What a Multi Ultrasonic Frequency Generator Does and the Benefits It Offers

October 27, 2016

What a Multi Ultrasonic Frequency Generator Does and the Benefits It OffersManufacturing companies often have a variety of cleaning needs for a wide range of items. They may have to clean parts and components during or at the end of the manufacturing process or they may have to regularly clean tools. Incoming parts may have to be cleaned before use or containers before and after being filled. Using traditional cleaning methods, many cleaning systems, chemicals and scrubbers might have to be stored and used.

With ultrasonic cleaning, most of these cleaning applications can be carried out with one ultrasonic system. Even if the applications require different cleaning intensities and the removal of different contaminants, a multi-frequency ultrasonic generator may be an effective and cost saving solution.

Multi-Frequency Ultrasonic Generators

Ultrasonic cleaning systems rely on sound waves that create bubbles in the cleaning solution. The ultrasonic sound waves are produced by an ultrasonic frequency generator linked to transducers submerged in the cleaning liquid. Different frequencies and powers deliver varying cleaning intensities. The higher the frequency, the gentler the cleaning action while higher power delivers more bubbles and greater cleaning power. For varied cleaning applications a generator that can produce different frequencies and deliver different power levels can represent an ideal cleaning solution.

Such a multi-frequency ultrasonic generator should be able to produce low frequencies around 30 kHz for intensive cleaning of robust parts at high power levels as well as frequencies over 100 kHz for more gentle cleaning of delicate parts. Transducer arrays must be able to handle the complete range of frequencies without major refit or set-up work. Such systems are flexible enough to handle various cleaning applications using the same equipment and cleaning set-up.

The Kaijo Quava Multi Ultrasonic Generator

Kaijo Corporation has developed a complete range of ultrasonic frequency generators covering almost all cleaning applications. The company offers both turnkey systems and individual components ranging in frequency from 19.5 kHz to 950 kHz. For cleaning applications that require multiple frequencies due to a variety of parts that have to be cleaned, Kaijo can supply the Quava Multi generator in two versions.

Each version can generate three frequencies, with the lower range model producing 26/78/130 kHz and the higher range model producing 38/100/160 kHz. The models have an eight-step power output with a maximum of 600 W and both models work with an array of transducers that can handle all three frequencies.

This means that the cleaning system can switch frequencies and adjust power output as required without having to change transducers or the ultrasonic generator set-up. Different types of parts and devices with different cleaning requirements and varying cleaning intensities can be cleaned by the same system. The Quava Multi generator is flexible enough for remote control operators to adjust the cleaning process as required.

The Quava Ultrasonic Frequency Generator Features

The Quava Multi generator is designed for multiple cleaning applications with easy changeover from one cleaning task to another. The generator has four selectable oscillation modes and automatic frequency tracking. It features Soft Start and Soft Stop functions that can be controlled via an RS 485 port and monitored with a 0 to 5 V output or a 4 to 20 ma signal. The power supply is 200 to 240 V single phase 50/60 Hz and the current at maximum power is 10 A. At installation or for the replacement of a transducer array or a generator, no field calibration is required.

Kaijo’s multi ultrasonic frequency generator is the ideal solution to varied cleaning requirements in a manufacturing environment with diverse cleaning needs. Kaijo has designed a cost-effective system that is built with high-quality components to deliver excellent reliability and performance.

How Kaijo’s Ultrasonic Cleaning Generator Improves the Manufacturing Process

May 26, 2016

How Kaijo's Ultrasonic Cleaning Generator Improves the Manufacturing ProcessUltrasonic cleaning generators produce an electrical signal that transducers change into ultrasonic waves in the cleaning liquid. The waves produce cavitation bubbles that appear and collapse in time with the frequency of the ultrasonic generator. The collapse of the bubbles results in a powerful scrubbing action that removes surface contaminants from the parts to be cleaned. Ultrasonic technology is clean, environmentally friendly and often works more quickly and more effectively than other cleaning technologies. Small and mid-sized manufacturing plants and shops can improve their manufacturing process by converting to ultrasonic cleaning, achieving improved cleaning performance at reduced cost.

Cleaning Without Chemicals

Where other technologies produce effective cleaning with harsh chemicals, ultrasonic technology cleans with bubble action using no chemicals or only a benign detergent solution. The liquid baths can go to boiling temperatures so chemical additives are often not needed. Ultrasonic cleaning generators such as the Kaijo Phenix Legend Series can produce a wide range of frequencies to match any cleaning application.

Robust items such as machined parts, glass and ceramics can be cleaned at lower frequencies that deliver large bubbles with high cleaning energies and intensive cleaning action. Kaijo Phenix Legend models producing 38 kHz and 78 kHz fall into this category. Frequencies such as the 100 kHz, 130 kHz or 160 kHz produced by the higher frequency Phenix Legend models produce smaller bubbles with less energy and can be used for more delicate cleaning tasks. Fragile electronic components are often cleaned at these frequencies.

Cleaning with ultrasonic generators can improve the manufacturing process itself and reduce costs. Cleaning with the appropriate frequency delivers exactly the type of cleaning action required for a particular application and makes cleaning more effective. The reduction or elimination of chemical use is itself a substantial cost saving, but additional savings result from the elimination of costs associated with the storage, handling, neutralization and disposal of such chemicals.

Cleaning Irregular Parts

Cleaning parts with cavities or irregular surfaces is sometimes challenging. Chemicals often diffuse slowly into holes and mechanical cleaning can’t easily reach into deep crevices. Ultrasonic cleaning generators produce sound waves that are distributed throughout the cleaning tank. In this way bubbles and cleaning action are created even in hard to reach places. Parts are cleaned evenly and thoroughly, leaving no residues and giving an improved cleaning result.

Using Kaijo’s Water Resonance System with an ultrasonic cleaning generator will significantly enhance the clean power by conditioning the water. The system promotes a more even distribution of bubbles for an effective cleaning power that can approach five times that of cleaning systems without water resonance.

Cleaning Quickly at the Right Power

Unlike other cleaning technologies, ultrasonic cleaning generators can accurately control the cleaning power they deliver. The correct frequency gives the appropriate cleaning intensity but the generator power gives the cleaning power delivered to the cleaning solution. When operated at the right frequency and power for the particular cleaning job, ultrasonic cleaning generators often deliver excellent cleaning in a short time. Even tough jobs can take about 20 minutes and light cleaning can be carried out very quickly.

Kaijo’s Phenix Legend Ultrasonic cleaning generator can reduce cleaning time, clean more effectively and reduce costs when compared to other cleaning solutions. Small and mid-size manufacturing operations can get better process results and save money at the same time.
