超声波清洗机综合全面知识概述_济南洁升超声波清洗机
Ultrasonic ultrasonic cleaner refers to sound waves that are invisible to the human ear. A normal person's hearing can hear 16-20 kHz (KHZ) sound waves, a sound wave below 16 kHz is called an infrasound or a subsonic wave, and a sound wave that exceeds 20 kHz is called an ultrasonic wave.
2. Ultrasonic cleaner ultrasonic generation:
所谓超声波清洁器超声波，是指人耳听不见的声波。正常人的听觉能够听到16-20千赫兹（KHZ）的声波，低于16千赫兹的声波称为次声波或亚声波，超越20千赫兹的声波称为超声波。
Two main parameters of ultrasound:
⒉超声波清洁器超声波的发生：
Frequency: F\u0026ge;20KHz;
超声波的两个主要参数：
Power density: p = transmit power (W) / emission area (cm2); general p\u0026ge;0.3w/cm2.
频率：F≥20KHz；
The ultrasonic cleaner ultrasonic wave conveyed in the liquid can clean the dirt on the surface of the object, and the principle can be explained by the scene of the air vibration transmitted by the ultrasonic vibration when the ultrasonic wave reaches the atmospheric pressure. The power density is 0.35w/cm2. At this time, the peak value of the ultrasonic wave pressure can reach the vacuum or the negative pressure, but in practice no negative pressure exists, so a large force occurs in the liquid, and the liquid molecules are pulled into the air. A cavitation nucleus.
功率密度：p=发射功率（W）/发射面积（cm2）；一般p≥0.3w/cm2.
This vacancy is very close to the vacuum, which breaks when the ultrasonic pressure reaches the maximum in the opposite direction, because the strong impact of the break occurs and the dirt on the surface of the object is hit. This kind of shock wave scene caused by the breakage of many fine cavitation bubbles is called \u0026ldquo;cavitation \u0026 rdquo; scene.
在液体中传达的超声波清洁器超声波能对物体外表的污物进行清洁，其原理可用“空化”景象来解说：超声波振动在液体中传达的音波压强到达一个大气压时，其功率密度为0.35w/cm2，这时超声波的音波压强峰值就可到达真空或负压，但实践上无负压存在，因此在液体中发生一个很大的力，将液体分子拉裂成空泛一空化核。
3. The cavitation effect of ultrasonic cleaner ultrasonic wave
此空泛十分挨近真空，它在超声波压强反向到达最大时决裂，因为决裂而发生的强烈冲击将物体外表的污物碰击下来。这种由很多细微的空化气泡决裂而发生的冲击波景象称为“空化”景象。

⒊超声波清洁器超声波的空化效应
a. Cleaning media:
超声波清洁器清洁效果及有关参数：
Ultrasonic cleaners are used for ultrasonic cleaning. There are generally two types of cleaners: chemical cleaners and water-based cleaners. The cleaning medium is a chemical effect, and the ultrasonic cleaning is a physical effect, and the two effects are combined to make the object fully and completely clean.
a超声波清洗机.清洁介质：
b. Power density:
选用超声波清洁器超声波清洁，一般有两种清洁剂：化学清洁剂和水基清洁剂。清洁介质是化学效果，而超声波清洁是物理效果，两种效果相结合，以对物体进行充沛、完全的清洁。
The higher the power density of the ultrasonic wave, the stronger the cavitation effect, and the faster the speed, the better the cleaning effect. For objects with high precision and high surface finish, long-term high-power density cleaning will occur on the surface of the object \u0026ldquo;cavitation \u0026 rdquo; corrosion.
b.功率密度：
c. Ultrasonic frequency:
超声波的功率密度越高，空化效果越强，速度越快，清洁效果越好。单关于精密的、外表光洁度甚高的物体，选用长期的高功率密度清洁会对物体外表发生“空化”腐蚀。
The lower the ultrasonic frequency, the simpler the cavitation in the liquid and the stronger the effect. When the frequency is high, the ultrasonic direction is strong, which is suitable for precise object cleaning.
c.超声波频率：
d. Generally speaking, the ultrasonic wave has the best cavitation effect at 30oС~40oС. The higher the temperature of the cleaner, the more obvious the effect.
超声波频率越低，在液体中发生空化越简单，效果也越强。频率高则超声波方向性强，适合于精密的物体清洁。
In general practice, when applying ultrasonic cleaning, the working temperature of 30oС~60oС is selected.
d.一般来说，超声波在30oС~40oС时空化效果最好。清洁剂则温度越高，效果越明显。
4. Ultrasonic cleaner cleaning features: \u0026 ldquo ^ fen ^ ultrasonic cleaning process technology \u0026 rdquo ^ fen ^ refers to the use of ultrasonic cavitation effect on the surface of the object on the dirt hit, peel, in order to reach the cleaning intention. Ultrasonic cleaners feature high cleanliness and fast cleaning. Especially for blind holes and various kinds of objects, there are special cleaning effects that cannot be reached by other cleaning methods.
