Mechancal seals grainding and polishing

We often encounter deformation of the mechanical seals sealing faces friction pair in the maintenance of equipment seals. In order to ensure the flatness of the seal faces, we need to perform grinding and polishing. Grinding and polishing processes generally use abrasives, abrasive fluids, and tools to grind and polish the surface of the dynamic and static sealing rings sealed at the time to obtain a predetermined shape and surface roughness. It is a high-precision machining method and a machining method as a high-hardness material. The flatness of the surface mechanical seal sealing faces friction is high, and the roughness is small. It is difficult to achieve it by ordinary processing methods, so it needs to be solved by grinding and polishing
 
Grinding and polishing process is to contact the mechanical seal surface of the workpiece with the grinding tool, add abrasives between the two, and remove the extremely thin surface layer from the work surface during the movement to obtain a high-precision surface. Grinding and polishing improves the organization of the working face of the seal ring and provides a wear-resistant surface for the seal. Its functions are:
Reduce the friction coefficient,
Surface strength has been improved accordingly
Improve corrosion resistance
The surface is beautiful. It can improve the surface reflection coefficient, and it is easy to detect the flatness by optical flat crystal. Grinding and polishing improves the organization of the working end face of the mechanical sealing ring, and provides a wear-resistant surface for the mechanical seals. Its role is to reduce the friction coefficient, increase the surface strength accordingly, improve the corrosion resistance, and improve the surface reflection coefficient. , It is easy to detect flatness with optical flat crystal.
