摘要
超声波清洗具有广泛的应用,它利用的是超声空化效应。用水作为清洗液,推导出气泡闭合时在局部产生的高温、高压。并通过实验,对清洗液温度进行了测量,水温由14.70℃升高到39.70℃,温度变化25℃。在开始60 m in温度上升比较快,上升了21.10℃;随后60 m in,温度上升比较缓慢。清洗液温度在这样范围内变化,有利于空化核的形成,对清洗工件有利。
Ultrasonic wave is widely used because of its cavitation effect. When water serves as cleaning fluid, high temperature and high pressure come out from the breaking of cavitation bubbles. In the test,the temperature of cleaning fluid rises from 14.70℃ to 39.70℃. The temperature goes up fast in the first 60 minutes,which is 21.10℃ ;while in the following 60 minutes,it goes up slowly. This change of temperature in such a scope is favorable for the formation of cavitation stone, which is helpful for cleaning work.
