    超声波清洗机的核心结构及特点
    2016-6-7 15:10:09
    超声波换能器常用的一种压电换能器,由锆钛酸铅或其他陶瓷制成。 将压电材料放入电压变化的电场中时,它会发生变形,这就是所谓的’压电效应’。无论使用何种换能器,通常最基本的因素为其产生的空化效应的强度。
    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.
    超声波和其它声波一样,是一系列的压力点,即一种压缩和膨胀交替的波(如下图示)。如果声能足够强,液体在波的膨胀阶段被推开,由此产生气泡;而在波的压缩阶段,这些气泡就在液体中瞬间爆裂或内爆,产生一种非常有效的冲击力,特别适用於清洗。这个过程被称做空化作用。从理论上分析,爆裂的空化泡会产生超过10,000 psi的压力和20,000°F (11,000°C) 的高温,并在其爆裂的瞬间冲击波会迅速向外辐射。单个空化泡所释放的能量很小,但每秒钟内有几百万的空化泡同时爆裂,累计起来的效果将是非常强烈的,产生的强大的冲击力将工件表面的污物剥落,这就是所有超声清洗的特点。
    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.
    可以说超声波清洁是我们的生活发展中相当重要的一种生活使用方式,这种设备使用的目的就是为了能够对一些拥有特殊清洁要求或者人力无法清洁或清洁干净的物质。希望大家能够谨慎使用超声波清洁设备,正确看待超声波带来的好处和坏处。
    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.
