This document discusses condition monitoring techniques presented by SKF India including vibration monitoring, oil analysis, temperature sensing, and ultrasound. It describes common machine types that can be monitored like motors, pumps, gearboxes, and turbines. Visual inspection, vibration analysis, oil analysis, ultrasound analysis, and temperature analysis are discussed as techniques. Specific potential issues that visual inspection could identify are outlined. Advantages of vibration analysis, ultrasound, and condition monitoring in general are presented as being non-contact, non-intrusive, able to work at a distance, portable, and providing convincing results.

– Ground straps intact/not frayed
– Coupling guards intact/no bolts
missing
– Inspection covers secured/no
bolts missing
– Seal steam leaks
– Piping steam leaks
– Transport pipe leakage
– Excessive, abnormal dirt
– Foundation/mounting problem
– Frayed wires
– Control box and switch
secure/so components broken

Lubricant Field Inspection
•Field inspection of lubricants can
include, among other techniques:
– Water contamination
(crackle test, free water,
etc.)
– Bottom sediment and
water
– Debris by patch test
– Viscosity changes
– Wear metals & ingress
debris
– Organic and inorganic
contaminants
