Sprinkler Systems: Common Malfunctions and Troubleshooting Tips
2021-02-02
Sprinkler irrigation machine It is essential equipment for irrigation in various settings, not only boosting efficiency but also helping conserve water. As a result, more and more people are choosing irrigation machines for their watering tasks. Of course, even a high-quality irrigation machine may encounter some issues after prolonged use. Here are the common malfunctions when using sprinklers—and their corresponding solutions.
1. Sprinkler irrigation machine Water supply is insufficient.
The reason is Clogged water intake filters or self-priming pump impellers in the sprinkler truck; elevator speeds that are too high or too low, as well as leaks around the sprayer impeller seals. Clogs in the filter or impeller should be cleared; lift should be reduced or speed increased; and the seals on the spray ring should be replaced.
2. Sprinkler irrigation machine Water pipe leak
The reason is The sealing element of the sprinkler quick-connect fitting is severely worn or cracked, and the contact surface of the fitting is contaminated with dirt. Any dirt on the contact surface should be replaced or removed.
3. Irrigation nozzle fails to rotate
The reasons are: improper installation angle of the sprinkler arm’s rocker arm, coupled with insufficient attention to this issue; loose rocker arms or springs that are too tightly compressed; blockages in the flow path or inadequate water pressure; and excessively small clearance between the hollow shaft and sleeve components of the sprinkler mechanism. To resolve these issues, adjust the relative positioning of the deflector plate and the centerline of the water flow direction; fine-tune the rocker arm adjustment mechanism and its associated screws; tighten the retaining plate screws or reposition the rocker arm spring to achieve the desired angle; clear any obstructions in the flow channels, or optimize the working environment pressure; and finally, either polish the hollow shaft and sleeve surfaces or replace the hollow shaft with a new sleeve assembly.
4. Sprinkler irrigation machine Nozzle instability
The reasons include: improper installation of the sprinkler arm, incorrect spring adjustment, and loose rocker shaft; failure of the sprinkler’s reversing mechanism or severe wear on the rocker shaft; and the reversing mechanism being set too low, resulting in excessive friction.
5. The sprayer nozzle has a small spraying range and produces uneven coverage.
The reasons are: the sprinkler rocker arm is set to an excessively high ball-impact frequency; the rocker arm height has been incorrectly developed; the pressure cannot be too low; and the flow channels are blocked. To address these issues, adjust the rocker arm spring, as well as the adjustments and screws, and modify the water intake design depth of one of the rocker arms. Additionally, calibrate the working environment pressure and remove any blockages in the flow channels.
When using drip irrigation, do not use saline solution for irrigation, and avoid applying it in areas where adequate flushing conditions are unavailable. Or use it year-round, otherwise the drip irrigation effect will be compromised.
