The metal arm spray gun for farmland is a commonly used equipment in farmland irrigation systems, which achieves uniform irrigation through the rotation and spraying of the nozzle. Here is the correct usage method:
1、 Preparation before use
inspect equipment
Ensure that all components of the spray gun (such as the rocker arm, nozzle, bearings, etc.) are not damaged or loose, and that the nozzle is not blocked.
Check if the water pipe connection is secure and there is no leakage.
Confirm that the rotating mechanism of the spray gun (such as bearings and gears) is well lubricated and free of jamming.
Adjust spraying parameters
Adjust the spray angle of the spray gun according to the terrain of the farmland and crop needs (usually adjustable from 0 ° to 360 °).
Select the appropriate nozzle model (such as fan-shaped or circular nozzle) based on the water source pressure and spraying range.
Adjust the elevation angle of the spray gun (usually 15 ° -45 °) to control the spraying radius and uniformity.
2、 Operation steps
Startup and Debugging
Slowly open the water source valve to avoid equipment damage caused by sudden pressure changes.
Observe whether the spray gun rotates smoothly and whether the spraying is uniform. If any abnormalities occur (such as uneven spraying or rotation lag), immediately stop the machine for inspection.
Operation Monitoring
Regularly check the working status of the spray gun during operation to ensure no water leakage or abnormal noise.
Pay attention to whether the spraying range covers the target area, and adjust the position or parameters of the spray gun if necessary.
Shutdown and maintenance
Close the water source valve before stopping the machine, and then cut off the power after the spray gun stops rotating.
Clean the debris on the nozzle and rotating mechanism to prevent blockage or wear.
3、 Precautions
safe operation
Wear protective equipment during operation to avoid injury from high-pressure water flow or splashing liquids.
Do not touch rotating parts while the spray gun is running.
environmental adaptation
Adjust the spraying time according to the season and crop needs (such as avoiding high temperature periods).
When encountering strong winds or rainy weather, use should be suspended to prevent uneven spraying or equipment damage.
Regular maintenance
Check the lubrication of bearings and gears once a month and replenish lubricating oil in a timely manner.
Clean the nozzle and filter once a quarter to prevent clogging.
