超聲波頻率的選擇：

Selection of ultrasonic frequency:

低頻率：超聲波空化閥值與頻率有密切關(guān)系。頻率越高，空化閥值越高，頻率低，空化閥值越低，越容易產(chǎn)生空化，有利于清洗作用，但易損傷腐蝕工件表面，因此對工件表面要求較高的工件不適合選擇較低的頻率，低頻超聲波清洗機(jī)一般適用于大型工件表面或者污物與工件表面粘合度高的情況下使用。而頻率越低，空化越強(qiáng)烈，產(chǎn)生的噪音也相應(yīng)偏大。高頻率：高頻率的工業(yè)超聲波清洗機(jī)穿透力較強(qiáng)，宜清洗工件表面光潔度要求較高或表面復(fù)雜盲孔，細(xì)縫較多的工件。高頻超聲波的噪音也偏小，適合于清洗一些精密工件，比如半導(dǎo)體，飛機(jī)精密工件等。經(jīng)濟(jì)性：從超聲波清洗效果及經(jīng)濟(jì)性來考慮，一般選取頻率在20~130KHz，具體選擇頻率應(yīng)做相應(yīng)的實(shí)驗(yàn)來確定。

Low frequency: The ultrasonic cavitation threshold is closely related to the frequency. The higher the frequency, the higher the cavitation threshold. The lower the frequency, the lower the cavitation threshold, and the easier it is to produce cavitation, which is beneficial for cleaning. However, it is easy to damage and corrode the surface of the workpiece. Therefore, workpieces with high surface requirements are not suitable for selecting lower frequencies. Low frequency ultrasonic cleaning machines are generally suitable for large workpiece surfaces or situations where the adhesion between dirt and workpiece surfaces is high. The lower the frequency, the stronger the cavitation, and the corresponding higher the noise generated. High frequency: Industrial ultrasonic cleaning machines with high frequency have strong penetration power, and are suitable for cleaning workpieces with high surface smoothness requirements or complex blind holes and numerous fine seams on the surface. The noise of high-frequency ultrasound is also relatively low, suitable for cleaning some precision workpieces, such as semiconductors, aircraft precision workpieces, etc. Economy: From the perspective of ultrasonic cleaning effect and economy, the frequency is generally selected between 20~130KHz, and the specific frequency selection should be determined through corresponding experiments.

超聲波功率的選擇：

Selection of ultrasonic power:

超聲波功率太大，液體中空化強(qiáng)度就會大大增加，容易使工件表面受到空化腐蝕，給工件造成不必要的損失跟消耗，同時(shí)清洗槽底部振動板也會受到空化腐蝕影響，使清洗槽的壽命縮短。

If the ultrasonic power is too high, the cavitation intensity in the liquid will greatly increase, which is easy to cause cavitation corrosion on the surface of the workpiece, causing unnecessary losses and consumption to the workpiece. At the same time, the vibration plate at the bottom of the cleaning tank will also be affected by cavitation corrosion, shortening the service life of the cleaning tank.

但超聲波清洗功率選擇小了，花費(fèi)很長時(shí)間也沒有清除污垢，也是不可取的。

However, it is not advisable to choose a low ultrasonic cleaning power, which takes a long time and does not remove dirt.

常規(guī)的超聲波清洗在工業(yè)當(dāng)中，標(biāo)準(zhǔn)型超聲波清洗機(jī)從100W至1500W不等，工件有多大，在考慮清洗節(jié)拍的前提下，由超聲波清洗槽體的大小決定超聲波的功率。

Conventional ultrasonic cleaning in industry, standard ultrasonic cleaning machines range from 100W to 1500W. The size of the workpiece is determined by the size of the ultrasonic cleaning tank, taking into account the cleaning rhythm.

以上。超聲波清洗機(jī)功率過大，清洗力度過強(qiáng)，對工件表面的損害性會越強(qiáng)，對于表面較脆弱的物體，需要謹(jǐn)慎考慮功率的大小。最后，功率越大，價(jià)格自然也越高，因此不要盲目追求大功率，應(yīng)從經(jīng)濟(jì)實(shí)用的角度來考慮。

Above. The ultrasonic cleaning machine has excessive power and cleaning force, which can cause greater damage to the surface of the workpiece. For objects with fragile surfaces, careful consideration should be given to the size of the power. Finally, the higher the power, the higher the price naturally. Therefore, do not blindly pursue high power, but consider from an economic and practical perspective.
