XBD HY Vertical Fire Pressure Stabilizing Pump type

Key Features

  1. The XBD-HY Vertical Single-Stage Single-Suction Pressure Stabilizing Fire Pump Set   utilizes the XBD-GDL vertical multistage fire pump as its core pump model, making it suitable for   high-pressure environments such as high-rise buildings.
  2. The unit adopts a modular design for easy installation and maintenance, ensuring a reliable water supply   when needed.
  3. Pneumatic pumps provide stable pressure output and effectively reduce the system’s energy   consumption.

Engineering Summary

The XBD-HY Vertical Single-Stage Single-Suction Pressure Stabilizing Fire Pump Set is mainly used for boosting and stabilizing water supply in fire pipeline systems, serving as a supporting pump for fire hydrant systems and other firefighting equipment. With a vertical configuration and small footprint, it is perfectly suited for installation in fire pump rooms or integrated fire systems, meeting engineering requirements with fast response, pressure stability, and operational reliability.

Applications

This system is used for boosting and stabilizing water supply in firefighting pipelines, widely applied in fire hydrant systems, wet automatic sprinkler systems, and other firefighting and domestic water supply applications.

System Configuration

  • Diaphragm Pressure Tank

  • Pressure Stabilizing (Jockey) Pump

  • Electrical Control Cabinet

  • Monitoring and Control Instruments

  • Associated Pipelines and Accessories

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.
