Deluge Water Spray Sprinkler System
Deluge Systems, as
the name implies, deliver large quantities of water over
specific areas in a relatively short period of time. These
systems are used to protect against rapidly growing and
spreading fires, typically involving flameless liquids, solvents
etc.
Deluge Water spray systems are similar to automatic sprinkler
system except all nozzles are open and will discharge together
when control valve opens. These systems are designed to protect
areas where fire is likely to spread rapidly and / or where
cooling of surrounding equipment is necessary.
Deluge Waterspray Systems are similar to sprinkler systems in
that they control a water supply. Control valves, piping,
hangers, and discharge devices.
As such, these systems also require the same inspection,
testing, and maintenance as sprinkler system. However, water
spray systems can have, in addition to these items, a detection
systems that is hydraulic, pneumatic, or electrical, other
devices such as pipeline strainers (not normally found on
sprinkler systems), and devices required special attention in
order to maintain the operation status of the water spray
system.
Water spray systems are designed to direct water at a required
density, from nozzles having predetermined patterns to
completely impinge water onto the hazard surface being
protected. They are designed for use in a variety of special
hazards applications including flammable and combustible liquid
hazards, transformers and turbines.
In some circumstances extinguishment is not always desirable,
only cooling. Common applications include power generation
equipment (e.g. switchgear), flammable liquid storage, gas tanks
and process plants.
Cooling is achieved by the use of medium velocity spray nozzles
and extinguishment is usually by high velocity nozzles.
This system can be activated manually or automatically by
hydraulic, pneumatic or electrical detection systems.
This type of system also needs sufficient water flow and
pressure to contain or extinguish the type of hazards they are
there to protect.
