System Components

The XBD-HY Vertical Single-Stage Single-Suction Pressure Stabilizing Fire Pump Set consists of a diaphragm pressure tank, pressure stabilizing pump, control cabinet, instruments, and associated pipelines and accessories, ensuring efficient and stable operation during installation and use.

Design Fundamentals

The design should be based on the required flow rate and water pressure, in combination with the characteristics of fire hydrant and sprinkler systems, ensuring that the system’s needs are met.

Selection and Operational Principles

• Pressure Control: The system controls the start and stop of the pressure tank by setting pressures P1, P2, Ps1, and Ps2, ensuring stable operation during firefighting processes.

• Flow Requirements: The design should be based on the required firefighting flow during the initial stages of a fire, ensuring that it meets the needs of various systems.

Demand Applications

• Fire Hydrant Systems: The water flow in fire hydrant systems ranges from 2.5 GPM to 5 GPM, meeting the requirements for different spray lengths.

• Automatic Sprinkler Systems: Each sprinkler head has a flow rate of 1.0 GPM, ensuring effective fire suppression.

Intermittent Applications

Suitable for applications that require intermittent pressurization, such as temporary firefighting water supply systems during off-peak hours.

Operational Principles

The system ensures stable operation and automatically adjusts based on pressure changes to meet firefighting needs while maintaining long-term stable operation.
