How does the impact sprinkler achieve uniform watering through structure and operation? ​

What are the key structural components of the impact sprinkler? ​

The impact sprinkler can achieve uniform watering due to its carefully designed structure and the tacit cooperation between its components. It is mainly composed of the sprinkler body, impact arm, nozzle, spring, sleeve and other components, each of which plays an important role in the process of uniform watering. The sprinkler body is the basic framework of the entire equipment, carrying all other components and providing them with a stable installation and working platform. ​

What role does the nozzle play in the watering process? ​

The design of the nozzle is particularly critical. The flow channel inside it has been specially processed to convert the incoming water flow into a jet with a certain shape and speed. When water enters the sprinkler body through the water pipeline under a certain pressure and then sprays out from the nozzle, the high-speed jet formed will have a strong impact force on the impact block of the impact arm, which is an important first step in starting the sprinkler operation. ​

How does the swing and reset of the impact arm promote the watering process?​

The impact arm uses the shaft sleeve as a fulcrum. After being impacted by the jet, it will swing upward around the fulcrum and compress the spring to store energy. When the impact arm swings to a certain angle, the jet no longer impacts the impact block. At this time, the elastic force of the spring begins to play a role, driving the impact arm to quickly reset. At the moment when the impact arm resets, the paddle at its end will collide with the paddle pin on the nozzle body. The reaction force generated by this collision will push the nozzle body to rotate around its axis at a certain angle. ​

How does the rotation of the nozzle body achieve the coverage of the sprinkler range? ​

As the nozzle body rotates, the spray direction of the nozzle also changes, and the jet will hit the impact block of the impact arm again, repeating the above swing, reset, collision, and rotation process. In this way, the nozzle body rotates continuously, and the water flow ejected by the nozzle can cover every corner of the circular or fan-shaped area centered on the nozzle. ​

How to avoid blind areas in sprinkling to ensure uniformity? ​

The spray angle and range of the nozzle are precisely designed so that adjacent spray areas can overlap each other during the rotation of the nozzle, avoiding the occurrence of blind areas in sprinkling. Moreover, during the spraying process, the water flow will gradually disperse into fine water droplets due to the influence of air resistance and its own gravity, further improving the uniformity of water sprinkling. ​

How does the rotation speed of the impact sprinkler affect the uniformity of water sprinkling? ​

The impact sprinkler can usually also adjust the rotation speed of the sprinkler by adjusting the counterweight on the impact arm or changing the elastic force of the spring. The stability of the rotation speed directly affects the amount of water received per unit area. A reasonable rotation speed can ensure that each area can get sufficient and uniform water, thereby achieving an overall uniform watering effect. ​

The impact sprinkler realizes the function of uniform water sprinkling through the orderly operation of various components, including jet impact, impact arm swing and reset, sprinkler body rotation, and reasonable design of spray parameters. It is widely used in agricultural irrigation, landscaping and other fields. ​
