Ultrasonic transducer is the conversion of electrical energy into mechanical vibration and amplification of the amplitude of the components, including ultrasonic transducer, ultrasonic amplitude rod and ultrasonic welding head. Ultrasonic plastic welding machine on the working principle of the ultrasonic transducer, is the use of piezoelectric ceramic material inverse piezoelectric effect produces vibration work.
Piezoelectric crystal placed in the external electric field, under the action of the electric field, caused by the crystal inside the positive and negative charge center of gravity of the movement, this polarization displacement and lead to crystal deformation, which is called the inverse piezoelectric effect.
Extended information:
Ultrasonic transducer applications are very wide, it is divided into industry, agriculture, transportation, life, medical and military applications. According to the realization of the function is divided into ultrasonic processing, ultrasonic cleaning, ultrasonic detection, detection, monitoring, telemetry, remote control, etc.; according to the working environment is divided into liquid, gas, living organisms, etc.; according to the nature of the power is divided into ultrasonic, detection of ultrasound, ultrasonic imaging.
The mechanism of ultrasonic cleaning is the use of ultrasonic propagation in the cleaning fluid, cavitation, radiation pressure, acoustic flow and other physical effects, the dirt on the cleaning parts of the mechanical peeling effect, while promoting the cleaning fluid and dirt chemical reaction, to achieve the purpose of cleaning objects. Ultrasonic cleaning machine used in the frequency according to the size and purpose of the cleaning object can be selected 10 ~ 500 kHz, generally more for 20 ~ 50 kHz.
