What should be paid attention to when purchasing ultrasonic cleaner

After the requirements are defined, the appropriate products are selected according to the requirements. What should be paid attention to when purchasing ultrasonic cleaners:

1. size and material of cleaning tank

The material of the cleaning tank shall be determined according to the chemical characteristics of the cleaning medium. SUS304 stainless steel is the most commonly used. If the environment is harsh, SUS316 material can be selected.

The size of the cleaning tank shall determine the minimum effective volume according to the overall size and quantity of the cleaned articles. In addition, pay attention to the mesh size of the cleaning basket. When cleaning small parts, the basket is often used. Because the mesh will cause ultrasonic attenuation, it is better to use a mesh of more than 10mm when the frequency is 28kHz.

2. selection of power frequency band

The power of the ultrasonic cleaner has a great influence on the cleaning effect. The frequency of the ultrasonic cleaner is generally in the range of 20kHz to 100kHz. It is obviously more effective to use low frequency when using water or water cleaning solution. The conventional cleaning frequencies are 28kHz and 40KHz, and the higher frequency is used only when the workpiece surface requires very small particles and the surface is not allowed to be damaged. The frequency range of 40 to 60KHZ can be selected for precision parts.

3. cleaning process related functions

The cleaning method shall be determined according to the material and dirt properties of the workpiece to be cleaned. The chemical components in most cleaning solutions will achieve the best cleaning effect at a certain temperature, so the heating function is essential. In addition, the functions related to the cleaning process of the ultrasonic cleaner include: setting the ultrasonic working time, ultrasonic power, heating temperature, etc.

4. other functions

In addition to the functions that meet the basic requirements, other functions should be considered. For example, is there a touch panel, mute function, manual, semi-automatic or fully automatic, integrated or split?

Generally speaking, the manual cleaner is suitable for small amount cleaning operation with simple process. Semi automatic cleaning is suitable for large-scale heavy objects or medium and large batches; Automatic cleaning has stable quality and good effect, but the equipment cost is high, which is suitable for mass cleaning.

The all-in-one desktop is smaller and saves space. The multi slot ultrasonic cleaner often separates the generator from the wet cleaning environment. The multi slot ultrasonic cleaner is often customized according to the actual situation of the user.

5. selection of cleaning solution

In addition to the ultrasonic cleaner, you should also select the appropriate cleaner according to the material of the workpiece to be cleaned and the nature of the dirt. Cleaning agents are divided into organic solvents and water-based cleaning agents.

The cleaning agent shall be safe and non-toxic, easy to operate, with high cleaning sales and long service life. The use of solvent cleaning agents often requires a continuous waste liquid recovery device.

After screening the ultrasonic cleaners according to their needs and functions, what is left is to select a product with appropriate brand and price within the range of options.
