The technical requirements for water sprinkler systems mainly include the following aspects:
Working pressure and flow requirements: The working pressure of the water sprinkler system should ensure stable operation under the maximum operating pressure. The working pressure of the system should be determined according to the maximum operating pressure during water supply, and ensure that the pressure at zero flow of the fire pump does not exceed 140% of the design working pressure.
Design and installation requirements for sprinkler heads: The model, specification and nominal operating temperature of the sprinkler heads should meet the design requirements. The sprinklers should be installed firmly and neatly, without obvious bumps and deformations, and the surface coating or plating should be complete. The installation spacing and location of the sprinklers and the distance between the splash plate and the surrounding obstacles such as the top plate or beam should meet the design requirements.
System function requirements: The water sprinkler system should be set in automatic control to ensure that it can be started in time when a fire occurs. The system should include components such as alarm valve groups and water flow indicators. These components should be sensitive and reliable and be able to provide correct feedback signals when started.
Material and quality requirements: The materials of the sprinkler system should comply with the requirements of national and local fire protection regulations and have the characteristics of corrosion resistance, high temperature resistance, and pressure resistance. The sprinkler head should be made of stainless steel or copper, the pipe should be made of steel pipe or copper pipe, and the pipe connector should be made of cast iron or steel.
Debugging and maintenance requirements: System debugging should ensure that all parts are coordinated and meet the operation requirements. After debugging is completed, trial operation and debugging should be carried out to ensure the normal operation of the system. The system maintenance should be carried out regularly, including cleaning the sprinkler head, checking the sealing of pipes and connectors, and replacing aging or damaged parts.
