How to choose the power when purchasing an ultrasonic cleaner
The choice of ultrasonic cleaning machine power will have a great impact on the cleaning effect and cleaning time of the ultrasonic cleaning machine. Only a reasonable selection of the ultrasonic cleaning machine power will produce a good cleaning effect. When we are purchasing an ultrasonic cleaning machine, we must not only look at its capacity, frequency, but also the power of the ultrasonic cleaning machine. Often, everyone just doesn't know how to choose and can't choose the ultrasonic cleaning machine that suits them. Ultrasonic instrument Xiaobian tell everyone.
1. The higher the power, the better the cleaning effect, but the correct and reasonable choice of ultrasonic power ultrasonic cleaning machine ultrasonic cleaning effect is not necessarily proportional to (power × cleaning time), sometimes with low power, it takes a long time Remove dirt. And if the power reaches a certain value, the dirt is sometimes removed quickly. If the power is too large, the cavitation intensity will be greatly increased, and the cleaning effect will be improved. However, the more precise parts will also have an etch point, which is not worth the loss. Moreover, the cavitation at the bottom of the cleaning tank of the ultrasonic cleaning machine is severe, and the water point corrosion is also increased. When using an organic solvent such as trichloroethylene, there is basically no problem, but when using water or a water-soluble cleaning solution, it is easy to receive water. Corrosion, if the surface of the vibrating plate has been scratched, cavitation corrosion is more serious under the high power, so the ultrasonic power should be selected according to the actual use.
2. The choice of ultrasonic cleaning machine power, ultrasonic cavitation threshold and ultrasonic frequency are closely related to the choice of ultrasonic cleaning machine power, ultrasonic cavitation threshold and ultrasonic frequency are closely related, the higher the frequency, the higher the cavitation valve . In other words, the frequency is low, the cavitation is more likely to occur, and the compression and sparse action of the liquid at lower frequencies has a longer time interval, allowing the bubble to grow to a larger size and increase the cavitation intensity before collapse. Conducive to cleaning. The frequency around 40KHZ, under the same sound intensity, the number of cavitation bubbles generated is more than the frequency of 20KHZ, and the penetrating power is strong. It is better to clean the workpiece with complex surface shape or blind holes, and the cavitation noise is small, but empty. The strength is low, and it is suitable for the occasion where the cleaning dirt and the surface of the surface to be cleaned are weak.
3, ultrasonic cleaning machine power calculation formula (1), according to the transducer (commonly known as the vibration head) to calculate, the current market power converter has two kinds of power: 50W / 1PCS; 60w / PCS. The power of an ultrasonic cleaner: the number of transducers is N*50W or N*60W. (2), know the length and width of the cleaning tank can be, 100mm distance from a vibrator, both horizontal and vertical are the distance, the vibration power is generally 50W or 60W. 600 * 400 = 240000 divided by 10000 = 24 vibrators 24 *50=1200W 24*60=1440W (3), the tank body is generally placed at the bottom, 600*400mm surface. Generally, 24 vibrators can be arranged evenly. If the pollution is heavy, the power can be increased appropriately. Place 28, the total power is about 1400w, and it is suitable to use a 1500w generator. (4) If the vibrator is placed below, the power calculation of the ultrasonic cleaner is 60*40*0.55=1320W.
The ultrasonic cavitation threshold is closely related to the frequency. The higher the frequency, the higher the cavitation threshold. The frequency is low, and the lower the cavitation threshold, the easier it is to cavitation. Low-frequency ultrasonic cleaning is generally used on the surface of large parts or where the adhesion of dirt to the surface of the workpiece is high. High-frequency ultrasonic waves are suitable for cleaning some precision parts. Considering the ultrasonic cleaning effect and economy, the frequency is generally selected from 20 to 130 kHz.
