Metal rocker arm spray guns, especially rocker arm nozzles, have a wide range of applications in sprinkler systems, and their main advantages can be summarized as follows:
Stable performance and wide applicability: The rocker arm nozzle is widely used in field irrigation, outdoor nurseries, fruit and vegetable gardens, and horticultural fields, and is one of the most widely used and stable nozzles.
Suitable for fixed, semi fixed, and mobile sprinkler systems, exhibiting stable operating characteristics at medium to long ranges.
Structural design and material advantages: Unique rocker arm design, including anti-wear sealing ring and H-shaped wear-resistant sealing gasket, can effectively prevent sand and dust from entering and excessive wear, thereby extending the lifespan of the nozzle.
Metal materials (such as all copper or zinc alloys) make it more durable and resistant to the corrosion of fertilizers and pesticides.
Flexible spraying mode: With a reversing mechanism, it can spray in a full circle or any sector shape, meeting the irrigation needs of different scenarios.
The low angle design of the side auxiliary nozzle can compensate for the distribution of water nearby, improve the uniformity coefficient of sprinkler irrigation, and ensure the uniformity of irrigation.
Working principle and performance: By utilizing the reaction force generated by the water flow impacting the guide vane at the front end of the vertical swing arm, the nozzle undergoes intermittent rotational motion. This working method is force balanced and reliable.
Compared with the horizontal rocker arm nozzle, the main advantage of the vertical rocker arm nozzle is that it has a better force situation, because the rocker arm does not directly impact the nozzle. During forward and reverse rotation, the force direction between the balance iron and the rocker arm axis is opposite, which can offset some of the impact force.
Energy saving and multifunctional development: Based on the rocker arm nozzle, energy-saving and windproof irregular nozzle nozzles, adjustable elevation angle and atomization degree nozzles, and non circular spray area nozzles can be further developed to meet more diversified irrigation needs.
Hydraulic performance parameters: The hydraulic performance parameters of the nozzle include flow rate, working pressure, range, as well as irrigation intensity, irrigation uniformity coefficient, atomization index, etc. These parameters can be designed and adjusted to meet specific irrigation needs.
In summary, the metal rocker arm spray gun has become an indispensable and important equipment in sprinkler systems due to its stable performance, flexible design, durable materials, and diverse functions.
