Pretreatment before the ultrasonic cleaner starts to operate

Before cleaning, it is advisable to use a bamboo knife to clean the dirt on the surface of the parts (for example, there will be a lot of dust on the outer surface of the dust cover, and the parts of the cylinder block will accumulate a lot of thick and easy-to-remove sludge where the curve of the outer casing changes). in order to extend the life of the cleaning fluid.

Ultrasonic can carry out precise cleaning, but its ability to treat mud-like dirt is weak, so in pretreatment, yellow mud or thin mud-like dirt should be removed as much as possible.

How does the ultrasonic cleaner make the correct choice of cleaning power

The effect of ultrasonic cleaning is not necessarily proportional to (power × cleaning time), sometimes with low power, it takes a long time to remove the dirt. And if the power reaches a certain value, the dirt is sometimes quickly removed. If the selected power is too large, the cavitation strength will be greatly increased, and the cleaning effect will be improved, but at this time, the more precise parts will also be corroded, which is not worth the loss, and the cavitation at the vibration plate at the bottom of the cleaning tank will be serious, and the water point corrosion will also increase. When using organic solvents such as trichloroethylene, there is basically no problem, but when using water or water-soluble cleaning liquid, it is easy to be corroded by water pits. Seriously, so the ultrasonic power should be selected according to the actual usage.
