Cavitation refers to the formation and subsequent implosion of vapor bubbles in a fluid. This phenomenon typically occurs in hydraulic systems when the pressure in a local area drops below the vapor pressure of the fluid, leading to the creation of vapor bubbles. When these bubbles travel to a region of higher pressure, they collapse or implode violently, which can cause significant damage to hydraulic components, such as pumps and valves.

Understanding cavitation is crucial because it can lead to performance issues and premature failure of hydraulic equipment. Proper design and operation of hydraulic systems aim to maintain pressures above the vapor pressure of the fluid to minimize the risk of cavitation, ensuring the system operates efficiently and reliably. This makes it essential for those working in hydraulic systems to recognize the implications of cavitation and to implement measures to prevent it.
