Working Principle Of Industrial Ultrasonic Cleaning Machines

An ultrasonic cleaning machine mainly consists of a generator, a transducer, and a cleaning tank. The generator converts electrical energy into a high-frequency electrical signal (typically 20-40kHz). The transducer (using piezoelectric ceramic or magnetostrictive material) then converts the electrical signal into mechanical vibration, which is transmitted to the liquid in the cleaning tank. Under the action of ultrasound, the liquid forms countless tiny bubbles (cavitation bubbles). These bubbles rapidly grow and violently collapse under changes in sound pressure, generating localized high pressure (up to 1000 atm) and high temperature (approximately 5000K), thereby removing dirt.
