Rust And Wax Removal Ultrasonic Cleaning Machine

Ultrasonic cleaning machine power selection

Ultrasonic cleaning effect is not necessarily proportional to (power × cleaning time), sometimes with small power, it takes a long time to remove dirt. If the power reaches a certain value, the dirt is sometimes removed quickly. If choose power is too large, the cavitation intensity will greatly increase, cleaning effect is improved, but then make more precision parts also produces erosion point, do more harm than good, and clean the bottom of the cylinder vibrating plate in cavitation is serious, water point corrosion also increases, in using the organic solvent such as trichloroethylene, basically there is no problem, but using water or water-soluble cleaning fluid, vulnerable to water corrosion, If the surface of the vibration plate has been scarred, the underwater cavitation corrosion under strong power is more serious, so the ultrasonic power should be selected according to the actual use situation.

Frequency selection of ultrasonic cleaning machine

In the case of low frequency, the time of compression and tension becomes longer; Therefore, the time and volume of cavitation are also long, and the impact force generated when cavitation is closed is proportional to the size of cavitation bubble. So the lower the frequency, the stronger the cavitation.

While the frequency we use for industrial cleaning is generally less than 60KHz, the most used is between 20 ~ 40KHz. With a frequency of about 20KHz, a relatively small number of cavitation bubbles can be obtained, but with large cavitation strength and accompanied by noise, which can be used to clean the workpiece with high bonding strength between the surface of large parts and the surface of objects.

The frequency of about 40KHz, under the same sound pressure, produces a large number of cavitation bubbles, but the cavitation intensity generated during crushing is low, low noise, strong penetration ability, suitable for complex surface, blind hole, dirt and weak surface bonding force of the workpiece.
