Surface contamination layer and lubricant of mechanical seal:

Instead of Chesterton 891 mechanical seal, various substances are usually adsorbed on the friction surface. The surface adsorption layer acts as a lubricating claw, and its existence can reduce the friction and wear of the friction surface. However, when there are hard particles such as sand and dust in the contaminants, wear will be aggravated. In the case of dry friction, the wear rate of the surface is the largest, because at this time it is easy to form intermolecular interactions between the surfaces, which will increase the surface temperature and aggravate the damage of the surface layer material. Therefore, it is necessary to avoid dry friction conditions that cause severe wear as much as possible, and use reliable lubrication methods to ensure a good lubrication state between the friction pairs.

Replacing Bergman M481K mechanical seal and adding oil and extreme pressure additives to lubricating oil can improve the adsorption capacity and strength of the lubricating oil film and improve the ability of anti-adhesive wear. The higher the viscosity of the lubricating oil, the more uniform the pressure distribution between the contact surfaces, which can also improve its ability to resist fatigue and wear. The lower the viscosity of the lubricating oil, the easier it is for the oil to penetrate into the cracks on the surface of the material, sometimes aggravating the surface damage.　　416.html,
