Ultrasonic cleaning is an efficient cleaning method that is widely used in various industries, especially when complex shapes, small pores and precision parts need to be cleaned. The following is a detailed principle of ultrasonic cleaning.

Principles of Ultrasonic Cleaning
Ultrasonic cleaning mainly relies on the propagation of ultrasonic waves in liquids, and usually includes the following key steps and principles:

Ultrasonic generation:
The transducer inside the ultrasonic cleaning machine converts electrical energy into ultrasonic energy, usually operating at a frequency between 20 kHz and 40 kHz.

Sound wave propagation:
Ultrasonic waves propagate in the cleaning liquid, forming high-frequency compression waves and rarefaction waves.

Cavitation phenomenon:
When sound waves propagate into the liquid, they cause periodic changes in the liquid pressure. At the moment of pressure reduction, tiny bubbles in the liquid form and expand rapidly, and then when the pressure increases again, these bubbles quickly collapse to form strong tiny shock waves.

Cleaning effect:
The shock waves and tiny eddies generated by the cavitation phenomenon effectively remove dirt, grease, dust and other contaminants from the surface of the workpiece, especially in hard-to-reach areas such as pores, gaps and complex shapes.
Liquid medium:
The choice of cleaning liquid is also very important. Commonly used cleaning liquids include deionized water, alcohol, detergents, etc. You can choose the appropriate liquid according to the nature of the cleaning object.
