Functioning
3 Functioning
Today, cleaning by ultrasound is the most modern fine cleaning
method.
The electric high-frequency energy created by an ultrasonic
generator is transformed into mechanical energy by piezo-
electrical transducer systems and is then transmitted into the
bath.
This process creates millions of tiny vacuum bubbles which
implode due to the variations of pressure caused by the
ultrasonic activity. Highly energetic liquid jets are created. These
jets remove dirt particles from surfaces and even from the
smallest grooves and bores.
3.1 Ultrasonic cleaning factors
Basically, the cleaning result depends on four factors:
Ultrasonic energy is probably the most important mechanical
factor in the cleaning process. This energy must be transmitted
through a liquid medium to the surfaces which are to be
cleaned.
The present Elmasonic unit is fitted with the innovative sweep
function device: electronic oscillation of the sound field (sweep
function) prevents the formation of zones of low performance in
the ultrasonic bath.
For saponification and removal of the dirt particles a suitable
cleaning agent is required. Elma has a large range of cleaning
media on offer.
Cleaning chemicals are also necessary to reduce the surface
tension. This increases considerably the efficiency of the
ultrasonic activity.
The effect of the cleaning medium is improved by the optimised
temperature of the cleaning liquid.
For Elma cleaning products please observe the instructions
given on the label or the product information leaflets.
The cleaning period depends on the degree and the kind of
contamination and on the correct selection of ultrasonic energy,
cleaning agent and temperature.
