Ultrasonic Cleaner

　Ultrasonic cleaning machine power selection.

　　When choosing an ultrasonic cleaning machine, the focus is usually on the output power. Generally speaking, the actual effect of ultrasonic cleaning is not necessarily proportional to the output power multiplied by the cleaning time.

　　If the choice of ultrasonic cleaning machine output power is relatively small, even for a long time will not completely eliminate the stain; if the output power is relatively large, although you can quickly remove the stain in the shortest possible time, but also on the object being cleaned will cause some loss. Therefore, in the choice of ultrasonic cleaning machine, you must choose the appropriate output power.

　　When the output power is too high, the bottom of the cleaning cylinder vibration plate cavitation serious, the water point corrosion will also increase. If you choose trichloroethylene and other solvents, there may be no problem, but if you choose water or water-soluble cleaning solution, it will suffer from water pitting corrosion.

　　In short, in the choice of ultrasonic cleaning machine, you must choose and match the output power to ensure the cleaning effect.

　　Ultrasonic cleaning machine has always been a remarkable cleaning effect, easy to operate, popular with everyone. But you may have just heard of this equipment, how it works, how it works, it makes no sense. So here's how to choose the power and frequency of this ultrasonic cleaner, let's take a look.

　　1 when the power is too high.

　　Ultrasonic cleaning machine power, the sound intensity increases, the cavitation bubble radius and initial radius increases, the cavitation intensity increases. That is, the higher the sound intensity, the stronger the cavitation, which is conducive to cleaning. But the higher the power the better the cleaning effect, but the correct and reasonable choice of ultrasonic power.

　　2 small power deviation.

　　The higher the sound power, the more obvious the cavitation effect, producing a large number of useless bubbles, increasing diffraction attenuation and forming a sound barrier. At the same time, the higher the sound power, the greater the nonlinear attenuation, which will affect the cleaning effect of the cleaned parts away from the sound source. In addition, the cleaning vibration plate cavitation more serious, resulting in shortened equipment life. If the ultrasonic cleaning power is too small, it will affect the cleaning time of the workpiece, cleaning time will be longer, or the cleaning effect will be deviated.

　　3 power supply selection.

　　So we choose ultrasonic cleaning equipment, the height of the workpiece is generally below 30cm, so ultrasonic cleaning equipment in the tank is about 40cm high, the bottom of the choice of a single vibration plate, the power is kept at 0.3 to 0.5w per square centimeter. if the workpiece is too large, or each cleaning volume is too large, we choose the height of the tank in more than 40cm, generally in accordance with the power increase to calculate, generally choose 11W / L.

　　1 high-frequency and low-frequency impact.

　　Ultrasonic cavitation threshold is closely related to the frequency. The higher the frequency, the higher the cavitation threshold. The lower the frequency, the lower the cavitation threshold, the greater the possibility of cavitation. At low frequencies, the liquid is compressed and thinned over long intervals. Make bubbles grow to a larger size, enhance the strength of cavitation and facilitate cleaning. Therefore, low-frequency ultrasonic cleaning is generally used for large parts surface or dirt on the surface of the workpiece when the adhesion is high. But easy to damage and corrosion of the workpiece surface. Therefore, the workpiece surface requirements of higher parts should not be selected for lower frequency. The frequency is lower, the noise generated is correspondingly larger. Select the frequency according to different situations.

　　High-frequency ultrasound penetration, suitable for high surface finish requirements or complex surface, blind hole more parts cleaning. On the other hand, high-frequency ultrasonic noise is also small, suitable for cleaning some precision parts, such as some electronic parts, small bearing processing, magnetic materials, etc.. For some special workpieces, such as integrated circuit chips, higher frequency ultrasonic cleaning is suitable for silicon wafer plating. For some large workpieces, such as automobile engines, valves and other large workpieces, should be selected for low-frequency ultrasonic cleaning. On the other hand, taking into account the effectiveness and economy of ultrasonic cleaning, the frequency is generally selected between 20 kHz and 130 kHz. The specific choice of frequency to be determined by the corresponding experiments.

　　These are some choices of ultrasonic cleaning machine power and frequency, I hope it will help you. Ultrasonic cleaning machine is used in many fields, the effect is very significant. In order to maintain this effect, we should carry out daily maintenance of the machine, timely repair of faults, to ensure the working performance of the cleaning machine.
