摘要
利用通风系统节点风流平衡关系和回路阻力平衡关系,基于空气动力学特征的制约关系,分析了井下通风系统中风门对各分支的影响,以及某些分支安装风门后,其他分支的风量和阻力变化的分析模型,给出了度量风量和阻力反应敏感性强弱的方法,并提出了通风系统风门安装的最优调节模型,通过这些模型可预先进行运算分析,对于风门的使用具有较好的指导作用。
The constrained relationship of air dynamics properties among branches in the underground ventilation system is analyzed by the laws of flow balance in nodes and pressure balance along circuits of ventilation system and an analytical model for variation of its air volume and pressure after the installment of ventilation doors on some branches is developed to produce a method to measure the strength of sensitiveness of volume and pressure for each branch.An optimization control model for the installation of air door in the ventilation system is given and these models are capable to conduct calculations and analysis in advance and can serve as a good guidance to the usage of air door in ventilation system
