Ultrasonic cleaners are a highly efficient cleaning device, but there are some common problems that may be encountered in daily use. The following is a guide to daily problems with ultrasonic cleaners:
What is cavitation?Cavitation refers to the phenomenon of millions of tiny bubbles that form rapidly and burst in a liquid, caused by the interaction of high and low pressure waves formed by high-frequency ultrasound. In the low-pressure phase, the bubbles gradually become larger and are compressed and implosed during the high-pressure phase.
How to achieve the best cleaning results?Choosing the right cleaning fluid is crucial, while maintaining the correct cleaning temperature and time. Choosing the right size and type of ultrasonic cleaner is also key.
Will ultrasonic cleaning damage the workpiece?Most workpieces are safe for ultrasonic cleaning. Pay attention to the choice of cleaning fluid, some workpieces may react differently to the cleaning fluid. It is not recommended for certain gemstones such as opal, pearls, etc.
What is the difference between direct and indirect cleaning?Direct cleaning means that the workpiece is placed directly into the cleaning tank, while indirect cleaning is when the workpiece is placed in a beaker or tray and cleaned indirectly by solution. Note that direct cleaning requires the selection of a cleaning solution that does not damage the cleaning tank.
Why do I need a special cleaning solution?The purpose of the cleaning solution is to break the connection between the dirt and the workpiece, and ultrasonic cavitation assists the cleaning solution to clean it. The cleaning solution contains a variety of components, such as wetting agents and surfactants, to improve the cleaning effect.
How to choose a cleaning solution?Commonly used ultrasonic cleaning fluids are compounds that mix cleaning ingredients, wetting agents, and other reactive components. Choosing the right cleaning fluid is essential for effective cleaning of the workpiece.
What cleaning fluids should not be used?Avoid using flammable or low-flashpoint solutions, as well as acidic cleaning fluids and bleach, as they may damage equipment or create hazards.
When should I replace the cleaning fluid?Replace the cleaning fluid when it is significantly reduced, dirty, or failing.
Why keep the liquid level?Maintaining the correct liquid level is to maintain the "tuning" of the ultrasonic cleaning system, ensuring that the cleaning environment is not affected to improve cleaning efficiency and protect the equipment.
What is the length of the cleaning time?The cleaning time depends on factors such as soil, cleaning fluid, temperature and cleanliness requirements. The cleaning time needs to be adjusted according to the actual application.
What is the function of the heating device?The heating unit is mainly used to maintain the temperature of the cleaning solution during the cleaning process, as cavitation generates heat.
What is the optimal cleaning temperature?Heating usually increases the speed of cleaning, while the chemistry of most cleaning fluids is at a certain temperature to achieve the best cleaning results, usually between 50 and 65.
The above problem solving guide provides some suggestions and solutions in the daily use of ultrasonic cleaners.
