High-Efficiency Chemical Cleaning Line for Industrial and Medical Ultrasonic Cleaning Equipment
Equipment Description
Working Principle
Cavitation Effect
The ultrasonic generator converts electrical energy into a high-frequency electrical signal (20-40kHz). The transducer transmits this high-frequency vibration to the cleaning fluid, creating alternating, dense and sparse acoustic pressure fluctuations. Microscopic bubbles form in the liquid, which repeatedly expand and close under the action of the sound waves, instantly generating thousands of atmospheres of pressure and high temperatures (reaching over a thousand degrees Celsius in some areas), stripping away dirt from the workpiece surface.
Auxiliary Mechanism
Straight Flow Effect: Ultrasonic waves propel the liquid into a unidirectional flow, impacting contaminants trapped in crevices on complex surfaces.
Acceleration Effect: High-frequency vibrations accelerate dirt particles away from the workpiece surface, improving cleaning efficiency.

Application Scenarios
- Industrial: Cleaning oil stains from precision parts, removing mold particles
- Medical: Sterilizing surgical instruments, removing organic matter from laboratory vessels
- Semiconductor and Optics: Damage-free cleaning of wafer surfaces, pre-treatment of lens coatings
Operating Precautions
- Cleaning Fluid Selection: Match the workpiece material (e.g., alkaline fluid for metal parts, neutral fluid for precision parts)
- Parameter Setting: Extend the cleaning time for complex workpieces, and reduce the power for brittle materials to avoid cavitation damage
- Maintenance Requirements: Regularly clean the bottom of the tank, replace the filter bag, and check the transducer's tightness
Main Structures and Components
Core Structure
Ultrasonic Generator
Converts electrical energy into a high-frequency electrical signal (typical frequency 20-40kHz). The power and frequency are adjusted to optimize cleaning results. Some devices support programmable parameter settings (such as cleaning time and power). Built-in components such as a power transformer, oscillator, and power amplifier ensure stable high-frequency signal output.
Transducer
Material and Type: Primarily piezoelectric ceramic (such as lead zirconate titanate PZT). Some use composite transducers or sandwich structures to improve energy conversion efficiency.
Mounting Method: Fixed to the bottom or side of the cleaning tank, the device transmits mechanical vibration energy via a coupling agent. A vibration damping device is designed at the bottom to reduce mechanical loss.
Cleaning Tank
Material: Primarily stainless steel (304/316L), offering both corrosion resistance and high strength. Some laboratory equipment utilizes polypropylene (PP) or polytetrafluoroethylene (PTFE) to accommodate specialized media.
Structural Design: A double-layer stainless steel tank with a vibration damping layer or internal ultrasonic radiation surfaces optimizes the sound wave propagation path and enhances cavitation uniformity.
Auxiliary Systems
Temperature Control and Heating Module
Built-in electric heating tubes or titanium alloy coils maintain the cleaning fluid temperature (typically 30-80°C) through steam/electric heating. Some industrial models support temperatures up to 100°C. Integrated high-precision temperature sensors and a PLC provide constant temperature control and over-temperature protection.
Circulating Filtration System
Filtration Component: Equipped with PP filter bags (1-50μm precision) or activated carbon adsorption modules, it removes suspended particles and organic matter in stages.
Circulating Pump: A corrosion-resistant magnetic pump drives the tank fluid flow, combined with sealed piping to prevent leaks and reduce sediment accumulation.
Safety and Control System
Protective Design: The tank cover is equipped with a splash-proof seal and a pressure relief valve to prevent liquid splashing or abnormal pressure.
Monitoring Module: A liquid level sensor, leakage protection device, and emergency stop function are integrated to ensure safe operation.
Other Key Components
Suspension and Fixtures
A patented tilting bracket or spiral groove design prevents direct contact between the workpiece and the tank bottom, minimizing blind spots. Customizable fixtures accommodate complex workpieces (such as camshafts and pipes) to ensure uniform ultrasonic energy coverage.
Chamber and Support Structure
The external chamber is constructed of steel plates or a corrosion-resistant frame, with built-in vibration damping material to reduce noise (≤65dB on some models). The panel integrates the operating interface, including an ammeter, power switch, and frequency adjustment knob.
