Ultrasonic Atomization Nozzle Operating Principle

Ultrasonic nozzles operate by converting a high frequency electrical signal, fed into two electrodes sandwiched between two piezoelectric transducers, resulting in mechanical expansion and contraction of the transducers. This causes vibrations to be sent down the nozzle’s titanium horn, ultrasonically vibrating at the nozzle’s atomizing tip. Liquid traveling down the center of the nozzle forms capillary waves as a result of this vibrational energy. As the liquid emerges onto the atomizing surface, it reaches a critical wave amplitude and is broken into a spray of tiny drops by the ultrasonic energy concentrated there. This ultrasonic nozzle design provides an easily controllable atomized spray that does not clog because of the large liquid feed orifice and the self-cleaning ultrasonic vibration.
