Studies on Sprinklers Arrangement in Sprinkler Systems
Applied Mechanics and Materials, 2013To improve the fire suppressing efficiency and reliability of the sprinkler systems, in this paper we analysis and discuss a problem about sprinklers arrangement. Use the water distribution curve of ZST-15 and the MATLAB to accomplish a 3D surface fitting among radius of protection, working pressure and mounting height as well as get a function ...

2012 5th International Symposium on Communications, Control and Signal Processing, 2012
The following describes an application model of a robotic fire guard, an automated fire extinguishing system for detection and localized handling of potential outbreaks using an Infra-Red (IR) camera and a turret mounted dispenser. The acquired IR image is processed and the sources of heat isolated, the turret is successively aimed towards the fire by ...

Studies on Water Distribution Characteristics of Sprinkler in Sprinkler Systems
2015 Sixth International Conference on Intelligent Systems Design and Engineering Applications (ISDEA), 2015Sprinkling density is a major parameter of fire control capability in sprinkler system. In this paper, some experiments on sprinkler system involving its water distribution characteristics are carried out and discussed. We take the ZST-15 drop sprinkler as an example, the water distribution characteristics of building sprinkler which working pressure ...

The invention relates to a sprinkler device comprising a sprinkler head that can be pivoted about a pivoting axis in relation to a fixed base. The pivoting motion of said sprinkler head is driven by a turbine (TU), which is powered by water flowing through the latter by means of several individual nozzles (DKR, OKL), said turbine having in particular a
