摘要
针对双风井风机并联运行的特性问题,文中以宝积山煤矿通风系统为例,采用网络解算方法,分别研究了通风网络和通风机的特性。通风网络方面,公共网络风阻与风井回风段风阻比值越大,通风压降也越大,另外,通风功率呈现先增大后降低的规律;通风机方面,当通风机性能工况调整时,对公共风路通风压降有影响,同时也影响另一通风机性能,如果功率增大,公共风路压降增大,另一通风机工况点上移。研究规律对于现场调整通风系统具有指导作用。
For parallel-operation characteristics with double fans in ventilation shafts, taking the ventilation system of Bao-Jishan Coal Mine as an example, method of using network simulation is applied to study the characteristics of ventilation network and fan. In terms of characteristics of ventilation netting the working condition of the fan, also affecting the characteristics of another fan. If fan power increase, the ventilation power of public network will drop greatly, the working condition will move upside else. The result of study would be guidance for adjusting the ventilation system.
