility model relates to the field of plunger technology, and in particular to a plunger with a plunger ring. Background Technology

[0002] A plunger is a mechanical component commonly used in equipment such as pumps, engines, and cylinders. Its main function is to move fluids or gases within a closed space through reciprocating motion. In hydraulic and pneumatic systems, plungers control the flow and pressure of fluids, thereby achieving power transmission. A plunger pump is an important device in a hydraulic system. It relies on the reciprocating motion of the plunger within the cylinder to change the volume of the sealed working cavity, thus achieving oil suction and pressure.

[0003] In the prior art, patent document with publication number CN202420680385.X discloses a wear-resistant plunger for a plunger pump, including a plunger body. The top of the plunger body is provided with an inclined portion, and the top of the inclined portion is provided with a spherical crown portion. A first locking block is fixedly connected to the outer side of the plunger body. A second locking block is engagedly connected to the outer side of the first locking block. A wear-resistant reinforcing tube is fixedly connected to the outer side of the second locking block. A threaded ring is provided on the outer side of the plunger body, and an inner spiral positioning ring is helically connected to the outer side of the plunger body.

[0004] To address the issue of pressure leakage caused by the plunger during oil pumping, which affects the working pressure of the plunger pump and makes maintenance difficult, the existing technology uses a wear-resistant reinforced tube and a threaded ring to finally position the wear-resistant reinforced tube, positioning it on the outside of the plunger body. This increases the wear resistance of the plunger body. However, this still results in the piston failing to provide cushioning during use, thus reducing the practicality of the plunger. Utility Model Content

[0005] In order to overcome the above-mentioned defects in the prior art, the present invention provides a plunger with a plunger ring.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a plunger with a plunger ring, including a mounting post, a connecting unit provided on the outer surface of the mounting post, a buffer unit provided on the outer surface of the connecting unit, the connecting unit including a sealing component provided on the outer surface of the mounting post and a connecting component provided on the outer surface of the sealing component, and the buffer unit including a buffer component provided on the outer surface of the connecting unit and an oil passage component provided on the outer surface of the buffer component.

[0007] Furthermore, the sealing assembly includes a plunger ring, the outer surface of which is fixedly connected to the outer surface of the mounting post, and three plunger rings are provided and evenly distributed on the outer surface of the mounting post.

[0008] Furthermore, the connecting assembly includes a connecting post, one end of which is fixedly connected to the outer surface of the mounting post, and the other end of which is fixedly connected to a piston.

[0009] By adopting the above technical solution, the installation of the plunger and the limiting of the plunger can be facilitated by the cooperation of the installation column, the plunger ring, the connecting column and the live plunger, thereby increasing the functionality of the plunger.

[0010] Furthermore, the buffer assembly includes a mounting base, one end of which is fixedly connected to the outer surface of the piston plunger. A groove is formed on the outer surface of the mounting base, and a connecting rod is fixedly connected to the outer surface of the mounting base.

[0011] Furthermore, an mounting plate is fixedly connected to the inner wall of the groove, and a plunger spring is fixedly connected to the outer surface of the mounting plate.

[0013] Using the above technical solution, during the use of the plunger, hydraulic oil can be delivered through the through hole on the outer surface of the oil ring, allowing the sealing ring to move under the limitation of the connecting rod and the sealing gasket. Then, the limiting block is used to assist in squeezing the limiting column, thereby driving the plunger spring to extend and retract inside the groove, thus playing a buffering role.

[0014] Furthermore, the oil passage assembly includes a second connecting post, the outer surface of which is fixedly connected to the outer surface of the piston, an oil passage ring is fixedly connected to the outer surface of the second connecting post, the outer surface of which has a through hole, and a connecting block is fixedly connected to the outer surface of which.

The connecting component includes a connecting post 3, one end of which is fixedly connected to the outer surface of the mounting post 1, and the other end of which is fixedly connected to a live plunger 4.

[0023] In this embodiment, when using the plunger, the plunger is first placed inside the cylinder by the cooperation of the mounting pin 1 and the plunger ring 2. The plunger's sealing performance can be increased by the plunger ring 2, and the length of the plunger can be increased by the cooperation of the connecting pin 3 and the live plunger 4.

A groove 7 is formed on the outer surface of the mounting base 5, and a connecting rod 6 is fixedly connected to the outer surface of the mounting base 5. A mounting plate 10 is fixedly connected to the inner wall of the groove 7, and a piston spring 8 is fixedly connected to the outer surface of the mounting plate 10. Two sets of mounting plates 10 are respectively fixedly connected to both ends of the piston spring 8. A limit post 9 is fixedly connected to the outer surface of the mounting plate 10, and the outer surface of the connecting rod 6... A piston 11 is slidably connected. A sealing ring 12 is fixedly connected to the outer surface of the piston 11. A sealing gasket 18 is fixedly connected to the outer surface of the piston 11.
