Introduction
Fixed fire-fighting water supply equipment is permanently installed inside a building, configured with components according to the needs of the water-based fire extinguishing system, and operates according to a pre-set mode.
Complete sets of equipment for supplying water for fire fighting. Based on equipment function, they are divided into fire-fighting pneumatic water supply equipment, fire-fighting automatic constant pressure water supply equipment, and fire-fighting booster water supply equipment.
Water equipment, fire-fighting pressure-stabilizing water supply equipment, fire-fighting gas pressure-pressurized water supply equipment, fire-fighting dual-power water supply equipment, etc.
GB 27898 "Fixed Fire Water Supply Equipment" is a mandatory national standard guiding the design, inspection, and use of fixed fire water supply equipment products in my country.
The standard is proposed to consist of five parts.
---Part 1.Firefighting Pneumatic Water Supply Equipment. The purpose is to standardize the requirements, test methods, and inspection rules for firefighting pneumatic water supply equipment.
This includes ensuring the equipment's ability to continuously supply water to the fire protection network at the set pressure, with the pressure tank as its core component.
---Part 2.Automatic Constant Pressure Water Supply Equipment for Firefighting. The purpose is to standardize the requirements and test methods for automatic constant pressure water supply equipment for firefighting.
Inspection rules and other content ensure that the equipment achieves constant pressure for fire fighting using specific control methods or by utilizing the inherent flow and pressure characteristics of the pump set.
The power of water.
---Part 3.Firefighting Pressure Boosting and Stabilizing Water Supply Equipment. The purpose is to standardize the requirements for firefighting pressure stabilizing and boosting water supply equipment.
Requirements, test methods, inspection rules, etc., to ensure that the equipment maintains stable pressure in the fire water supply system or adopts fire-fighting measures.
The pump unit has the ability to increase the pressure of the fire water source to meet the fire extinguishing needs of the fire water supply system.
---Part 4.Firefighting Gas Pressurized Water Supply Equipment. The purpose is to standardize the use of compressed gas pressure reduction and replacement methods to supply water to fire protection pipe networks.
The requirements, test methods, and inspection rules for fixed fire-fighting water supply equipment are specified to ensure that the equipment maintains its rated fire-fighting working pressure.
The ability to supply water to the fire protection network.
---Part 5.Dual-Power Firefighting Water Supply Equipment. The purpose is to standardize the use of dual-power fire pump sets, including both electric motor and engine-driven fire pump sets.
The requirements, test methods, and inspection rules for fixed fire water supply equipment that continuously supplies water to the fire protection network using a combination of force methods are specified.
Product quality.

3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
In fire-fighting operation, compressed gas is depressurized and then injected into the pressure water tank, displacing the fire-fighting water stored in the tank, and filling it with the rated water within a specified time.
Water supply equipment that supplies fire-fighting water to the fire-fighting pipeline network under working pressure.
Note. It is usually composed of components such as a pressure tank and accessories, a pressure stabilizing pump set, a top pressure system, pipeline valves and accessories, measuring and control instruments, and a control cabinet.
3.2
gas driven system
In fire-fighting gas pressurized water supply equipment, the general term refers to the components related to the storage, monitoring, pressure reduction, and release of compressed gas.
3.3
The compressed gas in the top-pressure system is collected from the gas storage cylinder group and then concentrated and depressurized before being filled into the pressure water tank. This is a fire-fighting gas top-pressure water supply equipment.
