1. Understanding ultrasound

用超聲波可以分為三種，即次聲波、聲波、超聲波。次聲波的頻率為20Hz以下；聲波的頻率為20Hz~20kHz；超聲波的頻率則為20kHz以上。其中的次聲波和超聲波一般人耳是聽不到的。超聲波由于頻率高、波長短，因而傳播的方向性好、穿透能力強(qiáng)，這也就是為什么設(shè)計制作全自動超聲波清洗機(jī)機(jī)的原因。

Ultrasonic can be divided into three types: infrasound wave, sound wave and ultrasonic wave. The frequency of infrasound wave is below 20Hz; The frequency of sound wave is 20Hz ~ 20kHz; The frequency of ultrasonic wave is more than 20kHz. The infrasound wave and ultrasonic wave can not be heard by ordinary human ears. Due to high frequency and short wavelength, ultrasonic has good directionality and strong penetration ability, which is why the full-automatic ultrasonic cleaning machine is designed and manufactured.

2、超聲波如何完成清洗工作

2. How does ultrasonic cleaning work

全自動超聲波清洗機(jī)是利用超聲波在液體中的社會化作用、加速度作用及直進(jìn)流作用對液體和污物直接、間接的作用，使污物層被分散、乳化、剝離而達(dá)到清洗目的。目前所用的全自動超聲波清洗機(jī)機(jī)中，空化作用和直進(jìn)流作用應(yīng)用得更多。

The full-automatic ultrasonic cleaning machine uses the socialization, acceleration and direct inflow of ultrasonic in the liquid to directly and indirectly affect the liquid and dirt, so that the dirt layer is dispersed, emulsified and stripped to achieve the purpose of cleaning. At present, in the full-automatic ultrasonic cleaning machine, cavitation and direct flow are more applied.

（1）空化作用：空化作用就是超聲波以每秒兩萬次以上的壓縮力和減壓力交互性的高頻變換方式向液體進(jìn)行透射。在減壓力作用時，液體中產(chǎn)生真空核群泡的現(xiàn)象，在壓縮力作用時，真空核群泡受壓力壓碎時產(chǎn)生強(qiáng)大的沖擊力，由此剝離被清洗物表面的污垢，從而達(dá)到精密洗凈目的。

(1) Cavitation: cavitation is the transmission of ultrasonic wave to liquid in the form of high-frequency transformation of compression force and pressure reduction interaction more than 20000 times per second. When the pressure is reduced, the phenomenon of vacuum nuclear bubbles is generated in the liquid. When the compression force is applied, the vacuum nuclear bubbles are crushed by pressure to produce a strong impact force, so as to peel off the dirt on the surface of the cleaned object, so as to achieve the purpose of precision cleaning.

（2）直進(jìn)流作用：超聲波在液體中沿聲的傳播方向產(chǎn)生流動的現(xiàn)象稱為直進(jìn)流。聲波強(qiáng)度在0.5W/cm2時，肉眼能看到直進(jìn)流，垂直于振動面產(chǎn)生流動，流速約為10cm/s。通過此直進(jìn)流使被清洗物表面的微油污垢被攪拌，污垢表面的清洗液也產(chǎn)生對流，溶解污物的溶解液與新液混合，使溶解速度加快，對污物的搬運(yùn)起著很大的作用。

(2) Direct inflow: the phenomenon that ultrasonic wave flows along the propagation direction of sound in liquid is called direct inflow. When the sound wave intensity is 0.5w/cm2, the naked eye can see the direct inlet flow, which is perpendicular to the vibration surface, and the flow velocity is about 10cm / s. Through this direct inflow, the micro oil dirt on the surface of the cleaned object is stirred, and the cleaning solution on the dirt surface also generates convection. The dissolved solution of the dissolved dirt is mixed with the new solution to accelerate the dissolution speed, which plays a great role in the handling of the dirt.

（3）加速度：液體粒子推動產(chǎn)生的加速度。對于頻率較高的全自動超聲波清洗機(jī)機(jī)，空化作用就很不顯著了，這時的清洗主要靠液體粒子超聲作用下的加速度撞擊粒子對污物進(jìn)行超精密清洗。

(3) Acceleration: the acceleration caused by the pushing of liquid particles. For the full-automatic ultrasonic cleaning machine with high frequency, the cavitation effect is not significant. At this time, the cleaning mainly depends on the acceleration of liquid particles under the ultrasonic action to impact the particles for ultra precision cleaning.

3、全自動超聲波清洗機(jī)機(jī)的原理是什么

3. What is the principle of automatic ultrasonic cleaning machine

超聲波換能器將高頻振蕩電訊號轉(zhuǎn)換成高頻機(jī)械振蕩，以縱波的形式在清洗液中輻射。在輻射波擴(kuò)張的半波期間，清洗液的致密性破壞并形成無數(shù)直徑為50-500μm的氣泡。這種氣泡中充滿著溶液蒸汽。在壓縮的半波期間，氣泡訊速閉合，會產(chǎn)生上百M(fèi)pa的局部液壓撞擊。這種現(xiàn)象稱為“空化”效應(yīng)。在“空化”效應(yīng)的連續(xù)作用下，工件表面或隱蔽處的污垢被爆裂、剝落。同時，在超聲的作用下，清洗液的滲透作用加強(qiáng)；脈動攪拌加?。蝗芙?、分散和乳化加速；從而將工件徹底清洗干凈。

The ultrasonic transducer converts the high-frequency oscillation electrical signal into high-frequency mechanical oscillation and radiates in the cleaning solution in the form of longitudinal wave. During the half wave of radiation wave expansion, the compactness of the cleaning fluid is destroyed and numerous particles with a diameter of 50-500 are formed μ M bubbles. This bubble is filled with solution vapor. During the half wave of compression, the bubble velocity closes, resulting in a local hydraulic impact of hundreds of MPa. This phenomenon is called "cavitation" effect. Under the continuous action of "cavitation" effect, the dirt on the workpiece surface or hidden place is burst and peeled off. At the same time, the penetration of cleaning fluid is strengthened under the action of ultrasound; Pulsating stirring intensifies; Accelerated dissolution, dispersion and emulsification; So as to thoroughly clean the workpiece.

The tank of the full-automatic ultrasonic cleaning machine is made of strong, elastic and corrosion-resistant high-quality stainless steel, and the bottom is equipped with an ultrasonic transducer vibrator; The ultrasonic generator generates high frequency and high voltage, which is transmitted to the transducer through the cable connecting line.
