Compliance overview
Scope and applicability
This standard applies to constant pressure automatic water supply equipment used for fire-protection. It covers the terms, classification, requirements, and testing methods for these systems. Equipment with similar constant pressure working principles may also refer to this standard. It is essential for manufacturers of fixed fire water supply systems and fire-fighting pump units.
Technical requirements
The standard specifies the structural and component requirements for fire-protection water supply equipment, including pump units, piping, valves, and control cabinets. Components must be compactly arranged and securely installed for easy maintenance. It references GB 150 for pressure vessels and requires specific pressure ratings for safety. Control functionality is a core focus, detailing requirements for stabilization pressure operation, fire pump startup modes, and pressure control accuracy. The equipment must feature automatic and manual pump switching capabilities during faults. It also mandates periodic inspection functions and a running record device to log pressure, alarms, and pump status for at least 180 days. The standard outlines performance criteria for water supply capacity, ensuring both pneumatic tanks and fire pump groups meet specific volume and pressure delivery metrics. It sets limits for continuous operation stability, requiring the system to run without failure under defined durations. Additionally, it specifies sealing performance, hydrostatic strength, and maximum operating noise limits. Requirements for control cabinets and variable frequency drives are detailed, ensuring environmental adaptability and electromagnetic immunity. Variable frequency drives must automatically switch to power frequency operation upon failure to maintain fire water supply. The standard also defines inspection rules, labeling, and packaging guidelines.
Testing methods
The standard outlines various testing procedures including basic parameter checks, structural component inspections, and control function tests. It mandates continuous operation tests to verify stability under prolonged use. Sealing performance and hydrostatic strength tests are required to ensure no leakage or deformation under high pressure. Noise measurement is conducted according to GB/T 3222.2, and specific tests for variable frequency drive immunity are referenced from GA 61.
FAQs
What products are regulated under GB 27898.2-2011?
