Cavitation refers to the formation of vapor bubbles within a liquid, caused by a drop in pressure. In pumps and plumbing systems, cavitation occurs when the pressure of the liquid falls below its vapor pressure, creating bubbles that collapse violently when they move to areas of higher pressure. This phenomenon can cause significant damage to pump impellers, valves, and pipes, leading to erosion, noise, vibration, and reduced efficiency. In severe cases, cavitation can cause system failure. To prevent cavitation, proper pump selection, correct system design, and maintaining adequate inlet pressure are essential. Engineers often use techniques like reducing pipe length, increasing pipe diameter, or adjusting pump speed to minimize the risk of cavitation.
