The principle of single groove industrial ultrasonic cleaning machine is to use the high frequency of ultrasonic wave to convert high-frequency kinetic energy through transducer, and then act on the liquid medium in the cleaning tank to make the liquid cavitate, continuously form countless tiny bubbles, and burst rapidly to produce impact force on the surface of the object, so as to separate the surface dirt, so as to achieve the cleaning effect. So how does it work? Before introducing this working principle, let's first understand what is ultrasound? Ultrasound is the number of vibrations per second scientists call the frequency of sound, and its unit is Hertz (Hz). The frequency of sound waves that our human ears can hear is 20Hz ~ 20000hz (20kHz). When the vibration frequency of sound wave is less than 20Hz or more than 20kHz, we can't hear it. Therefore, we call the sound wave whose frequency is higher than 20000 Hz "ultrasonic wave". Here, when many people use the industrial ultrasonic cleaning machine, they think it's the sound of ultrasonic when they hear the hum. In fact, it's just the sound of liquid cavitation.

            

單槽型工業超聲波清洗機上的超聲波頻率一般是28KHz以上。高可達128KHz以上，常用的是40KHz，這個頻率比較通用，適合大多數工件的清洗。頻率越低，清洗的細膩度就越低，但力度會強些。反之，則清洗的越精細，但力度會減弱。然后把這種頻率通過換能器又稱超聲波驅動電源、電子箱、超聲波控制器，是大功率超聲系統的重要組成部分。在高頻率的超聲波推動下，換能器以每秒數十萬次的頻率震動，這種震動傳遞到緊扣在上面的清洗槽上，透過清洗槽將動能傳遞到槽內的液體中。在這種高頻率的震動下，液體就會產生空化作用。

The frequency of ultrasonic wave on single groove industrial ultrasonic cleaning machine is generally above 28kHz. Up to 128khz, commonly used is 40KHz, this frequency is more common, suitable for most workpiece cleaning. The lower the frequency, the lower the fineness of cleaning, but the strength will be stronger. On the contrary, the more fine the cleaning, but the strength will be weakened. Then the frequency is passed through the transducer, also known as ultrasonic driving power supply, electronic box and ultrasonic controller, which is an important part of high-power ultrasonic system. Driven by high-frequency ultrasound, the transducer vibrates hundreds of thousands of times per second. This vibration is transmitted to the cleaning tank tightly above, through which kinetic energy is transferred to the liquid in the tank. In this high frequency vibration, the liquid will produce cavitation.
