小型超聲波清洗機(jī)與干冰清洗機(jī)具有相同的清洗效果,但其適用范圍卻大不相同。讓我們來看看這兩者的應(yīng)用領(lǐng)域。
Small ultrasonic cleaning machine has the same cleaning effect as dry ice cleaning machine, but its application range is quite different. Let's look at the application areas of both.
在小型超聲波清洗機(jī)中,由超音波頻率計(jì)引起的高頻波動(dòng)數(shù)據(jù)信號(hào)通過超音波超聲波換能器(振動(dòng)器)轉(zhuǎn)換成高頻機(jī)械設(shè)備波動(dòng)并傳輸?shù)揭后w中。超音波在液體中以分散的方式向前輻射,產(chǎn)生數(shù)十萬個(gè)微小氣泡。
In the small ultrasonic cleaning machine, the high frequency fluctuation data signal caused by ultrasonic frequency meter is converted into high frequency mechanical equipment fluctuation by ultrasonic transducer (vibrator) and transmitted to liquid. Ultrasound radiates forward in a dispersive manner in liquid, producing hundreds of thousands of tiny bubbles.
這種氣泡在整個(gè)傳輸過程中在負(fù)壓區(qū)產(chǎn)生和發(fā)展,在正壓力區(qū)迅速閉合。在這種被稱為“空化”的小型超聲波清洗機(jī)的整個(gè)過程中,氣泡閉合會(huì)導(dǎo)致數(shù)千個(gè)大氣壓瞬間爆裂。恒壓會(huì)破壞小塊表層,使小塊表層和縫隙上的污垢迅速脫落,從而保證清洗的實(shí)際效果。
This kind of bubble is produced and developed in the negative pressure region and closed rapidly in the positive pressure region. During the whole process of this small ultrasonic cleaning machine, which is called cavitation, the bubble closure will cause thousands of atmospheres to burst instantaneously. Constant pressure will destroy the surface layer of small pieces and make the dirt on the surface and crevice fall off quickly, so as to ensure the actual effect of cleaning.
雖然小型超聲波清洗機(jī)在清洗小物體方面的預(yù)期效果優(yōu)于傳統(tǒng)的清洗方法,但由于功率和頻率不同,適當(dāng)?shù)膽?yīng)用可以保證清洗的預(yù)期效果,事半功倍。由于空化侵蝕是沿高聲強(qiáng)帶不均勻地產(chǎn)生的,當(dāng)清洗塊在清洗液中就位時(shí),空化侵蝕產(chǎn)生的不均勻性將導(dǎo)致清洗的不均勻性。為了這個(gè)問題,小型超聲波清洗機(jī)一般采用以下兩種合理的方式:
Although the expected effect of small ultrasonic cleaning machine in cleaning small objects is better than the traditional cleaning method, due to the different power and frequency, appropriate application can ensure the expected effect of cleaning, and get twice the result with half the effort. Because cavitation erosion is generated unevenly along the high sound intensity band, when the cleaning block is in place in the cleaning solution, the non-uniformity caused by cavitation erosion will lead to the non-uniformity of cleaning. In order to solve this problem, small ultrasonic cleaning machine generally adopts the following two reasonable ways:
1、移動(dòng)清洗對(duì)象位置
1. Move cleaning object position
當(dāng)清潔塊在清潔槽中移動(dòng)時(shí),唇部可以更均勻地作用在清潔塊的表面上。一個(gè)好的方法是通過旋轉(zhuǎn)清潔小塊,并讓具有強(qiáng)氣蝕的部分作用在小塊的不同表面上。
When the cleaning block moves in the cleaning groove, the lip can act more evenly on the surface of the cleaning block. A good way is to clean the small pieces by rotating them and let the parts with strong cavitation act on the different surfaces of the small pieces.
2.添加或減少一些清洗液
2. Add or reduce some cleaning fluid
當(dāng)清洗槽中的液位顯示從左到右變化時(shí),氣穴中非常響亮和強(qiáng)烈的帶的位置也發(fā)生變化,從而了汽化的不均勻性。
When the liquid level display in the cleaning tank changes from left to right, the position of the very loud and strong band in the cavitation also changes, so as to solve the non-uniformity of vaporization.
對(duì)于干冰清洗機(jī),液氮用于根據(jù)壓力清洗物體表面。由于溫差大,物體表面的污漬變得易碎,這促使它們?cè)谄茐男缘膲毫ο卤?。干冰清潔機(jī)應(yīng)采用噴槍的方式進(jìn)行,因此它可以處理金屬表面的非常大的物體,如油漆和其他污垢有很強(qiáng)的附著力。小型清洗機(jī)適用于清洗中小型物品。
For dry ice cleaners, liquid nitrogen is used to clean the surface according to pressure. Due to the large temperature difference, stains on the surface of objects become fragile, which causes them to be removed under destructive pressure. The dry ice cleaner should be carried out by means of spray gun, so it can handle very large objects on metal surface, such as paint and other dirt, and has strong adhesion. Small cleaning machine is suitable for cleaning small and medium-sized articles.
