Champ d’application

This standard applies to fire-protection pressure boosting and stabilizing water supply equipment, including stabilizing, boosting, and combined types. It covers equipment used to maintain pressure stability and meet fire-fighting needs in fire water supply systems. Manufacturers must ensure these fire water supply devices comply with these specifications. Equipment with similar working principles may refer to this standard. It references GB 27898.1-2011 and GB 27898.2-2011 for related requirements.

Exigences techniques

The standard specifies basic parameters, including minimum limits for the gas-stop/charging pressure of the air pressure tank, fire-rated working flow, and fire-rated working pressure. It also requires specific minimum thresholds for compensation water volume or effective water volume. It outlines requirements for equipment composition and components, mandating the inclusion of pump units, piping valves, measuring instruments, and control cabinets. Stabilizing type equipment must include an air pressure tank, while suction-pressure-regulated devices require a flow stabilizer compensator. The standard details control functions such as stabilizing operation, fire operation state activation, and pump switching. The equipment must feature automatic inspection and operation recording functions. For suction-pressure-regulated equipment, there are strict requirements to prevent negative pressure hazards. It covers water supply capacity, continuous operation, sealing performance, and water pressure strength. The air pressure tank, capsules, and control instruments must meet specific safety and performance criteria, referencing GB 150 and TSG R0004 for pressure vessel safety.

Méthodes d’essai

The standard mandates various testing methods, including basic parameter checks, control function tests, and water supply capacity tests. It also requires continuous operation, sealing performance, and water pressure strength tests to verify the equipment's durability and safety. Noise measurement is conducted according to GB/T 3222.2. Type testing and factory testing must be performed following strict inspection rules to ensure compliance.
