Made In China High Quality 20KHZ Industry Ultrasonic Cleaning Transducer

Ultrasonic transducers are piezoelectric ceramics that resonate at ultrasonic frequencies and convert electrical signals into mechanical vibrations by the piezoelectric effect of the material. Medical ultrasonic transducers (ultrasonic probes) operate in much the same way, and typically contain an electrical energy storage element and a mechanical vibration system inside. When the transducer is used as a transmitter, the electrical oscillating signal sent from the excitation source will cause a change in the electric or magnetic field in the electrical energy storage element of the transducer, which changes the mechanical vibration system of the transducer through some effect. A driving force is generated to cause it to vibrate, thereby propelling the medium in contact with the mechanical vibration system of the transducer to vibrate and radiate sound waves into the medium. The process of receiving sound waves is exactly the opposite. External sound waves act on the vibrating surface of the transducer, causing the mechanical vibration system of the transducer to vibrate, causing an electric field in the energy storage element of the transducer or by some physical effect. The magnetic field changes accordingly, causing the electrical output of the transducer to produce a voltage and current corresponding to the acoustic signal.

Ultrasound vibrator, also known as ultrasonic vibrator, ultrasonic vibrator, is a kind of ultrasonic transducer, is the core component of the ultrasonic cleaning machine. Industry standard name: ultrasonic transducer, belongs to piezoelectric ceramic material, one of the main parts of ultrasonic cleaning machine. In terms of power, the single ultrasonic head is 60W and 100W. Frequencies are: 20KHZ, 25KHZ, 28KHZ, 40KHZ, 68KHZ, 80KHZ, 100KHZ, or higher respectively; from the shape difference is: straight column, horn, etc.

The ultrasonic cavitation threshold is closely related to the frequency of the ultrasound. The higher the frequency, the higher the cavitation valve.
In other words, the lower the frequency of the ultrasonic dishwasher, the easier it is to produce cavitation, and the longer the time interval between compression and thinning of the liquid at low frequencies, the bubbles can grow to a larger size before disintegration and increase. Cavitation strength is conducive to cleaning.

Therefore, low-frequency ultrasonic cleaning is suitable for places with large parts or a high degree of dirt and cleaning parts. However, it is easy to corrode the surface of cleaning parts, it is not suitable for cleaning parts with high surface finish, and the cavitation noise is large. At a frequency of about 40KHZ, at the same sound intensity, the number of cavitation bubbles is more than that at 20KHZ, and the penetrating power is strong. It is suitable to clean workpieces with complex shapes or blind holes. Cavitation noise is small, but cavitation Low strength, suitable for places where the binding force between the dirt and the surface of the object to be cleaned is weak.
