Center Pivot Irrigation System Maintenance

Center pivot irrigation system is designed and managed to apply water as uniformly as possible to enhance the crop production. Because of the highly automation, it's now the most popular irrigation method for the field crops irrigation.

For the users of the center pivot irrigation system, the regular maintenance work is key to ensuring stable operation of the equipment, including:

• Pivot Point: At start of irrigation season, grease pivot bearings. Repeat every 400 hours of operation.
• Gearboxes: At start of irrigation season, drain all gearboxes and refill with recommended oil.
• Center Drives: At start of irrigation season drain any water that may have accumulated during the irrigation season and fill to the proper level with the proper lubricant.
• Tires: Check tire inflation (use low pressure tire gauge). If tire pressure is too low the tires will lose the bead and damage the tube.
• Structure: Routinely check pivot, span and tower structures for loose or missing bolts.
• Connectors: Check for leaking gaskets, boots, drains, and malfunctioning sprinklers or pressure regulators.
• Electrical: Check pivot control panel and tower boxes starters for burned or pitted contacts.

Check all wire connections, particularly on starters, to ensure they are tight. Check safety limit switches in the intermediate tower control boxes. Check function of automatic switching devices such as auto-reverse, auto-stop and end gun (lube as required). Check tower box cam and bushings. Turn the cam back and forth several times to ensure there is no binding. 

During the above process, farmers always meet problems of some parts such as nozzles, sprinklers, pressure regulators, drop hoses, gearboxes, tires, electrical components, etc. RainTek can provide one-stop product supply for the pivot irrigation equipment users.
