Inverted Flange Ultrasonic Piezoelectric Transducer For Non Woven Sealing

Product Specification

Inverted Flange Ultrasonic Transducer for Non woven Sealing Machine​

Description:

Ultrasonic transducers are devices that convert electrical energy into mechanical energy ultrasonic waves. The most mature and reliable device that converts electrical energy and acoustic energy by piezoelectric effect is called piezoelectric transducer.
It consists of a central piezoceramic component, a front and rear metal cover, a pre-stressed screw, an electrode pad and an insulating tube. The sandwich transducer bolt-on transducer produces stable ultrasonic waves when the load changes, and is the most basic and most important method for obtaining a power ultrasonic drive source. According to different designs, the ultrasonic transducers are mainly in the form of the same shape of the front and rear metal cover plates. The diameter of the inverted horn type front cover plate is excessively reduced by the arc type, the cylindrical steel back cover, and the column type has a section in the middle.

Application fields of piezoelectric ceramics:

Today, the range of piezoelectric ceramic products is not only widely used in medical and industrial fields, but also penetrates into every corner of people's daily life. Its application areas mainly involve the following five aspects:
First, the frequency control device. In recent years, there have been ceramic resonators, ceramic filters, tuning tuning fork filters, mechanical filters, ceramic discriminators, traps and delay lines. Among them, the output of ceramic resonators and ceramic filters has accounted for more than 65% of China's piezoelectric ceramic products, which is quite remarkable. In particular, ceramic resonators are characterized by high stability, no adjustment, small size and low cost. Typical applications are: televisions, camcorders, computers, CD-ROM drives, automotive electronics, VCDs, telephones, copiers, speech synthesizers, remote controls and toys.
Second, piezoelectric ultrasonic transducers. Piezoelectric ultrasonic transducers are acoustic devices that transmit and receive ultrasonic waves and are widely used in water and air media. The role of radar in underwater acoustic communication, known as sonar, is an essential sensor for all types of ships. In the industry, ultrasonic transducers have been used for ultrasonic cleaning, ultrasonic precision machining, ultrasonic humidification, phacoemulsification, ultrasonic seed treatment, ultrasonic flaw detection and ultrasonic diagnosis. Today, another broad application area for piezoelectric ultrasonic transducers is telemetry, remote control systems, and alarm systems.
Third, the piezoelectric sounder. Typical products of piezoelectric sounders are piezoelectric buzzers and piezoelectric transmitters, receivers, watches, calculators, electronic alarm clocks, small alarm bells, and ringing of telephones and mobile phones. Buzzer with transistor oscillating circuit and DC power supply can make continuous sound, buzzer with switching circuit can make intermittent sound, underwater microphone and speaker belonging to sound transducer can also be used to drive or seduce Fish school.
Fourth, piezoelectric devices for measurement and control. Piezoelectric devices for measurement and control mainly include pressure, acceleration, angular velocity sensors, as well as ultrasonic sounding, ultrasonic thickness measurement, ultrasonic flow measurement, and ultrasonic diagnosis.
Fifth, piezoelectric igniters and piezoelectric transformers. Mass production of piezoelectric igniters began in 1965, and has been developed more rapidly in the past 20 years. At present, almost all gas stoves, bathroom gas boilers, gas room heaters, gas water heaters and cigarette lighters use piezoelectric igniters. Piezoelectric transformer has the advantages of simple structure, small size, high transformation ratio, high electromechanical conversion efficiency, no electromagnetic interference and safety, etc., so it is used for electrostatic smoke remover, negative ion generator, electrostatic coating equipment, electrostatic copier, electric field treatment. Instrument and LCD backlight.
