Why Oil Analysis?

1. Why Oil Analysis? Are you ready to implement an effective Oil Analysis Programme?

2. Wear & Tear in Oil Systems • The condition of the oil will determine the life of components. • Surface clearances are typically 2-5 microns; any solid contaminants larger than the clearance will cause damage • Remove and try to reduce contaminant generation • Reduced contaminant levels will improve the life expectancy of both the components and the oil • Chemical and Water contamination also contribute to component and oil degradation SFR GB Limited

5. Target Cleanliness Goal-Based Limit Setting • British Hydromechanics Research Association (BHRA) • Controlled “field” study of hydraulic machines • 117 hydraulic machines • Injection moulding • Machine tools • Material handling • Mobile equipment (e.g. earth moving) • Marine hydraulics • Test stands • Period : 3 years • Purpose: Correlate fluid cleanliness to breakdown frequency Arbitrary base

6. Oil Pump or Dirt Pump? At ISO 21/18, this hydraulic system passes 136 50-lb. bags of dirt through the teeth of the pump in 1 year. pounds of dirt filter performance (A) passing through nominal - beta > 5 pump/year (C) absolute - beta > 75 All figures are approximations. At ISO 14/11, only one 50-lb. bag of dirt passes through the pump.

8. Oil Cleanliness based on ISO 4406 SFR GB Limited

9. “70% of hydraulic component failures are due to the condition of the oil. Of these oil related failures, 40% are directly related to oil quality and 60% are related to oil cleanliness”. Shell Lubricants “6-7% of GDP is required to fix the damage caused by mechanical wear” Prof E. Rabinowicz USA SFR GB Limited

10. Reliability is determined by the maintenance strategy SFR GB Limited

13. Why an Oil Analysis Programme with SFR? • Core Business • Programme Benefits • Management SFR GB Limited

14. Core Business • No vested interest in selling oil or components. • Our objective is to reduce your costs. • Knowledge of wear and tear in lube systems and amount of damage caused by varying levels of contamination. • Wholly Independent SFR GB Limited

15. Benefits of Oil Analysis • Provides data on the operating condition of the equipment. • The analysis results not only establish the condition of the oil but will also establish the condition of the equipment. • Enables a predictive strategy to be adopted • Predictive - Actions performed in an attempt to predict/foresee a developing problem by providing systematic analysis. • Enables a proactive strategy to be adopted • Proactive - Actions performed in an attempt to rectify a developing or existing problem by providing root cause analysis and diagnosis. • Measurably Extend Life of Oil • Measurably Extend Life of Equipment • Increase Production/Machine Availability • Reduce Maintenance Spend • Reduce Breakdowns SFR GB Limited

16. SFR Management of Oil Analysis • Set sample frequencies for each unit • Set targets for oil cleanliness and wear debris levels • SFR engineers available to assist in taking samples throughout the year • Monthly payments for easier management of budgets • Free access to your results via a website with facility to track and trend results • Regular follow up meeting to discuss the results and recommendations and address any on-going issues • Provide of a summary 'Action Sheet' to highlight any issues and save you having to trawl through each individual result.
