CONTACT activated ANTI-WEAR COMPONENT

  • CONTACT activated ANTI-WEAR COMPONENT:

The contact activated Component is the first line of defense. This Component chemically bonds to metal surfaces upon contact and forms a thin extreme pressure barrier. The refrigeration oil, on the other hand, has no strong affinity for metal. No chemical bonding takes place. Since refrigeration oil is not attracted to metal, it can easily be wiped off or squeezed out under loads. Consequently, it offers little protection when hydrodynamic lubrication fails. Hydrodynamic lubrication failures occur during compressor start-up and shutdown, under extensive loads, or locally on rough bearing damage and accelerated equipment wear. Depending upon the compressor’s design, abrasive metal particles (suspended in the lubrication oil) can migrate throughout the machine and cause further damage.

 

The contact activated Component protects against damage incurred during hydrodynamic lubrication failure. This is possible because the Component is chemically bonded to the metal and is not easily removed. The extreme pressure barrier provides a lubrication cushion between two moving components to reduce metal-to-metal contact and surface wear. This bonding makes the protective barrier difficult to remove. In fact, it can only be removed with a powerful chemical or by mechanical means.
