The influence of friction surface temperature of mechanical seal:

Replace the AES CSS IC mechanical seal friction surface temperature on the wear, there are two main aspects: change the characteristics of the friction material, affect the formation of surface adhesion film and change the characteristics of the surface lubricant.

Material hardness decreases with increasing temperature. At high temperatures, the rough bumps on the surface are prone to deformation and adhesion, reducing the hardness and increasing wear. Therefore, heat-resistant materials should be used to make parts under high temperature conditions. Under normal environmental conditions, most metal surfaces are covered with an oxide film. The correct shape and order of the film depends on the temperature at which the film is formed. The higher the temperature, the more complete and thicker the film.

The increase in temperature between the surfaces will oxidize the lubricating oil on the surface, which may lead to lubrication failure. Under high temperature working conditions, the use of cyclic reciprocating lubrication and the use of high-temperature lubricants, such as graphite and molybdenum disulfide, should be considered.　　415.html,
