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
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
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
Thermography
• Periodically inspect electrical components and control cabinets
for heat related issues
• Assist shop personnel in troubleshooting suspect electrical
problems
• New equipment acceptance testing
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
Effects of Vibration on Equipment
Vibration Issues - Loop Pump
• Definition of resonance and demo
• Base resonance - causing vibration limits to be exceeded
during New Equipment Acceptance Testing
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
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.
Vibration Issues – Loop Pump
Vibration Issues w/ Sump Cover
• Resonance condition in sump cover causing premature
failure of pump bearings
