Pipeline design of fire pump system 



1. The working pressure level of the equipment, equipment, pipe fittings, valves and fittings used in the fire water supply system should be higher than that of the fire water supply system, and the safety and reliability of the system should be guaranteed at the maximum possible operating pressure.           
2. The system working pressure of low-pressure fire water supply system should be determined according to the system working pressure of municipal water supply network and other water supply networks, and should not be less than 0.60 MPa.           
3. The working pressure of the high-pressure and temporary high-pressure fire water supply system shall be determined according to the maximum possible operating pressure of the system when supplying water, and shall comply with the following provisions:           
3-1. The system working pressure of high-pressure fire water supply system for high-level fire pool and water tower should be the maximum static pressure of high-level fire pool and water tower.           
3-2. The working pressure of the high-pressure fire water supply system directly supplied by municipal water supply network should be determined according to the working pressure of municipal water supply network.           
3-3. The working pressure of the temporary high-pressure fire water supply system stabilized by a high-level fire water tank should be the sum of the zero flow pressure of the fire pump and the maximum hydrostatic pressure of the suction port of the pump.        
3-4.The system working pressure of the temporary high-pressure fire water supply system stabilized by the pressure stabilizing pump should be cancelled when the zero flow rate of the water-proof pump and the maximum static pressure of the suction port of the fire-fighting pump are combined with the larger value of the two when the pressure stabilizing pump maintains the system pressure.
