Fire Hydrant & Sprinkler System
Fire Hydrant & Sprinkler System
A proper Hydrant System ensures an adequate, uninterrupted water supply, under sufficient pressure, at all strategic points of a building/factory in such a way that the fire is attacked immediately, with minimum loss of time and with maximum efficiency. Automatic Fire Sprinklers are an essential element of Fire Protection as it is designed to both detect & extinguish fire. A properly designed and maintained automatic fire sprinkler system can significantly reduce property damage as well as protect lives.
Fire Hydrant System
The Fire Hydrant Line is always kept pressurized with water. In the event of any minor pressure drop in the system, the pressure reaches the preset pressure setting for Jockey pump, the Jockey pump will start automatically to compensate the pressure differential. In the event of opening one or more hydrant valve for fighting fire the Jockey pump will not be able to make up this water loss resulting in further pressure drop. When the falling pressure reaches the Preset pressure for main pump, the main pump will start automatically. In case of electric supply failure, stand by diesel engine driven pump will come into operation.
Sprinkler system
An automatic sprinkler system is intended to detect, control and extinguish a fire, and warn the occupants of occurrence of fire. The installation comprises fire pumps, water storage tanks, control valve sets, sprinkler heads, flow switches, pressure switches, pipe work and valves. The system operates automatically without human intervention.
Each sprinkler head contains a glass bulb or a fusible link. The bulb contains a liquid and a quantity of vapour. The liquid expands under the influence of heat as do the fusible link heads. When the temperature reaches a certain level – typically at 68 Degree Centigrade – it will expand the liquid and break the bulb or fusible link, which in turn releases water directly onto the seat of the fire.
