Description

Technical Field

[0001] This utility model relates to the field of sealing technology, specifically to a ceramic sealing ring. Background Technology

[0002] Ceramic sealing rings are made of high-hardness ceramic material. Under high-speed and high-load working environments, they can maintain a low wear rate for a long time, extending the service life of equipment. When installing ceramic sealing rings, use a clean cloth or special cleaning agent to thoroughly remove oil, dust, burrs, and other impurities from the surface of the shaft or hole where the ceramic sealing ring will be installed. Carefully align the ceramic sealing ring with the mounting hole or shaft, ensuring that its position is correct and without deviation. Use an appropriate tool (such as a special press or soft metal rod) to gently press the sealing ring into the installation position. Be careful to apply pressure evenly and avoid excessive local pressure that may cause the sealing ring to break. Continue to push the sealing ring until it is fully in the installation position and fits tightly with the adjacent parts.

[0003] During actual installation, due to factors such as machining accuracy and assembly tolerance, there may be a tiny gap between the ceramic sealing ring and adjacent components. This tiny gap can cause leakage. Utility Model Content

[0030] 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.

[0031] The following is in conjunction with the appendix Figure 1-3 The embodiments of this utility model will be described in further detail.

[0032] Please see Figures 1-3 This embodiment provides a technical solution: a ceramic sealing ring, comprising: a ceramic sealing ring body 1, a groove assembly 2, a sealing ring 3, and an oil storage assembly 4;

[0033] The ceramic sealing ring body 1 is made of high-hardness ceramic material, which can maintain a low wear rate for a long time under high-speed and high-load working environment, thus extending the service life of the equipment.

[0034] The groove assembly 2 is set outside the ceramic sealing ring body 1, which enables the placement of the internal sealing ring 3 and oil storage assembly 4. The sealing ring 3 is sleeved on the outside of the groove assembly 2, and the material of the sealing ring 3 can be changed according to the medium being transported.

[0035] The oil storage component 4 is disposed inside the groove component 2. The oil storage component 4 includes a mounting positioning rod 401 disposed inside the groove component 2, a mounting fixing plate 402 integrally formed on one end of the mounting positioning rod 401, a spring 403 sleeved on the mounting positioning rod 401, a rubber ring 404 bonded to the mounting fixing plate 402 on one side, the other side of the outer wall of the rubber ring 404 being attached to the outer wall of the sealing ring 3, the rubber ring 404 having a cavity inside, a flow hole 406 opened on the rubber ring 404, and an annular baffle plate 405 integrally formed on the outer wall of the mounting fixing plate 402.

[0036] The groove assembly 2 includes a first annular groove 201, a circular groove 202, and a second annular groove 203. The first annular groove 201 is provided on the outer wall of the ceramic sealing ring body 1. The circular groove 202 and the second annular groove 203 are provided on the inner wall of the first annular groove 201. The second annular groove 203 is located on one side of the circular groove 202. A mounting positioning rod 401 is slidably connected inside the circular groove 202. The two ends of the spring 403 are respectively attached to the inner wall of the first annular groove 201 and the outer wall of the mounting fixing plate 402. The annular baffle plate 405 is slidably connected inside the second annular groove 203.

[0037] The implementation principle of this utility model of a ceramic sealing ring is as follows:

[0038] First, because the ceramic sealing ring body 1 has a groove assembly 2 on its outside, the groove assembly 2 can provide a place for the sealing ring 3 and the oil storage assembly 4.

[0039] Secondly, the sealing ring 3 can eliminate the gap between the ceramic sealing ring body 1 and the mounting component by being fitted onto the first annular groove 201 outside the ceramic sealing ring body 1. When the sealing ring 3 and the mounting component are pressed into contact, the sealing ring 3 will deform.

[0040] Finally, because the mounting positioning rod 401 can slide through the circular groove 202, the spring 403 on the mounting positioning rod 401 will press and push the mounting plate 402. During the displacement of the mounting plate 402, the connected rubber ring 404 can be driven to press against the deformed sealing ring 3. When the rubber ring 404 is compressed, the oil stored inside the rubber ring 404 will be released to the outside through the flow hole 406. At this time, the oil will wrap around the sealing ring 3, thus providing a longer service life for the oil-wrapped sealing ring 3. During the movement of the mounting plate 402, it can be moved synchronously inside the second annular groove 203 through the annular baffle 405, thereby protecting the internal spring 403 and other parts through the annular baffle 405.

[0041] 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.
