The main function of an impact sprinkler is to provide a reliable and efficient method for evenly distributing water over large areas. They are very common tools in horticulture, agriculture, and landscape irrigation.
This is the primary task of the impact sprinkler. They are designed to project a stream of water outwards, covering a large circular or fan-shaped area, ensuring that the entire irrigated area receives sufficient water.
Due to their simple mechanical impact principle, impact sprinklers are robust and can operate reliably under various water quality conditions (including water containing small impurities), requiring minimal maintenance.
They typically produce larger water droplets, which makes the water stream less susceptible to being blown away by wind compared to fine mist, helping to maintain the water's range and intended coverage pattern.
Agricultural Irrigation: They are an economical and effective choice for irrigating large areas of crops.
Lawns and Pastures: Ensuring sufficient water for large lawns, parks, or pastures.
Fire Suppression and Cooling: In industrial or special environments, they are sometimes used for dust suppression or pre-wetting and cooling equipment.
The unique aspect of the impact sprinkler lies in its movement:
A high-speed stream of water is ejected from the nozzle.
The water stream strikes a small component called the "impact arm" or "reaction arm." This impact arm is quickly pushed away from the nozzle, simultaneously striking a small tooth or notch below the arm.
After being pushed away, the impact arm quickly springs back to its original position, ready to receive the next impact from the water stream.
Each "impact-reset" cycle gives the sprinkler body a small thrust, causing it to rotate a small step in a preset direction. This process repeats continuously, allowing the impact sprinkler to rotate slowly and regularly, achieving comprehensive and even water coverage of the surrounding area.
