《消防给水及消火栓系统技术规范》(GB50874-2014)实施后,关于稳压泵的设置及设计压力的计算,以及设置稳压泵的临时高压消火栓系统的系统压力的计算成为本规范的重点。在实际工程中,受建筑限高的约束,几乎所有的消火栓系统均设置稳压泵来保证最不利消火栓的静压达到使用要求,而消火栓系统压力的关系到消火栓系统的分区和管材的选用。由于这些内容散落在规范的各章节中,不便查阅,因此本文以全新的逻辑顺序将这些内容进行归纳整理,以便于查阅和运用。
After the implementation of the “Technical Specification for Fire Water Supply and Fire Hydrant System” (GB50874-2014), the calculation of the setting of the surge pump and the design pressure and the calculation of the system pressure of the temporary high pressure fire hydrant system of the surge pump are the focus of this code. In practical engineering, due to the restriction of building height, almost all of the fire hydrant systems are equipped with a pressure regulating pump to ensure the hydrostatic pressure of the most unfavorable hydrant meets the requirements of use. The pressure of the hydrant system is related to the partition of the hydrant system and the selection of pipes. Because these contents are scattered in the norms of each chapter, inconvenience to check, so this article in a new logical order to summarize these elements for easy access and use.
