1, with ultrasonic can be divided into three kinds, that is, the second wave, sound wave, ultrasonic wave. The frequency of the second sound wave is below 20Hz and the frequency of the sound wave is 20Hz~20kHz;

Ultrasonic frequency is above 20kHz. In which the second sound wave and ultrasonic wave is generally not heard. Due to the high frequency and short wavelength, the ultrasonic wave

The direction of the spread of good, strong penetration, which is why the design of the production of ultrasonic cleaning machine.

2, ultrasonic how to complete the cleaning work

Ultrasonic cleaning is the use of ultrasonic wave in the liquid of the social role, the role of acceleration and direct flow of liquid and dirt directly,

The indirect effect of the dirt layer is dispersed, emulsified and stripped to achieve the purpose of cleaning. Currently used in the ultrasonic cleaning machine, empty into

With and straight into the flow of the role of more.

(1) cavitation: the effect of cavitation is the high frequency conversion of twenty thousand times per second, the compression force and the reduction of pressure

Transmission of the liquid to the liquid. In the reduction of pressure, the liquid in the generation of the phenomenon of vacuum nuclear group, in the role of compression force, the vacuum

When the nucleus is crushed by the pressure, it has a strong impact force, which is stripped from the dirt on the surface of the cleaning material, so as to achieve the purpose of precision cleaning.

(2) straight into the flow of the effect: ultrasonic wave in the liquid along the direction of the sound generated by the flow of the phenomenon known as the straight flow. Acoustic intensity

0.5W/cm2, the naked eye can see straight into the flow, perpendicular to the vibration surface flow, the flow rate of about 10cm/s. through this straight into the flow so that the

The micro oil dirt on the surface of the washing is stirred, and the cleaning liquid on the dirt surface also generates convection, and the solution of the dissolved contaminant is mixed with the new liquid,

Speed up the dissolution rate, the removal of dirt plays a great role.

(3) acceleration: the acceleration produced by a liquid particle. For the higher frequency ultrasonic cleaning machine, the role of cavitation is not

Significantly, then the cleaning mainly by the liquid particles under the effect of the acceleration of the particle impact on the dirt for ultra precision cleaning.

3, what is the principle of ultrasonic cleaning machine

The high frequency oscillation signal is converted into high frequency mechanical oscillation by ultrasonic transducer, and the radiation from the cleaning liquid is in the form of longitudinal wave. In radiation

During the wave expansion of the half wave, the density of the cleaning fluid destroyed and formed numerous diameters of 50-500 m. This bubble is filled with

Solution vapor. During the compression of the half wave period, the bubble velocity is closed, and the local hydraulic impact of hundreds of Mpa is generated. This phenomenon is called "cavitation""

Effect。 Under the influence of the "cavitation" effect, the dirt on the surface of the work piece or the hidden place is burst and peeled off. At the same time, under the effect of ultrasound,

The osmotic effect of the cleaning liquid is enhanced; the pulsating agitation is intensified; the dissolution, dispersion and emulsification are accelerated; thereby, the workpiece is thoroughly cleaned.

4, ultrasonic cleaning machine is made up of which parts

The ultrasonic cleaning machine is mainly composed of two parts, ultrasonic cleaning tank and ultrasonic generator. Ultrasonic cleaning tank with strong flexibility, corrosion resistance

The bottom is provided with an ultrasonic transducer vibrator, and the ultrasonic generator generates high frequency and high voltage.

A high frequency resonance is generated between the transducer and the vibration plate, so that the solvent in the cleaning tank can be cleaned by the ultrasonic action.

5, ultrasonic cleaning machine, what are the characteristics

Ultrasonic cleaning and chemical, physical, chemical and physical and chemical cleaning methods, with the following unique advantages:

. Can quickly and thoroughly remove all kinds of dirt on the surface of the workpiece.

. Can clean with cavities, grooves and other forms of complex precision parts.

. Nondestructive to the surface of the workpiece.

. Can use a variety of cleaning agents.

. At room temperature or properly heated (about 60 C) can be cleaned.

. Integrated structure of the whole machine is easy to move.

. Saving solvents, cleaning paper, energy, work space and labor, etc..
