The friction characteristic of the mechanical seal is used to distinguish the friction state of the seal

The friction characteristic of the mechanical seal can also be used to distinguish the friction state of the seal. The friction characteristic used to determine the friction state is called the Stribeck curve in tribology. 1 is the turbulent flow zone, and 2 is the laminar flow zone. 3 is the liquid lubrication (thick film lubrication) zone, where the ratio of the fluid film thickness to the surface roughness (film thickness ratio) is larger, and the mixed lubrication zone (dotted line) of fluid lubrication and boundary lubrication is in this zone. A bump may touch. Elastic fluid lubrication or partial elastic fluid lubrication (thin film lubrication) area. The boundary lubrication zone, where the film thickness is very thin, will cause solid contact. Mixed lubrication zone of boundary lubrication and solid friction (dotted line). The solid friction zone may completely lose the carrying capacity of the liquid film.　　377.html,
