Process application

The ultrasonic defoamer, also known as an ultrasonic deaerator, operates on the core principle of utilizing ultrasonic energy to eliminate bubbles in liquids. During operation, an ultrasonic generator produces high-frequency electrical signals, which are converted into mechanical vibrations (ultrasonic waves) of the same frequency by a transducer. These vibrations are transmitted through a medium (typically water or coupling fluid) to the container wall and then into the liquid being processed. As ultrasonic waves propagate through the liquid, they create alternating high-pressure and low-pressure cycles. During the low-pressure phase, micro-bubbles dissolved in the liquid rapidly nucleate and grow; in the subsequent high-pressure phase, these bubbles are violently compressed and implode (collapse), a process known as the "cavitation effect." The powerful shockwaves and localized high temperature and pressure generated by cavitation effectively break down existing large bubbles in the liquid into micro-bubbles, accelerating their dissolution or rise to the surface, thereby achieving rapid and efficient deaeration.
