The Cavitation

Use of ultrasonic cavitation in cleaning

Ultrasonic cavitation cleaning is a technique that is increasingly used in industrial applications to achieve professional results.

The process involves creating turbulence within a liquid, which leads to the formation of bubbles (cavities). These bubbles contain high-pressure steam and implode, releasing energy in the form of steam pressure.

Specifically, the mechanical vibrations produced by the PZT elements attached to the walls of the tank generate waves in the liquid. These waves alternate between a compression phase and a subsequent decompression phase, creating a strong turbulence.

Consequently, many cavitation bubbles are formed, which when imploded develop a pressure that was measured around 1,000 bar. The more compression and decompression action the more energy is.

Any foreign body present on the surface of a piece immersed in the liquid is crushed, dissolved and removed. It is a well-known and much-feared phenomenon in the field of naval engineering. This occurs due to the corrosion caused by the cavitation generated by the violent swirling of propellers, requiring specific measures to prevent it.

On the contrary, in the field of ultrasonic cleaning, cavitation plays an essential role in removing surface dirt that lodges in the inner parts of an object.
