What is the ultrasonic spray nozzle?

An ultrasonic spray nozzle is a device that uses ultrasonic vibrations to create a fine mist or spray of liquid. It consists of a piezoelectric transducer that converts electrical energy into mechanical vibrations. These vibrations are then transferred to a liquid, typically through a nozzle or atomizing plate, causing the liquid to break up into small droplets. Ultrasonic nozzles are a type of spray nozzle that use high frequency vibrations produced by piezoelectric transducers acting upon the nozzle tip that create capillary waves in a liquid film. Once the amplitude of the capillary waves reaches a critical height (due to the power level supplied by the generator), they become too tall to support themselves and tiny droplets fall off the tip of each wave resulting in atomization.The primary factors influencing the initial droplet size produced are frequency of vibration, surface tension, and viscosity of the liquid. Frequencies are commonly in the range of 20–180 kHz, beyond the range of human hearing, where the highest frequencies produce the smallest drop size.

What is the Advtanges of ultrasonic spray nozzle?

Ultrasonic spray nozzles have several advantages over traditional spray nozzles. They can produce a more uniform spray pattern with smaller droplet sizes, which can be beneficial for applications such as coating, painting, humidification, and cooling. The smaller droplet sizes also enable better surface coverage and improved penetration into porous materials.

Additionally, ultrasonic spray nozzles are often more efficient in their use of liquid compared to conventional nozzles, as they require lower liquid flow rates to achieve the desired spray coverage. This can result in cost savings and reduced waste.

Overall, ultrasonic spray nozzles offer precise and efficient spray control, making them suitable for various industrial, medical, and research applications.

How Ultrasonics Spray Nozzles Work?

Ultrasonic spray nozzles are constructed to vibrate longitudinally at high frequency by means of piezoelectric transducers. This longitudinal up and down motion creates standing waves in a thin film of applied liquid on the ultrasonic nozzle tip, in which the amplitude of these waves can be controlled by the power generator. These standing liquid waves can be extended upwards off the ultrasonic nozzle tip to the point they separate into evenly sized droplets with little to no kinetic energy (see video). Secondary shaping gas or ambient air can be used to easily entrain droplets to the desired shape and velocity if needed. A variety of ultrasonic nozzles are offered that help determine droplet size, liquid flow rate and spray patterns.
