TECHNOLOGICAL principle: ultrasounds, cavitation, implosion

Most of our systems consist of a stainless-steel tank fitted with an ultrasonic transducer activated by a high frequency generator. Parts to be treated are placed in a basket and immersed in the cleaning solution in the tank.

how does ultrasonic cleaning work?

how does ultrasonic cleaning work?


The signal emitted by the generator causes the transducer to create a high-frequency wave that travels through the liquid. This wave then produces successive variations of high and low pressure.

During the low-pressure phases, tiny bubbles appear in the liquid: this phenomenon is called cavitation.

During the high-pressure phases, the bubbles implode on contact with submerged surfaces, releasing the energy that created them. In addition, this mechanical energy increases the efficiency of the chemical action of the cleaning solution associated with it.

What is the difference between magnetostrictive, piezoelectric and multifrequency ultrasound?

Its basic principle makes magnetoelastic ultrasound is one of the oldest ultrasound technologies. However, in the past it was very inefficient.

Piezoelectricity was discovered later and this is very cheap and is also imported cheaply from Asia. This explains why many manufacturers turned to piezoelectricity.
