OURS supply Ultrasonic Converter 40KHZ PZT8 Or PZT4 High Performance For Korean Household Washing Machine

Ultrasonic transducers are piezoelectric ceramics that resonate at ultrasonic frequencies. The piezoelectric effect of the material converts electrical signals into mechanical vibrations. The working principle of medical ultrasonic transducers (ultrasound probes) is basically the same, and its interior usually contains an electrical energy storage element and a mechanical vibration system. When the transducer is used as a transmitter, the electric oscillation signal sent from the excitation power supply will cause the electric field or magnetic field in the electric energy storage element of the transducer to change. This change affects the mechanical vibration system of the transducer through a certain effect. A driving force is generated to enter the vibration state, thereby driving the medium in contact with the mechanical vibration system of the transducer to vibrate and radiate sound waves into the medium. The process of receiving sound waves is just the opposite. The external sound waves act on the vibrating surface of the transducer, which causes the mechanical vibration system of the transducer to vibrate. With the help of a certain physical effect, it causes the electric field or electric field in the energy storage element of the transducer. The magnetic field changes accordingly, causing the electrical output of the transducer to generate a voltage and current corresponding to the acoustic signal.
Introduction to Ultrasonic Transducers
Ultrasonic vibrator, also called ultrasonic vibrator, ultrasonic vibrator, is a kind of ultrasonic transducer and the core component of ultrasonic cleaning machine. We call the whole of ultrasonic transducer and horn connected as vibrator. Ultrasonic transducer is one of the important components in the ultrasonic cleaning machine and ultrasonic vibration plate, which largely determines the quality of the ultrasonic effect.
Our company provides professional ultrasonic transducers with stable quality, high efficiency output and moderate price based on many years of ultrasonic cleaning experience, combined with the opinions and feedback of users.
Ultrasonic transducer is a device that converts high-frequency electric energy into mechanical vibration. The high-frequency electric energy input by the ultrasonic generator is matched with the piezoelectric ceramic sheet of the resonance frequency of the ultrasonic transducer. The electric energy is converted by the piezoelectric effect of the material. Converted into mechanical vibration, that is, ultrasonic vibration, is transmitted to the water medium through the ultrasonic transducer, forming negative pressure bubbles and shock waves in the water, and transmitted in the tax-based solution to achieve the effect of cleaning the surface of the workpiece. The transducer is mainly composed of aluminum block, piezoelectric ceramic sheet and insulating layer.
28KHZ/40KHZ/25KHZ/68KHZ/80KHZ/120KHZ/200KHZ and other ultrasonic vibrators (ultrasonic transducers) are widely used in the electronics industry, machinery industry, automotive, electroplating, chemical fiber,
Optical, bearing and other industries. Such as cleaning magnetic cores, oil nozzles, auto parts, electroplating hardware tools, chemical fiber spinnerets, optical lenses, bearings, tools, tableware, medical equipment, precision hardware, watch parts, gold and silver jewelry, electronic components. This frequency has strong vibration and uniform density, which can quickly achieve the purpose of degreasing, sodium removal, decontamination and descaling. In addition, it can also be used in chemical experiments to achieve catalysis, stirring, and rapid generator chemical reactions.

The mechanism of ultrasonic cleaning is to make use of the physical effects such as cavitation, radiation pressure and sound flow in the cleaning liquid. It can exfoliate the machinery produced by the dirt on the cleaning parts, and can also promote the chemical reaction between the cleaning liquid and the dirt, so as to achieve the purpose of cleaning the object. The frequency of the ultrasonic cleaning machine can be selected by 10~500 kHz according to the size and purpose of the cleaning material, generally more than 20~50 kHz. With the increase of the frequency of ultrasonic transducer, Langerhans oscillator, longitudinal oscillator and thickness oscillator can be used. In the miniaturization aspect, radial vibration and flexural vibration are also adopted. Ultrasonic cleaning has become more and more widely used in various industries, agriculture, household equipment, electronics, automobile, rubber, printing, aircraft, food, hospital and medical research.

Install an ultrasonic oscillator, you must first understand the structure of the ultrasonic oscillator and the working principle of the ultrasonic oscillator. In fact, the ultrasonic oscillator is also called an ultrasonic oscillator.
The ultrasonic vibrator is a device that realizes the mutual conversion of electrical energy and mechanical energy (acoustic vibration) by the piezoelectric effect of piezoelectric ceramics, and amplifies the acoustic impedance matching front and rear radiation cover blocks. The ultrasonic vibrator is composed of an ultrasonic transducer and an ultrasonic horn. The ultrasonic transducer is a device that can convert high-frequency electrical energy into mechanical energy. The ultrasonic horn is a passive device that does not generate vibration itself. It only transmits the amplitude of the vibration input by the ultrasonic transducer before changing it. Impedance transformation.

Principle of ultrasonic vibrator arrangement:
(1) Cleaning different product layouts have different requirements, such as the degree of oil staining of the product, the difficulty of cleaning, the level of cleaning requirements, and the design of the cleaning process, all require targeted selection.
(2) The arrangement of the vibrators is not as dense as possible, and the right one is the best.
3. Introduction to ultrasonic vibrator:
The ultrasonic vibrator, also called the ultrasonic vibrating head, is an ultrasonic transducer and is a core component of the ultrasonic cleaning machine. Industry standard name: Ultrasonic transducer, which belongs to piezoelectric ceramic material and one of the main accessories of ultrasonic cleaning machine. From the power point, a single ultrasonic head is 60W, 100W. The frequencies are: 20KHZ, 25KHZ, 28KHZ, 40KHZ, 68KHZ, 80KHZ, 100KHZ, or higher; the difference in shape is: straight cylindrical shape, horn shape, and the like.

Ultrasonic oscillator principle:
1. The piezoelectric element and the internal electrode are alternately stacked in the ultrasonic vibrator, and have an external electrode that is electrically connected to the internal electrode;
The ultrasonic transducer includes an internal electrode group that is substantially divided into four portions along a second direction and a third direction orthogonal to a lamination direction as the first direction, and a first external electrode group and a second external electrode group respectively The electrode group is turned on; by applying an alternating voltage to the first external electrode group and the second external electrode group, the longitudinal vibration mode in which the main vibration occurs in the second direction and the main vibration are in the third direction a bending vibration mode that occurs, thereby generating ultrasonic elliptical vibration;
The ultrasonic transducer includes a conductor film for electrode connection formed along a surface perpendicular to the stacking direction, and predetermined predetermined external electrodes of the first external electrode group and the second external electrode group The external electrodes are electrically connected. A device that converts electrical energy and acoustic energy by piezoelectric effect is called a piezoelectric transducer. The ultrasonic transducer provided by the company uses self-produced high-quality piezoelectric ceramic components, which are carefully designed, processed and tested to be bolts. The fastening type produces stable ultrasonic waves even when the load changes. It has the characteristics of large amplitude, high electroacoustic conversion rate, low heat generation, high reliability and good consistency.
