Ultrasonic cleaning is a mechanical vibration cleaning method that utilizes high-frequency sound waves to propagate into the liquid, generating small bubbles and releasing energy during the explosion process, thus cleaning the surface of the object. This process is called the "cavitation effect" and includes the following steps:

声波传播：超声波波动通过超声波发生器和超声波换能器产生，并传播到液体中。这些声波波动以频率表示，通常以千赫兹（kHz）为单位。

Sound wave propagation: Ultrasonic waves are generated through ultrasonic generators and ultrasonic transducers and propagate into liquids. These sound waves are expressed in frequency, usually in kilohertz (kHz).

气泡形成：声波波动在液体中产生微小气泡，这些气泡形成于液体中的高压区域。

Bubble formation: Sound waves generate tiny bubbles in the liquid, which form in high-pressure areas of the liquid.

气泡爆破：气泡在高压区域中不断生长，然后突然破裂，释放出冲击力。

Bubble explosion: Bubbles continuously grow in high-pressure areas and then suddenly rupture, releasing impact force.

清洁作用：空化效应产生的冲击力将附着在物体表面的污垢剥离，从而实现清洁效果。

Cleaning effect: The impact force generated by the cavitation effect will peel off the dirt attached to the surface of the object, thereby achieving a cleaning effect.

适宜的超声波频率

Suitable ultrasonic frequency

超声波清洗的频率对清洁效果有显著的影响。不同的应用可能需要不同的频率，但通常，适宜的频率范围在20kHz到100kHz之间。下面是不同频率范围的一些特点：

The frequency of ultrasonic cleaning has a significant impact on the cleaning effect. Different applications may require different frequencies, but typically, the appropriate frequency range is between 20kHz and 100kHz. Here are some characteristics of different frequency ranges:

至40 kHz：低频率的超声波适用于较重的工业清洁任务，如去除焊接残留物、机械零件的清洁等。这些频率的超声波能够用于处理坚固的污垢。

Up to 40 kHz: Low frequency ultrasound is suitable for heavy industrial cleaning tasks, such as removing welding residues and cleaning mechanical parts. These frequencies of ultrasound can be used to treat sturdy dirt.

至80kHz：中频率的超声波适用于更广泛的应用，包括电子元件、眼镜、珠宝和医疗器械的清洁。这些频率提供了良好的平衡，可以去除表面污垢而不损害物体。

Up to 80kHz: Medium frequency ultrasound is suitable for a wider range of applications, including cleaning of electronic components, glasses, jewelry, and medical devices. These frequencies provide a good balance and can remove surface dirt without damaging the object.

至100kHz：高频率的超声波适用于精细清洁任务，如半导体制造和实验室用途。它们提供更细致的清洁，适用于清洗微小器件和精密部件。

Up to 100kHz: High frequency ultrasound is suitable for fine cleaning tasks such as semiconductor manufacturing and laboratory applications. They provide more detailed cleaning, suitable for cleaning small devices and precision components.

需要注意的是，超声波清洗的频率不仅影响清洁效果，还可能对被清洗物体造成损害。因此，在选择超声波频率时，必须谨慎考虑清洁对象的特性和材料。过高或过低的频率都可能导致清洁效果不佳或物体受损。

It should be noted that the frequency of ultrasonic cleaning not only affects the cleaning effect, but also may cause damage to the cleaned object. Therefore, when selecting the ultrasonic frequency, careful consideration must be given to the characteristics and materials of the cleaning object. Too high or too low a frequency can lead to poor cleaning performance or damage to objects.

超声波清洗是一种高效的清洁技术，其适宜频率取决于清洁任务的性质和被清洗物体的特性。理解超声波清洗的原理和不同频率范围的应用可以帮助确保清洁过程的成功。选择合适的频率将使清洁任务更加高效，同时确保被清洗物体不受损害。在实际应用中，应根据具体情况来选择合适的超声波频率，以获得佳的清洁效果。

Ultrasonic cleaning is an efficient cleaning technology, and its appropriate frequency depends on the nature of the cleaning task and the characteristics of the cleaned object. Understanding the principles of ultrasonic cleaning and the application of different frequency ranges can help ensure the success of the cleaning process. Choosing the appropriate frequency will make the cleaning task more efficient while ensuring that the cleaned object is not damaged. In practical applications, the most suitable ultrasonic frequency should be selected based on the specific situation to achieve the best cleaning effect.
