SRM Nozzle Performance Data
The SRM nozzle performance data is presented in the table below:
Nozzle| Pressure (bar)| Pressure (kPa)| Radius (m)| Flow| Precipitation
(mm/hr)
---|---|---|---|---|---
Dk. Green| 1.7| 170| 4.3| 0.13| 14
Notes :
All precipitation rates are calculated for 180-degree operation. For the precipitation rate for a 360-degree sprinkler, divide by 2.
Product Usage Instructions
Installation
To install the SRM, follow these steps:
- Select a suitable location for the SRM.
- Ensure the water supply is turned off.
- Dig a hole in the ground that is large enough to accommodate the SRM.
- Place the SRM in the hole, ensuring it is level.
- Connect the water supply pipe to the SRM.
- Turn on the water supply and check for any leaks.
- Adjust the rotation and spray range as needed.
Adjustment
To adjust the rotation and spray range of the SRM, follow these steps:
- Locate the adjustment screw on the top of the SRM.
- Using a screwdriver, turn the adjustment screw clockwise to decrease the spray range or counterclockwise to increase the spray range.
- Observe the changes in the spray pattern and adjust as needed.
Maintenance
To ensure proper functioning of the SRM, regular maintenance is recommended:
- Inspect the SRM for any damage or clogs.
- Clean any debris or dirt that may have accumulated on the nozzle or rotor.
- Check for any leaks or water pressure issues.
- Replace any worn-out or damaged parts as needed.
Frequently Asked Questions (FAQ)
- Q: Can I install multiple SRMs in my irrigation system?
- A: Yes, you can install multiple SRMs in your irrigation system. Simply follow the installation instructions for each SRM and ensure proper spacing between them for optimal coverage.
- Q: Can I use the SRM with a water source that has low pressure?
- A: The SRM is designed to work with a wide range of water pressures. However, it is recommended to check the product specifications to ensure compatibility with your specific water pressure conditions.
- Q: How do I determine the precipitation rate for a 360-degree operation?
- A: To determine the precipitation rate for a 360-degree operation, divide the given precipitation rate by 2.
