一般來說超聲波清洗設備,其頻率應在20KHz-80KHz之間,頻率(lǜ)低噪音大,換(huàn)能器的體積也偏大。下麵來講(jiǎng)講
超聲波清洗機工(gōng)作頻率的重(chóng)要性吧。
Generally speaking, the frequency of ultrasonic cleaning equipment should be between 20KHz-80KHz. The frequency is low and the noise is high. The volume of the transducer is also large. Now let's talk about the importance of the working frequency of the ultrasonic cleaner.
當工作頻率很低(在人的聽覺範圍內)就會產生噪音。當頻(pín)率低於(yú)20kHz時,工作噪音不僅變(biàn)得很(hěn)大,而且可能超出職業安全與保健法(fǎ)或其他條(tiáo)例所規定(dìng)的安全噪音的(de)限度(dù)。
When the working frequency is very low (within the range of human hearing), noise will be generated. When the frequency is lower than 20kHz, the working noise not only becomes very large, but also may exceed the limit of safe noise stipulated by the Occupational Safety and Health Care Act or other regulations.
在需要高功率去除汙(wū)垢而不用考慮工件表麵損傷的應用中,通常選擇從20kHz到30kHz範圍內的較低清洗頻率。該頻(pín)率範圍內的清洗(xǐ)頻率常常被用於清(qīng)洗大型、重型零件(jiàn)或高密度材料的(de)工件。20KHz的磁力換能器和25KHz的壓電(diàn)換能器。
In applications where high power is required to remove dirt without considering the surface damage of the workpiece, a lower cleaning frequency from 20kHz to 30kHz is usually selected. The cleaning frequency within this frequency range is often used to clean large, heavy parts or workpieces made of high-density materials. 20KHz magnetic transducer and 25KHz piezoelectric transducer.
高頻通常被用於清洗較小、較(jiào)好的零件,或清(qīng)除微小顆粒。高頻還被用於被工件表麵不允許損(sǔn)傷的應用。使用高頻可從幾個(gè)方麵改善(shàn)清洗性能。
High frequency is usually used to clean smaller and better parts or remove small particles. High frequency is also used in applications where the surface of the workpiece is not allowed to be damaged. Using high frequency can improve cleaning performance in several ways.

隨著頻率的增加,空化泡的數量呈線形增加,從而產生更多更密(mì)集(jí)的衝擊波使其能進入到(dào)更小的縫隙中。
With the increase of frequency, the number of cavitation bubbles increases linearly, so that more and more intensive shock waves can be generated and they can enter into smaller gaps.
如果功率保持不變,空化泡變小,其釋放的能量相應減少,這樣有效地減小了對工件表麵的損傷。高頻的另一個優勢(shì)在於減(jiǎn)小了粘滯邊界層(泊努裏效(xiào)應),使得超聲波能夠發現細小的微(wēi)粒。這種情況近似於小溪中水位降低時可以看清溪底的(de)小石子。
If the power remains unchanged, the cavitation bubble becomes smaller, and the released energy decreases accordingly, which effectively reduces the damage to the workpiece surface. Another advantage of high frequency is that it reduces the viscous boundary layer (Bernoulli effect), enabling ultrasound to detect small particles. This situation is similar to the small stones at the bottom of the stream when the water level in the stream drops.
