(1) After shutting down, the water and oil on the pump and pipeline should be wiped off in time to keep the unit clean.
(2) Regularly replace the bearing lubricant. For a new water pump equipped with a sliding bearing, the lubricating oil should be replaced when it is running for about 100 hours, and it should be replaced every 300-500 hours thereafter, but it should be replaced at least once every six months; For water pumps with rolling shafts, grease should be added every 1200-1500 hours of operation, but should be replaced at least once a year. Note that the water pump with a lower speed can appropriately prolong the time for changing or adding lubricant.
(3) If the water pump is not used for a long time or in winter, the water in the water pump and water pipes should be drained to prevent rust or cracking.
(4) After the drainage and irrigation season is over, it should be repaired once; and when the cumulative operation is about 2000 hours, it should be repaired once.
