超聲波清洗機(jī)綜合知識(shí)簡(jiǎn)述_濟(jì)南潔升超聲波清洗機(jī)
Ultrasonic waves are transmitted in the liquid, causing the liquid to oscillate together with the cleaning tank at the ultrasonic frequency. The liquid and the cleaning tank oscillate when there is a natural frequency. This oscillation frequency is the frequency of the sound wave, so everyone hears a click. With the continuous development of the cleaning profession, the increasing number of occupations and companies have applied ultrasonic cleaning machines.The high-frequency oscillating signal declared by the ultrasonic generator on the principle of the ultrasonic cleaning machine is converted into high-frequency mechanical oscillation by the transducer and transmitted to the medium--cleaning solvent, and the ultrasonic wave is radiated in the cleaning liquid in a dense manner. The liquid activity causes tens of thousands of small bubbles having a diameter of 50-500 \u0026 mu;m, and the fine bubbles existing in the liquid oscillate under the action of the sound field.
超聲波在液體中傳達(dá)，使液體與清潔槽在超聲波頻率下一起振蕩，液體與清潔槽振蕩時(shí)有自個(gè)固有頻率，這種振蕩頻率是聲波頻率，所以大家就聽(tīng)到嗡嗡聲。跟著清潔職業(yè)的不斷發(fā)展，不斷增加的職業(yè)和公司運(yùn)用到了超聲波清潔機(jī)。
These bubbles are formed and grown in the negative pressure region conveyed by the longitudinal direction of the ultrasonic wave, and in the positive pressure region, when the sound pressure reaches a certain value, the bubble agilely increases and then closes. And when the bubble is closed, a shock wave occurs, thousands of atmospheric pressures occur around it, destroying the insoluble dirt and causing them to scatter in the cleaning liquid. When the collective particles are wrapped by the oil and adhere to the appearance of the cleaning member, the oil is emulsified and solid. Particles and detachment, then reach the cleansing of the cleaning article. In this process known as \u0026ldquo;cavitation \u0026 rdquo;, ??the bubble closure can constitute a high temperature of several hundred degrees and an instantaneous high pressure of more than 1000 atmospheres.
對(duì)超聲波清潔機(jī)原理由超聲波發(fā)生器宣布的高全自動(dòng)超聲波清洗機(jī)頻振蕩信號(hào)，經(jīng)過(guò)換能器轉(zhuǎn)換成高頻機(jī)械振蕩而傳到達(dá)介質(zhì)－－清潔溶劑中，超聲波在清潔液中疏密相間的向前輻射，使液體活動(dòng)而發(fā)生數(shù)以萬(wàn)計(jì)的直徑為50-500μm 的細(xì)小氣泡，存在于液體中的細(xì)小氣泡在聲場(chǎng)的作用下振蕩。
The advantages of the ultrasonic cleaning machine are: ultrasonic cleaning is good, and the operation is simple. The sound that everyone hears is the sound wave signal with a frequency of 20-20000 Hz. The sound wave higher than 20000 Hz is called ultrasonic wave. The sound wave is transmitted in the longitudinal direction of the sinusoidal curve, and a large number of small bubbles occur. One reason is that the inner part of the liquid exhibits a tensile stress and constitutes a negative pressure. The pressure drop causes the gas which is originally dissolved in the liquid to be supersaturated, and escapes from the liquid to become a small bubble; another reason is that the strong tensile stress brings the liquid to the ldquo^fen ^Through \u0026 rdquo; into an empty pan, called cavitation. 這些氣泡在超聲波縱向傳達(dá)的負(fù)壓區(qū)構(gòu)成、成長(zhǎng)，而在正壓區(qū)，當(dāng)聲壓到達(dá)必定值時(shí)，氣泡敏捷增大，然后俄然閉合。并在氣泡閉合時(shí)發(fā)生沖擊波，在其周?chē)l(fā)生上千個(gè)大氣壓，破壞不溶性污物而使他們渙散于清潔液中，當(dāng)集體粒子被油污裹著而黏附在清潔件外表時(shí)，油被乳化，固體粒子及脫離，然后到達(dá)清潔件凈化的意圖。在這種被稱(chēng)之為“空化”效應(yīng)的過(guò)程中，氣泡閉合可構(gòu)成幾百度的高溫和超過(guò)1000個(gè)氣壓的剎那間高壓。
超聲波清潔機(jī)的長(zhǎng)處是：超聲波清潔作用好，操作簡(jiǎn)略。大家所聽(tīng)到的聲響是頻率20-20000Hz的聲波信號(hào)，高于20000Hz的聲波稱(chēng)之為超聲波，聲波的傳遞依照正弦曲線縱向傳達(dá)，發(fā)生大量小氣泡 。一個(gè)原因是液體內(nèi)部分呈現(xiàn)拉應(yīng)力而構(gòu)成負(fù)壓，壓強(qiáng)的下降使本來(lái)溶于液體的氣體過(guò)飽和，而從液體逸出，成為小氣泡；另一原因是強(qiáng)大的拉應(yīng)力把液體“扯開(kāi)”成一空泛，稱(chēng)為空化。
