Basic Contents and Steps of Daily Maintenance for Sprinkler Pumps

The core of daily maintenance for sprinkler pumps lies in proactively identifying and addressing minor issues through a series of regular and simple operations to prevent them from developing into major malfunctions, thereby ensuring their continuous and reliable operation throughout the irrigation season. This process is not complex, but it requires consistent effort and must be solidified into standard operating habits. Its basic content can be summarized as: regular inspection, operational observation, timely cleaning, and focused maintenance.

The first step in daily maintenance is the routine inspection and preparation before and after each pump start-up and shutdown. Before starting, spend a few minutes conducting a thorough inspection around the pump: check that all connections to the pump and inlet/outlet pipes are secure and free of leaks; clear weeds, leaves, and other debris from around the suction filter or foot valve to ensure unobstructed water intake; check the tension and wear of the belts (if belt-driven). For diesel pumps, also check that the engine oil and coolant levels are sufficient. After starting, allow the pump to run under low load for a short time, carefully listening to the sound of the motor (or diesel engine) and pump body to ensure it is smooth and even. Observe whether the readings of the pressure gauge and voltmeter are within the normal range.

Careful observation during operation and immediate cleaning after shutdown are key aspects of maintenance. During pump operation, pay attention to any abnormal noise, vibration, or localized overheating. After each irrigation operation, if the water source is turbid, it is recommended to run the pump briefly with clean water to flush away any sediment that may have accumulated inside. Afterward, turn off the power or shut off the engine, and wipe the water stains and mud off the outer surface of the pump body with a damp cloth, especially the motor heat sink area, keeping it dry and clean to facilitate heat dissipation. At the same time, check the shaft seal (where the pump shaft exits the pump casing) for any continuous, excessive leakage.

Performing more in-depth maintenance regularly and keeping records will elevate maintenance to a higher level. Depending on usage frequency, more comprehensive maintenance should be performed every one to two months or per irrigation season: Add or replace appropriate grease as required by the instruction manual for parts requiring lubrication, such as bearings; check and tighten all foundation bolts and connecting bolts; for pumps using mechanical seals, check for malfunctions; for older packing seals, adjust the gland nut appropriately (allowing a very small amount of water dripping out for lubrication). Maintain a simple maintenance log for each pump, recording the date of each inspection, operating hours, problems found, and corrective actions taken. Before long-term storage at the end of the irrigation season, be sure to drain any water from the pump casing and piping to prevent freezing and cracking in winter, and store the pump in a dry, well-ventilated place. This complete process, from daily inspections to regular maintenance, from cleaning to record keeping, is the most reliable investment to ensure the long-term, efficient operation of sprinkler pumps.
