Induction of ultrasonic cleaner
Ultrasonic energy exists in a liquid as alternate rarefactions and compressions of the liquid. During rarefaction, small vacuum cavities are formed which collapse, or implode, during compression. This continuing rapid process, called cavitation, is responsible for the scrubbing effect which produces ultrasonic cleaning. Three factors affecting the scrubbing action are the degree of liquid degassing, the ultrasonic frequency and the chemical characteristics of the liquid at specific temperatures.
Degassing is the removal of unwanted air from the liquid, typically found in fresh tap water. As the cavities form, they fill with the unwanted air forming bubbles, which resist collapse and tend to remain suspended in the liquid. These bubbles act as "shock absorbers," which materially reduce cleaning efficiency. The amount of air can be reduced by periodically switching off, or modulating, the sound energy to permit adjacent bubbles to coalesce, float to the surface, and escape. The type of modulation is important, for the correct balance between degassing and cleaning efficiency must be selected for each cleaning application.
Frequency affects cleaning efficiency by determining the cavity size. Low frequencies generate large but relatively few cavities with high cleaning power. High frequencies generate a great number of small cavities with good penetrating capability. The selection of the correct frequency is difficult, for it varies with each cleaning application.
The frequency also affects degassing, with 40 kHz nearly optimum.
Cleaning efficiency is also affected by the chemical and physical characteristics of the liquid. For best cleaning, the liquid must chemically soften the soil, yet maintain effective cavitation and provide the desired characteristics for rinsing and drying the cleaned parts. Ultrasonic cleaning solutions are broadly characterized as aqueous or non-aqueous. Final selection is dependent upon the overall process considerations for the cleaning application
