在選擇多槽手動(dòng)超聲波清洗機(jī)過(guò)程中，重要的是為目標(biāo)材質(zhì)，污染物選擇合適的超聲波清洗頻率以及清洗功率？ 那么我們究竟應(yīng)該如何選擇多槽手動(dòng)超聲波清洗機(jī)的頻率和輸出功率呢？它們是多槽手動(dòng)超聲波清洗機(jī)的重要參數(shù)。關(guān)于超聲頻率，當(dāng)超聲波清洗中的頻率發(fā)生變化時(shí)，發(fā)生的空化核的大小會(huì)發(fā)生變化。當(dāng)超聲波頻率較低時(shí)，如28kHz，空化核的尺寸增大，大空化適合去除碳、垢、磨料、油漬等，這些需要很強(qiáng)的沖擊力和很強(qiáng)的力。 此外，它對(duì)大污漬（顆粒）有效。另一方面，頻率越高，氣蝕的幅度越小，清洗能力越小，但在精密零件清洗中，它比低頻的小污垢（顆粒清洗）更有效。

　　In the process of selecting a multi slot manual ultrasonic cleaning machine, it is important to choose the appropriate ultrasonic cleaning frequency and cleaning power for the target material and pollutants? So how should we choose the frequency and output power of the multi slot manual ultrasonic cleaning machine? They are important parameters of multi slot manual ultrasonic cleaning machines. When the frequency of ultrasound cleaning changes, the size of the cavitation nuclei will also change. When the ultrasonic frequency is low, such as 28kHz, the size of the cavitation nucleus increases, and large cavitation is suitable for removing carbon, scale, abrasives, oil stains, etc., which require strong impact and force. In addition, it is effective against large stains (particles). On the other hand, the higher the frequency, the smaller the amplitude of cavitation and the smaller the cleaning ability, but in precision parts cleaning, it is more effective than low-frequency small dirt (particle cleaning).

　　從超聲波空化損壞的角度選擇合適的超聲波頻率也很重要。 根據(jù)材料的不同，高沖擊力和低頻率有時(shí)會(huì)導(dǎo)致產(chǎn)品劃痕或裂紋。超聲波頻率是決定空化核大小的一個(gè)因素，產(chǎn)生的空化量由超聲波的功率和頻率決定。 正確選擇這兩個(gè)參數(shù)（頻率和功率）在超聲波清洗中非常重要。一些多槽手動(dòng)超聲波清洗機(jī)可以通過(guò)改變振動(dòng)頻率來(lái)處理各種污垢，但以各種方式切換頻率對(duì)于一定尺寸的污垢（顆粒）也很有效。 一般來(lái)說(shuō)，在28kHz和40kHz等低頻下進(jìn)行氣蝕清洗具有很強(qiáng)的沖擊力，因此對(duì)頑固污垢和厚層污垢有效。 另一方面，強(qiáng)大的沖擊力可能會(huì)損壞工件，因此在清洗玻璃基板或鏡頭時(shí)需要提前檢查。 在材料方面，要注意玻璃、陶瓷等易受沖擊而產(chǎn)生裂紋的工件，以及鋁、銅、金等軟金屬的表面劃痕。在這種情況下，波長(zhǎng)相對(duì)較短且沖擊力較弱的 80kHz 和132 kHz 等頻率是有效的。 但是，由于存在清洗力本身不足的可能性，因此在短時(shí)間內(nèi)使用40 kHz頻率，然后使用68 kHz、120 kHz、175 kHz等頻率以達(dá)到有效的清洗效果的情況并不少見。

　　It is also important to choose the appropriate ultrasonic frequency from the perspective of ultrasonic cavitation damage. Depending on the material, high impact force and low frequency can sometimes cause scratches or cracks on the product. The ultrasonic frequency is a factor that determines the size of cavitation nuclei, and the amount of cavitation generated is determined by the power and frequency of the ultrasonic waves. The correct selection of these two parameters (frequency and power) is crucial in ultrasonic cleaning. Some multi slot manual ultrasonic cleaning machines can treat various types of dirt by changing the vibration frequency, but switching frequencies in various ways is also effective for dirt (particles) of a certain size. Generally speaking, cavitation cleaning at low frequencies such as 28kHz and 40kHz has strong impact force, making it effective for stubborn dirt and thick layer dirt. On the other hand, strong impact forces may damage the workpiece, so it is necessary to check in advance when cleaning the glass substrate or lens. In terms of materials, attention should be paid to workpieces such as glass and ceramics that are prone to cracking due to impact, as well as surface scratches on soft metals such as aluminum, copper, and gold. In this case, frequencies such as 80kHz and 132 kHz, which have relatively short wavelengths and weak impact forces, are effective. However, due to the possibility of insufficient cleaning power itself, it is not uncommon to use a frequency of 40 kHz in a short period of time, and then use frequencies such as 68 kHz, 120 kHz, and 175 kHz to achieve effective cleaning results.

　　The standing wave phenomenon of ultrasound is the point where cavitation occurs in the wavelength band, because at each frequency, the negative pressure state is strongest at each half wavelength (1/4 and 3/4 wavelength parts of a wavelength). It can be said that the lower the frequency, the wider the interval between standing waves. In fact, there is a reflection effect on the workpiece and the wall, but if this standing wave is effectively utilized, effective cleaning can be carried out. However, for precision workpieces that are susceptible to impact forces, these parts with dense cavitation may cause fatal damage. When using water, the spacing between standing waves depends on the frequency used. It is approximately 18 mm at 40 kHz and 10 mm at 68 kHz. For other frequency wavelengths, please consult the Keli Ultrasonic Technology Department at 18588468367. Regarding the ultrasonic frequency and particle size removal rate in the cleaning of large and small particles, the particle removal effect is often strongly affected by the ultrasonic frequency. The tendency to select the effective frequency based on particle size is widely adopted, especially in the hard disk industry. 40kHz-10~30μ - 68kHz-5μ~20μ - 120kHz-3μ~10μ -175kHz-1~5μ、

　　多槽手動(dòng)超聲波清洗機(jī)功率：雖然超聲波頻率是決定空化幅度的一個(gè)因素，但超聲波的功率也是決定空化源和數(shù)量的重要因素。 特別是，初始輸出（選擇多少瓦的超聲波）取決于超聲波換能器的數(shù)量。 超聲波振子的數(shù)量取決于產(chǎn)生振動(dòng)的地方是多還是少（也就是輻射面積大小），如果輸出相對(duì)于該區(qū)域較低，則會(huì)導(dǎo)致清潔不均勻。 此外，由于液體的負(fù)荷，很難振動(dòng)，因此需要適當(dāng)選擇輸出。此外，Kelisonic超聲波發(fā)生器可以調(diào)節(jié)輸出大小，在這種調(diào)整中，超聲波振子的（振幅）的寬度（振幅）增大或減小。于它也是決定空化密度的一個(gè)因素，因此通過(guò)調(diào)整超聲波發(fā)生器的輸出來(lái)設(shè)置適當(dāng)?shù)妮敵鲆埠苤匾?/p>

　　Power of Multi slot Manual Ultrasonic Cleaning Machine: Although ultrasonic frequency is a factor determining the amplitude of cavitation, the power of ultrasonic waves is also an important factor determining the source and quantity of cavitation. Especially, the initial output (how many watts of ultrasonic waves to choose) depends on the number of ultrasonic transducers. The number of ultrasonic oscillators depends on whether the vibration is generated in more or less areas (i.e. the size of the radiation area). If the output is relatively low compared to that area, it will result in uneven cleaning. In addition, due to the load of the liquid, it is difficult to vibrate, so it is necessary to choose the output appropriately. In addition, the Kelisonic ultrasonic generator can adjust the output size, in which the width (amplitude) of the ultrasonic oscillator increases or decreases. It is also a factor that determines cavitation density, so it is important to adjust the output of the ultrasonic generator to set an appropriate output.
