25K/40K/80K Multi Frequency High Efficient Ultrasonic Cleaning Vibration For Electroplating Factory

The transducer vibrator converts the high-frequency excitation current into ultrasonic vibration, which is the driving part of the sandwich piezoelectric ceramic transducer. The performance of the entire transducer system depends largely on the quality of the transducer oscillator. When designing and manufacturing a low-frequency sandwich piezoelectric ceramic transducer, the transducer vibrator must be designed first. The frequency of the vibrator ultimately determines the frequency of the sandwich Yaodan ceramic transducer.

There are two types of transducers used for ultrasonic cleaning. One is a magnetostrictive transducer, and the other is a piezoelectric transducer. The electroacoustic efficiency of the magnetostrictive transducer is relatively low. Moreover, the metal nickel material is expensive and the manufacturing process is complicated, so it is rarely used at present. There is also a magnetostrictive transducer made of ferrite material. Although its electro-acoustic efficiency is relatively high, its mechanical strength is low, and the electric power capacity it can withstand is small, so it is rarely used in my country at present.

At present, our country mainly adopts piezoelectric transducer, because this kind of transducer has high electro-acoustic conversion efficiency, low raw material price, and easy to manufacture different structures to meet different cleaning requirements. There are many kinds of piezoelectric transducers, such as cylindrical and horn-shaped. After comparison, it is determined that the horn-shaped sandwich piezoelectric transducer is selected as the transducer for this time.

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

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.
