Consulting for a degassed fine bubble generation liquid circulation system.

The Ultrasonic System Research Institute is applying measurement, analysis, and evaluation techniques related to the propagation state of ultrasound to publish technology that relaxes the surface residual stress of ultrasonic transducers using ultrasound and fine bubbles. This technology for relaxing surface residual stress has made it possible to improve fatigue strength against metal fatigue. As a result, the effects on various components, including ultrasonic tanks, have been demonstrated.

The Ultrasonic System Research Institute provides consulting services for the manufacturing and development methods of the "Deaeration Fine Bubble (Microbubble) Generation Liquid Circulation Device," which can efficiently control ultrasonic waves. "Deaeration 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 gas to form. The above describes the state of the deaeration liquid circulation device. 3) When the concentration of dissolved gas decreases, the bubble size of the dissolved gas due to cavitation becomes smaller. 4) Through appropriate liquid circulation, fine bubbles (microbubbles) of less than 20μ are generated. The above describes the state of the deaeration microbubble generation liquid circulation device. 5) When ultrasonic waves are applied to the above-mentioned deaeration fine bubble (microbubble) generation liquid circulation device, the ultrasonic waves disperse and crush the fine bubbles (microbubbles). When measuring the fine bubbles (microbubbles), the distribution of ultra-fine bubbles exceeds that of fine bubbles. The above state indicates that ultrasonic waves can be stably controlled.

The Ultrasonic System Research Institute has developed a technology that applies the control of ultrasound and fine bubbles within a water tank to stimulate the surfaces of various materials and components with megahertz acoustic flow. In particular, the homogenization of surface residual stress has led to many achievements. << Deaeration Fine Bubble (Microbubble) Generation Liquid Circulation Device >> 1) By narrowing the suction side of the pump, cavitation is generated. 2) Bubbles of dissolved gas are produced due to cavitation.

The Ultrasonic System Research Institute has developed an effective stirring (emulsification, dispersion, grinding) technology utilizing the technique of controlling "nonlinear phenomena of ultrasound (acoustic flow)." This technology controls ultrasound (cavitation, acoustic flow) by utilizing (evaluating) the ultrasonic propagation characteristics (analysis results) of indirect containers through surface inspection, ultrasonic tanks, and other items. Furthermore, it realizes effective ultrasonic (cavitation, acoustic flow) propagation states tailored to the structure, material, and acoustic properties of specific target objects, achieved through the interaction of glass containers, ultrasound, and target objects, by controlling the oscillation of ultrasound. In particular, the dynamic characteristics of harmonics through acoustic flow control enable responses at the nano level. It has been applied and developed from examples of dispersing metal powders to nanosize. Through original measurement and analysis techniques of ultrasonic propagation states, we have confirmed the evaluation of acoustic flow and numerous know-how.
