The field of high power ultrasonic transducer application is inconsistent in different installation methods, which leads to special requirements on the shape of the transducer. The company specializes in the production of ultrasonic transducers, and designs the corresponding parameters for the different requirements of customers. A device that converts electrical energy into mechanical energy (ultrasonic waves), the most mature and reliable piezoelectric ultrasonic transducer that converts electrical energy and acoustic energy by piezoelectric effect, called a 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. This sandwich transducer (bolt-type 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, they are mainly in the form of columns (the front and rear metal cover plates have the same diameter), the inverted horn type (the front cover diameter is excessively reduced by the arc shape), the cylindrical steel back cover, and the middle of the column type.
main feature:
Large amplitude: The structure optimized by computer, the vibration speed ratio is high, and the amplitude of the front cover is large.High power: Under the action of the pre-stressed screw, the energy of the piezoelectric ceramic is maximized.Good heat resistance: low resonance impedance, low heat generation, and wide temperature range in the high reliability and long life.
