多台风机并联运行的稳定性及多级机站通风系统的可行性和优越性是当前国内冶金矿山通风的研究课题之一,本文依据有关资料,试图阐明可能出现的技术难点,供研究试验工作参考。英国70年代初期就在煤矿采用了带墙多风机并联的机站,最庞大的辅扇机组达12台串并联。关于风机并联运行的稳定性问题,瑞典吕勒欧大学采矿工程博士鲁斯顿副教授在长沙座谈会上说,瑞典基鲁纳矿所用的辅扇在运转中没有出现不稳定现象,其扇风机特性曲线是不带驼峰的单调下降曲线。其
The stability of multi-units in parallel operation and the feasibility and superiority of multi-station station ventilation system are one of the research topics of ventilation in metallurgical mines at present. Based on relevant information, this paper attempts to clarify the technical difficulties that may arise for the research and experimental work reference. The United Kingdom in the early 70s at the mine used in parallel with the wall fan station, the largest auxiliary fan unit up to 12 units in parallel. Regarding the stability of parallel operation of wind turbines, Dr. Ruston, Ph.D., mining engineer at the University of Luleå in Sweden, said at the Changsha Symposium that the auxiliary fans used at Sweden’s Kiruna mine did not exhibit any instability during operation, and its fan characteristics The curve is a monotonically decreasing curve without humps. its
