摘要: 为厘清特高压换流变压站举高消防机器人输送多种灭火介质的可靠性,选用Fluent对水、泡沫液和压缩空气泡沫在包含长距离运输、高度变化的管道内的压降进行数值模拟研究。研究结果表明:在供液流量2 000~4 000 L/min范围内,3种灭火介质流体在硬管中的压降随着流量的增加而增大,供液流量4 000 L/min的各灭火介质压降最大可达2 000 L/min的3.4倍。在相同的流量下,泡沫液与水的压降差值较小,而压缩空气泡沫的压降远远大于水和泡沫液。受摩擦阻力与局部阻力影响,硬软管接驳口处存在较大的压降;管道喷出口高度变化对上升段影响显著,高度越高,压力衰减越快,15 m高度的管道压降系数可达到6 m管道的1.9倍。

Abstract: In order to clarify the reliability of the extra-high voltage transformer station lifting fire robot to transport a variety of fire-fighting agents, Fluent was used for water, foam and compressed air foam in the pipeline with long-distance transport, height changes in the pressure drop numerical simulation study. The results of the study show that: in the range of supply flow 2 000~4 000 L/min, the pressure drop of the three extinguishing agents fluids in the hard pipe increases with the increase of flow rate, and the supply flow 4 000 L/min of each extinguishing agents pressure drop can be up to 3.4 times that of 2 000 L/min. At the same flow rate, the difference in pressure drop between foam and water is small, while the pressure drop of compressed air foam is much greater than that of water and foam. Affected by frictional resistance and local resistance, there is a large pressure drop at the hard hose connection port; changes in the height of the pipe nozzle have a significant effect on the rising section, the higher the height, the faster the pressure drop, the pressure drop coefficient of the pipe at a height of 15 m can reach 1.9 times that of the 6 m pipe.
