1、了解超声波
1. Understanding ultrasound
用超声波可以分为三种,即次声波、声波、超声波。次声波的频率为20Hz以下;声波的频率为20Hz~20kHz;超声波的频率则为20kHz以上。其中的次声波和超声波一般人耳是听不到的。超声波由于频率高、波长短,因而传播的方向性好、穿透能力强,这也就是为什么设计制作亚洲城ca88手机版机的原因。
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、超声波如何完成清洗工作
2. How does ultrasonic cleaning work
亚洲城ca88手机版是利用超声波在液体中的社会化作用、加速度作用及直进流作用对液体和污物直接、间接的作用,使污物层被分散、乳化、剥离而达到清洗目的。目前所用的亚洲城ca88手机版机中,空化作用和直进流作用应用得更多。
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:空化作用就是超声波以每秒两万次以上的压缩力和减压力交互性的高频变换方式向液体进行透射。在减压力作用时,液体中产生真空核群泡的现象,在压缩力作用时,真空核群泡受压力压碎时产生强大的冲击力,由此剥离被清洗物表面的污垢,从而达到精密洗净目的。
(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)直进流作用:超声波在液体中沿声的传播方向产生流动的现象称为直进流。声波强度在0.5W/cm2时,肉眼能看到直进流,垂直于振动面产生流动,流速约为10cm/s。通过此直进流使被清洗物表面的微油污垢被搅拌,污垢表面的清洗液也产生对流,溶解污物的溶解液与新液混合,使溶解速度加快,对污物的搬运起着很大的作用。
(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:液体粒子推动产生的加速度。对于频率较高的亚洲城ca88手机版机,空化作用就很不显著了,这时的清洗主要靠液体粒子超声作用下的加速度撞击粒子对污物进行超精密清洗。
(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、亚洲城ca88手机版机的原理是什么
3. What is the principle of automatic ultrasonic cleaning machine
超声波换能器将高频振荡电讯号转换成高频机械振荡,以纵波的形式在清洗液中辐射。在辐射波扩张的半波期间,清洗液的致密性破坏并形成无数直径为50-500μm的气泡。这种气泡中充满着溶液蒸汽。在压缩的半波期间,气泡讯速闭合,会产生上百Mpa的局部液压撞击。这种现象称为“空化”效应。在“空化”效应的连续作用下,工件表面或隐蔽处的污垢被爆裂、剥落。同时,在超声的作用下,清洗液的渗透作用加强;脉动搅拌加剧;溶解、分散和乳化加速;从而将工件彻底清洗干净。
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.
4、亚洲城ca88手机版机是由哪几部分构成的
4. Which parts does the automatic ultrasonic cleaning machine consist of
超波清洗机主要由亚洲城ca88手机版槽和超声波发生器两部分构成。亚洲城ca88手机版槽用坚固弹性好、耐腐蚀的优质不锈钢制成,底部安装有超声波换能器振子;超声波发生器产生高频高压,通过电缆联结线传导给换能器,换能器与振动板一起产生高频共振,从而使清洗槽中的溶剂受超声波作用对污垢进行洗净。
The ultra wave cleaning machine is mainly composed of a full-automatic ultrasonic cleaning machine tank and an ultrasonic generator. 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. The transducer and the vibrating plate generate high frequency resonance together, so that the solvent in the cleaning tank can be cleaned by ultrasonic.
