28KHz 100W Ultrasonic Cleaning Transducer Oscillator For Engine Parts Degreasing Oil Washing Machine

When cleaning deep screw holes The vibrator with high radiation sound intensity should be used. At this time, the radiator of the ultrasonic cleaning transducer often has a sharp focus shape to improve the sound intensity of the radiation surface. This vibrator is generally not stuck on the cleaning tank, but directl…

28KHz 100W Ultrasonic Cleaning Transducer Oscillator For Engine Parts Degreasing Oil Washing Machine

The distribution and adhesion of Ultrasonic Transducer in the cleaning tank At present, some ultrasonic cleaning machines are available. The vibrators glued to the bottom or wall of the cleaning tank are too closely distributed, one by one The electric power intensity of the input vibrator reaches 2-3 watts per square centimeter. On the one hand, this high intensity will accelerate the cavitation corrosion of the stainless steel plate surface (the surface in contact with the cleaning solution), shorten the service life, and on the other hand, because of the high sound intensity. A large number of large bubbles will occur near the surface of the steel plate, increasing the sound transmission loss, and the cleaning effect will be weakened at the place far away from the vibrator.

The bonding quality between the vibrator and the cleaning tank has a great influence on the quality of the whole ultrasonic cleaning machine It is not only required to stick firmly, but also required that the adhesive layer should be uniform, free of glue shortage and cracks, so as to maximize the transmission of ultrasonic energy to the cleaning solution, so as to improve the overall efficiency and cleaning effect. At present, some cleaning equipment is designed to prevent the vibrator from falling off the cleaning tank. The fixing method of screw and glue is adopted. Although the vibrator will not fall down, there are many hidden dangers. If the welding quality of the screw is poor, such as not perpendicular to the surface of the stainless steel plate, the glue layer is uneven, even cracks or lack of glue, and the energy transmission will be weakened; on the other hand. Poor welding will also affect the flatness of the stainless steel surface, leading to accelerated cavitation corrosion and shortened 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 the machine is started for a period of time. If the temperature rise of a vibrator among many vibrators is especially fast, it indicates that the vibrator may not be well bonded Because the sound radiation is not good at this time, most of the electrical energy is consumed on the vibrator to generate heat. Another method is to measure the electrical impedance of the vibrator one by one under the condition of small signal to judge the bonding quality.
