→Installation and Usage Instructions for the Sprinkler System
The biggest challenge facing agriculture is irrigation—agricultural land is often vast, making it particularly difficult to evenly apply pesticides and water to crops. Fortunately, the development of agricultural machinery like sprinkler systems and sprayers has effectively addressed this issue.
A sprinkler system features a rotating platform supported by upright posts mounted on a wheeled frame. A water supply hose is coiled around the platform, with one end securely fastened to the reel and connected via a flexible pipe to a hollow shaft inside the platform. The other end of the hose links to a spray gun through a rigid pipe attached to the gun’s carriage. Meanwhile, the outlet of a water turbine installed on the central post connects directly to the hollow shaft at the platform’s axis. The turbine is equipped with an inlet pipe connection, and its output shaft drives a driven pulley on the gearbox via a belt. Finally, the driven sprocket on the gearbox’s output shaft meshes with a gear ring fixed to the rotating platform.
This sprinkler system utilizes a V-belt drive system, requiring the power unit’s main shaft and the pump to be aligned parallelly. The pulleys must be precisely aligned, with their center distance no less than twice the sum of their diameters. When connecting the pump to the power unit, ensure they share a common base and use a claw-type flexible coupling. Additionally, pay close attention to maintaining proper concentricity between the power unit’s main shaft and the pump’s shaft.
The pump should be installed at a height that is 1–2 meters lower than the allowable suction vacuum height, measured from the water surface in the intake tank. Ensure the ground beneath the pump installation area is firm and stable to prevent collapse or sinking into the soil.
When installing the water inlet pipeline, take extra care to prevent air leaks. The filter screen must be fully submerged in water, positioned about 30 cm below the water surface, while maintaining a safe distance from both the tank bottom and walls to avoid drawing in sediment, debris, or air.
During the installation of the water delivery hoses, avoid friction against sharp objects like stones or tree bark, and steer clear of areas where they might get crushed by vehicle wheels or trampled by pedestrians. Never allow the hoses to come into contact with moving machine parts. When transporting hoses, roll them neatly into coils rather than dragging them on the ground. For rigid pipes, disassemble them into individual sections before handling; never attempt to move multiple sections together, as this could lead to wear, damage to the pipes, or failure of the fittings. Also, protect the pipes from direct sunlight and rain to prevent plastic degradation or aging.
Before setting up the spray boom, position it horizontally on the ground, ensuring the boom joint faces are perfectly level for smooth rotation of the spray nozzles. Once properly aligned, secure the boom firmly in place. Attach the spray nozzles to the boom, checking that each nozzle rotates freely. Adjust the tension of the rocker arms to ensure optimal operation, and lubricate all moving parts with a small amount of oil. Finally, clean and securely connect the quick-connect fittings.
Before starting the pump, verify that the pump shaft rotates smoothly and in the correct direction without any signs of jamming, unusual noises, or other abnormalities.
For centrifugal pumps, always fill the pump casing completely with water prior to startup. Only after the entire water supply line and pump body are thoroughly primed can the pump be activated.

→Watertube Industries: Quick Facts About Drip Irrigation Tape
Drip irrigation is a precision irrigation method that uses a low-pressure pipeline system to deliver water directly to the field. Water is then distributed evenly and slowly—drop by drop—into the soil near the crop roots via emitters, such as drippers, orifices, or drip tapes installed along the lateral lines. This ensures that the soil in the area where the crop’s root system is most active remains consistently at an optimal moisture level, promoting ideal conditions for soil water, nutrients, air, temperature, and microbial activity. Ultimately, this creates favorable circumstances for achieving high and stable crop yields.
