Best tips for maintaining solar water pump irrigation systems

1. Equipment layout and startup

    ● Equipment layout: Prepare a stable bracket and properly arrange the solar panel in a sunny and unobstructed position. Then, connect the water pump to the solar panel and place it in the predetermined working position.

    ● Start the equipment: Before starting, make sure the power switch is off. When starting, first turn on the power switch and confirm that the rotation direction of the water pump is correct.

2. Daily operation and maintenance

    ● Adjust the speed: According to actual needs, adjust the speed of the water pump in time to achieve the best pumping effect.

    ● Check the suction head: During the operation of the equipment, regularly check whether the suction head of the water pump meets the requirements. If the head is found to be insufficient, the cause should be promptly investigated and the water pump should be replaced if necessary.

    ● Clear blockages: Regularly check the water inlet and impeller to ensure that there is no debris blocking. Once a blockage is found, it should be cleaned immediately.

    ● Operation inspection: Regularly conduct a comprehensive inspection of the operation of the water pump to ensure that it is in normal condition.

    ● Cleaning solar panels: Keeping solar panels clean is essential for their efficient operation. Therefore, it needs to be cleaned regularly to remove dust, dirt and other impurities.

    ● Wire inspection: Check the wires of the water pump regularly to ensure that the wires are firmly connected and there is no aging or damage.

3. Regular maintenance

    ● Replace the sealing ring: The sealing ring is a key component of the sealing performance of the water pump and needs to be replaced regularly to ensure its sealing effect.

    ● Replace the bearing: The wear of the bearing will affect the running stability of the water pump, so it is necessary to regularly check and replace the severely worn bearings.

    ● Recheck the suction head: During the maintenance process, it is necessary to confirm again whether the suction head of the water pump meets the requirements to avoid problems caused by insufficient head.

    ● Steering confirmation: After each maintenance, it is necessary to recheck whether the rotation direction of the water pump is correct and restart it after ensuring that it is correct.

    ● Speed monitoring: Regularly check whether the speed of the water pump is within the normal range to ensure its pumping efficiency.

    ● Bottom valve inspection: The sealing performance of the bottom valve has an important impact on the normal operation of the water pump. Therefore, it is necessary to regularly check the sealing of the bottom valve to avoid sealing failure caused by rust and other reasons.

4. Maintenance of irrigation system

    ● Pipe flushing: Open several valves of the irrigation group, start the water pump, flush the irrigation plots one by one, and remove the dirt in the pipe.

    ● Filtration system maintenance: For automatic backwashing laminated filters, turn on the water pump to run the backwashing program; for medium filters, check whether the sand and gravel filter materials are sufficient and replenish them in time.

    ● Winter protection: When the temperature is below 5 degrees Celsius in winter and there is no heating facility, make sure that the water pump is powered off and open the valve to remove the water pressure in the pipe. At the same time, protect the EC/PH probe and drain the remaining water in the fertilizer machine pipeline.

    ● Valve inspection: Field valves should also be inspected and maintained, and the manual switches of each valve should be placed in the open position to ensure unobstructed flow.

    ● Pipeline storage: Drip irrigation pipelines should be straightened and properly stored to prevent twisting. The ball valve should be removed and dried and placed in the warehouse or placed in a half-open position to prevent freezing and cracking.

In summary, by following these maintenance tips, you can ensure the long-term stable operation of the solar water pump irrigation system, improve pumping efficiency, reduce failure rate, and provide a stable and reliable water source guarantee for agricultural production.
