What are the reasons for the "atomization" or fine water mist in Pop - up sprinklers?

Reasons for the generation of atomization or fine water mist
1. Excessive system water pressure
When the water supply pressure of the irrigation system exceeds the rated working pressure designed for the sprinkler, the water flow is forcibly dispersed into fine water mist under high - pressure conditions, resulting in a distorted spraying effect.
2. Nozzle blockage or wear
The nozzle is a key component for controlling the water flow pattern. If the nozzle is blocked by impurities such as sediment and scale, or it is worn and deformed after long - term use, the water flow passage will narrow, and the local pressure will rise sharply, thus causing the atomization phenomenon.
3. Failure of the internal rotating mechanism
Pop - up Sprinklers rely on internal gears or transmission structures to achieve rotary spraying. If the rotating mechanism is worn, stuck, or fails, the sprinkler cannot rotate normally, and the water flow will continuously impact the same position, forming local fine water mist.
4. Filter screen blockage
The filter screen at the water inlet is used to filter impurities. If the filter screen is blocked, the poor water inflow will lead to abnormal pressure inside the sprinkler, which will also cause the water flow to atomize.
5. Improper installation or debugging
If the installation height of the sprinkler is too low, the angle is deviated, or the pressure parameters are set incorrectly during debugging, the normal spraying pattern of the water flow will be disrupted, resulting in atomization.
6. Water quality issues
When using irrigation water containing a large amount of suspended impurities (such as sediment and algae), the impurities are likely to adhere to the nozzle or filter screen, indirectly causing blockage or abnormal pressure, and ultimately leading to the appearance of fine water mist.

Solutions and maintenance suggestions
1. Pressure monitoring and adjustment
Regularly check the water supply pressure of the system to ensure that it operates within the rated working range of the sprinkler; install a pressure - reducing valve or pressure - regulating device if necessary.
2. Regular cleaning and replacement of components
Periodically clean key components such as nozzles and filter screens, and promptly replace worn or damaged parts to prevent atomization caused by blockage.
3. Inspection of the rotating mechanism
Lubricate and maintain rotating parts such as gears and drive shafts to ensure that the sprinkler can rotate smoothly and avoid local atomization caused by mechanism failures.
4. Optimize installation and debugging
According to the product technical manual, reasonably set the burial depth, installation angle, and spraying radius of the sprinkler to ensure uniform water flow coverage.
5. Improve water quality
If necessary, additional filtration or sedimentation devices can be installed before water supply to reduce the content of suspended particles in the water and reduce secondary pollution to the sprinkler.
