Automatic Ultrasonic Spraying Machine

Unlike traditional atomizing nozzles, Ultrasonic atomizing nozzle only uses ultrasonic vibration energy for atomization. Ultrasonic spraying machine is regarded as a "green" technology because of its low energy consumption and high efficiency. It is an ideal choice for key fluid applications.

The ultrasonic spray system, also called ultrasonic nebulizer or ultrasonic spray nozzle, can produce very fine droplets through ultrasonic vibration. It is also known as "dry fog". In the ultrasonic spraying process, the droplet size and distribution can be accurately controlled, so that very small droplets and particles can evaporate rapidly, resulting in particles with high specific surface area.

Droplet size

The droplet size mainly depends on the ultrasonic frequency. The higher the frequency, the smaller the droplet size. The median droplet size at 20kHz is 90 microns, and at 50KHz, the droplet size is further reduced to an average of 30 microns.

Atomization flow

The flow range of ultrasonic nozzle is generally large. Unlike the traditional air driven nozzle, ultrasonic nozzle does not rely on the force of air to decompose the liquid flow for atomization. Therefore, the amount of liquid atomized by the nozzle per unit time of the same solution is mainly controlled by the liquid conveying system combined with the nozzle.

Liquid delivery pump: ultrasonic nozzle can be used with various liquid delivery systems, such as syringe pump, gear pump, peristaltic pump, pressure tank, etc. No matter which system is used, any of these systems will work as long as the liquid is transported at a stable flow within the working range of the nozzle. However, pulsation should be avoided, even instantaneous pulses may cause the liquid to fall out of the operating range. This is particularly evident for low flow applications such as stent coatings.

Guide device: since droplets usually drift downward under the action of gravity, when installing the atomizing head, the atomizing head * should face downward to reduce the interference of air. If directional focusing is required to achieve the desired coating effect, an air baffle can be used to guide the air flow（ Under some conditions, the ultrasonic nozzle can be said to be an airless system. The air supply system is usually used to form the atomization plume and provide direction and force. In this case, air is used as an auxiliary.)
