Actual contact area in mechanical seal application

In the application of mechanical seal, it is the sum of the micro contact area generated by the deformation of each micro convex body when the object is in contact. The contact of the rough surface is very discrete, and the actual contact area only accounts for a very small part of the nominal contact area. The actual contact area determines the range of the interaction force between the molecules of the rough surface, so the juice of it is the main component of the friction and wear analysis and calculation, which is extremely important.

The actual contact area increases as the load between the surfaces increases. This is due to more new contact spots. The size of the contact spots increases as the load increases, but due to the increase in the number of new smaller spots, the average size of the contact spots remains almost unchanged.　　344.html,
