25khz Piezoelectric Ultrasonic cleaning transducer for Cleaning of mechanical parts

UltraTecno has become an indisputable leader with more than 20 years dedicated to the sale of ultrasonic cleaning systems. We have specialized on ultrasonic cleaning systems for more than half a century, knowing first-hand the needs of our clients, developing our systems, and adapting them to their needs, while providing highly satisfactory results.  In this sense, we currently have more than twenty different models of ultrasound cleaners.  In addition, we rely on the possibility to design and manufacture all types of customized ultrasonic cleaning systems for all clients.

The transducers are devices that converts electricity into the movement that allows cavitation to take place.  In other words, transducers enable the cleaning of the part inside the tank.  Cavitation is a phenomenon from which millions of nanometric bubbles are generated and then compressed inside the liquid in the tank, imploding and releasing large amounts of energy.  When the energy collides with dirt, grease or dust adhered to the surface of the parts, it removes them without damaging the part, carrying out a cleaning process far beyond any other traditional system.

Ultrasonic Transducer classification:

A. piezoelectric chip classification: Black chip P4 series and yellow chip P8 series;

B. Frequency classification: low frequency series (17-23KHz), intermediate frequency series (25-28KHz), medium and high frequency series (33-60KHz) and high frequency series (68-200KHz);

C. Power classification: 30W series (including 35W), 50W series (including 60W), 100W series (including 80W) and other unconventional power;

D. shape classification: straight column and horn type

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.
