Description

Technical Field

[0002] Mechanical seals are devices used to prevent fluid leakage, mainly used in rotating fluid machinery, such as centrifugal pumps, centrifuges, reactors and compressors. It relies on at least one pair of end faces perpendicular to the axis of rotation. These end faces are kept in contact and slide relative to each other under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism, as well as the cooperation of auxiliary seals, so as to prevent fluid leakage.

[0003] Laser marking can produce various texts, symbols and patterns, and the character size can range from millimeters to micrometers with extremely high precision. At the same time, laser marking has a large degree of freedom in the material, shape, size and processing environment of the processing object, and is particularly suitable for automated processing and special surface processing, and can meet the needs of high-precision marking of seals in complex environments.
