Before and after the irrigation season, do a simple "physical examination" and maintenance for the water pump

The water pump is the core power for farmland irrigation. After a long period of work, or before a new round of busy work begins, it is crucial to conduct a systematic "physical examination" and maintenance for it. This can not only detect hidden dangers in time, but also significantly extend the life of equipment and ensure a smooth and efficient irrigation season. You can easily do this by following the steps below.

1. After the irrigation season: maintenance and storage to prepare for "rest"

After the use season is over, proper final care can prevent equipment damage during periods of inactivity.

Completely drain the water (the most critical step to prevent freezing):

After turning off the water source, be sure to open the drain plug at the bottom of the pump body and the lowest part of the pipe, and completely drain all the water in the pump and pipes. Especially for centrifugal pumps and self-priming pumps installed on the ground, the residual water freezing in winter will cause the pump casing and pipes to swell and crack.

Cleaning and drying:

Remove mud, weeds and insects from the surface of the pump body and the cooling grille. Clean the suction inlet filter.

Store the water pump in a dry, ventilated room or under a shed, away from rain and sunlight.

Key checks:

Check the seal: Check the shaft seal (pump shaft) for obvious signs of leakage.

Rotation inspection: After the power is turned off, manually rotate the pump shaft or fan to see if it feels smooth and whether there is any jamming or abnormal noise.

Electrical part: Coil the cables and check for damage. It is best to store electrical parts such as controllers and starters separately.

2. Before the irrigation season: start inspection and lay the foundation for "going out"

Before the start of a new season, careful inspection can avoid "unfavorable start".

Environment and installation checks:

Clean the debris at the installation location and ensure good ventilation and heat dissipation.

Retighten anchor bolts and all pipe connections to prevent loosening due to vibration during operation.

Mechanical condition review:

Lubrication: According to the instructions, add appropriate grease or oil to the designated bearing or oil hole.

Seals and gaskets: Check and replace obviously aged and deformed seals and gaskets.

Belts (if applicable): Check belt tightness and wear and adjust or replace if necessary.

Electrical safety confirmation:

Check whether the cables are aged or broken, and whether the connectors are firm and free of rust.

Before closing, use a test pen or multimeter to confirm that the power supply voltage is normal (especially three-phase power to prevent phase loss).

3. Trial operation and dynamic "physical examination"

After completing the static inspection and maintenance, conduct a trial run, which is the most important "physical examination" link.

Water filling and exhausting: For pumps that need to be filled with water, ensure that the pump chamber is filled with water and the air is exhausted.

Start-up observation: Turn on the power for a short time and observe whether the steering is correct (for newly installed or repaired pumps) and whether the start-up is brisk and powerful.

"Three checks" during operation:

Check the sound: Listen to see if the running sound is smooth and even, without friction, impact or other abnormal noise.

Check the vibration: touch the pump body and feel whether the vibration is slight and steady.

Check the water output: Observe whether the water output and pressure are normal and stable, and whether there is any leakage in the pipeline.

Pay attention to the temperature rise: after running for a period of time, touch the motor housing lightly with the back of your hand (be careful of burns). It should feel warm but not hot. Abnormally high temperatures require immediate shutdown and inspection.

4. Maintenance and recording tips

Create a simple file: Prepare a small book to record the date of each maintenance, parts replaced and problems found.

Prepare commonly used wearing parts: such as sealing rings, belts, fuses, etc., in case of emergency.

Clarify the boundaries of capabilities: For complex problems found (such as internal abnormal noise, bearing damage, serious decline in motor performance), do not force use or disassemble by yourself, and contact professionals for maintenance in time.

In summary, maintenance before and after the irrigation season is like regular maintenance on a car. Proper "settlement" after the season can prevent problems before they occur; careful "awakening" before the season can ensure a good start. By insisting on doing these five things: "empty, clean, inspect, lubricate, and test run", your water pump will reliably accompany you every harvest season year after year. Remember, every bit of care you put into your equipment will pay off in steady water flow and efficient irrigation.
