When the sound intensity increases, the ratio of the maximum radius of the cavitation bubble to the initial radius increases, and the cavitation intensity increases, that is, the higher the sound intensity, the more intense the cavitation, which is conducive to ultrasonic cleaning. However, the greater the ultrasonic sound power, the better, the sound intensity is too high, will produce a large number of useless bubbles, increase the scattering attenuation, the formation of the sound barrier, and the increase in sound intensity will also increase the nonlinear attenuation, which will weaken the cleaning effect away from the sound source. Therefore, the effect of ultrasonic cleaning is not proportional to the added power and working time, and sometimes it takes a long time to remove the dirt with a small power, and if the power reaches a certain value, it is possible to remove the dirt quickly.
If the ultrasonic power is too large, the cavitation strength in the liquid is greatly increased, the more sophisticated parts will produce corrosion points, water point corrosion is also increased, if the surface of the vibration plate has been cavitation corrosion, strong power underwater cavitation corrosion is more serious, reducing the life of the equipment, causing unnecessary losses, while cleaning the bottom of the cylinder vibration plate cavitation is also very serious, shorten the life of the cylinder.
However, the ultrasonic cleaning power selection is small, and it takes a long time to remove the dirt, which is also not advisable. Conventional ultrasonic cleaning in the industry, the standard ultrasonic cleaning machine from 100W to 1500W, how large the workpiece, considering the cleaning rhythm of the premise, by the size of the ultrasonic cleaning tank body to determine the ultrasonic power. In view of the current reverberation field sound intensity measurement technology is not mature enough, it is still designed with the power per unit area, generally a standard ultrasonic cleaning machine output power density is mostly selected in 0.3 ~ 0.6 watts/square centimeter or so, of course, this is just a routine situation. Pulse focused ultrasonic cleaning options are higher.

Therefore, the best way is to generally do the experiment first to obtain the appropriate parameter configuration, and configure the ultrasonic power according to the actual use, which is conducive to practical application. In addition, in the purchase of ultrasonic cleaning machine, you can try to choose a cleaning machine with adjustable power.
