Easy to operate Ultrasonic Washing Line
The Ultrasonic Washing Line has a good cleaning effect and is easy to operate. The sound that people hear is a signal with a frequency of 20-20000 Hz. The sound wave higher than 20000 Hz is called Ultrasonic Washing Line. The transmission of sound waves is transmitted in the longitudinal direction of the sinusoid. Many small bubbles occur. One reason is that the inner part of the liquid exhibits tensile stress. The negative pressure is formed, and the pressure drop causes the gas which is originally dissolved in the liquid to be supersaturated, and escapes from the liquid to become small bubbles; the other reason is that the strong tensile stress "pulls" the liquid into a hollow, called cavitation.
Ultrasonic waves are sound waves with a frequency higher than 20,000 Hz. They have good directionality, strong penetrating ability, easy to obtain more concentrated sound energy, and can be used in distance measurement, speed measurement, cleaning, welding, crushing, and extinction. Bactericidal disinfection, etc. There are many uses in medicine, military, industry, and agriculture. Ultrasound is named because its lower frequency limit is approximately equal to the upper limit of human hearing.
The principle of Ultrasonic Washing Line is mainly through the transducer, which converts the sound energy of the power ultrasonic frequency source into mechanical oscillation, and the ultrasonic wave is radiated into the cleaning liquid in the tank through the cleaning tank wall. Because of the radiation of the ultrasonic waves, the microbubbles in the liquid in the tank can be oscillated by the action of the sound waves.
When the sound pressure or sound intensity is reached by a certain degree of pressure, the bubble will swell and then suddenly close. During this process, the shock wave occurs at the moment when the bubble is closed, so that the pressure of 1012-1013pa and the local temperature adjustment occur around the bubble. The huge pressure generated by the ultrasonic cavitation can damage the insoluble dirt and cause them to decompose into the solution. The direct repeated impact of steam-type cavitation on dirt.
