You can purchase according to your own requirements:
1. Frequency selection.
The frequency of ultrasonic cleaning is in the frequency range of 28kHz~120kHz, and the physical cleaning force caused by cavitation is obviously beneficial to the low frequency when using water or water cleaning agent, and it is generally used around 28-40khz. For small clearance, slit, deep hole parts cleaning, high frequency (more than 40kHz) better, or even a few hundred kHz.
2. Power selection.
Ultrasonic cleaning sometimes takes a long time and does not remove dirt. If the power reaches a certain value, the dirt will be removed quickly. If choose power is too large, the cavitation intensity will greatly increase, cleaning effect is improved, but the precision parts are produced points, and at the bottom of the washing machine vibration plate cavitation is serious, water point corrosion also increased.
3. Temperature of cleaning liquid.
More suitable for cleaning water cleaning fluids temperature of 40-60 ℃, especially if at the time of the day is cold cleaning fluid temperature low effect is poor, cleaning effect is poor. Therefore, a part of the cleaning machine is used to heat the heating wire outside the washing cylinder to control the temperature. When the temperature is raised, the air is easy to occur, so the cleaning effect is better.
4. Use of cleaning basket.
When cleaning small parts, often use nets, because the mesh should cause ultrasonic attenuation, special attention should be paid. When the frequency is 28khz, it is good to use mesh with more than 10mm.
5. The amount of cleaning fluid and the location of cleaning parts are determined.
The general cleaning liquid level is higher than 100mm above the vibration subsurface. Due to the influence of the standing wave field, the amplitude of the wave section is very small, and the amplitude of the wave amplitude is large and the cleaning is not uniform. Therefore, the better selection of cleaning items should be placed in the waveform. (effective range 3-18 cm)
6. Ultrasonic cleaning process and cleaning fluid selection.
Before buying cleaning system, should be cleaning to do the following analysis: clear wash a number of material composition, structure, and analysis and clearly to remove the dirt, these are all decided to use what kind of cleaning method, the application of water-based cleaning fluid or solvent prerequisite. After the cleaning process, the cleaning experiment should be done to verify. Only in this way can the proper cleaning system be provided, the reasonable cleaning procedure and cleaning fluid are designed.
I believe that you have a good understanding of how to select the ultrasonic cleaning machine. I hope I can help you, if you still have any questions, please feel free to contact us.
