High-Efficiency Energy-Saving Sprinkler Irrigation Collaborative Design Scheme

High-Efficiency Energy-Saving Sprinkler Irrigation Collaborative Design Scheme

I. Core Concept

Considering the pump, pipeline, sprinkler head, and control system as a whole, this scheme pursues optimal overall energy efficiency through a systems thinking approach, rather than focusing solely on individual components.

II. Pump Selection: Precise Matching

On-Demand Selection: Calculate flow rate and head based on the actual irrigation area and group irrigation plan to avoid excessive power consumption.

Zoning and Peak Shifting: Irrigate plots in groups to reduce the instantaneous load on the pump and save electricity.

Optimizing High-Efficiency Models: Select high-efficiency pumps (e.g., Level 1 efficiency) for longer-term energy savings.

III. Pipeline Design: Reducing Losses

Optimized Layout: Pipelines should be as straight and short as possible, minimizing unnecessary bends and lengths.

Scientific Piping: Main pipes should be sufficiently thick, with branch pipes matched progressively to ensure smooth water flow and balanced pressure.

Optimal Pipe Materials: Use pipes with smooth inner walls (e.g., PE pipes) to significantly reduce water flow resistance.

IV. Sprinkler Heads and Zoning: Intelligent Settings

Rational Zoning: Irrigation zones are divided according to crop water requirements, terrain elevation, or differences in sunlight to achieve on-demand water supply.

Selecting High-Efficiency Sprinkler Heads: Prioritize water-saving sprinklers that achieve good atomization and even distribution at low pressure.

Matching Spray Patterns: Select fan-shaped, rectangular, or other sprinklers based on planting ridge shape to reduce ineffective spraying.

V. Control System: Precise Water Saving

Basic Automatic Control: Employs timers and soil moisture sensors to avoid over-irrigation.

Advanced Intelligent Solution (Optional): Uses an IoT controller for remote start/stop, fault alarms, and data monitoring for more refined management.

VI. Installation and Commissioning: Ensuring High Efficiency

Standardized Installation: Ensure unobstructed air intake for the water pump and tight, leak-free pipe connections.

System Commissioning: A comprehensive commissioning process is essential. Adjust valves in each branch line to ensure uniform pressure and normal spraying at the end sprinklers.

VII. Maintenance Points: Maintaining Performance

Clean filters regularly to prevent clogging.

Drain pipes promptly in winter to prevent freezing and cracking.

Before each irrigation season, check sprinkler heads for blockages or damage and replace them promptly.

Key Summary: The key to high efficiency and energy saving lies in synergistic optimization. By precisely calculating and selecting water pumps, optimizing pipelines to reduce resistance, rationally zoning and matching sprinkler heads, and supplementing with automatic control, a tightly linked water-saving system is formed. Scientific initial design yields more significant and lasting energy savings than simply replacing equipment later.
