Cavitation and acoustic flow of ultrasonic phenomena

A megahertz ultrasonic oscillation control probe that enables the utilization of ultrasonic propagation conditions from 1 to 900 MHz.

The Ultrasonic System Research Institute has developed a megahertz ultrasonic oscillation control probe that enables the utilization of ultrasonic propagation states from 1 to 900 MHz by combining it with a function generator for controlling ultrasonic propagation states. This is a new application technology based on measurement, analysis, and evaluation techniques of ultrasonic propagation states for precision cleaning, processing, stirring, and inspection. By utilizing the acoustic properties (surface elastic waves) of various materials, ultrasonic stimulation can be controlled for structures and machine tools weighing several tons, even in a 3000-liter water tank, with ultrasonic output below 20W. It was developed as an application method for nonlinear phenomena through an engineering (experimental and technical) perspective on elastic waves and an abstract algebraic ultrasonic model. The key point is the technology for utilizing surface elastic waves on the surface of ultrasonic elements. By confirming the propagation characteristics of ultrasonic waves depending on the conditions of the target object, it is important to address it as an original nonlinear resonance phenomenon. Note 1: Propagation characteristics of ultrasonic waves include nonlinear characteristics, response characteristics, fluctuation characteristics, and effects due to interactions.

Ultrasonic cleaning system that achieves ultrasonic control tailored to the purpose.

This is an effective device using a dedicated ultrasonic tank (original manufacturing method). Due to the high efficiency of ultrasonic utilization, standard tanks lack sufficient strength and durability. Depending on the target and purpose, multiple ultrasonic waves and a degassing fine bubble generation liquid circulation device are controlled based on sound pressure measurement analysis for cleaning, stirring, and surface modification. We propose various combinations and usage (control) methods. The key point is to achieve an ultrasonic propagation state tailored to the target, focusing on the "dissolved oxygen concentration distribution" and "liquid circulation" within the dedicated tank. << Degassing Fine Bubble (Microbubble) Generation Liquid Circulation Device >> 1) By narrowing the suction side of the pump, cavitation is generated. 2) Cavitation causes bubbles of dissolved gases to form. The above describes the state of the degassing liquid circulation device. 3) As the concentration of dissolved gases decreases, the bubble size of dissolved gases due to cavitation becomes smaller. 4) Through appropriate liquid circulation, fine bubbles (microbubbles) smaller than 20μ are generated. The above describes the state of the degassing microbubble generation liquid circulation device.

High Strength, Low Cost: The Economic Advantages of Carbon Steel Frames Carbon steel is inherently strong, and this high structural strength ensures stable wind resistance while allowing for a simple support structure, reducing the need for extra components. This also lowers the wear rate during transportation, enabling further savings in material costs and installation expenses. Transportation and Construction: Streamlining the Entire Project The advantages of carbon steel frames are also evident in the transportation and construction phases. Standardized designs simplify on-site installation and shorten construction periods. For example, carbon steel frames can be packaged using a combination of wooden sticks and iron ties, improving unloading efficiency and increasing transport volume. This reduces construction time and labor costs, distributing the overall burden of the project across all stages. Technological Innovation: Breakthroughs in Corrosion Resistance With the evolution of material technology, the corrosion treatment of carbon steel frames has also significantly advanced. Grace Solar has adapted to the technological trends in process development, and all current carbon steel frames utilize AlMgZn coating. At the same time, to meet the special requirements of each project, our company offers custom options for hot-dip galvanizing.
