13-Station Fully Automatic Ultrasonic Cleaner

　　The principle of a fully automatic ultrasonic cleaner relies on transducers that convert high-power ultrasonic energy from the source into mechanical vibrations. These vibrations are then transmitted through the walls of the cleaning tank, causing the cleaning fluid inside to oscillate under ultrasonic waves. As the ultrasonic waves propagate through the liquid, they create tiny microbubbles within the solution. Under the influence of the sound waves, these bubbles remain in a state of continuous vibration. When the acoustic pressure or intensity reaches a critical threshold, the bubbles rapidly expand and then collapse abruptly. During this collapse, a powerful shock wave is generated, producing localized pressures as high as 10¹² to 10¹³ pascals along with extreme temperature gradients. This intense cavitation effect not only breaks down insoluble contaminants by shattering them into smaller particles dispersed throughout the solution but also delivers a direct, repetitive impact to dirt and grime. On one hand, it disrupts the adhesion between contaminants and the surface of the object being cleaned; on the other hand, it induces fatigue cracking in the contaminant layer, ultimately causing it to detach completely. Meanwhile, gas-filled bubbles vibrate vigorously against solid surfaces, effectively "scrubbing" away dirt and debris. If there’s even a tiny crack or crevice in the contaminant layer, the bubbles can penetrate directly, leveraging their vibrational energy to dislodge and remove the buildup entirely. Additionally, the cavitation process promotes rapid emulsification and dispersion of both liquids at the interface, ensuring thorough mixing and preventing re-deposition of contaminants. When solid particles are coated with oil or grease and adhere to the surface of the object, the cavitation action helps break up the oil film, allowing the particles to shed naturally. As ultrasonic waves travel through the cleaning fluid, they generate alternating positive and negative pressure fluctuations, creating powerful jets that forcefully impact the surface of the object being cleaned. Simultaneously, nonlinear effects give rise to acoustic streaming and microstreaming phenomena, while ultrasonic cavitation near solid-liquid interfaces produces high-speed microjets capable of dislodging even stubborn residues. In essence, these combined mechanisms work together to disintegrate contaminants, eliminate or weaken boundary layers, enhance agitation and diffusion, and accelerate the dissolution of soluble dirt. As a result, ultrasonic cleaning proves highly effective in thoroughly cleaning parts with exceptionally complex geometries—areas where traditional methods might fall short. Notably, adopting this technology significantly reduces the need for harsh chemical solvents, thereby minimizing environmental pollution and promoting more sustainable cleaning practices.
