    超聲波清洗機的核心結構及特點
    2019-09-13 15:10:09
    超聲波換能器常用的一種壓電換能器,由鋯鈦酸鉛或其他陶瓷製成。 將壓電材料放入電壓變化的電場中時,它會發生變形,這就是所謂的’壓電效應’。無論使用何種換能器,通常更基本的因素為其產生的空化效應的強度。
    A piezoelectric transducer used in the ultrasonic transducer, made of lead titanate or other ceramics. When the piezoelectric material is placed in the electric field of the voltage change, it will deform, which is called the "piezoelectric effect". No matter what kind of transducer is used, the most basic factor is the intensity of the cavitation effect.
    超聲波和其它聲波一樣,是一係列的壓力點,即一種壓縮和膨脹交替的波(如下圖示)。如果聲能足夠強,液體在波的膨脹階段被推開,由此產生氣泡;而在波的壓縮階段,這些氣泡就在液體中瞬間爆裂或內爆,產生一種非常有效的衝擊力,特別適用於清洗。這個過程被稱做空化作用。從理論上分析,爆裂的空化泡會產生超過10,000 psi的壓力和20,000°F (11,000°C) 的高溫,並在其爆裂的瞬間衝擊波會迅速向外輻射。單個空化泡所釋放的能量很小,但每秒鍾內有幾百萬的空化泡同時爆裂,累計起來的效果將是非常強烈的,產生的強大的衝擊力將工件表麵的汙物剝落,這就是所有超聲清洗的特點。
    Like other sound waves, the ultrasonic wave is a series of pressure points, a wave of compression and expansion (see figure below). If the energy is strong enough, liquid in the expansion phase of the wave is pushed away, the resulting bubble; and in the wave of the compression stage, the bubble is in the liquid instantaneous burst or implosion, produce a kind of very effective impact, especially for for cleaning. This process is called cavitation. From a theoretical analysis, the bursting of the cavitation bubble will produce more than 10000 psi of pressure and 20000 degree F (11000 C) at high temperatures, and the instantaneous shock waves in its burst will rapidly radiate outward. A single cavitation bubble release of energy is very small, but per second have millions of cavitation bubble burst at the same time, cumulative effect will be very strong, have a powerful impact the workpiece surface spalling of dirt, which is all the ultrasonic cleaning.
    可以說超聲波清潔是我們的生活發展中相當重要的一種生活使用方式,這種設備使用的目的就是為了能夠對一些擁有特殊清潔要求或者人力無法清潔或清潔幹淨的物質。希望大家能夠謹慎使用超聲波清潔設備,正確看待超聲波帶來的好處和壞處。
    Can be said that the ultrasonic cleaning is very important in the development of our living a life of use. Using this equipment, the purpose is in order to be able to some of the material with special cleaning requirements or human not clean or clean. I hope you can be careful to use ultrasonic cleaning equipment, the correct view of the advantages and disadvantages of ultrasonic.
