The working principle of ultrasonic cleaning machine is mainly based on the cavitation effect generated by ultrasonic waves. The following is the specific working process:
超聲波發(fā)生器:產(chǎn)生高頻振蕩信號(hào)2。
Ultrasonic generator: generates high-frequency oscillation signal 2.
換能器:將高頻電信號(hào)轉(zhuǎn)換成機(jī)械振動(dòng)3。
Transducer: Convert high-frequency electrical signals into mechanical vibrations.
清洗液:超聲波通過換能器傳遞到清洗液中,使液體產(chǎn)生振動(dòng)。
Cleaning solution: Ultrasonic waves are transmitted to the cleaning solution through a transducer, causing the liquid to vibrate.
氣泡形成:在液體中形成數(shù)以萬計(jì)的微小氣泡(直徑約50-500μm)。
Bubble formation: tens of thousands of tiny bubbles (with a diameter of about 50-500 μ m) are formed in liquid.
Bubble vibration: These bubbles vibrate under the action of sound field and form and grow in the negative pressure zone, quickly closing in the positive pressure zone.
Cavitation effect: When bubbles close, shock waves are generated, resulting in pressures of up to 1012-1013pa and local high temperatures, which disrupt the adsorption of dirt and cleaning surfaces, causing fatigue damage to the dirt layer and leading to detachment.
Cleaning effect: By continuously generating instantaneous high pressure, a series of small "explosions" are simulated, constantly impacting the surface of the object, causing the dirt on the surface and gaps of the object to quickly peel off, achieving the purpose of cleaning and purification.
Ultrasonic cleaning machines are suitable for cleaning precision components and complex structures, effectively removing grease and dirt, and have little impact on the material and accuracy of the cleaned objects.
