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.

High-frequency ultrasonic cleaning is suitable for the fine cleaning of computers and microelectronic components; megahertz ultrasonic cleaning is suitable for the cleaning of integrated circuit chips, silicon wafers and wave films. It can remove micron and sub-micron dirt without any damage to the cleaning parts. Therefore, considering the cleaning effect and economy, the frequency is generally selected in the range of 20-130KHZ. Of course, the correct selection of the frequency is very important, and the selection of the specific suitable working frequency requires certain experiments to obtain

High frequency is usually used to clean smaller, more precise parts, or to remove tiny particles. High frequency is also used in applications where the surface of the workpiece is not allowed to be damaged. Using high frequency can improve cleaning performance in several ways. As the frequency increases, the number of cavitation bubbles increases linearly, which generates more and denser shock waves that can enter smaller gaps. If the power remains the same, the cavitation bubble becomes smaller, and the energy released by it is reduced accordingly, which effectively reduces the damage to the surface of the workpiece. Another advantage of high frequency is that it reduces the viscous boundary layer (Ponury effect), so that ultrasound can'discover' extremely fine particles. And our Boda high frequency ultrasonic vibrator also has 68KHZ, 80KHZ, 100KHZ, 120KHZ.

To install an ultrasonic vibrator, you must first understand the structure of the ultrasonic vibrator and the working principle of the ultrasonic vibrator. In fact, the ultrasonic vibrator is also called the ultrasonic vibrator. In the industry, the whole of the transducer and the horn is called the vibrator.
Ultrasonic vibrator is a device that realizes the mutual conversion between electrical energy and mechanical energy (acoustic vibration) by the piezoelectric effect of piezoelectric ceramics, and amplifies the device through the front and rear radiation cover blocks that match the acoustic impedance. The ultrasonic vibrator is composed of an ultrasonic transducer and an ultrasonic horn. Ultrasonic transducer is a device that can convert high-frequency electrical energy into mechanical energy. Ultrasonic horn is a passive device that does not produce vibration itself, but only changes the vibration input from the ultrasonic transducer before transmitting it out. The impedance transformation.
Install the ultrasonic vibrator steps and preparation tools:
1. Preparation tools: Argon arc welding, No. 10 hexagon wrench, chromium iron tin wire, 2.5 square high temperature wire, 2*2.5 cable wire, vibrator glue, (wire stripper, casing, cable tie, sandblasting machine, Pipe fittings, etc.).
2. Welding screws: Calculate the placement of the vibrator, weld the screws at the cleaned position, and then clean the surrounding of the screw. Make sure to make it level so as not to affect the installation of the vibrator.
3. Glue configuration: Stir the glue evenly according to the specified ratio. (Merry, Araldite, 4030 glue is mixed before bonding, and KMD398 glue is mixed during the bonding process).
4. Install the vibrator: smear the glue evenly on the bottom of the ultrasonic vibrator, gently twist to squeeze out the air and excess glue between the bottom of the transducer and the contact surface of the cylinder bottom, so that the vibrator is more closely integrated with the stainless steel. .
5. Curing and condensing: curing in a relatively high room temperature place, 4-8 hours can be connected, after 24 hours, you can power on the test machine, the test machine is absolutely not allowed to empty vibration.
Note: 1. A metal nail machine can also replace argon arc welding. 2. The welding screws must be fully welded, otherwise they will fall off easily. 3. Regarding curing, temperature should be considered for the length of time. If the temperature is low, the time will be longer, and if the temperature is high, it will be faster. It is recommended to operate at room temperature.
