How to know if my ultrasonic machine works fine?

Ultrasonic cleaning equipment uses the cavitation phenomenon to remove traces of dirt from the surface of the part to be cleaned, therefore, to obtain a good cleaning result, it is essential to have good cavitation.

Cavitation depends fundamentally on:

It is important to perform a cavitation test to check the correct state of the bath. To do this, we will use a sheet of aluminum foil about 200mm long and 50mm wide that we will immerse in the bath with the ultrasound turned on at maximum power for about 30 seconds. If the result is good, we should obtain an image like the one in the sample. The absence of these small holes will denote that we do not have cavitation in the bathroom, so the results obtained in cleaning will not be favorable. On the contrary, if we obtain a sample with holes but they are large and poorly distributed, it will mean that we do have room but The bathroom conditions are not ideal.

To perform this test, it is recommended to have a temperature between 60ºC and 70ºC and to have degassed the bath.

What does it mean to degas the bath?

Degassing the bath means eliminating all the air dissolved in the bath. Ultrasonics are most effective when the bath is degassed. As long as there is air dissolved in the bath, all the ultrasonic power is used to eliminate this air in solution and not to make it fit. the liquid. For a unit of about 700 liters, it takes an average of 4 hours to degas the bath.
