[0002] During pump operation, the sealing ring is one of the key components, and its sealing performance directly affects the pump's efficiency and service life. Traditional pump sealing rings, after prolonged operation, are prone to frictional wear between the sealing surfaces due to a lack of effective lubrication. This leads to decreased sealing performance, leakage, and other problems, increasing equipment maintenance costs and operational risks.

[0003] To address the aforementioned issues, we propose a pump sealing ring with self-lubricating properties. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 , Figure 2 , Figure 3 This utility model provides a technical solution: a pump sealing ring with self-lubricating function, including a sealing ring body 1, a self-lubricating circulation pipe 2, a flow accumulation isolation structure 3, and an auxiliary sealing ring 4.

[0026] The sealing ring 1 has a flow-accumulating isolation structure 3 near the top on its outer circumference. The self-lubricating circulation pipe 2 is located in the ring wall interlayer of the sealing ring 1. The self-lubricating circulation pipe 2 is coiled around the circumference of the sealing ring 1. One end of the self-lubricating circulation pipe 2 has a first pipe opening 21, and the other end has a second pipe opening 22. The first pipe opening 21 is located on the outer circumference of the sealing ring 1 near the flow-accumulating isolation structure 3, and the second pipe opening 22 is located on the outer circumference of the sealing ring 1 near the bottom. The outer circumference of the sealing ring 1 has an annular groove, and the auxiliary sealing ring 4 is located in the annular groove of the sealing ring 1.

[0027] The self-lubricating circulation pipe 2 needs to be filled with lubricating medium in advance, and both the first pipe port 21 and the second pipe port 22 can realize the inflow and outflow circulation of lubricating medium.

[0028] Furthermore, the flow accumulation isolation structure 3 includes a flow accumulation baffle ring 31, an isolation convex ring 32, an isolation groove 33, and a flow guiding cavity 34.

[0029] The flow accumulation baffle ring 31 is disposed on the outer side of the circumference of the sealing ring body 1. The inner sidewall of the flow accumulation baffle ring 31 and the outer side of the circumference of the sealing ring body 1 form the isolation groove 33. An isolation protrusion ring 32 is provided on the outer side of the circumference of the sealing ring body 1 within the isolation groove 33. The flow guiding cavity 34 is provided in the ring wall interlayer of the sealing ring body 1. One end of the flow guiding cavity 34 is connected to the isolation groove 33, and the other end of the flow guiding cavity 34 is connected to the stepped groove on the inner bottom surface of the circumference of the sealing ring body 1.

[0030] When an external medium enters the flow-accumulating isolation structure 3, most of the external medium initially accumulates in the isolation groove 33. Solid impurities in the external medium are isolated at the bottom of the isolation groove 33 by the isolation convex ring 32, while the liquid portion of the external medium flows into the stepped groove on the inner circumference of the sealing ring 1 through the guide cavity 34. It should be noted that the guide cavity 34 is a pipe type, and multiple guide cavities 34 are evenly distributed on the outer circumference of the sealing ring 1, facilitating the flow of the liquid portion of the external medium. This has been described in the prior art and will not be repeated here, nor is it a core protection point of this application.

[0031] Furthermore, the auxiliary sealing ring 4 includes a connecting ring body 41, a sealing strip 42, and a folded sealing ring 43.

[0032] The connecting ring 41 is fitted into the annular groove of the sealing ring 1, and the sealing strip 42 and the folded sealing ring 43 are provided on the outer circumference of the connecting ring 41.

[0033] Furthermore, a lubrication groove is formed between the inner wall of the folded sealing ring 43 and the outer circumference of the connecting ring 41.

[0034] As shown in the appendix Figure 3 As shown, when the folded-back sealing ring 43 is in the folded-back state, it can roll the lubricating medium into the lubrication groove between the inner wall of the folded-back sealing ring 43 and the outer circumference of the connecting ring 41.

[0035] Furthermore, an auxiliary flow-limiting ring 5 is provided near the bottom on the outer circumference of the sealing ring body 1. The inner wall of the auxiliary flow-limiting ring 5 forms an auxiliary flow-limiting groove with the outer circumference of the sealing ring body 1. The auxiliary flow-limiting ring 5 needs to be positioned close to the second pipe opening 22 to gather the lubricating medium near the second pipe opening 22, promoting the overall self-circulation effect. Combined with the folded-back sealing ring 43, this further ensures that the lubricating medium is retained on the outer circumference of the sealing ring body.

[0036] As attached Figure 1 As shown, the outermost circumferential diameter of the flow-accumulating baffle ring 31 is larger than the outermost circumferential diameter of the sealing strip 42, the outermost circumferential diameter of the folded-back sealing ring 43, and the outermost circumferential diameter of the auxiliary flow-limiting ring 5. This ensures that the outermost end of the flow-accumulating baffle ring 31 forms a cavity with the external device, allowing the lubricating medium to circulate within this cavity.

[0037] The lubricating medium is present in the self-lubricating circulation pipe 2, and both the first pipe port 21 and the second pipe port 22 can discharge or enter the lubricating medium. Because the outer casing structure of this utility model will rotate, the internal lubricating medium will flow.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
