High-performance sealing ring capable of achieving self-inspection after cracking

Abstract

The invention discloses a high-performance sealing ring capable of achieving self-inspection after cracking, and belongs to the field of sealing rings. The high-performance sealing ring capable of achieving self-inspection after cracking is characterized by comprising a fluorinated silicone rubber seal ring, wherein a sealing ring hollow cavity is dug in the fluorinated silicone rubber seal ring;a nano-carbon framework is arranged in the sealing ring hollow cavity and is fixedly connected with the sealing ring hollow cavity; a plurality of through holes are formed in the nano-carbon framework; the nano-carbon framework is internally filled with a plurality of balls No.1, and the plurality of balls No.1 are filled with a plurality of balls No.2, so that cracks which occur on the surface ofthe self-inspection sealing ring can be quickly found by a working staff through color development change visible to the naked eyes, and the cracks formed on the surface of the self-inspection sealing ring can be quickly repaired, a normal operation of the self-inspection sealing ring cannot be affected, so that the working performance of the self-inspection sealing ring on which the cracks formed on the surface are repaired can be greatly enhanced, and thus, the sealing ring still has the normal operation ability after the cracks occur for a while.

Description

technical field [0001] The invention relates to the field of sealing rings, in particular to a high-performance sealing ring capable of cracking and self-inspection. Background technique [0002] Sealing rings are mostly used for bearing sealing. Since the bearings are mostly rotating at high speeds, there are certain requirements for the wear resistance and high temperature resistance of the sealing rings. In order to reduce the wear of the bearing itself during work, the bearings often choose oil seals. A sufficient amount of lubricating oil is added between the bearing and the working room, which requires the sealing ring to have certain oil resistance and solvent resistance. Although the traditional rubber sealing ring needs better elasticity, it also has excellent wear resistance and high temperature resistance. , but its oil resistance and solvent resistance are poor, and it is difficult to adapt to the rubber sealing environment.

Problems solved by technology

[0004] Some sealing rings will have tiny cracks on the surface when they are working. These tiny cracks are difficult to observe with the naked eye of the staff, but these cracks will quickly tear and expand when the sealing ring is working, resulting in the failure of the sealing ring and seriously affecting the normal operation of the bearing. Work

[0005] Most of the existing self-test sealing rings excavate cavities in the sealing rings, and fill the cavities with liquid solvents. When the surface of the self-test sealing rings breaks, these liquid solvents will seep out from the cracks and react with air to solidify. It is simple and practical to prevent the fine cracks on the surface of the self-inspection sealing ring, and the staff can easily observe the repair traces of the self-inspection sealing ring through the color difference. However, during the self-repairing process of the self-inspection sealing ring, the cavity inside A small amount of liquid solvent seeps out to repair the cracks, resulting in a decrease in the strength of the self-test seal ring. Under the action of the bearing pressure, the self-test seal ring is easily deformed, which affects the sealing effect of the self-test seal ring
