High pressure nozzle operation mode
The high-pressure nozzle relies on a plunger pump or a diaphragm pump to pressurize the liquid medicine to 0.5-2MPa, and sprays it out at high speed through a nozzle with a tiny aperture (0.3-1mm), forming a high-kinetic energy penetrating mist flow. Its core advantage lies in the efficient coverage of complex scenes.
The centrifugal nozzle generates centrifugal force through the high-speed rotating impeller, which throws out the liquid medicine and breaks it into uniform droplets. The core advantage lies in the precise and controllable atomization effect and the uniform droplet size (50-200μm). By adjusting the impeller speed (usually 3000-10000 rpm), the droplet size can be accurately controlled to avoid the uneven droplet problem caused by pressure fluctuations in traditional high-pressure nozzles.

Frequently Asked Questions
A1: Our agricultural drones utilize an RTK differential positioning system that achieves centimeter-level accuracy. This enables precise navigation and prevents missed or repeated spraying during crop protection operations.
A2: High-pressure nozzles pressurize liquid to form a penetrating mist flow ideal for complex crop canopies. Centrifugal nozzles use rotating force to create highly uniform, adjustable droplet sizes (50-200μm) to prevent drift.
A3: The drones are equipped with binocular visual obstacle avoidance radar. This system scans crop canopies and terrain in real-time, allowing the drone to maintain an optimal spraying distance of 0.8-1.2 meters while dodging obstacles.
A4: The AL4-22 drone features a 22L pesticide tank capacity and can cover between 9 to 12 hectares per hour, depending on the speed, wind conditions, and terrain layout.
A5: Yes, the AL4-22 model is designed to withstand wind speeds of up to 10 m/s, ensuring stable flight and consistent spraying performance even in moderately windy weather.
A6: The drone features an umbrella foldable structure. Its size is reduced from 2025*1970*690 mm in operation to just 860*730*690 mm when folded, making it highly convenient to transport to and from the fields.
