How the ultrasonic bottle washer completes the cleaning work

Ultrasonic cleaning items have obvious advantages, so how does ultrasonic complete the cleaning work? Ultrasonic cleaning is the use of ultrasonic cavitation, acceleration and direct flow in the liquid direct and indirect action on the liquid and dirt, so that the dirt layer is dispersed, emulsified, peeled off to achieve the purpose of
cleaning.

In the ultrasonic cleaning machines currently in use, cavitation and direct flow are more used
.

(1) Cavitation: cavitation is the transmission of ultrasonic waves to the liquid in the form of high-frequency transformation of compression force and pressure reduction interaction of more than 20,000 times per second
.

In the pressure reduction effect, the phenomenon of vacuum nuclear group bubbles is generated in the liquid, and when the compressive force is applied, the vacuum nuclear group bubbles produce a strong impact force when crushed by pressure, thereby stripping the dirt on the surface of the cleaned object, so as to achieve the purpose of
precision cleaning.

In the ultrasonic cleaning process, the bubbles visible to the naked eye are not vacuum nuclear group bubbles, but air bubbles, which have an inhibitory effect on cavitation and reduce cleaning efficiency
.

Only when the air bubbles in the liquid are completely removed, the cavitation of the vacuum nuclear bubbles can achieve the desired effect
.

(2) Direct inlet flow: The phenomenon of ultrasonic waves flowing in the direction of sound propagation in a liquid is called direct inflow
.

When the sound intensity is 0.
5W/cm2, the naked eye can see the direct inflow and generate a flow perpendicular to the vibration plane, and the flow rate is about 10cm/s
.

Through this direct inlet flow, the slightly oily dirt on the surface of the cleaned object is stirred, and the cleaning liquid on the surface of the dirt also produces convection, and the dissolved liquid of the dissolved dirt is mixed with the new liquid, which accelerates the dissolution speed and plays a great role
in the handling of the dirt.

(3) Acceleration: The acceleration generated by the push of liquid particles
.

For ultrasonic cleaning machines with higher frequencies, cavitation is very insignificant, and the cleaning at this time mainly relies on the acceleration of liquid particles under the ultrasonic action of liquid particles to carry out ultra-precision cleaning
of dirt.
