What is cavitation and cavitation phenomenon?

What is cavitation and cavitation phenomenon? In the selection and usage of slurry pumps, we often hear a term called “cavitation”. So what is cavitation? Here, Pan Shi Pump Industry will briefly introduce the term “cavitation”.

When a liquid reaches a certain temperature and the pressure decreases to the vaporization pressure at that temperature, a large amount of vapor will be released from the liquid and mix with air, forming many small bubbles. This is called “cavitation”. When these bubbles reach the high-pressure zone, they will collapse, creating a local vacuum. If the bubbles collapse on a metal surface, they will impact the surface with significant force, causing damage to the metal and generating vibration. This phenomenon is known as “cavitation phenomenon”.
