Multi-Tank Ultrasonic Cleaning System Design
Learn how multi-tank ultrasonic cleaning improves process separation, rinsing, filtration, circulation, and drying to maintain stable industrial cleaning quality.
What Is a Multi-Tank Ultrasonic Cleaning System?
Why is a “multi-tank” system needed instead of a single tank?
Purpose of multiple tanks:
1. Process separation
2. Prevention of cross-contamination
3. Quality improvement
Multi-tank systems are widely used in industries such as hardware, optoelectronics, semiconductors, molds, and precision machining.
How to Plan a Multi-Tank Cleaning Process?
1. Ultrasonic Rough Cleaning Tank
2. Ultrasonic Precision Cleaning Tank
3. Overflow Rinse Tank
4. Pure Water Rinse Tank
5. Air Blow-Off
6. Drying Tank
Why use two ultrasonic tanks?
Answer:
“Pre-cleaning for heavy contamination → Precision cleaning for fine contamination” can avoid using high frequency in the beginning and still failing to clean thoroughly. It also prevents low-frequency cleaning from damaging sensitive parts.
Why use pure water at the end?
Answer:
Pure water contains no impurities, ions, or sprayed contaminants, which helps prevent water spots after drying.
Equipment Requires Filtration, Circulation, and Oil-Water Separation
In a multi-tank ultrasonic cleaning system, filtration, circulation, and oil-water separation are essential core functions.
If any of these three functions are missing, even with strong ultrasonic power, problems such as increasingly dirty liquid, uneven cleaning, and surface fogging may occur.
1. Filtration System: Maintains Cleaning Solution Cleanliness
• Impurities, metal particles, and dust in the cleaning solution will reattach to the workpiece if they are not filtered.
• Long-term unfiltered operation reduces ultrasonic cavitation performance.
2. Liquid Circulation: Prevents Sedimentation and Energy Dead Zones
• Keeps the cleaning solution flowing and prevents contaminants from accumulating at the tank bottom.
• Flow direction can carry away detached contaminants and prevent reattachment.
• Helps improve cleaning uniformity.
• Improves long-term equipment operation stability and service life.
3. Oil-Water Separation: Prevents Oil from Reattaching
• Machining oil may adhere to the surface of parts again, causing oxidation, film adhesion, or staining after cleaning.
• If oil is dispersed on the liquid surface, the workpiece may pass through the oil layer when removed, resulting in an oily surface or incomplete cleaning.
• Oil-water separation can extend filter life and improve cleaning quality.
A multi-tank ultrasonic cleaning system is not simply about having more tanks. It is an integrated process of “process configuration + energy matching.”
Through the correct combination of frequency, power, rinsing, pure water, and drying systems, cross-contamination can be avoided and each batch can maintain consistent quality.
YONG JI Enterprise can customize multi-tank ultrasonic cleaning systems according to workpiece material, contamination type, and line layout, creating an efficient, stable, and reliable cleaning process to improve production quality and efficiency.
