ultrasonic energy exists in a liquid as alternative rarefaction and compression of the liquid. During rarefaction, small vacuum cavities are formed which collapse, or implode, during compression. This continuing rapid process, called cavitations, is responsible for the scrubbing effect which produces ultrasonic cleaning 3 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. As the cavities form, they fill with unwanted air forming bubbles which resist collapse, and tend to remain suspended in liquid. These bubbles act as “shock absorber,” 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 applications.

frequency affects cleaning efficiency by determining the cavity size. Low frequencies such as 25khz 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. Frequency also affects degassing, with 40 khz nearly optimum. Ultrasonic energy is created within a liquid by means of transducers which convert electrical energy to acoustic energy,at the desired frequencies. All ultrasonic cleaning systems consist of 4 fundamental components:

1. Transducer

2. Generator

3. Tank

4. Cleaning liquid

the performance and reliability of the system depend upon the design and construction of the transducers and generators. The overall effectiveness of the cleaning is also dependent upon the cleaning liquid. The size of the tank is dependent upon the size or quantity of the parts being cleaned. The number of transducers and generators is determined by the tank size. The choice of cleaning liquid depends upon the parts being cleaned and contaminant to be removed.
