3. Mission Statement To communicate accurate information through the use of trend analysis, pattern recognition, statistical process analysis and device limit ranges to aid in increasing machine life cycle and machine availability.

4. Oil Analysis Affects on Machine Devices 1.Pumps 2.Oil tank 3.Flow control value 4.Pressure relief valve 5.Cylinders (counter balance) 6.Directional control valves 7.Throttle valve 8.Heat exchangers

5. Oil Analysis (cont.) What we measure Fluid Properties –Viscosity analysis –FTIR – Fourier transform infrared spectroscopy –Element analysis Contamination –Particle count –Moisture analysis –Patch Test Wear Debris –Wear debris density –Analytical ferrography –Elemental analysis

6. Vibration Analysis Periodically collect and analyze vibration data on machine tools and components Install remote collection boxes and permanent mount accelerometers Field balancing on fans and blowers In Shop balancing (Balance Stand) on fans, blowers and rotating components

7. Vibration Analysis (cont.) Laser shaft alignment on rotating equipment (except process pumps) Laser sheave to sheave alignment Acceptance Testing on new equipment and components Assist shop personnel in troubleshooting suspect bearing and alignment problems Ultrasonic testing

8. Thermography Periodically inspect electrical components and control cabinets for heat related issues Assist shop personnel in troubleshooting suspect electrical problems New equipment acceptance testing

9. Thermography (cont.) Aids in identifying bearing and coupling problems in rotating equipment Identify heat exchanger problems Identify problems in heating and cooling coils Identify insulation problems with ovens and furnaces Identify problems with oven and furnace door seals

10. Effects of Vibration on Equipment

11. Vibration Issues - Loop Pump Definition of resonance and demo Base resonance - causing vibration limits to be exceeded during New Equipment Acceptance Testing

12. Vibration Issues – Loop Pump First attempt to qualify new loop pump, concrete pad not adhered to floor Second attempt, resonant condition in pump base identified & eliminated by creating animation to identify flexing points Reasons for animation before adding gussets

13. Vibration Issues w/ Loop Pump First Attempt – Concrete not adhered to floor, noticed base moving during data collection. Contractors corrected by bolting concrete pad to concrete floor.

14. Vibration Issues – Loop Pump

15. Second Attempt – After flexing in pump base was identified with the help of the animation, contractors corrected by welding gussets in proper location.

16. Vibration Issues w/ Sump Cover Resonance condition in sump cover causing premature failure of pump bearings

17. Laser Alignment Shaft to Shaft

19. Laser Alignment Sheave to Sheave

20. Balance Stand Balance rotating components
