超聲波清洗機綜合全面知識概述_濟南潔升超聲波清洗機
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:
所謂超聲波清潔器超聲波，是指人耳聽不見的聲波。正常人的聽覺能夠聽到16-20千赫茲（KHZ）的聲波，低于16千赫茲的聲波稱為次聲波或亞聲波，超越20千赫茲的聲波稱為超聲波。
Two main parameters of ultrasound:
⒉超聲波清潔器超聲波的發(fā)生：
Frequency: F\u0026ge;20KHz;
超聲波的兩個主要參數(shù)：
Power density: p = transmit power (W) / emission area (cm2); general p\u0026ge;0.3w/cm2.
頻率：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=發(fā)射功率（W）/發(fā)射面積（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.
在液體中傳達的超聲波清潔器超聲波能對物體外表的污物進行清潔，其原理可用“空化”景象來解說：超聲波振動在液體中傳達的音波壓強到達一個大氣壓時，其功率密度為0.35w/cm2，這時超聲波的音波壓強峰值就可到達真空或負壓，但實踐上無負壓存在，因此在液體中發(fā)生一個很大的力，將液體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，它在超聲波壓強反向到達最大時決裂，因為決裂而發(fā)生的強烈沖擊將物體外表的污物碰擊下來。這種由很多細微的空化氣泡決裂而發(fā)生的沖擊波景象稱為“空化”景象。

⒊超聲波清潔器超聲波的空化效應(yīng)
a. Cleaning media:
超聲波清潔器清潔效果及有關(guān)參數(shù)：
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超聲波清洗機.清潔介質(zhì)：
b. Power density:
選用超聲波清潔器超聲波清潔，一般有兩種清潔劑：化學清潔劑和水基清潔劑。清潔介質(zhì)是化學效果，而超聲波清潔是物理效果，兩種效果相結(jié)合，以對物體進行充沛、完全的清潔。
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:
超聲波的功率密度越高，空化效果越強，速度越快，清潔效果越好。單關(guān)于精密的、外表光潔度甚高的物體，選用長期的高功率密度清潔會對物體外表發(fā)生“空化”腐蝕。
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.超聲波頻率：
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.
超聲波頻率越低，在液體中發(fā)生空化越簡單，效果也越強。頻率高則超聲波方向性強，適合于精密的物體清潔。
In general practice, when applying ultrasonic cleaning, the working temperature of 30oС~60oС is selected.
d.一般來說，超聲波在30oС~40oС時空化效果最好。清潔劑則溫度越高，效果越明顯。
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.
