Cleaning of the engine parts such as the cylinder head of the ultrasonic cleaning machine has always been a headache. Due to the complicated internal cavity of these parts, the internal iron scraps, sticky sand and other debris are difficult to remove, so the cleanliness is very good. Unstable, often out of tolerance.

 

 

超声波清洁机发动机气缸盖等箱体类零件的清洁一直是令人头痛的技能难题, 由于这类零件的内腔比较复杂,内部的铁屑、粘砂等杂物很难去掉, 所以清洁度很不安稳, 常常超差。

In terms of the cleanliness of the cylinder head, despite the skill research, many methods have been taken, such as strengthening the swarf of each finishing station. ; Improve the existing cleaning equipment. ; Reduce the circulation period of the workpiece ; Add labor Finishing, etc., still did not reach the role of ambition, after all, it must rely on the traditional soaking skills to complete. Soaking is also possible for smaller batches of production, but for large-volume production, due to the long cleaning time, the production cycle is not satisfactory, so the cost will be added.

 

 

在缸盖的清洁度方面, 尽管进行了技能攻关, 采取了许多方法, 如加强各整理工位的去屑; 改善现有清洁设备才能; 减少工件的流通周期; 添加人工整理等, 仍然没有抵达抱负的作用, 终究还得靠传统的浸泡技能来完结。浸泡对于批量较小的出产还可以, 但对于大批量出产来说,由于清洁时间长, 出产节拍不能满意, 故而成本会随之添加。

To thoroughly solve the cleanliness problem, it is necessary to choose new skills and new equipment. Nowadays, many companies use ultrasonic cleaner cleaning equipment for cleaning. The following is a brief introduction to the principles and applications of ultrasonic cleaning skills.

 

 

要彻底解决清洁度疑问, 有必要选用新技能新设备。现在制作工作许多公司就利用了超声波清洁机清洁设备来进行清洁。以下就超声波清洁技能的原理及应用作些介绍。

The ultrasonic wave conveyed in the liquid can clean the dirt on the surface o全自动超声波清洗机f the object, and the principle can be explained by the phenomenon of 'cavitation' and the 'fractional effect of the ultrasonic wave in the liquid' \u0026ldquo;cavitation\u0026rdquo^ There is close contact with fen^ intensity. The ultrasonic vibration of the ultrasonic cleaner is transmitted in the liquid. When the sound pressure reaches an atmospheric pressure, the power density of the ultrasonic wave is about 0.35 W/cm2. At this time, the peak of the acoustic pressure of the ultrasonic wave transmitted in the liquid can easily reach the vacuum or the negative pressure. ; But there is actually no negative pressure phenomenon, so a large force occurs in the liquid, which breaks the liquid molecules into a hollow (cavitation nucleus), which is vacuum or very close to the vacuum, which is empty The signal voltage (or ultrasonic pressure) value reaches the maximum one and a half weeks later.

 

 

在液体中传达的超声波能对物体表面的污物进行清洁, 其原理可用“空化”现象来解说, 清洁作用和超声波在液体中发作的“空化”强度有接近的联络。超声波清洁机超声波振荡在液体中传达, 当其声波压强抵达一个大气压时, 超声波的功率密度约为0.35W/cm2, 这时在液体中传达的超声波的声波压强峰值就可以简单抵达真空或负压; 但实际上是无负压现象存在的, 因此在液体中发作一个很大的力, 将液体分子拉裂成空泛(空化核), 此空泛为真空或非常靠近真空, 此空泛在信号电压(或超声波压强)值下一个半周抵达最大时。

Due to the increase of the surrounding pressure, it is crushed. At this moment, the liquid molecules violently collide with the very strong impact. The ultrasonic cleaner will hit the dirt on the surface of the cleaned object. These many fine and dense bubbles split when they hit the shock wave. The phenomenon is called \u0026ldquo;cavitation \u0026 rdquo;. This cavitation is very simple at the junction of solid and liquid, and therefore has an extraordinary cleaning effect on objects in the liquid immersed in ultrasound. In addition, since the ultrasonic wave has a strong function of penetrating solids, it can penetrate to the other side surface of the object to be cleaned, and all the inner cavity, blind hole, slit, which is immersed in the medium, and the dust attached to the surface of the cleaning object. Drop and reach the perfect cleansing effect.

 

 

由于周围压力的增大而被压碎, 此刻液体分子剧烈磕碰发作非常强壮的冲击力, 超声波清洁机将被清洁物体表面的污物碰击下来, 这些许多纤细而密布的气泡分裂时发作冲击波的现象被称之为“空化”作用。这种空化作用非常简单在固体与液体的交界处发作, 因此对于浸入超声作用下液体中的物体具有超乎寻常的清洁作用。别的,由于超声波具有很强的穿透固体的作用, 可以穿透到被清洁物的另一侧表面, 以及全部浸入介质中的内腔、盲孔、狭缝, 将清洁物表面附着的尘垢掉落, 抵达完美的清洁作用。

Ultrasonic cleaning machine ultrasonic wave also has emulsification neutralization effect, which can be more useful to prevent the cleaned oil from sticking to the object to be cleaned. Therefore, this kind of \u0026ldquo;cavitation\u0026rdquo; can clean the inner surface of the object (such as pipe fittings and box parts) in the liquid under the action of ultrasonic waves, which is important for ultrasonic cleaning over other cleaning methods. aspect.

 

 

一起超声波清洁机超声波还有乳化中和作用, 能更有用避免被清洁掉的油污从头附着在被清洁物件上。所以这种“空化”作用对浸入超声波作用下的液体中物体表里表面(如管件、箱体件) 均能得到清洁, 这是超声波清洁优于其它清洁方法的重要方面。
