Champ d’application

This standard applies to gas pressure fixed water supply equipment used for fire-protection, which utilizes a pressurized gas tank as the core component to supply water to fire-fighting networks at a set pressure. It is primarily designed for fixed fire-protection systems installed in buildings. Equipment with similar working principles may also refer to this standard, though it specifically regulates emergency and pressurization types of gas pressure water supply equipment.

Exigences techniques

The standard specifies comprehensive requirements for the design, construction, and performance of the equipment. Key areas include basic parameters such as minimum gas supply pressure, rated working flow, and effective water volume. It mandates that equipment must include a pressure tank, pump units, piping valves, and a control cabinet. The standard details control functions for stable pressure operation, fire-fighting state activation (manual, remote, and automatic), and pump switching. Equipment must feature an inspection function with a maximum cycle of 360 hours and maintain operation records for at least 180 days. Additionally, it outlines requirements for water supply capacity, ensuring the tank provides the nominal effective water volume and the pumps meet specific flow and pressure criteria under continuous operation. The standard also sets limits for sealing performance, hydrostatic strength, and operating noise (max 90dB(A)).

Méthodes d’essai

Testing procedures include verifying basic parameters and structural components against technical documents. Key tests involve control function tests (simulating pressure drops and alarms to check pump activation), water supply capacity tests (measuring effective and supplementary water volumes), and continuous operation tests (24h for stabilizing pumps, 6h for fire pumps). Further evaluations cover sealing performance under 1.1 times the maximum working pressure, hydrostatic strength at twice the maximum working pressure, and environmental adaptability tests for the control cabinet, including low/high temperature, constant damp heat, and vibration resistance.

Questions fréquentes

What products are regulated under GB 27898.1-2011?

It regulates gas pressure fixed water supply equipment used for fire-protection, specifically categorizing them into emergency types (without fire pumps) and pressurization types (with fire pumps).

Are there any mandatory chapters in GB 27898.1-2011?

Yes, Chapters 5, 7, and 8 are mandatory, covering technical requirements, inspection rules, and nameplates/operation manuals, while the rest are recommended.

What are the key performance tests required for the control cabinet?

The control cabinet must undergo environmental adaptability tests, including low temperature (+5°C), high temperature (+55°C), constant damp heat (+40°C, 93% RH), and vibration/transportation tests to ensure structural integrity and reliable operation.
