摘　　要：为进一步提升矿用离心通风机运行效率,以FBY型矿用隔爆型离心通风机为研究对象,针对其叶轮效率偏低问题,通过数值模拟分析方法,确定此问题的根源在于通风机间隙流动损失,降低间隙尺寸有助于减小损失。由此引入刷式密封结构,对该矿用离心通风机内部间隙进行优化调整。从仿真分析结果来看,优化后的通风机结构有效抑制了气流的间隙损失,并使叶轮效率提升了约1.3%,表明本次矿用离心通风机间隙流动损失抑制方法相对较为可行。In order to further improve the operating efficiency of mine centrifugal ventilator,FBY type mine explosion-proof centrifugal ventilator is taken as the research object,and in view of the problem of low impeller efficiency,it is determined by numerical simulation and analysis that the root cause of this problem lies in the flow loss of the ventilator gap,and the reduction of the size of the gap helps to reduce the loss.As a result,the brush seal structure is introduced to optimise the internal clearance of the mine centrifugal ventilator.From the simulation results,the optimised ventilator structure effectively suppresses the airflow gap loss and improves the impeller efficiency by about 1.3%,indicating that the method of suppressing the gap flow loss of the centrifugal ventilator for mining is relatively feasible.
