Is Ultrasonic Cleaning Machine Harmful To Human Body?

Many people who first contact or operate ultrasonic cleaning machines for a long time will be more interested in the answer to this question. Today, we will discuss whether ultrasonic cleaning machine can cause harm to human body.

The principle of ultrasonic cleaning machine is to use the cavitation effect and secondary effect of ultrasonic wave in the liquid, such as DC water inflow acceleration and mechanical thermal effect, to directly or indirectly act on the cleaning workpiece and peel off the dirt on the workpiece, so as to achieve the purpose of high cleaning. Because ultrasound is not a secondary sound wave, it has high frequency, good directivity, strong penetration ability, strong media effect, no ionic radiation crisis, and has little impact on the human body. The best example is that the medical ultrasonic diagnosis and treatment equipment also adopts the ultrasonic principle, which also proves that ultrasound is harmless.

Although people can't hear the ultrasonic, some secondary effects in the ultrasonic cleaning process, such as the hissing sound generated by the mechanical effect on the stainless steel cleaning tank, make people uncomfortable. In particular, the high-power low-frequency ultrasonic cleaning equipment has relatively large noise. Staying around the working equipment for a long time will have a certain impact on hearing and may make people irritable. Especially pregnant women should not operate the ultrasonic cleaning machine.
