The ultrasonic cleaning machine has three cleaning functions: ultrasonic energy function, acceleration function and DC function:

超聲的能量效應。

Energy effect of ultrasound.

超聲的能量非常大。其在介質液體中傳播時，向介質顆粒傳輸能量，再向介質表面傳輸能量，使污染物離解、擴散。聲是一種縱波，即介質粒子的振動方向和聲波傳播方向一致。在縱波傳播過程中，介質導致粒子分布不均，粒子在不同密度區域運動，在密度分布區域稀疏聲波形成負壓，致密分布區域聲波形成聲壓，并形成負、正壓力連續變化，這種變化不僅使介質獲得了顆粒的動能，并獲得一定的加速度。高頻率超聲的能量影響很大。在與塵埃粒子相互作用時，能量向塵埃傳輸能量，使塵埃粒子分解、分散。

The energy of ultrasound is very large. When it propagates in the medium liquid, it transmits energy to the medium particles, and then transmits energy to the medium surface to dissociate and diffuse the pollutants. Sound is a longitudinal wave, that is, the vibration direction of medium particles is consistent with the propagation direction of sound wave. In the process of P-wave propagation, the medium causes uneven distribution of particles, and the particles move in different density areas. In the density distribution area, the sparse sound wave forms a negative pressure, and in the dense distribution area, the sound wave forms a sound pressure, and forms a continuous change of negative and positive pressure. This change not only enables the medium to obtain the kinetic energy of particles, but also a certain acceleration. High frequency ultrasound has a great influence on the energy. When interacting with dust particles, energy transmits energy to dust, which decomposes and disperses dust particles.

加速：由液體微粒推動的加速。對高頻超聲波清洗機而言，空穴效應非常小，則主要依靠液相微粒在超聲波沖擊粒子的加速作用下對污垢進行超精密清洗。

Acceleration: acceleration driven by liquid particles. For high-frequency ultrasonic cleaning machine, the hole effect is very small, so it mainly depends on the ultra precision cleaning of dirt by liquid particles under the acceleration of ultrasonic impact particles.

直流效應：超聲波清洗機在液體中沿聲波方向流動的現象叫做直流。聲波場在0.5W/cm2范圍內，通過肉眼觀察到與振動面垂直的直入流，速度約為10cm/s。攪動被清潔物體表面的微油污垢，并使污垢表面的清潔液產生對流。在溶解污物中溶解的溶液與新液體混合，加速溶解速度，對污物的處理有重要作用。

Direct current effect: the phenomenon of ultrasonic cleaning machine flowing along the direction of sound wave in liquid is called direct current. When the acoustic field is in the range of 0.5w/cm2, the direct inflow perpendicular to the vibration surface is observed by naked eyes, and the velocity is about 10cm / s. Stir the micro oil dirt on the surface of the cleaned object and make the cleaning liquid on the dirt surface convection. The solution dissolved in the dissolved dirt is mixed with the new liquid to accelerate the dissolution rate, which plays an important role in the treatment of dirt.
