研究证明，当超声波作用于液体时，液体中每一个气泡的破裂都会产生能量巨大的冲击波，相当于瞬间产生数百度高温和数千大气压。这种现象被称为“空化效应”。
It has been proved that when ultrasound acts on liquid, every bubble in the liquid will produce a shock wave with huge energy, which is equivalent to several times of high temperature and thousands of atmospheric pressure in a moment. This phenomenon is called "cavitation effect".
超声波清洗只是利用液体中气泡破裂产生的冲击波对工件内外表面进行清洗，超声波在液体中传播，使液体和清洗罐在超声波频率下一起振动。当液体和清洗槽振动时，它们有自己的固有频率，也就是声波的频率，所以人们能听到嗡嗡声。我们在使用过程应该注意什么？
Ultrasonic cleaning is carried out under the ultrasonic cleaning of the liquid, and the vibration wave propagates on the surface of the liquid. When liquids and cleaning tanks vibrate, they have their own natural frequencies, that is, the frequency of sound waves, so people can hear the hum. What should we pay attention to in the use process?
1.超声波清洗机清洁要做到位，不运用时关掉电源。
1. The cleaning of ultrasonic cleaning machine should be done in place, and the power should be turned off when not in use.
2.不要对超声波清洗机实施碰撞或强烈震惊。
启航彩2. Do not collide or shock the ultrasonic cleaner.

3.远离热源。清洗液应及时沉淀、过滤或转换，以保证清洗成果。
3. Keep away from heat sources. The cleaning solution should be precipitated, filtered or converted in time to ensure the cleaning results.
4.严禁从超声波控制柜顶端的进风口处溅入导电液体（如水）。否则会对超声波清洗机的线路体系构成严峻伤害。
4. Do not splash conductive liquid (such as water) into the air inlet at the top of the ultrasonic control cabinet. Otherwise, it will cause severe damage to the circuit system of ultrasonic cleaning machine.
5.机器应避免在湿润的环境下寄放。
5. The machine should not be placed in wet environment.
6.经长时刻运转的清洗机，在停机前应首先将功率旋钮调至零位，运用其风机再任务3-6分钟后关机，以保证电源内部热量散出。
6. For the cleaning machine running for a long time, the power knob should be set to zero before shutdown, and the fan should be shut down after 3-6 minutes of task, so as to ensure that the heat inside the power supply is dissipated.
7.机器连续任务时刻不得超过24小时，如连续任务时刻过长：应旋转超音调度旋钮至"0"位，而让散热电扇继承任务，在超声波清洗不发动的情况下为超声波控制柜内连续散热至少2分钟。
启航彩7. The continuous task time of the machine shall not exceed 24 hours. If the continuous task time is too long, turn the ultrasonic dispatching knob to "0" position, and let the heat dissipation fan inherit the task, and continuously heat the ultrasonic control cabinet for at least 2 minutes when the ultrasonic cleaning is not started.
