Ultrasonic cleaning - operation and applications of ultrasonic cleaning technology
Effective, gentle and environmentally friendly - mit of ultrasonic cleaning can be achieved highest purity grade. The dirty parts come in a cleaning bath, which will be offset by ultrasonic vibration. This is the cleaning principle Cavitation :
Cavitation is the formation and dissolution of cavities in liquids by pressure fluctuations. The cleaning fluid is excited by push and pull the fabric secondary longitudinal waves (pressure wave in the longitudinal direction) to the cavitation.
Distinction 2 borderline cases, gas cavitation and cavitation of the steam.
Gas cavitation: Often large amounts of gas, E.g. air in liquids are either resolved or in suspension. These gases increase in the pull phase of the ultrasound, coagulate (to bale together) in the printing phase and escape then (degassing).
Steam cavitation: When this desired cavitation, the voids (bubbles) contain mainly steam of the surrounding fluid. In the printing phase, these bubbles implode and generate locally high pressures and temperatures (ultrasonic cleaning). A steam cavitation can occur only in degassed or purified fluids.

Strong pulling the liquid column, microscopically tiny steam bubbles (cavitation bubble) are torn open. |

Implosion of vapour bubbles through redemption of the traction and transition in the compression. The steam bubble kavidiert. |

The released energy when the implosion is very high. Dirt particles are blown off virtually from the cleaning material. This Prtikel into the cleaning liquid and can through a targeted bath care (separator, filtration) the medium be removed. |
