    影响超声波清洗机频率的决定因素?
    2020-3-9 14:59:40

      当工作频率很低时(在人的听觉范围内)就会产生噪音。当频率低于20kHz时,工作噪音不仅会变得非常大,而且可能会超过《职业安全卫生法》或其他法规规定的安全噪声限度。在不考虑工件表面损伤的情况下需要高功率去除污垢的应用中,通常选择较低的清洗频率,从20kHz到30kHz。该频率范围内的清洗频率通常用于大型、重型零件或高密度材料的清洗。20KHz的磁性换能器和25KHz的压电换能器。

      When the working frequency is very low (in the range of human hearing), noise will be produced. When the frequency is lower than 20kHz, the working noise will not only become very large, but also may exceed the safety noise limit specified in the occupational safety and health law or other regulations. In the application of high power to remove dirt without considering the surface damage of workpiece, the lower cleaning frequency is usually selected, from 20kHz to 30kHz. The cleaning frequency in this frequency range is usually used for cleaning large, heavy parts or high-density materials. 20kHz magnetic transducer and 25kHz piezoelectric transducer.

      高频通常用于清洁小、复杂的部件或去除微小颗粒。高频也用于不允许表面损伤的应用场合。使用高频可以在几个方面改善清洁性能。随着频率的增加,空化气泡的数量直线增加,产生多密集的激波,可以进入小的间隙。在功率不变的情况下,空化泡变小,释放的能量相应减少,从而有效地减少了对工件表面的损伤。高频的另一个优点是粘性边界层(penuri效应)减少,允许超声波探测非常小的粒子。这类似于你可以在水位下降时看到河底的卵石的情况。

      High frequency is often used to clean smaller, more complex components or remove tiny particles. High frequency is also used in applications where surface damage is not allowed. Using high frequency can improve cleaning performance in several ways. With the increase of frequency, the number of cavitation bubbles increases in a straight line, resulting in more and more intensive shock waves, which can enter into smaller gaps. Under the condition of constant power, the cavitation bubble becomes smaller and the energy released correspondingly decreases, thus effectively reducing the damage to the workpiece surface. Another advantage of high frequency is the reduction of the viscous boundary layer (penuri effect), which allows ultrasonic detection of very small particles. This is similar to the situation where you can see pebbles at the bottom of the river when the water level drops.
