多台通风机并联于复杂通风系统工况分析

摘要

多台风机联合运行的矿井,总伴随风机之间相互作用的情况. 在不破坏矿井通风系统正常状况的情况下,研究其相互之间影响的规律,是通风管理的一项重要内容. 本文介绍了一种简便、相比之下更为准确的数学分析方法用以分析复杂通风机联合运行的模型,分析了N台通风机联合运行时通风系统的干扰性,并在某矿工作面做了相应验算,结果表明,该推导数学模型能够指导计算各个风机的风量变化,对于区域风量的调节具有指导意义.%The coal mine of joint operation of multiple fans always accompanies interaction between the fans. Under the condition of which do not destroy the mine ventilation system in normality, study the law of the mutual in-fluence, which is an important content.This paper introduces a simple and convenient, compared with more accurate mathematical analysis methods are used to analyze the complicated ventilator joint running model.Analyzes the inter-ference of ventilation system when joint operation of N ventilators and carries out the corresponding checking in a coal mine working face.The results show that the derived mathematical model can guide calculating each fan air volume change, for regional air volume regulation is of guiding significance.
