Since there is already a diesel generator room, a fire backup pump is needed, and it should be a diesel engine-powered pump
Thread Content
Since there is already a diesel generator room, it is still necessary to comply with the provisions of Article 8.3.8 of the \"Fire Protection Design Code for Petrochemical Enterprises (2018 Edition)\” (GB 50160-2008): fire backup pumps should be diesel engine-driven pumps. Is it specified, or is a diesel fire pump also required?
I don’t quite understand this standard, but it seems there is a difference between the two!
Personally, I believe diesel fire pumps should not be used in daily operations and should be kept separate as a backup.
First of all, it needs to be clear whether your diesel generator set is used specifically for the water pumps or shared with the power supply facilities If there is a power outage in the electronic control system, can this system replace the power supply from the main network? Also, is the power outage incident within your power supply system? If everything falls within the scope of your coverage, then it may not be necessary to have this system. Opinions from imitators, for reference only.
Separate standby diesel engine to drive the fire pump
I agree with the view expressed on floor 4. The purpose of installing diesel fire pumps is to have fire-fighting water available in emergency situations. If your generator can ensure a power supply for the fire pumps during emergencies, then theoretically it is feasible as long as the risks are properly assessed and controlled. However, I recall that this requirement has been mandatory in new, modified, and expanded projects since 2018.
The main pump is an electric pump, while the backup pump is a diesel engine pump; 100% backup capacity is required, and the fuel supply must cover the 6-hour operation needs of the diesel engine pump. This is a mandatory requirement that must be strictly enforced.
Code for Fire Protection Design of Petrochemical Enterprises 8.3.8 Fire pumps shall be equipped with dual power sources； When a diesel engine is used as the power source, its fuel reserve should be sufficient to enable the unit to operate continuously for 6 hours.
