远距离供水灭火系统输水压力损失研究

Study on Water Pressure Loss of a Long-distance Water Supply-based Fire Extinguishing System

将远距离供水灭火系统输水压力损失简化为沿程压力损失和局部压力损失两部分进行研究,并将局部压力损失简化为水流经快速密封接头的压力损失,对比分析了流速及输水距离对压力损失的影响。

Water pressure loss of a long-distance water supply-based fire extinguishing system is simplified into two parts, pressure loss along the way and local pressure loss, and the local pressure loss is further simplified as the pressure loss caused when water flows through fast sealing joints. A comparative analysis of the effect of flow rate and water conveying distance on loss pressure is made.
