摘要
利用回路阻力平衡定律提出了分析矿井通风系统中多台风机同时运行时相互影响的通用方法,结果表明:当通风系统多台风机同时运行时,各风机间会出现反向干扰、正向提携和没有影响的几种情况;若风机A对风机B具有反向干扰作用,则风机B对风机A也具有反向干扰作用;若风机A对风机B具有正向提携作用,则风机B对风机A也具有正向提携作用;若风机A对风机B没有影响,则风机B对风机A也没有影响。该方法解决了如何分析任意复杂通风系统中各风机间相互影响的问题,为通风网络中风机的正确选型、定位、安装、风量调节和提升风机运行效率提供了理论依据。
An generalized analytical method for interaction among many fans in underground ventilation system is put forward using the circuit resistance balance law,the results show that when many fans run at the same time in a ventilation system,there are reverse interference,positive support and no interference phenomena;if fan A has a reverse effect on fan B,fan B also has a reverse effect on fan A;if fan A has a positive support on fan B,fan B has also a positive support on fan A;if fan A has no effect on fan B,fan B has also no effect on fan A.This method solves the problem of how to analyze the interaction among many fans in any complicated ventilation system and provides a theoretical basis for correct selection,positioning and installation of fans,ventilation adjustment and fan operation efficiency upgrading.
