頻率是選擇超聲波清洗機的一大因素，頻率也決定了清洗力度。一般的來講，清洗五金、機械、汽摩、壓縮機等行業(yè)的清洗多采用28KHZ頻率的清洗機。光學光電子清洗、線路板清洗等多采用40KHZ的頻率。
Frequency is a major factor in the selection of ultrasonic cleaning machine, and it also determines the cleaning strength. Generally speaking, the cleaning machine with frequency of 28KHZ is mostly used for cleaning hardware, machinery, automobile, motorcycle, compressor and other industries. Optical optoelectronic cleaning, circuit board cleaning, etc. mostly use the frequency of 40KHZ.
這是一個錯誤的說法，而結果恰恰相反，頻率越低清洗力度反而更強，清洗效果也更好。不過具體還是看清洗物品，對于大部分產品而言40Khz頻率即夠了。
This is a wrong statement, but the result is just the opposite. The lower the frequency, the stronger the cleaning force, and the better the cleaning effect. However, it depends on the cleaning items. For most products, 40Khz frequency is enough.

在28khz低頻情況下，清洗的液體受到壓縮與稀疏作用的時間間隔更長，使氣泡能生長到更大尺寸，對清洗工件表面作用力更強。所以一般大型部件表面或者污物與工件表面結合度較高會選擇低頻超聲波清洗機，但是低頻比較容易損傷腐蝕工件表面，所以對那些表面要求較高的零件不宜選擇較低的頻率。
Under the low frequency of 28 khz, the time interval between the compressed and sparse action of the cleaning liquid is longer, so that the bubble can grow to a larger size, and the force on the surface of the cleaning workpiece is stronger. Therefore, generally, low-frequency ultrasonic cleaning machine will be selected when the surface of large parts or the combination of dirt and workpiece surface is high, but low-frequency is easy to damage and corrode the workpiece surface, so it is not appropriate to select a lower frequency for those parts with high surface requirements.
大家都知道超聲波清洗機的基本原理是基于液體的空化效應，事實上空化效應的強度直接跟頻率有關，頻率越高，空化氣泡越小，空化強度越弱。而且高頻穿透力強，適合清洗精密零件，比如電子零件、磁性材料、小型軸承加工;那些集成電路芯片、硅片鍍膜的則用更高的頻率超聲波清洗機;像那些機動車輛的發(fā)動機、閥門等大工件一般則用低頻率超聲波清洗機清洗，而市場用的比較適中的頻率是40KHZ。
As we all know, the basic principle of ultrasonic cleaning machine is based on the cavitation effect of liquid. In fact, the intensity of cavitation effect is directly related to the frequency. The higher the frequency is, the smaller the cavitation bubble is, and the weaker the cavitation intensity is. And high frequency penetration is strong, suitable for cleaning precision parts, such as electronic parts, magnetic materials, small bearing processing; Those with integrated circuit chip and silicon chip coating use higher frequency ultrasonic cleaning machine; Large workpieces such as engines and valves of motor vehicles are generally cleaned with low-frequency ultrasonic cleaners, while the moderate frequency used in the market is 40KHZ.
