The key considerations and features of the nozzle design of atomizing micro sprinklers

ON 24 . Jul . 2023

The nozzle design is a critical aspect of atomizing micro sprinklers as it directly influences the formation of fine water droplets, creating the mist-like spray that characterizes these innovative irrigation tools. The engineering behind the nozzle design aims to achieve precise water atomization, uniform distribution, and efficient water use.

Atomization Mechanism:

The primary function of the nozzle is to break the incoming water flow into small droplets, resembling a mist. To achieve atomization, the nozzle utilizes various methods, including centrifugal force, hydraulic pressure, and air-assisted mechanisms. The specific technique employed depends on the type of micro sprinkler and the manufacturer's design.

Orifice Size and Shape:

The size and shape of the orifice, the small opening through which water passes, significantly influence droplet size and distribution. Smaller orifice sizes generally produce finer droplets, while larger orifices produce coarser droplets. The shape of the orifice can also impact the spray pattern. Common shapes include circular, rectangular, or slotted orifices.

Material and Durability:

The nozzle is often exposed to challenging environmental conditions, such as UV radiation, varying temperatures, and potential physical damage. As a result, nozzle materials need to be robust and durable. Stainless steel and hard plastics are commonly used due to their corrosion resistance and ability to withstand wear and tear.

Anti-Clogging Features:

Clogging can be a significant issue in irrigation systems, especially in areas with high sediment or debris content in the water supply. To address this, many atomizing micro sprinkler nozzles incorporate anti-clogging features, such as self-cleaning mechanisms, filters, and wider orifice openings. These features prevent the accumulation of particles that could obstruct water flow and affect droplet size.

HIGHLY EFFICIENT COOLING AND HUMIDIFICATION: Reduce temperatures by up to 5 degrees across your greenhouse or net house with perfectly uniform distribution of micro-sized droplets

LOW PRESSURE REQUIREMENTS: Get great performance and fine droplets of 65 microns at relatively low pressure of 4.0 bar.

AVOID PLANT DANAGE: “Bridge” free design and integral anti-drain valve prevents plant-damaging drip-off.

SUITABLE FOR PULSE ACTIVATION: Anti-drain valve ensures system is always full and ready, allowing high-frequency operation in short pulses.
