全自動(dòng)真空碳?xì)淝逑礄C(jī)主要由超聲波清洗槽和超聲波發(fā)生器組成。超聲波清洗槽采用堅(jiān)固有彈性的不銹鋼制成，底部裝有超聲波換能器振子；超聲波發(fā)生器產(chǎn)生高頻高壓，通過(guò)電纜連接線傳給換能器，換能器與振動(dòng)板共同產(chǎn)生高頻共振，使清洗槽中的溶劑受到超聲波作用。清潔污垢的動(dòng)作。

The automatic vacuum hydrocarbon cleaning machine is mainly composed of an ultrasonic cleaning tank and an ultrasonic generator. The ultrasonic cleaning tank is made of solid and elastic stainless steel, and the bottom is equipped with an ultrasonic transducer vibrator; The ultrasonic generator generates high-frequency and high-voltage, which is transmitted to the transducer through the cable connecting line. The transducer and the vibrating plate jointly generate high-frequency resonance, so that the solvent in the cleaning tank is subjected to ultrasonic action. The action of cleaning dirt.

當(dāng)聲壓或聲強(qiáng)達(dá)到一定程度時(shí)，氣泡會(huì)迅速膨脹，然后又突然關(guān)閉。在此過(guò)程中，在氣泡閉合的瞬間產(chǎn)生沖擊波，從而在氣泡周圍產(chǎn)生1012-1013pa的壓力并進(jìn)行局部溫度調(diào)節(jié)。這種超聲波空化產(chǎn)生的巨大壓力可以破壞不溶性污垢并使它們分化成溶液。蒸汽型空化對(duì)污垢的直接和反復(fù)影響。

When the sound pressure or intensity reaches a certain level, the bubble will expand rapidly and then suddenly close. In this process, a shock wave is generated at the moment when the bubble closes, resulting in a pressure of 1012-1013pa around the bubble and local temperature regulation. The huge pressure generated by this ultrasonic cavitation can destroy the insoluble dirt and make them differentiate into solutions. Direct and repeated effects of steam cavitation on fouling.

超聲波發(fā)生器將交流電轉(zhuǎn)換成超聲波頻率的功率，其頻率范圍一般為16khz-68khz，高可達(dá)1000khz。然后，電力通過(guò)電纜傳輸?shù)絺鞲衅?。超聲換能器通常由幾個(gè)平行的聲頭組成。在這里，電能轉(zhuǎn)換成同頻率的機(jī)械振動(dòng)能并傳遞到清洗槽，從而在清洗液中形成來(lái)回振動(dòng)的超聲波聲場(chǎng)。

The ultrasonic generator converts alternating current into ultrasonic frequency power. Its frequency range is generally 16khz-68khz, up to 1000khz. The power is then transmitted to the sensor by cable. Ultrasonic transducers are usually composed of several parallel sound heads. Here, the electric energy is converted into mechanical vibration energy of the same frequency and transmitted to the cleaning tank, so as to form an ultrasonic sound field that vibrates back and forth in the cleaning solution.

在超聲聲場(chǎng)中，由于周圍液體補(bǔ)給較晚，在振動(dòng)負(fù)壓區(qū)形成大量微真空氣泡。當(dāng)正壓到來(lái)時(shí)，微泡在壓力下突然閉合，液體之間的劇烈碰撞產(chǎn)生巨大的沖擊波，可形成數(shù)千至數(shù)萬(wàn)個(gè)大氣壓和瞬間高溫。這就是超聲波的“空化”效應(yīng)。氣蝕具有良好的清洗和乳化作用，可以將被清洗工件表面的油污分離出來(lái)，從而達(dá)到快速清洗的目的

In the ultrasonic field, a large number of micro vacuum bubbles are formed in the negative pressure area of vibration due to the late supply of surrounding liquid. When the barotropic pressure comes, the microbubbles suddenly close under pressure, and the violent collision between liquids produces a huge shock wave, which can form thousands to tens of thousands of atmospheres and instantaneous high temperature. This is the "cavitation" effect of ultrasound. Cavitation has good cleaning and emulsifying effects, and can separate the oil stains on the surface of the cleaned workpiece, so as to achieve the purpose of rapid cleaning

此外清潔對(duì)象的大小決定了清潔籃的大小，從而決定了所需的設(shè)備類型。為了讓超聲波能夠從各個(gè)方面發(fā)揮作用，建議選擇體積稍大的設(shè)備，這也為以后的擴(kuò)展提供了回旋余地。清潔的難度取決于被清潔物體的幾何形狀和污染的類型。對(duì)于復(fù)雜的清洗任務(wù)，建議增加蒸汽清洗或噴霧清洗等預(yù)處理步驟。加熱后的清洗液有利于縮短清洗時(shí)間，更快去除污染物。因此，對(duì)于各種清洗物的清洗，通常使用帶有加熱裝置的超聲波清洗設(shè)備。

In addition, the size of the cleaning object determines the size of the cleaning basket, thus determining the type of equipment required. In order to make ultrasonic wave play a role in all aspects, it is recommended to select equipment with a slightly larger volume, which also provides room for future expansion. The difficulty of cleaning depends on the geometry of the object to be cleaned and the type of contamination. For complex cleaning tasks, it is recommended to add pretreatment steps such as steam cleaning or spray cleaning. The heated cleaning solution can shorten the cleaning time and remove pollutants faster. Therefore, ultrasonic cleaning equipment with heating device is usually used for cleaning various cleaning materials.
