一般来说超声波清洗设备，其频率应在20KHz-80KHz之间，频率低噪音大，换能器的体积也偏大。下面来讲讲超声波清洗机工作频率的重要性吧。

Generally speaking, the frequency of ultrasonic cleaning equipment should be between 20KHz-80KHz. The frequency is low and the noise is high. The volume of the transducer is also large. Now let's talk about the importance of the working frequency of the ultrasonic cleaner.

当工作频率很低(在人的听觉范围内)就会产生噪音。当频率低於20kHz时，工作噪音不仅变得很大，而且可能超出职业与保健法或其他条例所规定的噪音的限度。

When the working frequency is very low (within the range of human hearing), noise will be generated. When the frequency is lower than 20kHz, the working noise not only becomes very large, but also may exceed the limit of safe noise stipulated by the Occupational Safety and Health Care Act or other regulations.

在需要高功率去除污垢而不用考虑工件表面损伤的应用中，通常选择从20kHz到30kHz范围内的较低清洗频率。该频率范围内的清洗频率常常被用於清洗大型、重型零件或高密度材料的工件。20KHz的磁力换能器和25KHz的压电换能器。

In applications where high power is required to remove dirt without considering the surface damage of the workpiece, a lower cleaning frequency from 20kHz to 30kHz is usually selected. The cleaning frequency within this frequency range is often used to clean large, heavy parts or workpieces made of high-density materials. 20KHz magnetic transducer and 25KHz piezoelectric transducer.

高频通常被用於清洗较小、较好的零件，或微小颗粒。高频还被用於被工件表面不允许损伤的应用。使用高频可从几个方面改善清洗性能。

High frequency is usually used to clean smaller and better parts or remove small particles. High frequency is also used in applications where the surface of the workpiece is not allowed to be damaged. Using high frequency can improve cleaning performance in several ways.

随着频率的增加，空化泡的数量呈线形增加，从而产生更多更密集的冲击波使其能进入到更小的缝隙中。

With the increase of frequency, the number of cavitation bubbles increases linearly, so that more and more intensive shock waves can be generated and they can enter into smaller gaps.

如果功率保持不变，空化泡变小，其释放的能量相应减少，这样有效地减小了对工件表面的损伤。高频的另一个优势在於减小了粘滞边界层(泊努里效应)，使得超声波能够发现细小的微粒。这种情况近似於小溪中水位降低时可以看清溪底的小石子。

If the power remains unchanged, the cavitation bubble becomes smaller, and the released energy decreases accordingly, which effectively reduces the damage to the workpiece surface. Another advantage of high frequency is that it reduces the viscous boundary layer (Bernoulli effect), enabling ultrasound to detect small particles. This situation is similar to the small stones at the bottom of the stream when the water level in the stream drops.
