来源:/ 时间: 2022-04-14 浏览次数: 2

实验室作为科学研究的摇篮,每天需要进行各类实验,在实验过程中使用的各种仪器配件、容器 、工具如试管、烧杯、载玻片、电子天平、棱镜、镊子、夹子等都需要完全清洁后才能用于下一次实验。而对于一些复杂的清洗对象,用手工清洗不容易洗干净。污染的仪器配件、容器、工具会影响实验数据的准确性。
As the cradle of scientific research, the laboratory needs to carry out various experiments every day. All kinds of instrument accessories, containers and tools used in the experiment, such as test tubes, beakers, glass slides, electronic scales, prisms, tweezers and clips, need to be completely cleaned before they can be used in the next experiment. For some complex cleaning objects, manual cleaning is not easy to clean. Contaminated instrument accessories, containers and tools will affect the accuracy of experimental data.
所以,越来越多的实验室意识到超声波清洗的方便性与实用性,将超声波清洗机作为实验室的必备仪器。
Therefore, more and more laboratories realize the convenience and practicability of ultrasonic cleaning, and take ultrasonic cleaning machine as the necessary instrument in the laboratory.
那么,超声波清洗机究竟是台什么样的仪器,它的工作原理是什么呢?除了用作实验室清洗,超声波清洗机还能用于哪些领域呢?
So, what kind of instrument is the ultrasonic cleaning machine and what is its working principle? In addition to being used for laboratory cleaning, what fields can ultrasonic cleaning machines be used in?
接下来我们就来一起了解一下吧。
Next, let's get to know it together.
A什么是超声波清洗?
A what is ultrasonic cleaning?
频率高于20KHz(每秒20,000次振荡)的振荡称为超声波。当这些振荡作用在液体中时,在拉伸阶段,液体中会产生数百万个微小的真空气泡,这些真空气泡在压力阶段内爆,从而产生局部高能量的压力冲击,这个过程叫做空化。与40 KHz左右的较高频率相比,28 KHz左右的低频产生更大直径的气泡,具有更强烈的压力冲击,针对不同的清洗任务应选择不同的超声频率。
Oscillations with frequencies higher than 20kHz (20000 oscillations per second) are called ultrasonic waves. When these oscillations act on the liquid, millions of tiny vacuum bubbles will be generated in the liquid in the stretching stage. These vacuum bubbles implode in the pressure stage, resulting in local high-energy pressure shock. This process is called cavitation. Compared with the higher frequency of about 40 kHz, the low frequency of about 28 kHz produces bubbles with larger diameter and stronger pressure impact. Different ultrasonic frequencies should be selected for different cleaning tasks.
B超声波是如何工作的?
How does B-ultrasound work?
空化导致污染物从清洗对象的表面、凹处和孔中被震荡出来,加上有针对性的清洗液,可以快速有效的达到清洗目的。超声波在几分钟内清洗的效率超过任何手动清洗。同时,它是温和的,因为它避免了机械损坏,也避免了化学腐蚀。
Cavitation causes pollutants to be shaken out from the surface, recess and hole of the cleaning object. With targeted cleaning fluid, the purpose of cleaning can be achieved quickly and effectively. Ultrasonic cleaning is more efficient than any manual cleaning in a few minutes. At the same time, it is mild because it avoids mechanical damage and chemical corrosion.
C选择什么尺寸的超声波清洗机?
C what size ultrasonic cleaning machine do you choose?
超声波清洗机设备
清洗对象的大小决定了清洗篮的大小,从而决定了所需设备的型号。为了使超声波能够从各个方面起用,建议选择稍大一点的设备,这也为将来扩展提供了回旋的余地。
The size of the cleaning object determines the size of the cleaning basket, which determines the model of the required equipment. In order to make ultrasound work from all aspects, it is suggested to choose a slightly larger equipment, which also provides room for future expansion.
清洗的难度取决于清洗对象的几何形状和污染物的类型。对于复杂的清洗任务,建议增加预处理工序,例如蒸汽清洗或喷淋清洗。
The difficulty of cleaning depends on the geometry of the cleaning object and the type of pollutants. For complex cleaning tasks, it is recommended to add pretreatment processes, such as steam cleaning or spray cleaning.
D超声波清洗时需要加热吗?
D do you need heating during ultrasonic cleaning?
经过加热的清洗液有利于缩短清洗时间,可以更快的去除污染物 。所以对于各类清洗对象的清洗,通常使用带有加热装置的清洗设备。
The heated cleaning solution can shorten the cleaning time and remove pollutants faster. Therefore, for the cleaning of various cleaning objects, the cleaning equipment with heating device is usually used.
E为什么超声波工作时水会变热?
E why does water get hot when ultrasound works?
带加热的超声波清洗设备具有温度设定功能,当达到设定温度时,加热器关闭,但由于超声波空化会使受作用的液体变暖,同时超声波的机械能也会有一部分转化为热能,这会导致清洗液的升温。
The ultrasonic cleaning equipment with heating has the function of temperature setting. When the set temperature is reached, the heater will be turned off. However, due to ultrasonic cavitation, the affected liquid will be warmed. At the same time, part of the mechanical energy of ultrasonic will be converted into heat energy, which will lead to the temperature rise of cleaning liquid.
F超声波会损坏零件吗?
F will ultrasonic waves damage parts?
每秒有数以千计的空化气泡内爆,这是非常强大的。然而,超声波清洗是一个非常安全的过程,因为能量处于“微观”水平, 空化气泡的直径仅为1-3纳米!
Thousands of cavitation bubbles implode every second, which is very powerful. However, ultrasonic cleaning is a very safe process, because the energy is at the "micro" level, and the diameter of cavitation bubbles is only 1-3 nm!

允许使用哪些液体?
What liquids are allowed?
请根据清洗对象的材料和污染物的类型仔细选择清洗液。不适当的清洗液会损坏零件。请勿直接在振动槽中使用易燃或爆炸性液体!
Please carefully select the cleaning fluid according to the material of the cleaning object and the type of pollutants. Improper cleaning fluid can damage parts. Do not use flammable or explosive liquids directly in the vibration tank!
是否需要保护听力?
Is hearing protection required?
如果在设备周围连续工作,建议使用听力保护器或者购买隔音箱。
If you work continuously around the equipment, it is recommended to use a hearing protector or buy a sound isolating box.
一次可以清洗多少零件?
 how many parts can be cleaned at a time?
清洗对象各部分不应重叠。在各清洗对象之间必须有足够的自由空间,散装物料必须松散分配。在此基础上,可以尽量多的放置清洗零件。
Each part of the cleaning object shall not overlap. There must be enough free space between cleaning objects, and bulk materials must be distributed loosely. On this basis, you can place as many cleaning parts as possible.
