What Problems May Be Encountered When Using Ultrasonic Cleaning Machine?
Jan 17, 2022
Common problems of ultrasonic cleaner are as follows:
1. What is cavitation?
Cavitation is the rapid formation and bursting of millions of tiny bubbles (or holes) in a liquid. Cavitation occurs as a result of the interaction of high and low pressure waves generated by high frequency sound waves (ultrasounds). At low pressure, the bubble gets bigger and bigger, while at high pressure, it compresses and implodes.
2, how can I achieve the best ultrasonic cleaning effect?
There are many conditions that can determine the final cleaning effect, of which the most important is to choose the right cleaning fluid, cleaning at the right temperature at the right time, choose the right size and type of ultrasonic cleaning machine.
3, with ultrasonic cleaning will damage my workpiece?
Ultrasonic cleaning is safe for most workpieces. The energy generated by the implosion of thousands of bubbles per second is enormous, but because the energy is concentrated in an extremely small area, the entire cleaning process is safe. The most careful consideration for safety should be the choice of cleaning solution. The potential damage of cleaning fluids to some workpiece surfaces may be increased by the use of ultrasound. Ultrasonic cleaning is not recommended for the following gems: opal, pearl, emerald, tanzanite zoisite, malachite, emerald, lapis lazuli and coral.
4, what is "direct" and "indirect" cleaning?
Direct cleaning usually means that the workpiece is cleaned in a cleaning tank filled with cleaning fluid, and the workpiece is usually placed in a tray or basket with holes. A limitation of direct cleaning is the need to select cleaning fluids that do not damage the ultrasonic cleaning tank. Indirect cleaning is to place the workpiece to be cleaned in a beaker or tray without holes, and the beaker or tray is filled with solution, rather than directly in the cleaning tank. When choosing indirect cleaning, make sure the water level in the tank is maintained at the standard position.
