After starting the pump, if no water is produced for 3 minutes, check the system for any shutdown issues. If any abnormal conditions occur during operation—such as unusual noise, vibration, or water leakage—the pump should be stopped immediately. Monitor the bearing temperature closely, ensuring it does not exceed 75°C.
Check that the nozzle is functioning properly, with no irregular rotation, excessive speed, or complete stoppage. Ensure the steering mechanism moves smoothly without any issues.
Avoid using sprinkler irrigation when there is a high level of sediment in the water, as this can cause rapid wear on the pump impeller and sprinkler nozzles, potentially affecting crop growth.
To adapt to different soil types and crops, nozzles may need to be replaced. Adjusting the rotation speed can be done by tightening or loosening the rocker springs. The rocker arm is mounted on the rocker shaft and can be rotated to control the water spray depth and adjust the nozzle speed. Changing the reversal position can also affect the speed of the rotation.
A properly adjusted nozzle should operate at a slow speed to avoid surface runoff. Typically, small nozzles complete one full cycle every 1 to 2 minutes, medium nozzles take 3 to 4 minutes per cycle, and sprinklers rotate once every 5 to 7 minutes.
**Maintenance:**
Regularly check and tighten any loose components. Ensure all lubrication points are properly oiled to maintain smooth operation. Follow the manufacturer's guidelines for maintenance of the power unit and water pump.
If the irrigation system will be idle for an extended period, drain the pump completely. Disassemble the pump and sprinkler, clean them thoroughly, apply oil, and reassemble. Store all parts in a dry, protected area. Wash and dry the pipes, and coil the hoses neatly, placing them in a cool, dry location. Avoid storing these components in areas with high humidity, extreme temperatures, or exposure to acids and alkalis.
Lubricate the threads on the frame or quick connectors, especially in areas prone to rust, to prevent corrosion and ensure long-term performance.
