PRINCIPLES OF ULTRASONIC CLEANING
Ultrasonics is defined as a mechanical vibration above the
range of human hearing (i.e., above 18,000 Hz.). Ultrasonic
cleaning refers to the use of ultrasonic energy to assist in
the cleaning of soiled objects while they are immersed in a
cleaning fluid. Typical frequencies used in ultrasonic cleaning
are 20kHz, 25 kHz, 40 kHz, and 80 kHz.
Every ultrasonic cleaning system consists of three basic
components:
• An Ultrasonic Generator that converts 50 or 60 Hz electric
power form the electric utility supply to a high frequency
electric signal in the ultrasonic range.
• Ultrasonic Transducers to convert the ultrasonic electrical
signal into mechanical vibrations.
• A Tank with the ultrasonic transducers bonded to its exterior
and that contains the cleaning fluid and work pieces.

The tank is filled with a fluid suitable for the cleaning
application. When the ultrasonic generator is activated, the
transducers begin to vibrate at their natural frequency and
couple the ultrasonic energy into the cleaning fluid. If sufficient
energy is produced, the fluid molecules are pulled apart,
creating microscopic "voids" or bubbles. This phenomenon is
called cavitation. These cavitation bubbles increase and shrink
in size in step with the ultrasonic frequency. Above a certain
energy threshold, the bubbles will grow to an unstable size
and then suddenly collapse, releasing a tremendous amount of
energy into the fluid. If a soiled work piece is immersed in the
fluid, the cavitation bubbles will tend to collapse on the surfaces
of the parts. This creates a scrubbing action that literally
"blasts" away the contaminants from the parts.
