Application Cases

With the advancement of technology, the cleaning industry has expanded into daily cleaning, industrial automation, automotive manufacturing, mechanical engineering, aerospace, shipbuilding, and electronics manufacturing. Today, the demand for cleaning continues to grow, and its applications are diversifying. Traditional cleaning methods often fall short when it comes to precision industrial equipment, as physical contact can cause damage and affect the accuracy of sensitive instruments. This has created an urgent need for innovative cleaning technologies. Ultrasonic cleaning has rapidly gained traction due to its high quality, efficiency, non-polluting nature, ease of automation, and adaptability to complex surface geometries, making it widely applicable in both daily life and industrial cleaning.

Aigtek's ATA-4000 series high-voltage power amplifiers are extensively used in non-destructive testing applications. With a maximum output voltage of 310 Vpp and a -3 dB bandwidth of DC to 3 MHz, they are capable of driving most ultrasonic transducers.

Experiment Name: Impurity and Metal Removal Experiment Based on Ultrasonic Cleaning

Experimental Principle:
Ultrasonic cleaning utilizes transducers to convert electrical energy into mechanical vibrations. These vibrations are transmitted through the walls of the cleaning tank to the cleaning solution inside. Under the influence of ultrasonic waves, microscopic bubbles in the liquid undergo sustained vibration, achieving the purpose of cleaning.

Experimental Process:
A signal generator outputs a 40 kHz sinusoidal signal with an amplitude of 3 Vpp, which is fed into an ATA-4051 high-voltage power amplifier. After amplification, the amplifier outputs a 300 Vpp voltage signal to drive the ultrasonic transducer, generating ultrasonic waves. The cavitation effect produced by ultrasonic vibration is used to remove sludge from the metal surface.

Experimental Results:
When ultrasonic waves irradiate the cleaning solution, microscopic bubbles begin to vibrate under the influence of the sound waves. It is clearly observed that the sludge on the metal surface is effectively removed. This frequency range is suitable for rough, heavy, and initial cleaning of metal components.

Role of the Power Amplifier:
The power amplifier serves as the core component of the entire experiment, providing a high-stability, low-distortion AC signal in the range of 200–300 Vpp to drive the ultrasonic transducer.

Recommended Power Amplifier: ATA-4000 Series High-Voltage Power Amplifier
