The effect of mechanical seal fluid film (cushion pad):

In order to clearly illustrate the effectiveness of the fluid film (cushion pad), the Philips cartridge mechanical seal must calculate the time t for fluid extrusion when the gap is reduced from h1 to h2

Compare this time with the actual duration of the load. Even if the fluid film is compressed to the smallest gap, the time gap it experiences is still longer than the load action time, and the two surfaces will not be in direct contact, so there will be no wear of the sealing surface.
