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.

超声波清洗机的核心部件之一是超声波换能器，它产生高频超声波振动。当振荡器工作时，它会产生机械振动，这些振动会传播到液体中，从而产生超声波波动。这些振动会导致清洗机产生噪音，通常是一种高频的嗡嗡声。

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.

清洗过程中，液体中可能会产生气泡。这些气泡在液体中移动时会与物体表面发生碰撞，产生小的爆破声。这些声音可能会增加整体的噪音水平。

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.

清洗液体的性质也会影响清洗机的噪音水平。不同的清洗液体具有不同的粘度和密度，这会影响超声波传播和声音的产生。一些清洗液体可能会产生更多的噪音，而另一些则会减少噪音水平。

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.

超声波清洗机的设计和质量也会影响噪音水平。高质量的清洗机通常采用隔音材料和减振技术，以减少噪音的传播。因此，选择合适的清洗机和进行适当的维护也可以降低噪音问题。

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.

超声波清洗机在启动后会产生一定的噪音，这是由于超声波换能器、气泡、物体之间的摩擦以及清洗液体的性质等多种因素相互作用所致。虽然这些噪音可能有些许不便，但它们通常是正常的，不会影响清洗效果。

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.
