Ultrasonic cleaning related Technical Issues
Ultrasonic Frequency Physically, mechanical waves with a frequency greater than the frequency are called ultrasonic waves. The lower the ultrasonic frequency, the easier it is to create a cavity in the liquid. The force generated is greater and the effect is stronger. It is suitable for the initial ultrasonic cleaning of rough workpieces. The higher the frequency, the stronger the directionality of ultrasonic waves, which is suitable for precision cleaning of fine workpieces.
The sound power density of the emission power/emission area can usually meet the cleaning requirements. The power density of our commonly used ultrasonic waves is greater than that, which is fully sufficient for ordinary industrial cleaning. The higher the power density, the stronger the cavity effect, the faster the speed, and the better the cleaning effect. However, for precision products with very high surface finish, long-term high-power density cleaning will cause cavity corrosion on the product surface.
Cleaning media Ultrasonic cleaning generally includes two types of cleaning agents: chemical cleaning agents and water-based cleaning agents. The chemical action of the cleaning medium can accelerate the cleaning effect of ultrasonic waves. Ultrasonic cleaning is a physical action. The two actions are combined to clean the product. Clean thoroughly and thoroughly.
Cleaning temperature Generally speaking, the cavity effect of ultrasonic waves is best at ℃. If a cleaning agent is used, the higher the temperature, the more significant the effect will be. Usually, when applying ultrasonic cleaning in practice, it is better to use an operating temperature of ℃.
When cleaning, the placement of the product and the amount of cleaning fluid should be selected. Generally, the liquid level of the cleaning fluid should be higher than the vibration surface. For larger workpieces, stainless steel mesh cages are generally used for cleaning. The mesh of the mesh cage affects the cleaning effect. It has a certain impact. The current inspection requirements for industrial cleaning require that the mesh size should be larger than.
The sound that people hear is a sound wave signal with a frequency higher than that. Sound waves with a higher frequency are called ultrasonic waves. The transmission of sound waves propagates longitudinally according to a sinusoidal curve, that is, one layer is strong and the other is weak, and they are transmitted in sequence. When the weak sound wave signal When acting on the liquid, a certain negative pressure will be generated on the liquid, that is, the volume of the liquid will increase, and the molecular gaps in the liquid will increase, forming many tiny bubbles. When a strong sound wave signal acts on the liquid, it will cause a negative pressure on the liquid. A certain positive pressure is generated, that is, the volume of the liquid is compressed and reduced, and the tiny bubbles formed in the liquid are crushed. Research has proven that when ultrasonic waves act on a liquid, the collapse of each bubble in the liquid will produce a shock wave with extremely high energy, which is equivalent to an instantaneous high temperature of several hundred degrees and a pressure of up to thousands of atmospheres. This phenomenon is called cavitation. , Ultrasonic cleaning uses the shock waves generated by the bursting of bubbles in the liquid to clean and wash the internal and external surfaces of the workpiece. The second ultrasonic wave propagates in the liquid, causing the liquid and the cleaning tank to vibrate together at the ultrasonic frequency. When the liquid and the cleaning tank vibrate, they have their own natural frequencies. This vibration frequency is the frequency of sound waves, so people hear a buzzing sound.
What are ultrasonic waves? They can be divided into three types, namely infrasonic waves and ultrasonic waves. The frequency of infrasound waves is below the frequency of sound waves and the frequency of ultrasonic waves is above. The infrasound and ultrasonic waves are generally inaudible to human ears. Ultrasonic waves have high frequency and short wavelength, so they have good propagation direction and strong penetration ability. This is why ultrasonic cleaning machines are designed and manufactured.
How ultrasonic waves complete the cleaning work
Ultrasonic cleaning uses the socialization, acceleration, and direct flow of ultrasonic waves in the liquid to directly and indirectly affect the liquid and dirt, so that the dirt layer is dispersed, emulsified, and peeled off And achieve the purpose of cleaning. Among currently used ultrasonic cleaning machines, cavitation and direct flow are used more frequently.
Cavitation Cavitation is the transmission of ultrasonic waves into liquids in the form of interactive high-frequency transformations of compression and decompression more than 20,000 times per second. When the pressure is reduced, the phenomenon of vacuum core bubbles is generated in the liquid. When the compression force is applied, the vacuum core bubbles generate a strong impact force when they are crushed by the pressure, thereby peeling off the dirt on the surface of the object to be cleaned, thereby achieving precision. Cleansing purpose.
During the ultrasonic cleaning process, the bubbles visible to the naked eye are not vacuum core bubbles, but air bubbles, which inhibit cavitation and reduce cleaning efficiency. Only when the air bubbles in the liquid are completely removed can the vacuum core bubbles of cavitation achieve the best effect.
The phenomenon of direct flow in which ultrasonic waves generate flow in the liquid along the direction of sound propagation is called direct flow. When the sound wave intensity is high, the straight flow can be seen with the naked eye, and the flow is generated perpendicular to the vibration surface, and the flow speed is about /. Through this straight flow, the slightly oily dirt on the surface of the object to be cleaned is stirred, and the cleaning liquid on the surface of the dirt also generates convection. The dissolved liquid that dissolves the dirt is mixed with the new liquid, which speeds up the dissolution speed and plays an important role in the transportation of dirt. big effect.
Acceleration The acceleration caused by the push of liquid particles. For ultrasonic cleaning machines with higher frequencies, the cavitation effect is very insignificant. The cleaning at this time mainly relies on the acceleration of liquid particles under the action of ultrasound to impact particles to carry out ultra-precise cleaning of dirt.
The composition of ultrasonic cleaning machine Ultrasonic cleaning machine mainly consists of two parts: ultrasonic cleaning tank and ultrasonic generator. The ultrasonic cleaning tank is made of high-quality stainless steel with strong elasticity, good corrosion resistance, and an ultrasonic transducer vibrator installed at the bottom. The ultrasonic generator generates high frequency and high voltage, which is transmitted to the transducer through the cable connection line. The transducer and the vibration plate together generate high voltage. Frequency resonance causes the solvent in the cleaning tank to be affected by ultrasonic waves to clean dirt.
Advantages of ultrasonic cleaning machine equipment
Pervasive. Since the ultrasonic action occurs throughout the liquid, the surfaces of all objects that can come into contact with the liquid are cleaned, and it has a unique effect on objects with complex shapes and many gaps.
Autumn is intact. Traditional manual or chemical cleaning often causes mechanical wear or chemical corrosion, but ultrasonic cleaning does not cause any damage to the object.
Wash everything and make everything clean. In addition, when suitable cleaning agents are used for objects of different properties, the penetration and dissolution of the cleaning agent is enhanced by ultrasonic waves and fully exerted, so all objects will look brand new after cleaning.
Ultrasonic cleaning machines are used for cleaning in various industries, including the optical industry, the automotive industry, the hardware industry, the electronics industry, the laboratory, the printing industry, the electroplating industry, the precision parts industry, the glasses industry, the jewelry industry, the jade industry, the clock industry, the semiconductor industry, the communication equipment industry, the precious metal industry, the stainless steel industry, the electric power industry, etc. and other industries.
