Daily Maintenance and Management of Agricultural Irrigation Systems

Daily Maintenance and Management of Agricultural Irrigation Systems

Ensuring the long-term reliability and efficient operation of agricultural irrigation systems is crucial, and this hinges on establishing and implementing a "preventive maintenance" daily management system. This is not a complex, high-tech task, but rather the standardization of regular inspection, cleaning, maintenance, and record-keeping into standard operating procedures. Good daily management can significantly extend equipment lifespan, prevent failures during critical irrigation periods, and ensure that every drop of water is used effectively.

The core of daily management lies in routine checks and operations before and after each irrigation cycle. Before starting the system, operators should spend a few minutes walking along the pipeline for a visual inspection: checking for obvious leaks at the pump and main pipe connections and valves; clearing weeds, leaves, and other debris around the pump inlet filter or foot valve to ensure unobstructed water intake; and checking whether sprinklers and drippers are blocked or covered with soil or crop residue. After starting, run the system briefly at low pressure to observe whether the sprinklers are working properly and rotating evenly, and listen for smooth pump operation. After irrigation, if the water source is turbid, it is recommended to run the pump with clean water for a few minutes to flush out any sediment that may have accumulated in the pump and pipes. Promptly drain any remaining water from the movable hoses in the field and coil them neatly, storing them in a cool place.

Regular, more comprehensive inspections and maintenance are a further step in management. Depending on the frequency of use, a systematic maintenance check should be performed every one or two weeks or monthly. Key aspects include: lubricating parts requiring lubrication, such as pump bearings, according to the instructions; checking and tightening all anchor bolts and pipe clamps; for sprinkler systems, removing several sprinklers to check for wear or blockage of internal filters and rotating parts, and cleaning or replacing them; for drip irrigation systems, checking each zone to ensure even water distribution from the drippers, and opening the flushing valve at the end of the lateral pipes to remove sediment. Also, check that all valves open and close smoothly and that there are no leaks.

Establishing records and seasonal maintenance completes the management cycle. Create a simple "Maintenance Log" for the entire system, clearly recording the date of each inspection, the problems found, and the corrective actions taken. This log serves as a valuable "health record" for the system, helping to identify patterns and predict potential problems. Before the end of the irrigation season and before the equipment is left idle for an extended period (especially during winter), thorough maintenance is essential: drain all accumulated water, completely empty the water from the pumps, pipes (especially the drain valves of buried pipes), and sprinklers to prevent freezing and cracking; clean the equipment and apply rust-preventive oil to exposed metal parts; and store movable parts in a dry and well-ventilated place. Through this complete management process, from daily routines to periodic maintenance, and from operation to record-keeping, your irrigation system will operate reliably year after year, providing a solid guarantee for agricultural production.
