コンプライアンス概要

この概要は現在英語のみで提供しています。

適用範囲

This standard applies to the design, manufacturing, and acceptance of fire pumps and fire pump units used for conveying water, foam mixture, or foam concentrate as the primary extinguishing agents. It covers various types including vehicle-mounted, vessel-mounted, portable, fixed, trailer-mounted, and booster fire pumps. It is mandatory for all manufacturers producing fire pumps for the Chinese market. The standard specifically excludes regulations for deep well and submersible fire pumps that were present in the previous version.

技術要求

The standard specifies comprehensive requirements across multiple categories. For vehicle-mounted fire pumps, it defines structural, material, and performance parameters based on pressure ratings (low, middle, high, and combinable pressures), including specific operating conditions for flow and pressure at various suction depths. Manufacturers must ensure impeller balance performance meets G6.3 grade requirements. For fixed fire pump units, the standard details requirements for structure, materials, and mechanical performance, with specific additional requirements for electric motor-driven units (referencing GB 18613 and GB 30254 for efficiency) and diesel engine-driven units. Diesel engine requirements cover battery systems, fuel tank capacity, cooling systems, and exhaust routing. Diesel engine power must be corrected for non-standard environmental conditions. The standard also outlines requirements for portable fire pump units, including weight limits (max 180kg), wheel specifications, and tilt performance. For foam concentrate fire pump units, it mandates the use of corrosion-resistant materials like 06Cr19Ni10 stainless steel and specifies safety valve pressure settings. Additional requirements are provided for vessel-mounted, trailer-mounted, and booster fire pump units.

試験方法

The standard details testing procedures for all fire pump types. Key tests include: Structural and Material Inspection (visual and dimensional checks), Main Technical Parameter Testing (measuring flow, pressure, and power relationships under specific suction depths), Mechanical Performance Testing (sealing and hydrostatic strength tests), Vacuum and Priming Performance Testing (measuring maximum vacuum and priming time reliability), and Continuous Operation Testing (running pumps under rated and overload conditions to check temperature and vibration limits). Specific tests for diesel engines include battery capacity, cooling system efficiency, and speed governor performance.

よくある質問

What products are regulated under GB 6245-2025?

GB 6245-2025 regulates fire pumps and fire pump units used for conveying water, foam mixture, or foam concentrate. This includes vehicle-mounted, vessel-mounted, portable, fixed, trailer-mounted, and booster fire pumps, as well as units driven by electric motors, diesel engines, gas turbines, gasoline engines, and water turbines.

Are there any updates from the previous version of GB 6245?

Yes, GB 6245-2025 replaces GB 6245-2006. Key updates include changes to terminology, model numbering rules, and technical parameters for fixed fire pump units. It adds requirements for impeller balance, deep well pump bearing spacing, diesel engine cooling water loops, and control cabinets for both electric and diesel fire pump units. It also removes regulations for deep well and submersible fire pumps found in the 2006 version.

What are the specific requirements for portable fire pump units under this standard?

Portable fire pump units must have a total weight not exceeding 180kg. Units under 100kg require at least 2 carrying handles, while units 100kg and above require at least 4 handles. They must pass a tilt test, operating normally while tilted 25° in four directions. They also require specific fuel tank capacity for continuous operation and must start within 30 seconds.

The summary above provides a high-level overview of GB 6245-2025.
