How to choose ultrasonic cleaning machine?
1、 When you buy an ultrasonic cleaning machine, you must know which way to clean your products, because different ultrasonic cleaning machines have different effects;
2、 Need to know your cleaning products, it needs to achieve what kind of cleanliness, according to the different cleanliness, you can choose different types.
3、 It is necessary to know the cleaning output of the product, because the efficiency of the ultrasonic cleaning machine should be matched.
Also important is quality and service. Price is important, but quality is more important
Power selection
Ultrasonic cleaning sometimes uses low power and takes a long time without removing dirt. If the power reaches a certain value, the dirt will be removed quickly. If the power is too high, the cavitation strength will be greatly increased, and the cleaning effect will be improved. But at this time, the more precise parts also produce corrosion spots. Moreover, the vibration plate at the bottom of the cleaning machine has serious cavitation, and the water point corrosion is also increased When using trichloroethylene and other organic solvents, there is basically no problem, but when using water or water-soluble cleaning fluid, it is easy to suffer from water spot corrosion. If the surface of vibrating plate has been damaged, cavitation corrosion at the bottom of water under strong power is more serious. Therefore, ultrasonic power should be selected according to the actual use.
Frequency selection
The frequency of ultrasonic cleaning ranges from 28kHz to 120kHz. When water or water cleaning agent is used, the physical cleaning force caused by cavitation is obviously beneficial to the low frequency. Generally, it is about 28-40khz. For parts with small clearance, slit and deep hole, it is better to use high frequency (generally more than 40KHz) or even several hundred kHz. When cleaning the clock parts, use 100kHz. If using broadband FM cleaning, the effect is better.
