Here’s a complete explanation of the 1 to 1 Ducar 100 Raingun system, including its working principle, components, and installation process:
1. What is a 1 to 1 Ducar 100 Raingun System?
"1 to 1" means one raingun is connected to one water source (pump or valve) in a standalone system.
Ducar 100 is a high-volume turbo-driven raingun sprinkler used for irrigation in agriculture and horticulture.
2. Specifications of Ducar 100 Raingun:
Nozzle size: 20–32 mm (changeable)
Throw radius: 35–90 meters (depends on pressure & nozzle)
Pressure requirement: 4 – 8 kg/cm²
Discharge: 12,000 – 30,000 liters/hour
Rotation: Full circle or part circle
Drive: Gear/turbo drive (no electricity required)
3. Working System:
Water is pumped from a source (borewell, canal, etc.) using a high-pressure pump.
Water enters the raingun through the inlet pipe.
Internal turbine blades spin, transferring motion to the gear system, which rotates the gun.
The nozzle sprays water at high velocity, breaking into droplets that simulate natural rainfall.
The angle and arc can be adjusted to cover desired field areas (full circle or sector).
4. Components Needed for 1 to 1 System:
1. Ducar 100 Raingun
2. Heavy-duty stand/tripod
3. G.I. or HDPE pipe (63mm or 75mm)
4. Elbow, flanges, clamps, gaskets
5. Control valve or gate valve
6. High-pressure pump (7.5 HP to 15 HP)
7. Flexible hose or suction pipe (if mobile)
5. Installation Process:
Step-by-Step:
1. Select Location:
Place the raingun in the center of the area you want to irrigate.
Ensure there's no obstruction to the spray.
2. Fix the Stand:
Anchor the heavy-duty stand or tripod securely.
Mount the Ducar 100 Raingun on top.
3. Connect Inlet Pipe:
Use G.I. or HDPE pipe from pump to raingun.
Use clamps and gaskets for leak-free connection.
4. Attach Control Valve:
Install a gate valve before the raingun to control flow and pressure.
5. Setup Pump:
Connect the pump to your water source.
Ensure it provides sufficient pressure (minimum 4 kg/cm² for good performance).
