What is an Ultrasonic Generator? Company Overview And Catalog Of Blue Whale and Jie...
The central element of an ultrasonic cleaning system is the
ultrasonic generator, the source that provides the electrical
energy to the system's ultrasonic transducers. The job of
ultrasonic generator is to receive and convert energy from the
power source to the proper frequency, voltage, and amperage.
Electrical current from the power line is transmitted at
approximately 100 to 250 volts AC and a frequency of 50 or 60 Hz.
The majority of ultrasonic cleaning systems require the ultrasonic
generator to supply the ultrasonic transducer at a significantly
higher voltage and the specific frequency intended for the
ultrasonic cleaning system's operation.
Ultrasonic generator selection should be based on the specific
cleaning requirements of the application so that the best results
can be achieved. In addition to needing the power and frequency to
match the transducer requirements, the cleaning tank must be able
to accommodate the largest part to be cleaned. Additionally, the
power, frequency, and the tank size must be appropriate for the
type of contaminant and the mechanical strength of the parts
involved in the cleaning application.
Thanks to technological advances, ultrasonic generators are capable
of obtaining feedback from the transducers enabling them to
maintain maximum ultrasonic cleaning results by adjusting frequency
and power output. When necessary, ultrasonic generators can provide
customized variations in waveform, which optimizes the ultrasonic
cleaning capability, but at the same time decreases the likelihood
of parts damage during cleaning.
The proper frequency is essential for effective ultrasonic
cleaning. Low frequencies result in a cleaning solution with large,
active cavitation bubbles. Since the cleaning action produced by
low frequencies is more powerful, this method is best for sturdy
components that will not be damaged with hard surfaces that are not
susceptible to pitting. Mid-range frequencies produce smaller
cavitation bubbles resulting in a gentler cleaning action. The
highest frequency ranges are used for extremely delicate components
such as medical components and electronic components.
When ultrasonic cleaning is required for an individual process
involve the same types of parts, single frequency ultrasonic
generators are typically used. Multi-frequency ultrasonic
generators capable of producing numerous frequencies are also
available for facilities that require ultrasonic parts cleaning for
a variety of parts with differing characteristics.

How the Generator Works
An ultrasonic generator uses 60 Hz electrical utility power to
create frequencies ranging from about 20 kHz to the 1 MHz range.
Some models can generate only a single or a few frequencies while
others can produce a wide range. Different levels of power are also
available. For multiple-frequency models, operators can select the
frequency that is most appropriate for their cleaning application.
In addition to producing the high-frequency signal, ultrasonic
generators control the signal to maximize cleaning performance.
Generators may automatically adjust the signal to compensate for
heavy or light loading of the cleaning tank and they may “sweep”
the signal, varying the frequency slightly to eliminate resonance
or standing waves in the cleaning tank. For example, when a
generator is operating at 38 kHz, varying the frequency randomly
between 36 and 40 kHz eliminates hot spots and tank resonance that
could damage the parts to be cleaned.

How Do Ultrasonic Cleaners Work?
A simple way that ultrasonic cleaners work is likening them to an
automatic dishwasher, but with some added refinements. An automatic
dishwasher, much the same as an ultrasonic cleaner, combines water
and a detergent to remove grease, grime and other contaminants from
objects being cleaned.
Applications for ultrasonic cleaners include cleaning precision
optics and laboratory glassware. Instead of cleaning pots and pans
and bowls, ultrasonic cleaners most often are used to clean various
other metal and plastic products difficult or impossible to clean
by other methods.
Components of an Ultrasonic Cleaner
Tanks to hold the cleaning solution. Tanks should be of stainless
steel; their volume depends on the size of objects being cleaned
Ultrasonic transducers that create the cavitation and that are
bonded to the bottom of the tank
A generator to power the transducers
Controls that range from a simple on-off switch to sophisticated
microprocessors that govern cleaning time, sweep, pulse, degassing,
temperature, ultrasonic frequency , ultrasonic power, auto safety
shutoffs and other refinements. More on these below.
What Do Ultrasonic Transducers Do?
There are two basic types of transducers; piezoelectric (a.k.a.
electrostrictive) or magnetostrictive, but their function is the
same. They are excited by electric current provided by the
ultrasonic cleaner's generator to vibrate at ultrasonic frequencies
that cause the bottom (and sides as the case can also be) of the
tank to vibrate and thus serve as a membrane. This vibration forms
the vacuum bubbles that implode, (not explode) on contact with items in the ultrasonic cleaner
tank thereby blasting loose and carrying away contaminants. There
are also immersible transducers. Ultrasonic frequency is an
important part of how ultrasonic cleaners work and is discussed
next.
How to Choose an Ultrasonic Cleaner Frequency
Ultrasonic is typically defined as sound above the human range of
hearing. Low frequencies such as 25,000 cycles per second or 25 kHz
produce relatively large bubbles that implode more violently than
those created at higher frequencies such as 37, 80 or 130 kHz that
produce progressively gentle cleaning action. As an example, the
radius of a cavitation bubble produced at 37 kHz is approximately
88 microns. At 80 kHz it is 41 microns.
As a bit of digression, the implosion of cavitation bubbles produce
shock waves radiating from the site of the collapse and create
temperatures in excess of 10,000°F and pressures in excess of
10,000 psi at the implosion site. Yet the process is so fast that
there is little heat buildup and no damage to parts being cleaned.
That said, one should never reach into an operating ultrasonic cleaner to check, reposition or
remove parts for examination.
Removing gross contaminants from robust parts such as fabricated or
cast metals requires lower frequency cleaners. Softer metals,
plastics, and products with polished surfaces should be cleaned at
higher frequencies. In addition to protecting polished surfaces
smaller bubbles are better able to penetrate tight areas such as
seams, crevices and blind holes. If you'd like more information on
this particular topic check this article on selecting ultrasonic
cleaner frequencies.
Our point is that purchasing decisions for an ultrasonic cleaner
should be made on more than price.
