A metal swing arm sprinkler head is a device that uses liquid to spray into mist in the air to moisten and irrigate plants or soil. Its main characteristics can be summarized as follows:
1、 Widely applicable scenarios
Metal swing arm sprinkler heads are widely used in field irrigation, outdoor nurseries, fruit and vegetable gardens, and horticultural fields, and are one of the most widely used nozzles.
2、 Stable performance
Structural design: Metal swing arm sprinkler heads typically adopt a unique swing arm design, which is not only aesthetically pleasing but also practical. For example, some nozzles are equipped with anti-wear seals and H-type wear-resistant gaskets, which can effectively prevent sand and dust from entering the nozzle interior and prevent excessive wear, thereby extending the service life of the nozzle.
Material advantage: Metal materials (such as all copper or zinc alloy) make the nozzle more durable and more resistant to corrosion from fertilizers and pesticides. In addition, the design of the protective cover also plays a role in preventing rust and corrosion inside the nozzle, further extending the lifespan of the nozzle.
3、 Flexible spraying mode
Reversing mechanism: The metal arm sprinkler head has a reversing mechanism that can achieve full circle or arbitrary fan-shaped spraying, meeting the irrigation needs of different scenarios.
Side sub nozzle: Some nozzles adopt a low angle design for their side sub nozzles, which can compensate for the problem of insufficient water distribution nearby, improve the uniformity coefficient of sprinkler irrigation, and ensure the uniformity of irrigation.
4、 Efficient working principle
The working principle of metal swing arm sprinkler nozzle is to use the reaction force generated by the water flow hitting the guide at the front end of the vertical swing arm to make the nozzle rotate intermittently. This working method is characterized by balanced stress and reliable work balance. Compared with the horizontal rocker arm nozzle, the main advantage of the vertical rocker arm nozzle is better force distribution, because the rocker arm does not directly impact the nozzle, and the direction of the force between the balance iron and the swing arm shaft is opposite during forward and reverse rotation, which can offset some of the impact force.
5、 Diversified functions
On the basis of metal rocker arm nozzles, energy-saving and windproof shaped nozzles, adjustable elevation angle and atomization degree nozzles, and non-circular spray area nozzles can be further developed to meet more diverse irrigation needs.
6、 Adjustable hydraulic performance parameters
The hydraulic performance parameters of metal swing arm sprinkler heads include flow rate, working pressure, range, as well as sprinkler intensity, sprinkler uniformity coefficient, atomization index, etc. These parameters can be designed and adjusted to meet specific irrigation needs.
In summary, metal swing arm sprinkler heads play an important role in agricultural irrigation due to their wide range of application scenarios, stable performance, flexible spraying modes, efficient working principles, diverse functions, and adjustable hydraulic performance parameters.
