Preventing Ingress Contamination by Providing Bearing Cavity Pressurization 

This presentation relates to bearing cavity protection where the bearing cavity may be submerged underwater or operates in a harsh environment. What we will discuss is the prevention of ingress contamination by means of: (1.) Hermetically sealing the bearing cavity; (2.) Pressurizing the bearing cavity with low air or nitrogen; (3.) Controlling the pressure in the bearing cavity 24/7; (4.) Giving a visual and physical indication of the amount of pressure; (5.) Indicate bearing cavity integrity 24/7. For an attendee that has current contamination issues and has tried everything, this presentation will give them an alternative method to prevent ingress contamination with indication of bearing cavity integrity 24/7.
