Understanding Bearing Housing Protection and Reliable
Two types of modern bearing protectors are now available: contacting face-seals, and rotating labyrinth seals. The payback period for a modern bearing protector, as compared to a lip seal, can be as fast as 4 or 5 weeks, after which it begins saving the equipment owner asmuch as $1,000 to $2,000 per year in avoided maintenance costs.

Leakage Characteristic of Helical Groove Seal Designed in
Helical groove seal is designed in reactor coolant pump to control the leakage along the front surface of the impeller face due to its higher resistance than the circumferentially grooved seal. The flow and the friction factors in helical groove seals are predicted by employing a commercial CFD code, FLUENT. The friction factors of the helical groove seals with helix angles varying from 20 ...

The Dangers of Overgreasing - Machinery Lubrication
Seal damage is another negative side effect of overgreasing. Grease guns can produce up to 15,000 psi, and when you overgrease a bearing housing, the lip seals can rupture, allowing contaminants such as water and dirt to gain access into the bearing housing. Keep in mind that lip seals usually fail around 500 psi.
Prevent seal contamination and failure with a reliable gas
Seal leakage is monitored, and the compressor is often shut down and vented when high leakage occurs, as this indicates a seal failure. To ensure the reliability of dry gas seals and prevent situations that lead to high seal leakage, the most important factor is the supply of quality gas to the seals when gas pressure is present or injected ...

PDF Design, Operation, and Maintenance Considerations for
The design of the bearing and seal cavities should consider prevention of lube oil migration into the gas seals. Lube oil will have a natural tendency to migrate along the shaft from the bearing to the barrier seal, requiring the bearing cavity to be designed to minimize the exposure of the barrier seal to lube oil. Flooded bearing drains
Two reasons why gearboxes leak
Labyrinth seals work best with a low sump-oil-level system (shown in yellow). The circled inset suggests that when the oil level is too high, labyrinth seals let oil escape. Labyrinth seals work best during operation but are susceptible to leaking when flooded with oil, especially at rest.
