The role and equipment requirements of fire pumps in urban firefighting
Fire pumps play a vital role in urban firefighting, and their functions are mainly reflected in the following aspects:
Provide the amount of water and water pressure required for firefighting: When a fire occurs, the fire pump can quickly and effectively extract water or other fire extinguishing agents from the water source and deliver them to the fire scene, providing sufficient water and pressure to meet the firefighting needs.
Stabilize the pressure of the firefighting system: The fire pump can also maintain the pressure of the system stable, ensuring that when the sprinkler or fire hydrant discharges water, the amount of water and water pressure that meet the firefighting water demand can be immediately discharged.
Support the operation of firefighting equipment: The fire pump provides power for the normal operation of the firefighting equipment, ensuring that the equipment can operate normally, so as to effectively carry out firefighting work.
Increase the reliability of the firefighting system: The fire pump is an indispensable part of the firefighting system, and its stability and reliability directly affect the performance and effect of the entire firefighting system.
Fire pump configuration requirements
Determine the type of water pump based on comprehensive factors: The type of firefighting water pump should be determined based on comprehensive factors such as reliability, installation location, firefighting water source, firefighting water supply design flow and head.
Flow and head requirements: The minimum rated flow of a single fire water pump should not be less than 10L/s, and the maximum rated flow should not be greater than 320L/s.
Pump group configuration: The fire water pump models of the same pump group for fire water supply should be consistent, and there should be no more than 3 working pumps.
Standby pump setting: A fire water pump should be equipped with a standby pump, and its performance should be consistent with that of the working pump. However, if the building height exceeds 50m and the outdoor fire water supply design flow is less than or equal to 25L/s or the indoor fire water supply design flow is less than or equal to 10L/s, a standby pump may not be set.
Power supply requirements: The power supply of the fire pump should comply with relevant specifications to ensure continuous and stable power supply in an emergency.
