Ultrasonic Parts Washers
Ultrasonic parts washers work by inducing controlled cavitation in the cleaning fluid. Cavitation bubbles form and collapse suddenly, releasing tremendous energy against the surfaces of objects immersed in the tank. This action "scrubs" hard to remove soils from the parts. Cavitation is determined by the frequency of the unit. Low frequencies generate large cavitation and high frequencies generate smaller cavitation, but in greater numbers.
What is Ultrasonics?
The science of ultrasonics is the study and application of mechanical vibrations above the range of human hearing—typically greater than 18,000 HZ.
What is Ultrasonic Cleaning?
Ultrasonic cleaning uses ultrasonic energy in an immersion cleaning tank to assist in the removal of tenacious or stubborn soils from parts. An ultrasonic system always consists of at least three main components:
- A tank to hold the cleaning fluid and the dirty parts
- A generator to transform the line voltage into an ultrasonic signal
- Transducers to convert the ultrasonic electrical signal into mechanical energy
What is an Ultrasonic Generator?
The ultrasonic generator takes AC electrical energy from the power line and converts it to electrical energy alternating at the desired ultrasonic frequency. In addition, the ultrasonic generator may have complex circuitry which automatically tunes its output to the optimum operating frequency for the ultrasonic transducer.
What is an Ultrasonic Transducer?
A transducer converts electrical energy at the ultrasonic frequency to mechanical motion–sound. It directs the sound energy into the cleaning tank.
What is Cavitation and Implosion?
The phenomenon of cavitation is unique in fluids. The cavitation bubbles implode, releasing high energy locally. This implosion is the heart of the ultrasonic process.
How does Ultrasonic Cleaning Work?
An ultrasonic degreaser works by inducing controlled cavitation in the cleaning fluid. Cavitation refers to microscopic voids or "bubbles" that form when the transducers emit sufficient ultrasonic energy into the fluid. The cavitation bubbles form relatively slowly and then collapse suddenly, releasing tremendous energy against the surfaces of objects immersed in the tank that ‘scrubs’ hard to remove soils from the parts.
