The Nozzle Design of Atomizing Micro Sprinklers

ON 02 . Oct . 2023

The nozzle design is a critical component of Atomizing Micro Sprinklers, playing a pivotal role in the creation and control of water droplets. The nozzle design is a fusion of art and science, where engineering principles and innovation come together to achieve the desired atomization effect.

The Importance of Nozzle Design

Nozzle design is crucial because it directly influences the size, distribution, and trajectory of water droplets. Atomizing micro sprinkler systems aim to produce fine mist-like droplets, which are essential for efficient and precise irrigation. The design of the nozzle determines how effectively this can be achieved.

Pressure Nozzles

Pressure nozzles are one of the most common types used in atomizing micro sprinkler systems. They operate based on the force generated by water pressure to break the water into smaller droplets. The key components of a pressure nozzle include:

Orifice: The orifice is a small opening through which water flows. Its diameter significantly affects droplet size. Smaller orifice sizes create finer droplets.

Swirl Chamber: Some pressure nozzles incorporate a swirl chamber that imparts rotational motion to the water stream, aiding in the breakup of larger droplets.

Diffuser: The diffuser section of the nozzle helps in reducing the water's velocity, further contributing to droplet formation.

Air-Assisted Nozzles

Air-assisted nozzles introduce compressed air into the water stream before it exits the nozzle. This added air turbulence enhances atomization, resulting in even finer droplets. The key components of air-assisted nozzles include:

Air Inlet: Compressed air is introduced through an air inlet, mixing with the water before exiting the nozzle.

Air/Water Mixing Chamber: This chamber allows for thorough mixing of air and water, creating the conditions for smaller droplets.

Nozzle Tip: The nozzle tip is where the atomized mixture of air and water exits the nozzle, forming the fine mist.

Turbulent Flow Nozzles

Turbulent flow nozzles are designed to induce turbulence within the water stream, further breaking down larger droplets into smaller ones. These nozzles typically have a more complex internal geometry compared to pressure nozzles. The key components include:

Turbulent Chamber: This section of the nozzle generates turbulence by creating intricate flow patterns within the water.

Exit Port: The exit port allows the water to exit the nozzle, now composed of smaller, atomized droplets.

Droplet Size Control

The ability to control droplet size is a crucial aspect of nozzle design in atomizing micro sprinklers. Various factors can be adjusted to achieve the desired droplet size, including:

Orifice Size: Smaller orifice sizes generally produce finer droplets, while larger orifices result in larger droplets.

Water Pressure: Altering the water pressure can affect droplet size. Lower pressure often leads to finer misting.

Flow Rate: Adjusting the flow rate of water through the nozzle can also impact droplet size. Lower flow rates can lead to finer droplets.

Single-nozzles Mist atomizing irrigation sprinkler

The Single-nozzles Uniform Coverage Atomizing Irrigation Sprinkler works by using a single nozzle to atomize water into a fine mist or spray, which is then distributed across the area being irrigated. By atomizing the water into small droplets, it reduces the amount of water that is lost to evaporation and wind drift. This means that less water is needed to achieve the same level of irrigation, which can result in significant water savings.
