Ultrasonic cleaning machine is a widely used cleaning equipment in industrial and laboratory environments, which uses ultrasonic vibration to clean various objects, such as parts, utensils, and samples. However, when we start the ultrasonic cleaning machine, we usually hear some noise. This article will explore why ultrasonic cleaning machines emit noise after startup and the possible reasons for these noises.

超聲波清洗機的核心部件之一是超聲波換能器，它產生高頻超聲波振動。當振蕩器工作時，它會產生機械振動，這些振動會傳播到液體中，從而產生超聲波波動。這些振動會導致清洗機產生噪音，通常是一種高頻的嗡嗡聲。

One of the core components of an ultrasonic cleaning machine is an ultrasonic transducer, which generates high-frequency ultrasonic vibration. When the oscillator operates, it generates mechanical vibrations that propagate into the liquid, resulting in ultrasonic waves. These vibrations can cause noise in the cleaning machine, usually a high-frequency buzzing sound.

清洗過程中，液體中可能會產生氣泡。這些氣泡在液體中移動時會與物體表面發生碰撞，產生小的爆破聲。這些聲音可能會增加整體的噪音水平。

During the cleaning process, bubbles may be generated in the liquid. When these bubbles move in the liquid, they collide with the surface of the object, producing a small explosion sound. These sounds may increase the overall noise level.

清洗液體的性質也會影響清洗機的噪音水平。不同的清洗液體具有不同的粘度和密度，這會影響超聲波傳播和聲音的產生。一些清洗液體可能會產生更多的噪音，而另一些則會減少噪音水平。

The nature of the cleaning fluid can also affect the noise level of the cleaning machine. Different cleaning liquids have different viscosities and densities, which can affect the propagation of ultrasound and the generation of sound. Some cleaning liquids may produce more noise, while others may reduce noise levels.

超聲波清洗機的設計和質量也會影響噪音水平。高質量的清洗機通常采用隔音材料和減振技術，以減少噪音的傳播。因此，選擇合適的清洗機和進行適當的維護也可以降低噪音問題。

The design and quality of ultrasonic cleaning machines can also affect noise levels. High quality cleaning machines typically use soundproofing materials and vibration reduction technology to reduce the spread of noise. Therefore, selecting a suitable cleaning machine and performing appropriate maintenance can also reduce noise issues.

超聲波清洗機在啟動后會產生一定的噪音，這是由于超聲波換能器、氣泡、物體之間的摩擦以及清洗液體的性質等多種因素相互作用所致。雖然這些噪音可能有些許不便，但它們通常是正常的，不會影響清洗效果。

After starting, an ultrasonic cleaning machine will produce a certain amount of noise, which is caused by the interaction of various factors such as ultrasonic transducers, bubbles, friction between objects, and the properties of the cleaning liquid. Although these noises may be a bit inconvenient, they are usually normal and do not affect the cleaning effect.
