Cavitation is a phenomenon where vapor cavities form in a liquid due to rapid pressure changes. When these cavities collapse, they release energy in the form of shock waves, which can cause material erosion and damage. Cavitation is particularly problematic in systems with high flow velocities and pressure fluctuations, such as pumps and valves.
• Material Erosion: The collapse of vapor cavities can erode the surface of materials, leading to pitting and material loss.
• Noise and Vibration: Cavitation can produce significant noise and vibration, which can affect the overall performance and efficiency of the system.
• Reduced Efficiency: Erosion of filter materials can lead to increased pressure drop and reduced filtration efficiency.
