HI All,

Could someone help me resolve the excessive oil mist and droplet discharge from the oil reservoir breather of the Fram3 (GE MS3132) machine, with vapour and foam present in the oil reservoir and internal oil consumption?

Thanks in advance

Hi
Excessive oil mist and droplets from the GE Frame 3 (MS3132) breather are usually caused by oil foaming, contamination, overfilling, blocked mist eliminators, or worn seals. Check oil quality, reservoir level, breather condition, seal air pressure, and return lines to resolve the issue.

 

Hi,
Thank you for your reply. Yes, please. I want a technical and simplified version with technical arguments.

Thank you in advance.

Hi,
Here's a concise list of common causes with technical justifications for excessive oil mist from the GE Frame 3 (MS3132) breather:
Common Causes and Technical Justifications

1. Oil Foaming
   • Justification: Air entrainment during high-speed shaft rotation or from degraded anti-foam additives leads to unstable oil films and increased mist formation.
2. Oil Contamination
   • Justification: Water, fuel, or particulates reduce oil viscosity and increase volatility, promoting vapor and mist escape through the breather.
3. Overfilled Oil Reservoir
   • Justification: Excess oil height increases agitation and splashing inside the sump, resulting in mist carryover into the vent system.
4. Blocked Mist Eliminator or Breather Filter
   • Justification: A saturated or clogged filter reduces its ability to coalesce oil mist, allowing droplets to exit through the breather.
5. Worn or Damaged Shaft Seals
   • Justification: Worn carbon or labyrinth seals allow oil to leak into the air system, especially if seal air pressure is inadequate.
6. Low or Unstable Seal Air Pressure
   • Justification: Insufficient differential pressure (typically <1.5–2.5 psig above internal casing pressure) permits oil migration across seals into the vent line.
7. Restricted Oil Return Lines
   • Justification: Blocked or poorly sloped drain lines cause oil pooling, raising sump levels and mist generation due to oil accumulation.
