Factory Large Supply 60W 28KHZ PZT4 Piezo Ultrasonic Transducer for Washing

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.

The ultrasonic vibrator produced by our company is a piezoelectric ceramic conversion device, which converts high-frequency sinusoidal voltage signals into high-frequency mechanical vibration signals, which are installed on the bottom or side walls of the cleaning tank, and are transmitted through the tank and act on the cleaning medium. The vibration signal of the vibrator is converted into a cavitation effect, and the attachment of the object is quickly peeled off to achieve the purpose of cleaning.
The characteristics of the ultrasonic vibrators produced by the company include low heat generation, good thermal stability, low resonance impedance, good consistency between frequency and static capacitance, and complete and smooth waveforms of frequency and impedance.
Ultrasonic vibrators have multiple resonance points. Using the second and third resonance points of the vibrator, we have developed dual-frequency ultrasonic vibrators and three-frequency ultrasonic vibrators, which are effective in ultrasonic cleaning machines. The company can customize them according to your needs. Various types of ultrasonic vibrators can achieve a higher level of cleaning effect.
Our company always supplies frequency 17KHZ/20KHZ/22KHZ/25KHZ/28KHZ/33KHZ/40KHZ/53KHZ/60KHZ/80KHZ/100KHZ/120KHZ/200KHZ cleaning transducers.
Reference for frequency selection: low-frequency ultrasound (17-50KHZ) is suitable for most occasions or where the bonding strength of the dirt and the surface of the cleaning part is high, and high-frequency ultrasound (50-200KHZ) is suitable for the cleaning of precision parts. In order to achieve a more ideal effect, low frequency and high frequency ultrasound can be selected at the same time.

The vibrator produced by our company has low heat generation, good thermal stability, low resonance impedance, good consistency between frequency and static capacitance, and complete and smooth waveforms of frequency and impedance.
Working principle of broadband ultrasonic vibrator:
Ultrasonic waves are composed of a series of sparse and dense longitudinal waves, which propagate around through the liquid medium. When the sound energy is high enough, the attraction between the liquid phase molecules is broken during the loose half-cycle, forming a cavitation nucleus. The life of the cavitation nucleus is about 0.1 μs. It can generate a local high temperature and high pressure environment of about 4000 K and 100 MPa at the moment of explosion [6], and generate a micro jet with a speed of about 110 m/s with strong impact. This phenomenon is called Ultrasonic cavitation. The ultrasonic enhancement of the chemical reaction and transmission process is mainly caused by the chemical and mechanical effects of ultrasonic cavitation.
