I. Power Selection. ultrasonic cleaner the effect is not necessarily proportional to (power × cleaning time). Sometimes, even with low power and a long time, the dirt cannot be removed. And if the power reaches a certain value, sometimes the dirt can be removed very quickly. If the selected power is too high, the cavitation intensity will increase significantly. Although the cleaning effect is improved, it will also cause corrosion points on more precise parts, which is not worth it. Moreover, the cavitation at the bottom of the cleaning tank and the vibration plate is severe, and the water point corrosion also increases. When using organic solvents such as trichloroethylene, there is basically no problem, but when using water or water-soluble cleaning solutions, it is prone to water point corrosion. If the surface of the vibration plate has been damaged, the cavitation corrosion at the bottom of the water will be more severe under high power. Therefore, the ultrasonic power should be selected according to the actual usage situation.
