大家在選購超聲波清洗機的時候都會注意到一個參數，那就是頻率。超聲波清洗機的頻率種類很多，比如25kHz、30kHz、50kHz等。那么在選擇的時候選擇哪一頻率的更好呢？不同頻率有什么區別？為了方便解讀，本文中將頻率較高的超聲波稱為高頻超聲波，同理，頻率較低的超聲波稱為低頻超聲波。

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.

　　當我們看到25000Hz、30000Hz、50000Hz這些參數的時候，大概率會先入為主的認為頻率越高也就也好。事實上就清洗效果而言，高頻的反而沒有低頻的清洗效果好。

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.

　　當然，我說的是相對而言，并不是說高頻超聲波的清洗效果就不好。低頻清洗機的應用范圍主要是清洗眼鏡、表帶、首飾等物件，適合精密清洗。而低頻的超聲波則適合大一點的、材質比較粗糙不怕損傷的物件，比如工業中的一些金屬工件等。

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.

　　低頻超聲波的空化效應更強，能量更大，清洗效果更好，但是對被清洗物的傷害也更大；

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;

　　高頻超聲波的空化效應較弱，清洗效果相對較弱，但是對物件傷害較小，適合精密的物品清洗。

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.

　　所以在選擇超聲波清洗機的時候，應該根據被清洗物來選擇。很多單頻的超聲波清洗機的頻率都是在40kHz左右，因為這是一個很適中的頻段，適合生產生活中的大多數情形使用。

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.
