Wear forms and characteristics of mechanical seals

One of the important phenomena associated with friction between mechanical seals is wear, that is, damage caused by friction. Broadly speaking, the process of continuous damage or residual deformation due to the relative movement of the surface is called wear. When assessing the life of mechanical seals, the damage forms such as abrasion, corrosion, fatigue, thermal cracking, erosion, and aging are all regarded as wear. In fact, the abrasion of the sealing surface is a complex process including abrasion, corrosion, fatigue, erosion, etc. at the same time. Wear and tear is not only the main reason for material consumption, but also an important factor affecting the service life of the machine. In order to extend the life of the seal, it is necessary to understand the wear mechanism, law, influencing factors and wear rate.　　378.html,
