With its good cleaning performance, ultrasonic cleaning machine is now recognized and used by many customers. At present, it is used in many industries to help customers solve cleaning problems.

但目前也有很多客户对超声波清洗机接触还是比较少，会产生一定的误区：超声波的频率跟功率是不是越大，清洗效果越好？其实不是这样的。今天来讲解下有关超声波清洗机的频率跟功率问题。

However, at present, many customers still have little contact with the ultrasonic cleaning machine, which will lead to some misunderstandings: is the greater the ultrasonic frequency and power, the better the cleaning effect? Not really. Today, let's talk about the frequency and power of ultrasonic cleaning machine.

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。

Low frequency: ultrasonic cavitation threshold is closely related to frequency. The higher the frequency, the higher the cavitation threshold, and the lower the frequency. The lower the cavitation threshold, the easier it is to produce cavitation, which is conducive to cleaning, but it is easy to damage and corrode the workpiece surface. Therefore, the workpiece with higher requirements on the workpiece surface is not suitable to choose a lower frequency. Low frequency ultrasonic cleaning is generally suitable for large workpiece surface or when the adhesion between dirt and workpiece surface is high. The lower the frequency, the stronger the cavitation, and the higher the noise.

高频率：高频率的超声波穿透力较强，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。

High frequency: high frequency ultrasonic has strong penetration, and it is suitable to clean workpieces with high surface finish requirements or workpieces with complex surface, blind holes and many fine cracks. The noise of high-frequency ultrasonic is also low, which is suitable for cleaning some precision workpieces, such as semiconductors, aircraft precision workpieces, etc.

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。

Economy: considering the effect and economy of ultrasonic cleaning, the frequency is generally 20 ~ 130KHz, and the specific frequency should be determined by 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 large, the cavitation intensity in the liquid will be greatly increased, which is easy to cause cavitation corrosion on the surface of the workpiece, causing unnecessary loss and consumption to the workpiece. At the same time, the vibrating 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洗污垢，也是不可取的。

However, the choice of ultrasonic cleaning power is small, and it takes a long time to clean the dirt, which is also undesirable.

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 the industry, the standard ultrasonic cleaning machine ranges from 100W to 1500W. The size of the workpiece depends on the size of the ultrasonic cleaning tank on the premise of considering the cleaning beat.

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。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. If the power of ultrasonic cleaning machine is too large and the cleaning force is too strong, the damage to the workpiece surface will be stronger. For objects with fragile surface, the power needs to be carefully considered. The higher the power, the higher the price. Therefore, do not blindly pursue high power, and consider it from the perspective of economy and practicality.
