Generally, the pressure is stabilized by a stabilizing pump. When fire water is needed, the system pressure is lower than the set pressure, and the main pump starts to pressurize.
In case the pipeline pressure does not meet the standard, it will automatically replenish the pressure.
The fire pump does not always work, but it is not in the off state. Once the fire alarm is triggered, it can be put into operation immediately. The fire pump has two operating modes, automatic and manual. The main control is linked with the fire control center, and manual control requires manual start. However, when it works, the pump will start, which can be driven by electricity or diesel engine in case of power failure.
All pipelines have a pressure resistance limit, and when the pressure they are subjected to exceeds this value, they will burst.
