超声波清洗机的优点

超声波清洗机的优点是:超声波清洗效果好,操作简单。人们所听到的声音是频率20-20000Hz的声波信号,高于20000Hz的声波称之为超声波,声波的传递依照正弦曲线纵向传播,产生大量小气泡 。一个原因是液体内局部出现拉应力而形成负压,压强的降低使原来溶于液体的气体过饱和,而从液体逸出,成为小气泡;另一原因是强大的拉应力把液体"撕开"成一空洞,称为空化。
The advantages of ultrasonic cleaning machine are: good ultrasonic cleaning effect, simple operation. The sound that people hear is the sound wave signal with the frequency of 20-20000 Hz. The sound wave with the frequency higher than 20000 Hz is called the ultrasonic wave. The transmission of the sound wave propagates longitudinally according to the sine curve, producing a large number of small bubbles. One reason is that the local tensile stress in the liquid forms a negative pressure, and the decrease of the pressure makes the gas originally dissolved in the liquid supersaturated, and then escapes from the liquid, becoming a small bubble; the other reason is that the strong tensile stress "tears" the liquid into a cavity, which is called cavitation.
