摘; 要：在消防给水系统中，消防水泵属于重要的消防设备，在施工工程中应严格按照设计施工图认真进行施工安装及调试，使系统工作压力、超压泄压压力及各减压力阀组压力和消防水池有效容积的利用等均能达到设计要求。否则，对工程检测、竣工验收中不仅会造成无法通过，而且在实施整改过程中，还会出现施工难度高、改造工程量大以及严重影响工程竣工日期等一系列问题。为减少或避免此类问题发生，文章特对消防给水系统应注重的几点结合国家现行标准规范进行说明。

In the construction project， the construction installation and debugging should be carried out strictly according to the design and construction drawings， so that the working pressure of the system， the overpressure relief pressure， the pressure of each pressure reducing valve group and the utilization of the effective volume of the fire pool can meet the design requirements. Otherwise， the inspection and acceptance of the project will not only cause failure， but also lead to a series of problems in the process of rectification and reform， such as high difficulty in construction， large amount of reconstruction and seriously affecting the completion date of the project. In order to reduce or avoid such problems， this paper explains several points that should be paid attention to in the fire water supply system in combination with the current national standards and specifications. Keywords： effective volume; zero flow pressure; design working pressure; system working pressure
