Working Principle of Ultrasonic Cleaning Machines

Ultrasonic cleaning is based on the physical effect of "cavitation" when ultrasonic waves propagate through the cleaning liquid medium. The ultrasonic generator produces electrical energy with a frequency higher than 20 kHz, which is converted into ultrasonic energy by the transducer and transmitted into the cleaning medium. When the intensity of the ultrasonic field exceeds the cavitation threshold of the cleaning medium, numerous expanding "cavities" rapidly form in the cleaning liquid due to ultrasonic negative pressure. During ultrasonic positive pressure, these "cavities" are strongly compressed, creating microscopic intense shock waves and high-speed jets that act on the surface of the object being cleaned, rapidly crushing and dislodging contaminants.

Materials Used in Commercial Ultrasonic Cleaning Machines

Standard configuration includes an integrally stamped stainless steel tank, ranging from 0.8L to 30L, with a stainless steel body material.

Main Parameters
1. Frequency: ≥20 kHz, which can be divided into low, medium, and high frequency ranges.
2. Cleaning Medium: Chemical solvents or water-based cleaning agents, combining chemical action with the physical effects of ultrasonic cleaning for better results.
3. Power Density: Power Density = Transmitted Power (W) / Transmitted Area (cm2), typically ≥0.3 W/cm2. The higher the power density of the ultrasound, the stronger the cavitation effect, the faster the speed, and the better the cleaning performance.

Ultrasonic Frequency for Cleaning Objects

Powder metallurgy parts such as magnetic cores, magnetic rings, and items with grinding magnetic powder: choose a frequency of 20-25 kHz;
Rough metal components, such as automotive wheel hubs, cylinder assemblies, and other large parts: choose a frequency of 25-28 kHz;
For watch components and precision stamped parts: choose a frequency of 40 kHz;
For optical glass and low-end LCD devices: choose a frequency of 68-120 kHz;
For cleaning semiconductor wafers and LCD glass substrates to remove 1-3 μm contaminant particles: choose a megahertz-level frequency of 0.8-1.0 MHz.
