Ultrasonic Transducer

The mechanism of ultrasonic cleaning is to make use of the physical effects such as cavitation, radiation pressure and sound flow in the cleaning liquid. It can exfoliate the machinery produced by the dirt on the cleaning parts, and can also promote the chemical reaction between the cleaning liquid and the dirt, so as to achieve the purpose of cleaning the object. The frequency of the ultrasonic cleaning machine can be selected by 10~500 kHz according to the size and purpose of the cleaning material, generally more than 20~50 kHz. With the increase of the frequency of ultrasonic transducer, Langerhans oscillator, longitudinal oscillator and thickness oscillator can be used. In the miniaturization aspect, radial vibration and flexural vibration are also adopted. Ultrasonic cleaning has become more and more widely used in various industries, agriculture, household equipment, electronics, automobile, rubber, printing, aircraft, food, hospital and medical research.

Ultrasonic Transducer Frequency selection

The frequency of the transducer is inversely proportional to the wavelength, and the wavelength is related to the diameter of the cavity (strictly speaking, the nucleation time is longer due to the low frequency), and the diameter of the cavity is related to the explosion pressure. The higher the general frequency, the smaller the wavelength, the smaller the diameter of the cavity, the lower the explosion pressure, but the higher the density of the cavity, the better the permeability.
Based on the above principles:
Low frequency (17 ~ 23KHz): When the dirt of the cleaned material is heavy or difficult to be cleaned, and the explosive impact does not cause much damage to the surface of the cleaned material, the low frequency series transducer should be selected. Commonly used industries are: magnetic industry, steam protection industry, textile industry and so on. Note that the noise of this series is large, preferably sound insulation.

Medium frequency (25 ~ 28KHz): If the dirt of the cleaned material is slightly heavy or the cleaning is difficult and moderate, and the explosive impact does not cause much damage to the surface of the cleaned material, the intermediate frequency series transducer should be selected. This series of industries are the most widely used, and are common in machinery processing industry, electroplating industry, catering industry and so on.

Medium and high frequency (33 ~ 60KHz): When the dirt of the cleaned material is light, the cleaning is easy, or the explosive shock damage to the surface of the cleaned material is required, the medium and high frequency series transducer should be selected. Commonly used industries include precision parts, glass glasses, electronic components, circuit boards, etc.

High Frequency (68-200KHz): The dirt is very light and easy to clean. When the explosive impact is prohibited to damage the surface of the cleaned object, the high frequency series transducer should be selected. Commonly used industries are semiconductors, special high-precision parts, etc.
