A stable high-voltage system: a truly peculiar existence

Stabilized high-pressure fire water system: A fire protection system that uses a pressure stabilizing pump to maintain the pressure of the water in the pipeline at 0.7 Mpa or higher. I understand this to be a type of temporary high-pressure water supply system, with a stabilizing flow rate of 10–15 L/S. Then why not lower the pressure as well, to at least 0.1 Mpa? Why set it as high as 0.7 Mpa? Isn’t that a waste of energy?
The steady high-pressure fire protection water system is set at a pressure of 0.7 Mpa to ensure that, in emergency situations, fire water can reach every corner of the building quickly and effectively, especially in high-rise buildings. Higher pressure can overcome the pressure losses and flow resistance in the piping system, ensuring that fire sprinklers or other equipment can function properly. Although this may increase energy consumption, from a safety perspective, it is necessary to ensure the effectiveness and response speed of the fire suppression system. .
There is no pressure-stabilizing pump near the high-pressure system; therefore, in case of a fire, the fire hydrants do not have water available in a timely manner. It is a constant-high-pressure system; thanks to the pressure stabilizing pump, there is high-pressure water throughout the water system, which enables prompt extinguishment of fires. The low flow rate here is only sufficient to address pipeline leaks and maintain the required water pressure in the pipelines. During an actual fire suppression operation, high-pressure water from the pipelines is used first to extinguish the fire; when the pressure drops to around 4 kilograms or when the fire hydrant button is pressed, the main fire pump also starts automatically, and it is this main pump that supplies water for further fire suppression
