Introduction to Ultrasonic Transducers
Ultrasonic vibrator, also called ultrasonic vibrator, ultrasonic vibrator, is a kind of ultrasonic transducer and the core component of ultrasonic cleaning machine. We call the whole of ultrasonic transducer and horn connected as vibrator. Ultrasonic transducer is one of the important components in the ultrasonic cleaning machine and ultrasonic vibration plate, which largely determines the quality of the ultrasonic effect.
Our company provides professional ultrasonic transducers with stable quality, high efficiency output and moderate price based on many years of ultrasonic cleaning experience, combined with the opinions and feedback of users.
Ultrasonic transducer is a device that converts high-frequency electric energy into mechanical vibration. The high-frequency electric energy input by the ultrasonic generator matches the piezoelectric ceramic sheet with the resonance frequency of the ultrasonic transducer. The electric energy is converted by the piezoelectric effect of the material. Converted into mechanical vibration, that is, ultrasonic vibration, is transmitted to the water medium through the ultrasonic transducer, forming negative pressure bubbles and shock waves in the water, and transmitted in the tax-based solution to achieve the effect of cleaning the surface of the workpiece. The transducer is mainly composed of aluminum block, piezoelectric ceramic sheet and insulating layer.
Ultrasonic vibrators (ultrasonic transducers) such as 28KHZ/40KHZ/25KHZ/68KHZ/80KHZ/120KHZ/200KHZ are widely used in electronics, machinery, automobiles, electroplating, chemical fiber, optics, bearings and other industries. Such as cleaning magnetic cores, oil nozzles, auto parts, electroplating hardware tools, chemical fiber spinnerets, optical lenses, bearings, tools, tableware, medical equipment, precision hardware, watch parts, gold and silver jewelry, electronic components. The frequency vibration is strong and the density is uniform. It can quickly achieve the purpose of degreasing, sodium removal, decontamination and descaling. In addition, it can also be used in chemical experiments to achieve catalysis, stirring, and rapid generator chemical reactions. Wait.

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.
