Hydraulic Spray Nozzles

Hydraulic spray nozzles use only liquid pressure to produce atomized droplets and are classified into Flat Spray, Cone Spray and Solid Stream Nozzles by spray patterns. A standard pressure is defined as the design pressure based on the usual liquid pressure in common use. The nozzles are designed to provide the specified spray angle, spray capacity, optimum spray pattern and spray distribution at each standard pressure.

Nozzle Characteristics

  • Spray Pattern: the spray pattern means the cross sectional shape of the spray: solid stream, flat spray, hollow cone spray, full cone spray.

  • Spray Capacity: the spray capacity increases as the specific gravity of the liquid to be sprayed becomes lighter and the spray pressure becomes higher

  • Spray Angle: the spray angle is measured at the top of the spray made by straight lines extending along the outer edges of the spray.

  • Spray Distribution: the spray distribution means the spray flow distribution in the direction of spray width ; ring-shaped distribution, mountain-shaped distribution, even spray distribution.

  • Spray Droplet Diameter: mean droplet diameter, which is an important element in selecting nozzles and designing nozzle-related equipment, varies depending on the type of the spray nozzles, liquid pressure and spray capacity.

  • Other Elements: With or without streaking, spray impact, spray droplet diameter, wear resistance, chemical resistance, heat resistance, pressure resistance, viscosity
