Ultra precision cleaning includes the ultra precision cleaning of mechanical parts, electronic components, optical components, etc. in precision industrial production processes, with the aim of removing extremely small dirt particles.

超声波清洗机根据清洗方法的不同，也可以分为物理清洗和化学清洗：利用力学、声学、光学，电学、热学的原理，依靠外来能量的作用，如机械摩擦、超声波、负压、高压.)中击。紫外线、蒸汽等去除物体表面污垢的方法叫物理清洗;依靠化学反应的作用，利用化学药品或其它溶剂去除物体表面污垢的方法叫化学清洗.如用各种无机或有机酸去除物体表面的锈迹、水垢，用氧化剂去除物体表面的色斑。剂杀灭微生物并去除霉斑等.物理清洗和化学清洗都存在着各自的优缺点，又具有很好的互补性。在实际应用过程中，通常都是把两者结合起来使用，以获得较好的清洗效果。

Ultrasonic cleaning machines can also be divided into physical cleaning and chemical cleaning according to different cleaning methods: using the principles of mechanics, acoustics, optics, electricity, and heat, relying on the action of external energy, such as mechanical friction, ultrasound, negative pressure, and high pressure Hit. The methods of removing surface dirt such as ultraviolet radiation and steam are called physical cleaning; The method of using chemicals or other solvents to remove dirt on the surface of an object through the action of chemical reactions is called chemical cleaning. For example, using various inorganic or organic acids to remove rust and scale on the surface of the object, and using oxidants to remove color spots on the surface of the object. Disinfectants kill microorganisms and remove mold spots. Both physical and chemical cleaning have their own advantages and disadvantages, and they also have good complementarity. In practical applications, the two are usually combined to achieve better cleaning results.

根据清洗媒介的不同，又可以分为湿式清洗和干式清洗：一般将在液体介质中进行的清洗称为湿式清洗，在气体介质中进行的清洗称为干式清洗.传统的清洗方式大多为湿式清洗，而人们比较容易理解的干式清洗也是吸尘器.但近年来，干式清洗发展迅速.如激光清洗.紫外线清洗，等离子清洗、干冰清洗等，在高。精，尖工业技术领域得到快速发展

According to the different cleaning media, it can be divided into wet cleaning and dry cleaning: generally, cleaning carried out in liquid media is called wet cleaning, and cleaning carried out in gas media is called dry cleaning. Traditional cleaning methods are mostly wet cleaning, while dry cleaning, which is more easily understood by people, is vacuum cleaners. However, in recent years, dry cleaning has developed rapidly, such as laser cleaning, ultraviolet cleaning, plasma cleaning Dry ice cleaning, etc., at high temperatures. Rapid development in the field of precision and cutting-edge industrial technology

超声波在液体中传播，使液体与清洗槽在超声波频率下一起振动，液体与清洗槽振动时有自己固有频率，这种振动频率是声波频率，所以人们听到嗡嗡声。随着清洗行业的不断发展，越来越多的行业和企业运用到了超声波清洗机。

Ultrasonic waves propagate in the liquid, causing the liquid and cleaning tank to vibrate together at the ultrasonic frequency. When the liquid and cleaning tank vibrate, they have their own inherent frequency, which is the frequency of sound waves, so people hear buzzing sounds. With the continuous development of the cleaning industry, more and more industries and enterprises are using ultrasonic cleaning machines.

对超声波清洗机原理由超声波发生器发出的高频振荡信号，通过换能器转换成高频机械振荡而传播到介质--清洗溶剂中，超声波在清洗液中疏密相间的向前辐射，使液体流动而产生数以万计的直径为50-500μm的微小气泡，存在于液体中的微小气泡在声场的作用下振动。这些气泡在超声波纵向传播的负压区形成、生长，而在正压区，当声压达到声压值时，气泡迅速增大，然后突然闭合。并在气泡闭合时产生冲击波，在其周围产生上千个大气压，破坏不溶性污物而使他们分散于清洗液中，当团体粒子被油污裹着而黏附在清洗件表面时，油被乳化，固体粒子及脱离，从而达到清洗件净化的目的。在这种被称之为“空化”效应的过程中，气泡闭合可形成几百度的高温和超过1000个气压的瞬间高压。

The principle of ultrasonic cleaning machine is that the high-frequency oscillation signal emitted by the ultrasonic generator is converted into high-frequency mechanical oscillation through a transducer and propagated to the medium - cleaning solvent. Ultrasonic waves radiate forward in the cleaning solution, causing the liquid to flow and producing tens of thousands of straight diameters ranging from 50 to 500 μ The tiny bubbles of m exist in liquid and vibrate under the action of sound field. These bubbles form and grow in the negative pressure zone where ultrasonic waves propagate longitudinally, while in the positive pressure zone, when the sound pressure reaches the sound pressure value, the bubbles rapidly increase and then suddenly close. And when the bubble closes, a shock wave is generated, generating thousands of atmospheres around it, damaging insoluble pollutants and dispersing them in the cleaning solution. When group particles are wrapped in oil and adhere to the surface of the cleaning part, the oil is emulsified, solid particles are separated, and the cleaning part is purified. In this process known as the "cavitation" effect, the closure of bubbles can form high temperatures of several hundred degrees Celsius and instantaneous high pressures exceeding 1000 atmospheric pressures.

超声波清洗机的优点是：超声波清洗效果好，操作简单。人们所听到的声音是频率20-20000Hz的声波信号，高于20000Hz的声波称之为超声波，声波的传递依照正弦曲线纵向传播，产生大量小气泡。一个原因是液体内局部出现拉应力而形成负压，压强的降低使原来溶于液体的气体过饱和，而从液体逸出，成为小气泡;另一原因是强大的拉应力把液体“撕开”成一空洞，称为空化。

The advantages of ultrasonic cleaning machine are: good cleaning effect and simple operation. The sound that people hear is a sound wave signal with a frequency of 20-20000Hz, and sound waves above 20000Hz are called ultrasonic waves. The transmission of sound waves propagates longitudinally along a sinusoidal curve, producing a large number of small bubbles. One reason is that tensile stress occurs locally within the liquid, resulting in negative pressure. The decrease in pressure causes the gas that was originally dissolved in the liquid to supersaturate and escape from the liquid, becoming small bubbles; Another reason is that the strong tensile stress "tears" the liquid into a cavity, known as cavitation.
