Industry Cleaning Company Supply Ultrasonic Transducer Different Frequency 40K/77K/100K/170K Ultrasonic Cleaning Transducer

Introduction to Ultrasonic Transducer

At present, piezoelectric transducers are mainly used in China because the transducers have high electroacoustic conversion efficiency, low raw material prices, and are easy to manufacture different structures to meet different cleaning requirements. Piezoelectric transducers are also available in a variety of shapes such as cylindrical, horn, etc. After comparison, the horn-shaped sandwich piezoelectric transducer is selected as the transducer.

  A transducer is a device used for energy conversion and is a device that converts one form of energy into another. In the field of acoustic research, transducers mainly refer to electroacoustic transducers, which can convert between electrical energy and acoustic energy.

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.
