小型超声波清洗机与干冰清洗机具有相同的清洗效果，但其适用范围却大不相同。让我们来看看这两者的应用领域。

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.

在小型超声波清洗机中，由超音波频率计引起的高频波动数据信号通过超音波超声波换能器(振动器)转换成高频机械设备波动并传输到液体中。超音波在液体中以分散的方式向前辐射，产生数十万个微小气泡。

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.

这种气泡在整个传输过程中在负压区产生和发展，在正压力区迅速闭合。在这种被称为“空化”的小型超声波清洗机的整个过程中，气泡闭合会导致数千个大气压瞬间爆裂。恒压会破坏小块表层，使小块表层和缝隙上的污垢迅速脱落，从而保证清洗的实际效果。

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.

虽然小型超声波清洗机在清洗小物体方面的预期效果优于传统的清洗方法，但由于功率和频率不同，适当的应用可以保证清洗的预期效果，事半功倍。由于空化侵蚀是沿高声强带不均匀地产生的，当清洗块在清洗液中就位时，空化侵蚀产生的不均匀性将导致清洗的不均匀性。为了这个问题，小型超声波清洗机一般采用以下两种合理的方式：

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、移动清洗对象位置

1. Move cleaning object position

当清洁块在清洁槽中移动时，唇部可以更均匀地作用在清洁块的表面上。一个好的方法是通过旋转清洁小块，并让具有强气蚀的部分作用在小块的不同表面上。

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.添加或减少一些清洗液

2. Add or reduce some cleaning fluid

当清洗槽中的液位显示从左到右变化时，气穴中非常响亮和强烈的带的位置也发生变化，从而了汽化的不均匀性。

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.

对于干冰清洗机，液氮用于根据压力清洗物体表面。由于温差大，物体表面的污渍变得易碎，这促使它们在破坏性的压力下被。干冰清洁机应采用喷枪的方式进行，因此它可以处理金属表面的非常大的物体，如油漆和其他污垢有很强的附着力。小型清洗机适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.
