超聲波清洗儀器脫氣的作用
Degassing effect of ultrasonic cleaning instrument
超聲波作用于清洗溶液中時,會產(chǎn)生交替工作壓力,用于超聲空化閥的超聲波在清洗溶液中傳遞時可以產(chǎn)生超聲空化氣泡,能夠明顯提升氣體從清洗溶液中到氣泡的傳輸速率??栈瘹馀菔怯汕逑慈芤褐械奈⑿夂水a(chǎn)生,在超聲波稀疏相應的負壓力作用會產(chǎn)生這些空泡。如果負壓力在空化氣泡形成后繼續(xù)存在,那么此時空化氣泡就會擴張到原來尺寸的許多倍,在這種狀況下,空化氣泡之后不斷地增大爆破。超聲波清洗機脫氣功能作用時,清洗溶液中氣體可通過定向擴散進入空化氣泡,當氣泡爆破時氣體會從中逸出,這就產(chǎn)生了脫氣作用。
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.
超聲波清洗儀器脫氣功能主要是運用超聲的定向擴散,一旦清洗溶液產(chǎn)生空化,里面還是有空氣存在的,脫氣功能就是將清洗液體的空氣排掉,減少超聲波空化反應產(chǎn)生的氣泡阻力,增強超聲波清洗機的清洗效率,能更好達到清洗目的,提高清洗效果。另外,將清洗液中氣體排出后,工件在空氣殘存極少的環(huán)境下清洗,可以有效解決在清洗過程中產(chǎn)生氧化的問題
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
超聲波清洗儀器變波的作用
Effect of ultrasonic wave on cleaning instrument
現(xiàn)在的超聲波清洗儀器幾乎都配有雙功率,而變波的作用就是用來改變超聲波功率,從而改變清洗效果的。超聲波功率不一樣,進行空化的效應的結果也不一樣,功率增大,產(chǎn)生的氣泡越大,穿透性越弱,但是清洗表面的力度越強。功率降低,產(chǎn)生的氣泡變小,穿透性越強,但是相應的清洗力度就越小。
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.

超聲波清洗儀器掃頻的作用
Function of frequency sweep in ultrasonic cleaning instrument
超聲波清洗儀器工作在一個固定頻率有較大的局限性,由于某些參數(shù),如水溫、清洗量等的變化,容易產(chǎn)生諧振頻率的漂移,從而影響到清洗效果。掃頻是在清洗過程中超聲波頻率在合理的范圍內(nèi)往復掃動,這種工作模式即可以避免因單一頻率連續(xù)高頻振動而對零件造成的共振損壞,又能夠優(yōu)化清洗槽中空化氣泡的分布,從而進一步提升清洗效果。
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.
