Tips for maintaining solar water pump irrigation systems

1. Equipment Layout and Startup

• Equipment layout:
  • Prepare a stable bracket and position the solar panel in a sunny and unobstructed place.
  • Connect the water pump to the solar panel and place the pump in its predetermined working position.
• Start the equipment:
  • Before starting, ensure the power switch is off.
  • When starting, turn on the power switch first and confirm that the rotation direction of the water pump is correct.

2. Daily Operation and Maintenance

• Adjust the speed: Adjust the water pump speed as per actual needs for the best pumping effect.
• Check the suction head: Regularly check if the suction head of the pump meets requirements during operation. Investigate and replace the pump if the head is insufficient.
• Clear blockages: Regularly check the water inlet and impeller and clean immediately if there's debris blocking.
• Operation inspection: Conduct comprehensive inspections of the pump's operation regularly to ensure it's in normal condition.
• Cleaning solar panels: Keep solar panels clean by cleaning them regularly to remove dust and dirt.
• Wire inspection: Regularly check the wires of the water pump for firm connection and absence of aging or damage.

3. Regular Maintenance

• Replace the sealing ring: Replace it regularly as it's crucial for the pump's sealing performance.
• Replace the bearing: Check and replace severely worn bearings regularly as wear affects running stability.
• Recheck the suction head: Confirm again during maintenance if the suction head meets requirements.
• Steering confirmation: Recheck the rotation direction of the pump after maintenance and restart when correct.
• Speed monitoring: Regularly check if the pump's speed is within the normal range for pumping efficiency.
• Bottom valve inspection: Regularly check the bottom valve's sealing to avoid failures due to rust etc.

4. Maintenance of Irrigation System

• Pipe flushing: Open valves of the irrigation group, start the pump, and flush the plots one by one to remove pipe dirt.
• Filtration system maintenance: For different filters, either run the backwashing program or check and replenish filter materials.
• Winter protection: When temperature is below 5 degrees Celsius in winter without heating, power off the pump, open the valve to relieve pipe water pressure, protect probes and drain remaining water in fertilizer machine pipeline.
• Valve inspection: Inspect and maintain field valves and keep manual switches open for unobstructed flow.
• Pipeline storage: Straighten and properly store drip irrigation pipelines, remove and dry ball valves and store them properly to prevent freezing and cracking.
