what is tool cavitation
This video shows cavitation in a gear pump. Cavitation is the formation of vapour cavities in a liquid â i.e. small liquid-free zones (bubbles or voids) â that are the consequence of forces acting upon the liquid. It usually occurs when a liquid is subjected to rapid changes of pressure that cause the formation of cavities where the pressure is relatively low.
Cavitation - an Introduction. Cavitation occurs in fluid flow systems where the local static pressure is below vapor pressure. Cavitation is a common problem in pumps and control valves - causing serious wear, tear and damage. Under the wrong conditions cavitation reduces components life time dramatically.
