4 points to note when buying an ultrasonic cleaner

作者: Release Date: 2019-07-02 Author: Click:

First, the choice of power: sometimes the ultrasonic cleaner uses low power, takes a long time and does not remove dirt. If the power reaches a certain value, the dirt will be removed quickly. If the power is too large, the cavitation intensity will be greatly increased and the cleaning effect will be improved. At this time, more accurate parts will also have etch points, the vibration plate at the bottom of the washing machine will be severely cavitation, and water spot corrosion will increase. When an organic solvent such as trichloroethylene is used, there is basically no problem. When using water or water-soluble cleaning solutions, it is susceptible to pitting corrosion. If the surface of the vibration plate is scratched, cavitation corrosion is more serious at high power. Select ultrasonic power for practical use.


Second, the choice of frequency:


The frequency of the ultrasonic cleaner is 28 kHz to 120 kHz. The physical cleaning power caused by cavitation when using water or water-cleaning agents obviously favors low frequencies. Generally, 28-40kHz is used. on. For parts with small gaps, slits and deep holes, it is best to use high frequencies (typically higher than 40 kHz), even hundreds of kHz. When cleaning watch parts, use 100kHz. If you use broadband FM cleaning, the effect will be better.

Third, the use of cleaning baskets:


Baskets are often used when cleaning small parts. When the frequency is 28khz, it is better to use a grid of 10mm or larger.


Fourth, the temperature of the cleaning solution:


The most suitable cleaning temperature of the water cleaning solution is 40-6. 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 a heating cylinder to heat a heating wire for temperature control. When the temperature rises, cavitation easily occurs, so the cleaning effect is good. When the temperature continues to rise, the pressure of the gas in the cavitation increases, causing the impact sound pressure to decrease and the effect to weaken. The organic solvent cleaning solution is washed at a temperature near the boiling point. 5. Determine the amount of cleaning fluid and the location of the cleaning components:


Generally the cleaning level is better than 100mm above the vibrator surface. Because the single-frequency cleaning machine is affected by the standing wave field, the node's amplitude is small, and the amplitude at the amplitude is large, resulting in uneven cleaning. Therefore, the best choice for cleaning items should be placed on volatility. (More effective range 3-18 cm)
