Issues with fire foam in the tank area
Thread Content
For the fire foam system in the tank area (balanced foam tanks), a separate foam supply pump is not required; the fire water in the fire protection pipeline can be utilized instead. In this case, the fire pump starts when the pressure falls below a certain level; furthermore, it starts when the fire cooling water is activated, and at that point it is necessary to check whether the pressure in the fire protection network meets the required standards. Under such circumstances, how can the foam supply pressure be maintained? Are there any good measures to ensure this? This post was last edited by xahoo on 2009-4-20 10:13]
First, whether a foam pump is needed depends on the type of your foam system. If it’s a balanced-type system, then a foam pump is required, as it offers better performance compared to systems that don’t use one.
In the fire foam system for tank areas (balanced foam tanks), it is not necessary to install a separate foam supply pump; it is feasible to use the fire water available in the fire protection pipeline network. To ensure fire safety in industries where flammability and explosiveness are a concern, it is essential to maintain a certain pressure in the fire protection pipeline network at all times; therefore, a pressure stabilizing pump can be added to ensure such pressure.
The pressure stabilizing pump plays a role in stabilizing pressure on a daily basis; in the event of an accident, when the pressure in the pipeline network drops to a certain level, does the fire pump start up. The pipeline network pressure is dropping, and foam requires 5 minutes to reach the tank area, right? The flow rate of the pressure stabilizing pump is very low.
This relates to the pressure stabilization of fire protection water networks; generally, companies install fire pumps and pressure stabilization pumps to maintain the network within a certain pressure range. When the pressure is below the set range, the pressure stabilizing pump starts automatically ； When it exceeds the range, the pressure stabilizing pump stops automatically. Therefore, the pressure in the fire water piping system must be guaranteed!
At the beginning, a certain pressure must be maintained in the fire protection piping system, which can be achieved by using a pressure stabilizing pump
