Ultrasonic technology

Ultrasonic liquid circulation technology: Degassing fine bubble generation liquid circulation device

(1) Generate cavitation by squeezing the suction of the pump.
(2) The cavitation creates bubbles from the resolved gas.
The above is the state of the degassing liquid circulation device.
(3) When the concentration of dissolved gas lowers, the bubble size of dissolved gas becomes smaller.
(4) Adequate liquid circulation generates fine bubbles of 20μ or less.
The above is the state of the degassing fine bubble generation liquid circulation device.
(5) When the above degassing fine bubble generating liquid circulation device is irradiated with ultrasonic waves, the ultrasonic waves disperse and crush fine bubbles. When fine bubbles are measured, you will see that the distribution amount of nanobubbles is larger than the distribution amount of fine bubbles.
The above is the state of ultrasonic sound that is stable and controllable.


About ultrasonic liquid circulation technology
(1) A dedicated ultrasonic water tank (original manufacturing method) is used.
(The material may be resin, stainless steel, or glass.)
(2) Water tank installation
a. Dedicated components are used
b. The natural vibration, ultrasonic frequency, and output are optimized.
(The response varies depending on the acoustic characteristics of the tank.)
(3) The ultrasonic transducer is installed with dedicated components.
(The dedicated components limit the use situation of the standing waves, cavitation, and acoustic streaming.)
(4) A degassing/fine bubble generator is used.
(The standard concentration level for dissolved oxygen 5-6mg /l)
(5) The surface of the water tank and the ultrasonic vibrator is modified.

The above settings and the diffusibility of the fine bubbles ensure that the cleaning solution has a uniform state.
Ultrasonic waves propagate in a uniform liquid, producing a stable ultrasonic state.


From this state, liquid circulation control is performed to achieve the desired ultrasonic effect (propagation state).
(Our know-how is about attaining a uniform sound pressure distribution throughout the water tank and control the operation of ultrasonic waves, deaerators, liquid circulation pumps, etc.)
The target ultrasonic state is confirmed by sound pressure measurement analysis (ultrasonic tester).

The point is to balance between proper ultrasonic waves (frequency and output) and liquid circulation.
You can control the state of acoustic flow and acceleration effect caused by ultrasound, by setting an appropriate flow amount and speed for the liquid circulation and ultrasonic wave cavitation.

It uses the propagation state of ultrasonic waves that spread evenly due to the effects of the fine bubbles.

Ultrasonic probe manufacturing technology

From the usage data of the original product, Ultrasonic Tester, our company has developed an ultrasonic probe manufacturing technology that takes account of acoustic characteristics.

It is a new technology for the development of ultrasonic probe development, allowing for the use of a suitable ultrasonic wave propagation state for a particular purpose (measurement, oscillation, control).

It is a new technology for the development of ultrasonic probe development, allowing for using a suitable ultrasonic wave propagation state for a particular purpose (measurement, oscillation, control). In particular, our original nonlinear resonance phenomenon* control technology —a technique that uses the response characteristics of the combination of oscillation and reception — has helped increase the application of ultrasonic waves in new ways.

* Original nonlinear resonance phenomenon: Resonance phenomenon of ultrasonic vibration, in which the original oscillation control realized higher harmonics.
