The core technology of ultrasonic cleaners is the "cavitation effect," which utilizes ultrasonic waves to generate tiny bubbles in a liquid, which then burst instantly, releasing high-temperature, high-pressure shock waves and micro-jets to remove dirt from surfaces and crevices.
This technology is characterized by high efficiency, non-contact operation, and strong penetration, allowing it to clean complex structures (such as deep holes and narrow crevices) without causing physical damage to precision components. Key parameters include:
Frequency: Typically between 20kHz and 1MHz. Low frequencies (20–40kHz) have high cavitation intensity and are suitable for rough cleaning; high frequencies (above 80kHz) have strong directionality and are suitable for precision cleaning.
Power density: Affects the cavitation effect; higher power results in faster cleaning, but excessive power may damage sensitive surfaces.
Cleaning temperature: Generally controlled at 40–50℃ to optimize cavitation efficiency; some devices support constant temperature heating.
Cleaning medium: Used in conjunction with water-based or chemical cleaning agents to achieve synergistic physical and chemical decontamination.
The core technical components include:
Ultrasonic generator: Converts electrical energy into high-frequency electrical signals.
Transducer: Converts the electrical signals into mechanical vibrations via piezoelectric ceramics, transmitting them to the cleaning fluid.
Cleaning tank: Made of corrosion-resistant stainless steel, it holds the cleaning fluid and the items to be cleaned.
