Industrial ultrasonic cleaners are an effective solution for many cleaning applications, and they often work faster and clean more thoroughly than traditional cleaning methods. Harsh chemicals and manual scrubbing can be avoided when the right ultrasonic cleaner is properly configured. The key is to choose a cleaner with the right features and functionality. Important factors to consider when selecting an industrial ultrasonic cleaner include frequency, vessel size, power, cleaning solution and operating temperature.
1, choose the best ultrasonic cleaning frequency
Ultrasonic frequency determines the energy level of the cavitation bubbles in the cleaning fluid to produce cleaning effect. Lower frequencies result in larger, more energized bubbles that are more powerful for cleaning, while higher frequencies produce smaller, low-energy bubbles. low frequencies between 25kHz and 40kHz are good for cleaning hard surfaces or removing oil, but if the part surface is soft, these frequencies can produce pitting. The ideal frequency is based on the material being cleaned, the size of the surface and the nature of the contamination.
2. Ultrasonic Cleaning Tank Size
The size of the cleaning system's container is critical because the parts to be cleaned must be immersed in the cleaning solution. For single-application ultrasonic cleaners, a customized container size appropriate for the specific part being cleaned is appropriate. For general purpose cleaners, the tank must fit the longest dimension of the largest part.
If many different parts are to be cleaned at the same time, a basket may be needed. Baskets keep small parts from clearing the bottom or sides of the tank, as vibration against the tank walls during cleaning may damage the parts. If a basket of sufficient size is used, the size of the cleaning tank must be able to accommodate the basket.
3. Ultrasonic Cleaning Power Supply
The ultrasonic cleaning system must produce enough ultrasonic waves to fill the cleaning tank. If the power is too low, it will produce dead spots and uneven cleaning. Turnkey systems automatically provide the correct power level for the ultrasonic cleaning system, but if the ultrasonic generator, transducer and cleaning tank are purchased separately, it is important to ensure that the power is high enough for effective cleaning.
For large tanks, several transducers may be required. A supplier of industrial ultrasonic cleaners can analyze the requirements and advise the customer on the appropriate power level. Both ultrasonic power ratings and multiple transducer configurations can affect cleaning performance, especially if the ultrasonic cleaner is added to an existing tank.
4. Cleaning with mild soaps and detergents
Industrial ultrasonic cleaners can be lightly cleaned with deionized water, but some heavier cleaning applications can benefit from the use of soap, detergent, or mild solvents. If a particular contaminant is difficult to clean, specific solvent contaminants will often speed up cleaning and improve cleaning performance. Mild soaps and detergents can help clean oily residues, but harsh chemicals are usually not used.
5, the use of heat to improve cleaning
Industrial ultrasonic cleaning machines can remove heavy contaminants consisting of hardened grease and carbon deposits, but the cleaning process may take more time. These types of deposits can be softened by heat, and soft substances are easier to remove. Heating the cleaning solution to just below the boiling point can speed up the cleaning of these applications and help ensure complete removal of the contamination.
If heat is to be used, the tank and ultrasonic transducer must be able to operate at temperatures below 100 degrees Fahrenheit. The tank must be equipped with a heater and the parts themselves must be able to withstand high temperatures.
