超聲波清洗機在CSSD中（zhōng）得到了廣泛的應用，但對超聲波清洗機的理解和監控似乎（hū）遠不如自動清洗機。如果大家都（dōu）知道（dào）超聲波清洗（xǐ）的（de）主要（yào）機理是“空（kōng）化（huà）效應”，那91污就來問自（zì）己（jǐ）一個問題：什麽是空（kōng）化（huà）效應（yīng）

Ultrasonic cleaning machine has been widely used in CSSD, but the understanding and monitoring of ultrasonic cleaning machine seems far less than automatic cleaning machine. If we all know that the main mechanism of ultrasonic cleaning is "cavitation effect", let's ask ourselves a question: what is cavitation effect

超聲波是一種（zhǒng）機械波，可以分為兩種類型。其中一種叫做橫（héng）波，就像水波和小麥風浪一樣。波浪上方的每一點（diǎn）都是（shì）上下起伏的，垂直於其傳播方向，會產生波峰和波穀。另一種叫做縱波，類（lèi）似於彈簧振動。波上（shàng）各點的（de）運動方向與其傳播方向一致，產生稀疏部分和（hé）密集部分。超聲（shēng）波是一種產生空化效應的（de）方法

Ultrasonic wave is a kind of mechanical wave, which can be divided into two types. One of them is called shear wave, just like water wave and wheat wind wave. Every point above the wave is undulating up and down, perpendicular to its propagation direction, will produce a crest and trough. The other is called longitudinal wave, which is similar to spring vibration. The motion direction of each point on the wave is consistent with its propagation direction, resulting in sparse part and dense part. Ultrasonic wave is a method to produce cavitation effect

將液體加入罐中，通電後將電能轉化為（wéi）超聲（shēng）波的機械（xiè）能。由於（yú）超聲波是一種密（mì）度變化，液體的壓力也隨之變化。在某一點上，當（dāng）液體處於稀疏部分時，壓力（lì）相當於負壓，水被“撕開”，中間出現真空氣泡；然（rán）後點變（biàn）為稠密部分，壓縮力增大，小的真空氣泡在聲場的作用下被向內擠（jǐ）壓破裂，氣泡（pào）在液體中不斷（duàn）產生，迅速長大，然後突然閉合。在（zài）關閉瞬間，產生強烈的衝擊波，在衝擊波的作用下（xià），汙垢（gòu）層被剝離。這是“空化”的過程

The liquid is added into the tank, and the electric energy is converted into the mechanical energy of ultrasonic after being electrified. Because ultrasonic wave is a kind of density change, the pressure of liquid also changes. At a certain point, when the liquid is in the sparse part, the pressure is equivalent to the negative pressure, the water is "torn", and a vacuum bubble appears in the middle; Then the point becomes dense part, the compression force increases, the small vacuum bubble is squeezed inward and ruptured under the action of sound field, the bubble is constantly generated in the liquid, grows rapidly, and then suddenly closes. At the moment of closing, a strong shock wave is generated. Under the action of the shock wave, the dirt layer is peeled off. This is the process of "cavitation"

需要注意的是，這裏的“氣泡”和“爆炸”不同於91污每天看到的“氣球吹”和“氣球爆炸”。水更流動，因為水裏沒（méi）有空間（jiān）。它隻（zhī）是一個被（bèi）縱波形成的相對負壓撕裂的小空間。它的爆炸不是向外爆炸（zhà），而是向內收縮，恢複液體的連續（xù）狀態

It should be noted that the "bubble" and "explosion" here are different from the "balloon blowing" and "balloon explosion" we see every day. The water is more fluid because there is no space in it. It is just a small space torn by the relative negative pressure formed by the longitudinal wave. Its explosion is not outward explosion, but inward contraction, to restore the continuous state of liquid
