Description

Technical Field

[0001] The utility model relates to the technical field of mechanical sealing components, in particular to a mechanical sealing component with a protective structure. Background Art

[0002] A mechanical seal assembly is a device used to prevent a fluid (usually a liquid or a gas) from escaping or entering along the axial direction. Publication No. CN216045446U discloses a mechanical seal assembly with an anti-blocking function, comprising: a base; an end cover fixedly mounted on the right end of the base; a shaft rotatably mounted on the inner cavity side wall of the end cover; a stepped shaft arranged at the left end of the shaft; a moving ring assembly fixedly sleeved on the left end of the outer wall of the shaft, and the stepped shaft limits the moving ring assembly; a compensation mechanism arranged at the left end of the end cover, and the moving ring assembly limits the compensation mechanism. The mechanical seal assembly with an anti-blocking function effectively prevents small particles of grinding dust and broken grinding beads from entering the inner cavity of the anti-blocking assembly, improves the sealing effect, and prevents foreign particles from contaminating the medium and parts in the equipment, greatly extending the service life of the equipment. However, the rotating shaft of the sealing assembly generates heat during rotation. When the surface temperature of the sealing assembly is higher than the ambient temperature, air will form convection on the surface of the sealing assembly, thereby taking away part of the heat. However, the sealing component is not provided with a protective mechanism. In some working environments with a lot of dust, a large amount of dust will accumulate on the surface of the sealing component after a period of use, which may greatly reduce the heat dissipation efficiency and needs to be improved.
