Product Description

The ultrasonic sensor produced by the company is a piezoelectric ceramic conversion device, which converts a high-frequency sinusoidal voltage signal into a high-frequency mechanical vibration signal, which is installed on the bottom or side wall of the cleaning tank, and is transmitted through the tank and acts on the cleaning medium. The vibration signal of the vibrator is converted into a cavitation effect, and the attachment of the object is quickly peeled off to achieve the purpose of cleaning.

The ultrasonic vibrators produced by the company are characterized by low heat generation, good thermal stability, low resonance impedance, good consistency between frequency and static capacitance, and complete and smooth waveforms of frequency and impedance.
Ultrasonic vibrators have multiple resonance points. Using the second and third resonance points of the vibrator, we have developed dual-frequency ultrasonic vibrators and three-frequency ultrasonic vibrators, which are effective in ultrasonic cleaning machines. The company can customize them according to your needs. Various types of ultrasonic vibrators can achieve a higher level of cleaning effect.

Principle of ultrasonic vibrator:
1. In the ultrasonic vibrator, piezoelectric elements and internal electrodes are alternately stacked, and have external electrodes that are connected to the internal electrodes;
This ultrasonic vibrator has: an internal electrode group, which is roughly divided into 4 parts along the second and third directions orthogonal to the lamination direction as the first direction; the first external electrode group and the second external electrode group are connected to the internal 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 in the third direction are simultaneously excited The bending vibration mode that occurs, resulting in ultrasonic elliptical vibration;
The ultrasonic vibrator is configured to have a conductive film for electrode connection, which is formed along a surface perpendicular to the lamination direction, and separates predetermined external electrodes of the first external electrode group and predetermined external electrodes of the second external electrode group. The external electrodes are electrically connected. The device that uses piezoelectric effect to convert between electrical energy and sound energy is called piezoelectric transducer. The ultrasonic transducer provided by our company uses self-produced high-quality piezoelectric ceramic components, carefully designed, processed, and tested. It is a bolt The tightening type can generate stable ultrasonic waves even when the load changes. It has the characteristics of large amplitude, high electro-acoustic conversion rate, low heat generation, high reliability and good consistency.

In some places, such as when cleaning deep screw holes, it is advisable to use a vibrator with high radiation sound intensity. At this time, the radiator of the vibrator often has a sharpened focus shape to increase the sound intensity of the radiation surface. This kind of vibrator is generally not glued to the cleaning tank, but directly pulled out of the liquid for cleaning.
The distribution and bonding of ultrasonic vibrators in the cleaning tank At present, some ultrasonic cleaning machine products are densely distributed on the bottom or wall of the cleaning tank. The vibrators are arranged next to each other. The input power of the vibrator reaches 2 per square centimeter -3 watts, such a high strength will accelerate the cavitation corrosion of the surface of the stainless steel plate (the surface in contact with the cleaning fluid) and shorten the service life. On the other hand, the sound intensity is too high. A large number of large bubbles will occur near the surface of the steel plate, increasing the sound transmission loss, and weakening the cleaning effect far away from the vibrator.
The bonding quality of the vibrator and the cleaning tank has a great influence on the quality of the ultrasonic cleaning machine. Not only must it be adhered firmly, but also the glue layer must be uniform, no lack of glue and no cracks allowed, so that the ultrasonic energy can be maximized in the cleaning liquid Transmission to improve the efficiency and cleaning effect of the whole machine. At present, some cleaning equipment is to prevent the vibrator from falling off the cleaning tank. The fixing method of screws and glue is adopted. Although the vibrator will not fall off in this connection method, there are many hidden dangers. If the screw welding quality is poor, such as not perpendicular to the surface of the stainless steel plate, the glue layer will be uneven, even cracks or lack of glue, and the energy transmission will be weakened; on the other hand, if the welding is not good, it will also affect the smoothness of the stainless steel surface, resulting in acceleration Cavitation corrosion, shorten the service life. One of the methods to judge the bonding quality is to measure the temperature rise of the vibrator after the cleaning tank is filled with water and turned on for a period of time. If the temperature of one of the many vibrators rises very quickly, it indicates that the vibrator may not be well bonded. Because the sound radiation is not good at this time, most of the electric energy is consumed on the vibrator and generates heat. Another method is to measure the electrical impedance of the vibrator one by one under small signal conditions to judge the bonding quality.

Ultrasonic cleaning transducer application:
Ultrasonic transducers are widely used. They are divided into industry, agriculture, transportation, life, medical and military according to the applied industry. According to the functions realized, it is divided into ultrasonic processing, ultrasonic cleaning, ultrasonic detection, detection, monitoring, telemetry, remote control, etc.; according to the working environment, it is divided into liquid, gas, biological, etc.; according to the nature, it is divided into power ultrasonic, ultrasonic detection, ultrasonic imaging, etc.
