单槽型工业超声波清洗机原理是利用超声波的高频率，通过换能器转化为高频动能，然后作用于清洗槽中的液体介质，使液体产生空化作用，不断的形成无数个细微气泡，并迅速爆裂，产生冲击力冲击物件表面，使表面污垢脱离，从而达到清洗的效果。那么具体是怎么工作的呢？在介绍这个工作原理之前，我们先来了解一下，什么是超声波？超声波是科学家们将每秒钟振动的次数称为声音的频率，它的单位是赫兹(hz)。我们人类耳朵能听到的声波频率为20hz～20000hz(20khz)。当声波的振动频率小于20hz或大于20khz时，我们便听不见了。因此，我们把频率高于20000赫兹的声波称为“超声波”。这里说明下，许多人在使用工业超声波清洗机时，听到嗡嗡声，就以为是超声波发出的声音，其实那只是液体在空化作用下产生的声音。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.
单槽型工业超声波清洗机上的超声波频率一般是28khz以上。高可达128khz以上，常用的是40khz，这个频率比较通用，适合大多数工件的清洗。频率越低，清洗的细腻度就越低，但力度会强些。反之，则清洗的越精细，但力度会减弱。然后把这种频率通过换能器又称超声波驱动电源、电子箱、超声波控制器，是大功率超声系统的重要组成部分。在高频率的超声波推动下，换能器以每秒数十万次的频率震动，这种震动传递到紧扣在上面的清洗槽上，透过清洗槽将动能传递到槽内的液体中。在这种高频率的震动下，液体就会产生空化作用。
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.
