大家在选购超声波清洗机的时候都会注意到一个参数，那就是频率。超声波清洗机的频率种类很多，比如25kHz、30kHz、50kHz等。那么在选择的时候选择哪一频率的更好呢？不同频率有什么区别？为了方便解读，本文中将频率较高的超声波称为高频超声波，同理，频率较低的超声波称为低频超声波。

启航彩When choosing an ultrasonic cleaning machine, everyone will pay attention to a parameter, which is frequency. There are many types of frequencies for ultrasonic cleaning machines, such as 25kHz, 30kHz, 50kHz, etc. So when choosing, which frequency is better to choose? What is the difference between different frequencies? For the convenience of interpretation, high-frequency ultrasound is referred to as high-frequency ultrasound in this article, and similarly, low-frequency ultrasound is referred to as low-frequency ultrasound.

　　当我们看到25000Hz、30000Hz、50000Hz这些参数的时候，大概率会先入为主的认为频率越高也就也好。事实上就清洗效果而言，高频的反而没有低频的清洗效果好。

启航彩When we see parameters such as 25000Hz, 30000Hz, and 50000Hz, we are likely to assume that the higher the frequency, the better. In fact, in terms of cleaning effect, high-frequency cleaning is not as effective as low-frequency cleaning.

　　当然，我说的是相对而言，并不是说高频超声波的清洗效果就不好。低频清洗机的应用范围主要是清洗眼镜、表带、首饰等物件，适合精密清洗。而低频的超声波则适合大一点的、材质比较粗糙不怕损伤的物件，比如工业中的一些金属工件等。

启航彩Of course, what I'm saying is relatively speaking, not that the cleaning effect of high-frequency ultrasound is not good.. Its main application range is to clean items such as glasses, watch straps, jewelry, etc., suitable for precision cleaning. Low frequency ultrasound is suitable for larger, rough materials that are not afraid of damage, such as some metal workpieces in industry.

启航彩　　低频超声波的空化效应更强，能量更大，清洗效果更好，但是对被清洗物的伤害也更大；

启航彩The cavitation effect of low-frequency ultrasound is stronger, with greater energy and better cleaning effect, but it also causes greater damage to the cleaned object;

　　高频超声波的空化效应较弱，清洗效果相对较弱，但是对物件伤害较小，适合精密的物品清洗。

The cavitation effect of high-frequency ultrasound is relatively weak, and the cleaning effect is relatively weak, but it causes less damage to objects and is suitable for precision item cleaning.

启航彩　　所以在选择超声波清洗机的时候，应该根据被清洗物来选择。很多单频的超声波清洗机的频率都是在40kHz左右，因为这是一个很适中的频段，适合生产生活中的大多数情形使用。

So when choosing an ultrasonic cleaning machine, it should be based on the object being cleaned. Many single frequency ultrasonic cleaning machines have a frequency of around 40kHz, as this is a very moderate frequency band suitable for most situations in production and daily life.
