Description:
The transducer converts high-frequency electrical energy into high-frequency mechanical vibrations. And it contains several piezoelectric ceramic discs sandwiched under pressure between two metal blocks. Between each disc is a thin metal plate, which forms the electrode. When a sinusoidal electrical signal is fed to the transducer via the electrodes, the discs expand and contract, producing axial vibrations.
15Khz transducer widely used in high power welding&sealing system.Piezoelectric transducer is the electric charge that accumulates in certain solid materials in response to applied mechanical stress. It is key point of all ultrasonic equipment.The transducer decide the property of the machine.We can supply transducer, also transducer with house and booster.
Ultrasonic transducers transform electrical output from the power supply into vibrational output. This electormechanical transformation may be accomplished by piezoelectric ceramics (below) or magnetostrictive materials (discussed elsewhere).
Transducer requirements will depend on the application. Many requirements will conflict with one another and will be given different priorities. Hence, no single set of guidelines can encompass all requirements — i.e., there are many different ways to achieve the same objectives.
Analytically, transducer performance can only be predicted in a general way. This is because the properties of piezoelectric ceramics are often highly dependent on the operating conditions including temperature, electrical field strength, static compressive prestress, dynamic stress, number of load cycles, and time. These operating conditions can interact with each other and the effects of these conditions are often nonlinear. Also, many properties of piezoelectric ceramics are orthotropic and can vary among the individual ceramics and also between ceramic lots. Further, the interactions at the various component interfaces (e.g., at threads) may be difficult to characterize and the coefficient of convective heat transfer for air cooling may only be approximately estimated. Hence, much of the design process involves experimental testing.
Advantage
High efficiency: high mechanical quality factors and high efficiency of electroacoustic conversion at resonant frequency points.
Large amplitude: the structure of the computer optimized design, the ratio of vibration and speed is high, and the amplitude of the front cover plate is large.
Big power: under the action of the pre-stressed screw, the energy of the piezoelectric ceramic is exerted to the maximum extent.
Good heat resistance: small resonant impedance, small calorific value, wide range of use temperature. High reliability and long life.
