Working principle of ultrasound
Ultrasound waves are mechanical noise. Unlike the strict acoustic phenomena that characterize the ultrasonic frequencies are higher than average audible by a human ear. Conventionally used to discriminate the frequency sonic waves by ultrasonic waves is set at 20 kHz. The same term ultrasound clearly indicates what is beyond (ultra) sound, identifying only the physical phenomenon with sound audible.
Like any other type of ultrasound wave phenomenon is subject to phenomena of reflection, refraction and diffraction and can be defined by parameters such as frequency, wavelength, speed of propagation, the intensity (measured in decibels), l 'attenuation (due to acoustic impedance of the medium crossed).
The operating principle of ultrasound for cleaning and / or cleaning is the generation (Ultrasonic Generator) of high-frequency waves through transducer (piezoelectric) placed in a tank containing water and detergent.
The transducers are applied on the bottom or on the walls of the tank, they emit a vibration frequency of 27,000 Hz and beyond.
The propagation of waves in the liquid is uniform, investing suoerfice pieces to be treated, forming waves that implode and harm edecompressione compression pressure up to about 1000 bar through microbollicine (cavitation).
