Impact Sprinkler Pattern Modification
نویسنده
چکیده
Methods of modifying the water distribution pattern of an impact-drive sprinkler are described. A method of pattern modification called intermittent diffusion is introduced. A deflector attached to the drive arm intermittently diffuses the jet of a standard circular-orifice nozzle, producing desirable pattern shapes while maintaining a large pattern radius. Uniformity of application for both wind and no-wind conditions was evaluated using both the deflector and diffuse type nozzles. The deflector is beneficial for low pressure sprinkling, particularly under windy conditions. Equations were developed to predict the operating characteristics of the impact arm.

Precipitation Evaluation of Round- and Square-patterned Impact Sprinklers
In the fall of 1999, two types of impact sprinklers were evaluated to determine the distribution of precipitation under normal operating conditions. The sprinkler types included a traditional round-patterned design (Rain Bird Maxi-Bird) and a recently developed sprinkler delivering water in a square pattern, called Square Shooter. The squarepatterned sprinkler was more precise in delivering a u...
متن کاملPerformance of an Agricultural Impact Sprinkler Fitted with Plastic Nozzles
The radial water distribution and irrigation performance of an agricultural sprinkler with plastic nozzles were analysed. Twenty-six tests with an isolated sprinkler corresponding to different combinations of three working pressure (p, 200, 300 and 400 kPa) and three nozzle diameters of the main nozzle (4.0, 4.5 and 5.0 mm) were performed to evaluate the radial water distribution curves, All th...
متن کاملSimulating water distribution patterns for fixed spray plate sprinkler using the ballistic theory
Ballistic simulation of the spray sprinkler for self-propelled irrigation machines requires the incorporation of the effect of the jet impact with the deflecting plate. The kinetic energy losses produced by the jet impact with the spray plate were experimentally characterized for different nozzle sizes and two working pressures for fixed spray plate sprinklers (FSPS). A technique of low speed p...

Performance based methodologies are becoming increasingly common in fire safety due to the inability of prescriptive codes to account for every architectural feature. Fire Sprinkler suppression systems have long been used to provide property protection and enhance life safety. However, very few methodologies exist to account for the impact of sprinkler sprays on fire scenarios. Current methods ...
