working principle:
超声波清洗器是利用超声波在液体中的“空化效应”达到清洗和脱气目的。
Ultrasonic cleaner uses the "cavitation effect" of ultrasonic in liquid to achieve the purpose of cleaning and degassing.
超声波清洗器发出高频震荡信号,通过换能器转换成高频机械震荡,使之在清洗液中散播,使液体流动而产生数以万计的微小气泡,这些气泡在超声波传播过程中所形成的负压区成型、生长,在正压区迅速闭合。这些非稳态的微小气泡在声场的作用下每秒完成数万次压缩、扩张的物理过程,可产生超过1000个大气压的瞬间高压,就像一连串爆炸,不断冲击物体表面及缝隙中,从而达到全面清洗的效果。超声波在液体中还能起到加速溶解和乳化作用,达到脱气目的。
The ultrasonic cleaner sends out high-frequency vibration signal, which is converted into high-frequency mechanical vibration through the transducer, so that it can be spread in the cleaning solution, making the liquid flow and generating tens of thousands of tiny bubbles. These bubbles form and grow in the negative pressure area formed during the ultrasonic transmission process, and quickly close in the positive pressure area. These non-stationary tiny bubbles complete tens of thousands of physical processes of compression and expansion every second under the action of the sound field, which can produce instantaneous high pressure of more than 1000 atmospheres, just like a series of explosions, which constantly impact the surface of objects and gaps, thus achieving the effect of comprehensive cleaning. Ultrasound can also accelerate dissolution and emulsification in liquid to achieve degassing.
主要特点:
Main features:
1.超声波清洗是目前清洗效率高的清洗方式,对于手工及其它清洗方式不能完全更好地进行清洗的,如形状和结构复杂的工件等,具有显著的清洗效果,可达到清洗要求,且清洗均匀度一致;
1. Ultrasonic cleaning is a cleaning method with high cleaning efficiency at present. It has a significant cleaning effect for workpieces with complex shape and structure that cannot be cleaned completely and better by manual and other cleaning methods, and can meet the cleaning requirements, and the cleaning uniformity is consistent;
2.不需人手接触清洗液,安全可靠,减少了对工件表面的损伤,配合清洗剂的使用,可加速污染物的分离和溶解;
2. It is safe and reliable without touching the cleaning solution by human hands, which reduces the damage to the workpiece surface. With the use of cleaning agent, it can accelerate the separation and dissolution of pollutants;
3.能非常更好地排除液体中的微小气泡,用于溶液脱气,还可起到分散、乳化作用;
3. It can remove micro bubbles in the liquid very well for degassing, dispersion and emulsification;
4.采用新型脉冲调制电路,可调脉冲幅值均在空化阈值以上,这样可使能量大部分用在空化效应上,清洗强度提高;还可对脉冲宽度进行调节,达到对精细、贵重、形状复杂的零部件的强度柔和、细腻的清洗。
4. A new pulse modulation circuit is adopted, and the adjustable pulse amplitude is above the cavitation threshold, so that most of the energy can be used for cavitation effect and the cleaning intensity can be improved; It can also adjust the pulse width to achieve soft and delicate cleaning of fine, valuable and complex parts.
