During the use of lawn metal nozzles, it is important to pay attention to key issues such as installation specifications, pressure control, regular maintenance, anti clogging treatment, and winter protection. Specific instructions are as follows:
1. Installation specifications
Installation location: Avoid objects such as trees and tall crops that may obstruct water flow, and ensure that there are no obstacles within the coverage area of the nozzle. For buried nozzles, the top of the nozzle should be level with the ground or slightly lower to prevent tripping pedestrians or damaging equipment. Installation angle: Adjust the spraying angle according to the actual terrain, such as setting it to 180 ° or 90 ° in corner areas, to ensure even irrigation.
Connection method: Use hinged joints (Qianqiu frame) to connect the nozzle and branch pipe, to prevent mechanical impact or human activities from damaging the pipeline or nozzle.
.II. Pressure Control
Working Pressure: The metal nozzle needs to operate within the rated working pressure range. If the pressure is too low, it will cause uneven spraying, and if the pressure is too high, it may damage the nozzle or increase the degree of atomization. Under the influence of wind, the shape of the spray distribution may be irregular.
. Pressure regulation: By adjusting the pump speed or valve opening, ensure stable working pressure of the nozzle. For large lawns, zoning irrigation can be used to balance the pressure demands of different areas.III. Regular Maintenance
Inspection cycle: In cold regions, check once a year before watering in spring.
; In areas with long irrigation periods or year-round irrigation, check at least twice a year.Inspection content:
Spray angle: Ensure the setting is correct and adjust according to the manufacturer's requirements.
.Rotation function: Check if the nozzle rotates normally and replace damaged parts in a timely manner.
.Sealing: Check if the sealing ring leaks water, and replace it if it is severely worn.
.Shell integrity: Check if the nozzle shell is broken and replace the damaged shell or the entire nozzle in a timely manner.
.Maintenance records: Establish maintenance files to record inspection time, content, and replaced parts for easy tracking of equipment status.
.4. Anti clogging treatment
Water source filtration: Install a filter screen to filter the water source and prevent impurities from entering the nozzle.
. For areas with poor water quality, it is necessary to increase the filtration system or regularly clean the filter screen.Nozzle cleaning: Regularly clean the grass leaves, roots, and other debris inside the nozzle to ensure smooth water flow.
. For severely clogged nozzles, they can be replaced with nozzles of the same model. Pipeline flushing: Before installation and after each use, flush the inside of the pipeline with clean water to prevent fertilizer crystallization or impurity accumulation.Fifth, Winter Protection
Drain accumulated water: When not in use in winter, drain the accumulated water in the nozzle and pipeline to prevent freezing and cracking.
.Anti freezing measures: In cold regions, insulation materials can be used to wrap the nozzle and pipeline, or anti freezing devices can be installed.
.6. Other precautions
Avoid stepping on: When trimming or maintaining the lawn, avoid stepping on the nozzle to prevent damage.
.Accessory replacement: Use original accessories for replacement to ensure equipment compatibility and performance.
.Intelligent upgrade: can be paired with weather stations or soil sensors to achieve on-demand irrigation and improve water resource utilization.
