OURS Produce 28KHZ 100W 120W  Ultrasonic Oscillator For Ultrasonic Cleaning Barbecue Dish

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.

Frequency selection

The transducer frequency is inversely proportional to the wavelength. The wavelength is related to the diameter of the bubble (strictly speaking, it is due to the low frequency of nucleation), and the bubble diameter is related to the explosion pressure. Generally, the higher the frequency, the smaller the wavelength, the smaller the bubble diameter, and the lower the explosion pressure, but the higher the bubble density and the better the permeability.

Based on the above principles:

Low frequency (17~23KHz): If the dirt to be cleaned is heavy or difficult to clean, and the impact of the explosion on the surface of the object to be cleaned is not great, the low frequency series transducer should be selected. Commonly used industries are: magnetic industry, auto industry, textile industry, etc. Note that this series is noisy and is best soundproofed.

Medium frequency (25~28KHz): If the dirt to be cleaned is slightly heavy or the cleaning is difficult, and the impact of the explosion on the surface of the object to be cleaned is not great, the medium frequency series transducer should be selected. This series of industries is the most widely used, common: mechanical processing industry, electroplating industry, catering industry and so on.

Medium and high frequency (33~60KHz): The medium and high frequency series transducers should be selected when the dirt to be cleaned is light, easy to clean, or when the impact of the explosion on the surface of the object to be cleaned is required. Commonly used industries are: precision parts, glass glasses, electronic components, circuit boards, etc.;

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