Precautions for selecting an ultrasonic cleaner

Ultrasonic cleaning machine brings active and convenient production and life, and its clear effect is good. Many people do not know how to choose when purchasing ultrasonic cleaning machine. What problems should be paid attention to when choosing? The following is a brief introduction to the ultrasonic cleaning machine, and several points to be noted in the selection of ultrasonic:

1 , the selected power and frequency should be suitable

     The ultrasonic cleaning effect is not necessarily proportional to (power × cleaning time), sometimes with low power, and it takes a long time to remove dirt. And if the power reaches a certain value, the dirt is sometimes removed quickly. If the power is too large, the cavitation intensity will be greatly increased, and the cleaning effect will be improved. However, the more precise parts will also have an etch point, which is not worth the loss, and the cavitation at the bottom of the cleaning cylinder is severe, and the water point corrosion is also increased. Big.
Ultrasonic cleaning frequency is from 28 kHz to 120 kHz . The physical cleaning force caused by cavitation when using water or water cleaning agent is obviously beneficial to low frequencies, generally around 28-40 kHz . For parts with small gaps, slits and deep holes, it is better to use high frequency (generally 40 kHz or more), even several hundred kHz . When cleaning the watch parts, use 400kHz . If you use broadband FM cleaning, the effect is better.

2 , the correct choice of cleaning solution cleaning temperature

     The most suitable cleaning temperature for water cleaning solution is 40 -60 ° C Especially in the case of cold weather, if the temperature of the cleaning solution is low and the cavitation effect is poor, the cleaning effect is also poor. Therefore, some washing machines are wound around the heating cylinder to heat the heating wire for temperature control. When the temperature rises, cavitation is easy to occur, so the cleaning effect is good. When the temperature continues to rise, the gas pressure in the cavitation increases, causing the impact sound pressure to drop.

3 , the amount of cleaning fluid and cleaning parts position determination

     Generally, the level of the cleaning liquid is higher than the surface of the vibrator 100mm The above is better. Since the single-frequency cleaning machine is affected by the standing wave field, the amplitude at the node is small, and the amplitude at the amplitude is large, resulting in uneven cleaning. Therefore, the best choice for cleaning items should be placed at the volatility.

4 , cleaning methods and determination of the type of cleaning fluid

     Before purchasing the cleaning system, the following application analysis should be carried out on the parts to be cleaned: the material composition, structure and quantity of the parts to be washed are clearly defined, and the dirt to be removed is analyzed and determined. These are all deciding which cleaning methods to use and judging the application. Aqueous cleaning solutions are also a prerequisite for solvents. The final cleaning process also requires a cleaning experiment to verify. Only in this way can a proper cleaning system, a well-designed cleaning process and a cleaning solution be provided.

5 , when cleaning liquid is selected, what points to pay attention to

    The cleaning effect of the ultrasonic cleaning machine plays a vital role in cleaning the liquid. When selecting the cleaning liquid, the following factors should be noted:

( 1 ) Cleaning efficiency: When selecting the most effective cleaning solvent, it is necessary to do the experiment. If ultrasound is introduced into an existing cleaning process, the solvent used generally does not have to be changed;
( 2 ) Simple operation: the liquid used should be safe and non-toxic, easy to operate and long in service life;
( 3 ) Cost: The cost of using the cheapest cleaning solvent is not necessarily the lowest. The cleaning efficiency and safety of the solvent, the amount of solvent that can be cleaned, and the highest utilization rate of the workpiece must be taken into consideration.

In order to make good use of the ultrasonic cleaning machine, it is necessary to pay attention to the above five points. Especially for the selection of the cleaning solution, special attention must be paid to the cleaning effect of the cleaning machine. When selecting, it must be carried out according to strict procedures. .
