高海拔地区消防泵和配套电机的设计选择

摘要

以西藏拉萨某沥青库消防设计为例，探讨了环境温度和海拔高度对电机功率的影响，给出了消防泵配套电机容量的选择计算方法。电机容量在考虑规定的备用系数基础上，对高海拔地区需再加上高原修正系数。%Taking the fire protection design of the pitch storage tank in Lhasa Tibet as an example, the in‐fluences of environment temperature and altitude on motor power were discussed, and then, the optional calcula‐tion methods of the capacity of fire pump matching motor were put forward. It was indicated that, calculating mo tor capacity in high altitude localities should based on the specified reserve factors and take correction factors also.
