1. What Are Spray Nozzles?
Definition and Working Principle of Spray Nozzles
А spray nozzle is a precision fluid-control device designed to convert liquid pressure into a controlled spray pattern.
By forcing liquid through a specially designed opening or internal flow passage, the nozzle controls how the fluid exits, determining critical characteristics such as:
- Хуткасць патоку
- Spray angle
- Droplet size
- Spray distribution
- Atomization efficiency
- Fluid velocity
The fundamental operating principle is based on the conversion of pressure energy into kinetic energy.
When liquid enters the nozzle under pressure, the internal geometry accelerates and redirects the fluid flow.
Depending on the nozzle design, the output can range from a concentrated jet stream to a fine mist containing extremely small droplets.
Напрыклад:
- А high-pressure cleaning nozzle focuses fluid energy into a narrow, high-velocity stream.
- А cooling nozzle produces a controlled spray pattern to maximize heat transfer.
- А таксама atomizing nozzle breaks liquid into fine droplets for combustion, слой, or humidification processes.
The performance of a spray nozzle depends not only on the external shape but also on the precision of internal features such as flow channels, swirl chambers, and orifice dimensions.
