4. Setup and Installation
Follow these steps for proper installation of the centrifugal nozzle onto your agricultural drone or spraying system.
4.1 Mounting the Nozzle
The nozzle is designed for secure attachment to drone arms or mounting brackets. Refer to the diagram for mounting hole dimensions.
4.2 Electrical Wiring
Connect the nozzle to your drone's power and control system according to the wiring diagram provided. Ensure correct polarity and secure connections to prevent electrical issues.
- Red wire: Positive power (+)
- Blue wire: Ground (GND)
- Yellow wire: Signal (Sigle)
- Black wire: Negative power (-)
4.3 Liquid Pipe Connection
Connect the liquid supply pipe to the nozzle's inlet. Ensure the pipe caliber matches the nozzle's specifications (8mm or 12mm) and that the connection is leak-proof.
5. Operation
The 8820 MAX Centrifugal Nozzle operates using a PWM CAN control mode, allowing for stepless speed regulation and precise control over the spray output.
- Power On: Ensure the nozzle is securely mounted and wired, and the liquid supply is connected. Power on your drone or spraying system.
- Control Adjustment: Use your drone's flight controller or dedicated spraying system interface to adjust the PWM signal. This will control the nozzle's speed and, consequently, the spray flow rate and droplet size.
- Monitoring: Monitor the RPM feedback (PWM(N;CAM(Y) if your system supports it) to ensure consistent operation.
- Spraying: Begin spraying operations, adjusting the nozzle's output as needed for the specific application and crop type.
- Power Off: After use, turn off the liquid supply, then power off the nozzle and drone system.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your centrifugal nozzle.
- Cleaning: After each use, especially when spraying corrosive chemicals, flush the nozzle with clean water to prevent clogging and corrosion.
- Inspection: Periodically inspect the nozzle for any signs of wear, damage, or blockages. Check electrical connections for corrosion or looseness.
- Storage: Store the nozzle in a clean, dry place away from direct sunlight and extreme temperatures.
- Winterization: If operating in cold climates, ensure all liquid is drained from the nozzle and pipes to prevent freezing damage.
7. Troubleshooting
If you encounter issues with your 8820 MAX Centrifugal Nozzle, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No spray output | Clogged nozzle, no liquid supply, power issue | Clean nozzle, check liquid tank and pump, verify power connections. |
| Inconsistent spray pattern | Partial clog, uneven liquid pressure | Clean nozzle thoroughly, check pump and liquid lines for blockages or leaks. |
| Nozzle not spinning | No power, faulty wiring, motor issue | Check power supply and wiring (Red+, Black-), ensure signal (Yellow) is present. If issues persist, contact support. |
| Leakage | Loose pipe connection, damaged seal | Tighten pipe connections, inspect and replace seals if necessary. |
8. User Tips
- For optimal spray coverage, calibrate the nozzle's flow rate and drone speed according to the specific chemical and crop requirements.
- Regularly check the battery voltage (12S-18S compatible) to ensure stable power delivery to the nozzle, especially during extended operations.
- Consider using a filter in your liquid supply line to prevent small particles from clogging the nozzle.
