20MM Diameter Ceramic 40Khz 200W Ultrasonic Welding Piezoelectric
Transducer
Description:
The ultrasonic transducer mainly comprises a casing, an acoustic
window (matching layer), a piezoelectric ceramic disk transducer, a
backing, an extraction cable, a receiver and the like. Among them,
the piezoelectric ceramic disk transducer plays the same role as
the general transducer, and is mainly used for transmitting and
receiving ultrasonic waves; and on the piezoelectric ceramic disk
transducer is a receiver, mainly by the outgoing cable The
transducer, the metal ring and the rubber gasket are used as an
ultrasonic receiver to receive the Doppler echo signal generated
outside the band of the piezoelectric ceramic disk transducer.

The following mainly describes the role of the ultrasonic
transducer.
1, ultrasonic cleaning
The mechanism of ultrasonic cleaning is to use the physical effects
such as cavitation, radiation pressure and sound flow when the
ultrasonic wave propagates in the cleaning liquid, to peel off the
mechanical phenomenon generated by the dirt on the cleaning member,
and at the same time to promote the chemical reaction between the
cleaning liquid and the dirt. Reaction, to achieve the purpose of
cleaning the object. The frequency used by the ultrasonic cleaner
can be selected from 10 to 500 kHz depending on the size and
purpose of the cleaning object, and is generally 20 to 50 kHz. As
the frequency of the ultrasonic transducer increases, a Langevin
oscillator, a longitudinal vibrator, a thickness vibrator, and the
like can be used. In terms of miniaturization, there are also
radial vibrations and bending vibrations using a disk oscillator.
Ultrasonic cleaning is used more and more widely in various
industries, agriculture, household equipment, electronics,
automotive, rubber, printing, aircraft, food, hospital and medical
research.
2, ultrasonic welding
Ultrasonic welding has two major categories: ultrasonic metal
welding and ultrasonic plastic welding. Among them, ultrasonic
plastic welding technology has been widely used. It uses ultrasonic
vibration generated by the transducer to transmit ultrasonic
vibration energy to the weld zone through the upper weldment. Since
the welding zone, that is, the sound resistance at the junction of
the two weldments is large, local high temperature is generated to
melt the plastic, and the welding work is completed under the
contact pressure. Ultrasonic plastic welding facilitates the
welding of parts that cannot be welded by other welding methods. In
addition, it also saves expensive mold costs for plastic products,
shortens processing time, improves production efficiency, and is
economical, fast, and reliable.
