What is cavitation in SAP PM-PDM-VA - Vibration Analysis?

SAP Term: cavitation

• Component: PM-PDM-VA

• Component Name: Vibration Analysis

• Description: A condition where the inlet pressure of a pump or water turbine is too low and therefore causes a mixed flow of fluid and vapor. Cavitation causes random high frequency vibration.

• Key Concepts: 
  Cavitation is a phenomenon that occurs when a liquid is subjected to a pressure drop, causing the formation of vapor-filled cavities. In the context of vibration analysis, cavitation is the formation of bubbles in a liquid due to the vibration of a machine. This can cause damage to the machine and its components, as well as reduce its efficiency. 
  
  How to use it: 
  In order to detect cavitation in a machine, vibration analysis must be performed. This involves measuring the vibration of the machine and analyzing the data to identify any abnormal patterns or frequencies that could indicate cavitation. If cavitation is detected, corrective action must be taken to prevent further damage or loss of efficiency. 
  
  Tips & Tricks: 
  It is important to regularly monitor machines for signs of cavitation, as it can cause significant damage if left unchecked. Additionally, it is important to ensure that all machines are properly maintained and lubricated in order to reduce the risk of cavitation. 
  
  Related Information: 
  Cavitation can also occur in other contexts, such as in pumps and hydraulic systems. It is important to understand how cavitation can affect these systems in order to prevent damage and ensure optimal performance.
