摘要
将水带的压力损失分为沿程阻力和局部阻力两部分进行研究,其中局部阻力损失细化为弯曲损失和接扣损失.主要分析沿程阻力损失系数、粗糙度、局部损失系数、水带压力、水带直径和流量对水带压力损失的影响.通过对这些影响因素的分析和大量实验,对水带压力损失公式进行简化,得出了水带压力损失的简化公式以及查询图表.
The fire hose＇s pressure loss research is divided into two parts. The one is research of onway resistance and the other is of local resistance, including bending resistance and coupling resistance. Research is mainly carried out for the influences on the fire hose＇s pressure loss, such as.on-way resistance coefficient, roughness, local resistance coefficient, hose pressure, hose diameter, flow and soon. By the analysis on these influencing factors and according to a large amount of experiments results, calculation formulas are simplified, then reduced formula and correlated diagram are given out.
