怎樣區(qū)分超聲波細胞破碎儀和超聲波清洗設備？

作者：admin來源：http://www.lsxrst.com/時間：2021-07-22

超聲波細胞破碎儀的工作原理是基于超聲波在液體中的空化作用。傳感器利用電能通過喇叭在工具頭頂部的液體中產生高強度剪切力，形成高頻交替水壓以擴大空腔，爆炸打碎了牢房。另一方面，由于超聲波在液體中傳播時的劇烈干擾，粒子產生很大的加速度，相互碰撞或與墻壁碰撞并破裂。

The working principle of ultrasonic cell breaker is based on the cavitation effect of ultrasonic in liquid. The sensor uses electric energy to produce high-strength shear force in the liquid at the top of the tool head through the horn, forming high-frequency alternating water pressure to expand the cavity, and the explosion broke the cell. On the other hand, due to the strong interference of ultrasonic wave in liquid, particles produce a great acceleration, and collide with each other or with the wall and break.

廣泛應用于生物化學、醫(yī)藥、食品檢測、環(huán)境監(jiān)測等領域的破碎動植物組織、病毒、細菌和其他細胞結構，以及乳化、分離、均化和其他化學反應。

It is widely used in the fields of Biochemistry, medicine, food detection, environmental monitoring and so on to crush animal and plant tissues, viruses, bacteria and other cell structures, as well as emulsification, separation, homogenization and other chemical reactions.

超聲波清洗機利用超聲波發(fā)生器發(fā)出的交叉頻率信號，通過傳感器轉換成交叉頻率機械振蕩，并傳播到介質---清洗液，強超聲波以清潔液中的濃密和相間的形式輻射到被清洗的物體。發(fā)生“氣蝕”現(xiàn)象，即清潔液中以“氣泡”的形式出現(xiàn)破裂現(xiàn)象。當“空化”到達被清洗物體表面的瞬間，達到遠遠超過1000大氣壓的沖擊力，導致表面、孔、污垢中的縫隙被分散、開裂和剝落，使物體凈化和清潔。

The ultrasonic cleaning machine uses the cross frequency signal from the ultrasonic generator, which is converted into cross frequency mechanical oscillation through the sensor, and propagates to the medium --- cleaning solution. The strong ultrasonic radiation to the cleaned object in the form of dense and alternate in the cleaning solution. The phenomenon of "cavitation" occurs, that is, the phenomenon of cracking in the form of "bubbles" in the cleaning solution. When the "cavitation" reaches the surface of the object to be cleaned, the impact force is far more than 1000 atmospheric pressure, which causes the cracks in the surface, holes and dirt to be dispersed, cracked and peeled off, so as to purify and clean the object.

主要適用于商業(yè)、輕工業(yè)、高校、科研小批量清洗、脫氣、混合、提取、細胞破碎。

It is mainly suitable for small batch cleaning, degassing, mixing, extracting and cell crushing in commerce, light industry, universities and scientific research.

兩者的主要區(qū)別在于：

The main differences between the two are as follows:

超聲波清洗機和超聲波細胞破碎儀的主要原理是相同的。主要區(qū)別在于超聲波細胞破碎儀將所有能量集中在探頭上，超聲波清洗機的能量均勻分布在清洗槽的底部。因此，超聲波清洗機更傾向于脫氣和清洗，超聲波細胞破碎儀傾向于細胞破碎、乳化和均勻化。

The main principles of ultrasonic cleaning machine and ultrasonic cell crushing instrument are the same. The main difference is that the ultrasonic cell crusher concentrates all the energy on the probe, and the energy of the ultrasonic cleaning machine is evenly distributed at the bottom of the cleaning tank. Therefore, the ultrasonic cleaner is more inclined to degassing and cleaning, and the ultrasonic cell crusher is more inclined to cell crushing, emulsification and homogenization.

由于超聲波清洗機的超聲波與聲波一樣是一種疏密的振動波，介質的壓力作交替變化。以靜壓(一般一個大氣壓)為中心，產生壓力的增減，若依次增強超聲波的強度，則壓力振幅也隨著增加，并產生負的壓力。所謂負壓，但實際上負的壓力是不存在的，這是在液體中產生撕裂的力，且形成真空的空泡，并被后面的壓縮力壓擠而破滅。

Because the ultrasonic wave of the ultrasonic cleaning machine is a kind of dense vibration wave like the sound wave, the pressure of the medium changes alternately. With the static pressure (generally one atmospheric pressure) as the center, the pressure increases or decreases. If the intensity of the ultrasonic wave is increased in turn, the pressure amplitude increases and a negative pressure is generated. The so-called negative pressure, but in fact there is no negative pressure, this is the tearing force in the liquid, and the formation of a vacuum bubble, which is crushed by the compression force behind.
