The role of the multi-frequency ultrasonic generator


Manufacturers usually have various cleaning needs for a wide range of items. They may need to clean parts and components during or at the end of the manufacturing process. In addition, they may need to clean their manufacturing tools and equipment regularly. Parts need to be cleaned before use or containers need to be cleaned before and after filling. Using traditional cleaning methods, many cleaning systems, chemicals, and scrubbers must be used and stored.

With ultrasonic cleaning, most cleaning applications can be done with an ultrasonic system. Multi-frequency ultrasonic generators may be an effective and cost-effective solution even if applications require different cleaning intensities and the removal of different contaminants.

Multi-frequency ultrasonic generator

Ultrasonic cleaning machines rely on sound waves to create bubbles in the cleaning fluid. The ultrasonic wave is generated by an ultrasonic frequency generator which is connected to a transducer immersed in a cleaning fluid. Different frequencies and powers provide different cleaning intensities. The higher the frequency, the gentler the cleaning action, and the greater the power, the more bubbles, and the greater the cleaning force. Generators that produce different frequencies and provide different power levels are ideal cleaning solutions for a variety of cleaning applications.

Such a multi-frequency ultrasonic generator shall be capable of producing low frequencies of approximately 30 kHz for intensive cleaning of solid parts at high power levels and at frequencies above 100 kHz, more gentle cleaning of precision parts. The transducer array must be able to handle a complete range of frequencies without major modifications or setup work. The system is flexible enough to handle a variety of cleaning applications using the same equipment and cleaning devices.

The ultrasonic generator of the blue whale

The blue whale has developed a full range of ultrasonic frequency generators for almost all cleaning applications. The company offers turnkey systems and individual components in the frequency range of 19.5 kHz to 950 kHz. Different versions of the generator are available for cleaning applications that require multiple frequencies for different components. Each version can produce three frequencies, 26/78/130 kHz for the low-frequency model and 38/100/160 kHz for the high-frequency model. These models have an eight-stage power output with a maximum power of 600W. Both models are used in conjunction with transducer arrays that can accommodate all three frequencies.

This means that the system can switch frequencies and adjust the power output without having to change the transducer or ultrasonic generator settings. Different types of parts and equipment with different cleaning requirements and intensities can be cleaned through the same system. The self-developed generator is flexible enough that a remote-controlled operator can adjust the cleaning process as needed.

The role of the multi-frequency ultrasonic generator

The multi-frequency ultrasonic generator is designed for a variety of cleaning applications and can be easily converted from one cleaning task to another. The generator has four optional oscillation modes and automatic frequency tracking. It has soft-start and soft-stop functions, and can be controlled through the RS 485 port, and through 0 to 5V output or 4 to 20 ma signal for monitoring. Power supply for 200 to 240 V single-phase 50/60 Hz, the maximum power current of 10 A. No on-site calibration is required during installation or when the transducer array or generator is replaced. In addition, cost-effective systems with high-quality components that provide excellent reliability and performance are ideal solutions to various cleaning requirements in a manufacturing environment that meets a wide range of cleaning needs.
