Degassing effect of ultrasonic cleaning instrument

超声波作用于清洗溶液中时，会产生交替工作压力，用于超声空化阀的超声波在清洗溶液中传递时可以产生超声空化气泡，能够明显提升气体从清洗溶液中到气泡的传输速率。空化气泡是由清洗溶液中的微小气核产生，在超声波稀疏相应的负压力作用会产生这些空泡。如果负压力在空化气泡形成后继续存在，那么此时空化气泡会扩张到原来尺寸的许多倍，在这种状况下，空化气泡之后不断地增大爆破。超声波清洗机脱气功能作用时，清洗溶液中气体可通过定向扩散进入空化气泡，当气泡爆破时气体会从中逸出，这产生了脱气作用。

When the ultrasonic wave acts on the cleaning solution, it will generate alternate working pressure. When the ultrasonic wave used for the ultrasonic cavitation valve is transmitted in the cleaning solution, it can generate ultrasonic cavitation bubbles, which can significantly improve the transmission rate of gas from the cleaning solution to the bubbles. Cavitation bubbles are generated by tiny gas nuclei in the cleaning solution, and these bubbles will be generated under the corresponding negative pressure of ultrasonic thinning. If the negative pressure continues to exist after the formation of the cavitation bubble, then the cavitation bubble will expand to many times the original size, in this case, the cavitation bubble will continue to increase after the explosion. When the degassing function of the ultrasonic cleaner works, the gas in the cleaning solution can enter the cavitation bubble through directional diffusion, and the gas will escape from the bubble when it bursts, which produces degassing effect.

超声波清洗仪器脱气功能主要是运用超声的定向扩散，一旦清洗溶液产生空化，里面还是有空气存在的，脱气功能是将清洗液体的空气排掉，减少超声波空化反应产生的气泡阻力，增强超声波清洗机的清洗效率，能更好达到清洗目的，提高清洗效果。另外，将清洗液中气体排出后，工件在空气残存极少的环境下清洗，可以有效在清洗过程中产生氧化的问题

The degassing function of the ultrasonic cleaning instrument is mainly to use the directional diffusion of ultrasonic. Once the cleaning solution has cavitation, there is still air in it. The degassing function is to exhaust the air of the cleaning liquid, reduce the bubble resistance generated by the ultrasonic cavitation reaction, and enhance the cleaning efficiency of the ultrasonic cleaning machine, which can better achieve the cleaning purpose and improve the cleaning effect. In addition, after the gas in the cleaning solution is discharged, the workpiece can be cleaned in an environment with very little residual air, which can effectively solve the problem of oxidation during the cleaning process

超声波清洗仪器变波的作用

Effect of ultrasonic wave on cleaning instrument

现在的超声波清洗仪器几乎都配有双功率，而变波的作用是用来改变超声波功率，从而改变清洗效果的。超声波功率不一样，进行空化的效应的结果也不一样，功率增大，产生的气泡越大，穿透性越弱，但是清洗表面的力度越强。功率降低，产生的气泡变小，穿透性越强，但是相应的清洗力度越小。

Nowadays, almost all ultrasonic cleaning instruments are equipped with dual power, and the role of variable wave is to change the ultrasonic power, thus changing the cleaning effect. The ultrasonic power is different, and the effect of cavitation is also different. With the increase of power, the larger the bubbles produced, the weaker the penetration, but the stronger the cleaning force of the surface. The lower the power, the smaller the bubbles produced, the stronger the penetration, but the smaller the corresponding cleaning force.

超声波清洗仪器扫频的作用

Function of frequency sweep in ultrasonic cleaning instrument

超声波清洗仪器工作在一个固定频率有较大的局限性，由于某些参数，如水温、清洗量等的变化，容易产生谐振频率的漂移，从而影响到清洗效果。扫频是在清洗过程中超声波频率在合理的范围内往复扫动，这种工作模式即可以避免因单一频率连续高频振动而对零件造成的共振损坏，又能够优化清洗槽中空化气泡的分布，从而进一步提升清洗效果。

The ultrasonic cleaning instrument has great limitations when working at a fixed frequency. Due to the change of some parameters, such as water temperature, cleaning volume, etc., it is easy to produce the drift of resonance frequency, which affects the cleaning effect. Sweep frequency is the ultrasonic frequency that sweeps back and forth in a reasonable range during the cleaning process. This working mode can not only avoid the resonance damage to the parts caused by continuous high-frequency vibration of a single frequency, but also optimize the distribution of cavitation bubbles in the cleaning tank, thus further improving the cleaning effect.
