Center-Pivot Sprinkler Irrigation Machine
Overview
Also known as a pointer sprinkler irrigation machine, the center-pivot end of this system is fixed, while the remaining truss structure rotates circularly around the fixed end, driven by a motor.
Irrigation water is drawn from the source, delivered through the interface at the center-pivot end to the truss’s water pipes, and then sprayed onto the field via nozzles for automatic irrigation. A key advantage is that a single water supply point can cover 200–2,000 mu (≈13.3–133.3 hectares), saving labor and water resources.
Truss designs vary to suit sprinklers of different lengths. The tower and center-pivot are engineered for durability, resisting damage from gravity or wind. This system is ideal for irrigating cash crops like grains, vegetables, and cotton.
Outstanding Advantages
- Standardized Design: Both the center pivot and truss follow standardized designs, ensuring rational structure and even force distribution.
- Low Maintenance: No corrosion-prone or easily damaged components exist, simplifying maintenance and extending service life.
- Corrosion & Strength Optimization: The water outlet uses unique fusion-welding, with connections inside the pipe—enhancing corrosion resistance and improving tensile/torsion strength.
- Reliable Electrical Connection: An external double-contact slip ring (high reliability) replaces wire-routing inside pipes and elbow-mounted slip rings, boosting safety.
- Slope Adaptability: Cross flexible joints between spans enable operation on slopes up to 30°. Aluminum alloy straight connectors link water pipes, with no exposed seals.
