超声波频率的选择：

Selection of ultrasonic frequency:

低频率：超声波空化阀值与频率有密切关系。频率越高，空化阀值越高，频率低，空化阀值越低，越容易产生空化，有利于清洗作用，但易损伤腐蚀工件表面，因此对工件表面要求较高的工件不适合选择较低的频率，低频超声波清洗机一般适用于大型工件表面或者污物与工件表面粘合度高的情况下使用。而频率越低，空化越强烈，产生的噪音也相应偏大。高频率：高频率的工业超声波清洗机穿透力较强，宜清洗工件表面光洁度要求较高或表面复杂盲孔，细缝较多的工件。高频超声波的噪音也偏小，适合于清洗一些精密工件，比如半导体，飞机精密工件等。经济性：从超声波清洗效果及经济性来考虑，一般选取频率在20~130KHz，具体选择频率应做相应的实验来确定。

Low frequency: The ultrasonic cavitation threshold is closely related to the frequency. The higher the frequency, the higher the cavitation threshold. The lower the frequency, the lower the cavitation threshold, and the easier it is to produce cavitation, which is beneficial for cleaning. However, it is easy to damage and corrode the surface of the workpiece. Therefore, workpieces with high surface requirements are not suitable for selecting lower frequencies. Low frequency ultrasonic cleaning machines are generally suitable for large workpiece surfaces or situations where the adhesion between dirt and workpiece surfaces is high. The lower the frequency, the stronger the cavitation, and the corresponding higher the noise generated. High frequency: Industrial ultrasonic cleaning machines with high frequency have strong penetration power, and are suitable for cleaning workpieces with high surface smoothness requirements or complex blind holes and numerous fine seams on the surface. The noise of high-frequency ultrasound is also relatively low, suitable for cleaning some precision workpieces, such as semiconductors, aircraft precision workpieces, etc. Economy: From the perspective of ultrasonic cleaning effect and economy, the frequency is generally selected between 20~130KHz, and the specific frequency selection should be determined through corresponding experiments.

超声波功率的选择：

Selection of ultrasonic power:

超声波功率太大，液体中空化强度就会大大增加，容易使工件表面受到空化腐蚀，给工件造成不必要的损失跟消耗，同时清洗槽底部振动板也会受到空化腐蚀影响，使清洗槽的寿命缩短。

If the ultrasonic power is too high, the cavitation intensity in the liquid will greatly increase, which is easy to cause cavitation corrosion on the surface of the workpiece, causing unnecessary losses and consumption to the workpiece. At the same time, the vibration plate at the bottom of the cleaning tank will also be affected by cavitation corrosion, shortening the service life of the cleaning tank.

但超声波清洗功率选择小了，花费很长时间也没有清除污垢，也是不可取的。

However, it is not advisable to choose a low ultrasonic cleaning power, which takes a long time and does not remove dirt.

常规的超声波清洗在工业当中，标准型超声波清洗机从100W至1500W不等，工件有多大，在考虑清洗节拍的前提下，由超声波清洗槽体的大小决定超声波的功率。

Conventional ultrasonic cleaning in industry, standard ultrasonic cleaning machines range from 100W to 1500W. The size of the workpiece is determined by the size of the ultrasonic cleaning tank, taking into account the cleaning rhythm.

以上。超声波清洗机功率过大，清洗力度过强，对工件表面的损害性会越强，对于表面较脆弱的物体，需要谨慎考虑功率的大小。最后，功率越大，价格自然也越高，因此不要盲目追求大功率，应从经济实用的角度来考虑。

Above. The ultrasonic cleaning machine has excessive power and cleaning force, which can cause greater damage to the surface of the workpiece. For objects with fragile surfaces, careful consideration should be given to the size of the power. Finally, the higher the power, the higher the price naturally. Therefore, do not blindly pursue high power, but consider from an economic and practical perspective.
