基于Flowmaster的高层建筑消火栓系统超压现象分析

探讨了消火栓在Flowmaster软件中的建模方法,根据其栓口流量—压力数学关系,实现了对消火栓的建模。结合某高层建筑,运用Flowmaster软件对其消火栓系统模拟,得到该系统在不同工况下的压力分布和流量大小,针对实际流量偏大和局部超压现象,通过改变消火栓泵的设计参数,使系统得到优化。

Analysis on overpressure of high-rise building fire hydrant system with Flowmaster

The modeling method of fire hydrant in Flowmaster was discussed,according to the mathematical relationship between flow rate and pressure,the fire hydrant was modeled.Combined with the modeling of the hydrant system of a high building with Flowmaster,the pressure distribution and the flow rate of this system under different work conditions were obtained.According to the phenomenon of the actual flow rate is larger than the designed value and local overpressure,the system was optimized by changing the design parameters of fire hydrant pump.
