6.5L Polishing Wax Cleaning Equipment Ultrasonic Cleaner

Working Principle of Ultrasonic Cleaners

Ultrasonic cleaning is based on the physical effect of "cavitation" when ultrasonic waves propagate through a liquid cleaning 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 ultrasonic field intensity 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, generating microscopic intense shock waves and high-speed jets that act on the surface of the object being cleaned, causing contaminants to be quickly crushed and dislodged.

Ultrasonic cleaners are efficient and environmentally friendly cleaning devices that utilize the cavitation effect produced by ultrasound in liquids to clean the surfaces of metal and plastic parts. They mainly consist of an ultrasonic generator, a transducer, and a cleaning tank, capable of cleaning every crevice and corner of complex workpieces to achieve high-efficiency cleaning results. They are widely used in various industries such as surface coating treatment, machinery, electronics, semiconductors, watchmaking and jewelry, optics, textile printing and dyeing, and more. For example, in the machinery industry, they can be used to remove contaminants like cutting oil, abrasive particles, iron chips, and dust; in the electronics industry, they can clean dust and oil stains from the surfaces of electronic components.

Recommended Applications for Yunyi Commercial Ultrasonic Cleaner Series
YB Series: Suitable for cleaning PCB boards, 3D printed models, and items requiring volatile cleaning agents;
YD Series: Equipped with heating function, ideal for cleaning heavy oil, severe rust, and stubborn stains;
YS Series: Features degassing function, suitable for cleaning oxidation-prone objects;

YW Series: Equipped with degassing and variable frequency functions, recommended for laboratory use or cleaning highly precise objects;

Main Features
1. High-Efficiency Cleaning: Ultrasonic cleaning equipment can accommodate batch cleaning of multiple workpieces and clean every crevice and corner of complex workpieces, achieving high-efficiency cleaning results.
2. Reduced Labor Intensity: Ultrasonic cleaning offers fast and efficient cleaning effects, reducing workers' labor intensity and creating a clean and orderly cleaning environment.
3. Environmentally Friendly Cleaning: Ultrasonic cleaners are equipped with an efficient circulating filtration system. Used cleaning solvents can be filtered through the system for repeated use, thereby conserving water resources and cleaning solvents, reducing cleaning costs for enterprises, and enhancing environmental sustainability.
Ultrasonic frequency: For conventional cleaning, frequencies are typically selected in the ranges of 20-40 kHz and 68-120 kHz. The lower frequency range is suitable for removing contaminant particles sized 3-5 μm.

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 to achieve better cleaning results.
3. Power Density: Power density = transmitted power (W) / transmitted area (cm²), typically ≥0.3 W/cm². The higher the power density of ultrasound, the stronger the cavitation effect, the faster the cleaning speed, and the better the cleaning results.
