1
Cavitation

• The formation and collapse of vapor bubbles in a
  liquid.

2
Results From Cavitation in Pumps

• Vibration and Shaft Deflection
• Bearing Failure
• Packing or Seal Leakage
• Major Erosion
• High Noise Levels

3
Cavitation in Valves and Piping

• Packing or Seal Leakage
• Major Erosion
• Produces High Noise Levels
• Easily Detectable

4
Detection and Severity

• Detection
• Normal low level flow noise increases with
  bursting.
• Bursting(events) are random and contain high
  frequency energy.

5
Severity

• Damaging
• Signal to noise ratio increases to 5/1 or
  greater.
• Repetition rate is more than 2 events per/second
