摘要

当前,在国际工程项目中NFPA20 《美国消防协会消防泵设计安装规范》作为通用的消防泵设计安装标准被广泛使用,许多当地政府消防监管部门将其作为消防泵安装的验收标准,理解并严格遵循规范要求有助于项目顺利通过消防验收。规范对设计压力、安全泄压、性能曲线、泵密封形式、驱动机和稳压泵都做了要求,然而它们都是消防泵设计选型、采购评标、安装调试过程中的常见问题。通过参考国际石油公司的设计规范,分析规范在这些方面的要求,给出了压力安全阀压力设定、稳压泵开启方式设定、消防泵性能曲线和驱动机选型的方法。
        At present, the NFPA20 standard for the installation of universal pumps for fire protection is generally used for the fire pump design and installation in the international engineering projects, most of local government fire protection regulations have select it as the standard to certificate the fire pump installation, so understanding and complying with the requirements of the standard will be helpful to pass fire protection acceptance. The requirements of design pressure, pressure safety relief, perfor-mance curve, pump seal type, drivers and stabilized pressure pumps are all reflected in the standard,but they are the typical problems in the fire pump design and selection, tender evaluation and installa-tion and debugging process. Referring to the fire pump specifications of the international petroleum companies, the requirements of the above aspects are analyzed, and methods for the pressure safety valve setting, stabilized pressure pump starting, fire pump performance curve and driver type selection are put forward.
