Design and Installation of Ultra High-Speed Deluge Systems

摘要

The design and installation of ultra high-speed deluge system for ammunition applications involves a technology which is substantially different from that associated with automatic sprinkler systems. Because, due the speed of water delivery from all of the nozzles, ultra high-speed deluge systems are highly dependent on the detection system, piping network, nozzles, and water supply characteristics, the design and the installation of ultra high-speed deluge who thoroughly understand the limitations and capabilities of these systems. Ultra high-speed deluge systems are sometimes installed with no thought or knowledge as to the hazards that they are to protect. Often, the system is designed or procured around specifications written for a completely different process. The lack of a complete definition of response time also effects the design of ultra high-speed deluge system. This paper will discuss the following points: (a) Brief description of an ultra high speed deluge system; (b) Justification for ultra high-speed deluge systems; (c) Proposed change to the definition of response time; (d) Factors effecting water travel time from the nozzle to hazard; (e) Changes to deluge system regulation.
