Sprinkler Check and Maintenance

Increasing production efficiency is essential for producers to maintain or increase their economic return in an increasingly competitive global market. Irrigation scheduling, irrigation uniformity, and irrigation efficiency maximize production. Center pivot irrigation systems are capable of attaining uniformities and efficiencies of 90-95 percent with values of 85 percent generally considered the minimum acceptable level before maintenance is needed. There are a few simple checks an operator can perform to ensure they are getting the most out of their system.

  1. To Replace Old Technology for Better Irrigation Efficiency.
  2. Check Nozzles and Plates for Wear.
  3. Check Sprinkler Rotor Resistance
  4. Check Goose Necks, Hoses and Fittings for Leaks.
  5. Check Weights and Drops; Do They Hang Straight?
  6. Check Spacing.
  7. Check Regulators to make Sure They are Working Properly.

 A good strategy against worn nozzles and malfunctioning pressure regulators is to replace the sprinkler package every 5–8 years depending on water quality and hours of use. An accepted industry rule of thumb is to consider replacing sprinkler packages every 10,000 hours.

 A malfunctioning regulator can result in a sprinkler pressure that will be too high. A sprinkler emitting a fine spray or faster rotation speed relative to adjacent sprinklers may indicate a malfunctioning pressure regulator that is operating above its nominal rating. If a regulator is operating below its nominal rating, sprinklers will produce larger droplets and slower rotation speed.
