在选择多槽手动超声波清洗机过程中，重要的是为目标材质，污染物选择合适的超声波清洗频率以及清洗功率？ 那么我们究竟应该如何选择多槽手动超声波清洗机的频率和输出功率呢？它们是多槽手动超声波清洗机的重要参数。关于超声频率，当超声波清洗中的频率发生变化时，发生的空化核的大小会发生变化。当超声波频率较低时，如28kHz，空化核的尺寸增大，大空化适合去除碳、垢、磨料、油渍等，这些需要很强的冲击力和很强的力。 此外，它对大污渍（颗粒）有效。另一方面，频率越高，气蚀的幅度越小，清洗能力越小，但在精密零件清洗中，它比低频的小污垢（颗粒清洗）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).

　　从超声波空化损坏的角度选择合适的超声波频率也很重要。 根据材料的不同，高冲击力和低频率有时会导致产品划痕或裂纹。超声波频率是决定空化核大小的一个因素，产生的空化量由超声波的功率和频率决定。 正确选择这两个参数（频率和功率）在超声波清洗中非常重要。一些多槽手动超声波清洗机可以通过改变振动频率来处理各种污垢，但以各种方式切换频率对于一定尺寸的污垢（颗粒）也很有效。 一般来说，在28kHz和40kHz等低频下进行气蚀清洗具有很强的冲击力，因此对顽固污垢和厚层污垢有效。 另一方面，强大的冲击力可能会损坏工件，因此在清洗玻璃基板或镜头时需要提前检查。 在材料方面，要注意玻璃、陶瓷等易受冲击而产生裂纹的工件，以及铝、铜、金等软金属的表面划痕。在这种情况下，波长相对较短且冲击力较弱的 80kHz 和132 kHz 等频率是有效的。 但是，由于存在清洗力本身不足的可能性，因此在短时间内使用40 kHz频率，然后使用68 kHz、120 kHz、175 kHz等频率以达到有效的清洗效果的情况并不少见。

　　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.

　　超声波的驻波现象是波段中发生空化的点，因为在每个频率下，负压状态在每个半波长（一个波长的 1/4 和 3/4 波长部分）处最强。 可以说频率越低，驻波之间的间隔越宽。 实际上，工件和壁面上有反射效应，但如果有效地利用这种驻波，就可以进行有效的清洁。 然而，对于易受冲击力影响的精密工件，这种气蚀致密的零件可能会造成致命的损坏。使用水时，驻波之间的间隔取决于使用的频率，在 40 kHz 时约为 18 mm，在 68kHz 时约为 10 mm，其它频率波长请咨询科力超声技术部18588468367。关于颗粒大下小清洗中的超声波频率和颗粒度去除率，颗粒去除效果往往受到超声波频率的强烈影响，根据粒径选择有效频率的倾向被广泛采用，特别是在硬盘行业。40kHz-10~30μ - 68kHz-5μ~20μ - 120kHz-3μ~10μ -175kHz-1~5μ、

　　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、

　　多槽手动超声波清洗机功率：虽然超声波频率是决定空化幅度的一个因素，但超声波的功率也是决定空化源和数量的重要因素。 特别是，初始输出（选择多少瓦的超声波）取决于超声波换能器的数量。 超声波振子的数量取决于产生振动的地方是多还是少（也就是辐射面积大小），如果输出相对于该区域较低，则会导致清洁不均匀。 此外，由于液体的负荷，很难振动，因此需要适当选择输出。此外，Kelisonic超声波发生器可以调节输出大小，在这种调整中，超声波振子的（振幅）的宽度（振幅）增大或减小。于它也是决定空化密度的一个因素，因此通过调整超声波发生器的输出来设置适当的输出也很重要。

　　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.
