Working Principle of Pressure Regulating Pump

Pressure stabilized pump and booster pump are both constant pressure facilities of fire pump. When the pressure stabilizing pump runs in the sprinkler and fire hydrant, the booster pump works in the sprinkler and fire hydrant, but the water pressure of fire water is insufficient, when the water pressure needs to be increased.

Pressure stabilized pump is different from booster pump. It is used to keep the self-spraying system and hydrant system in the required pressure condition. Once the water is discharged, it can meet the water pressure and quantity requirements for fire water. Its function is very obvious. The working principle of the pressure stabilization pump, so the booster pump referred to in the code essentially refers to the pressure stabilization pump, especially the pressure stabilization pump of the automatic sprinkler fire extinguishing system.

When the non-pneumatic water tank is matched, the flow rate of the pressure stabilizing pump is calculated according to the water quantity of not more than one nozzle or one hydrant. When a pneumatic water tank is set up, the water supply and pressure guarantee of the system are implemented by the pneumatic water tank. The flow rate of the pressure stabilizing pump only needs to meet the flow requirement of the pneumatic water tank, that is, the flow rate of the pressure stabilizing pump should consider the regulating volume of the pneumatic water tank. At this time, the flow rate of pressure stabilized pump should be determined according to the total volume of air and water in the tank of pressure water supply equipment and the calculation formula of the volume of water in the tank.
