Case Study - Oil Analysis , A Powerful Tool For Maintenance

A good doctor prescribes only after proper diagnosis likewise a maintenance person monitors all the vitals of his machine. Plant-wide reliability is achieved by proactively monitoring various indicators of oil.

By analyzing oil-following are accomplished:-

When your machines are going to fail?

Early detection of incipient machine failures?

When an oil change is required?

A better understanding of contamination levels?

Optimizing machine reliability at the lowest possible cost?

THREE CATEGORIES OF OIL ANALYSIS

WHAT IS ANALYSED

FLUID PROPERTIES

CONTAMINATION

WEAR DEBRIS

Physical and chemical properties of used oil

Fluid and machine destructive elements

Presence and identification of wear particles

VISCOSITY-REFERENCE LIMITS

How to set viscosity Limits

Viscosity
  • *Twice this amount for oils with VI improvers 
  • **Crankcase  of limits  based on cSt @100*c  ; industrial oil based on cSt @ 40*c 

        Note : Severe  Environment oils are at high risk for  thermal and oxidative degradation .

Summary

  • Know which questions you are trying to answer
  • Know what the tests can tell you and how they can answer your questions
  • Don’t neglect the other oil analysis checklist items.
  • Always ensure all the machine and lubricant data is on the report
  • Always ensure relevant historical data is reported, such as top- ups or failures.
  • Always keep a new oil baseline for references
  • Sample routinely and optimize the frequency
  • Know the three categories of oil analysis, how they influence each other and their significance
