摘　　要：为探究煤层气压缩机干气密封结构可能的优化路径,以螺旋槽型干气密封为例,在建立干气密封结构仿真模型的基础上,对该结构的压力分布进行分析,基于压力分布结果,进一步针对设备主轴转速、螺旋角度和螺旋槽数量三项主要参数对干气密封结构密封性能的影响开展仿真分析,并据分析结果提出干气密封结构设计与优化的相关建议,以期为今后的研究工作提供参考与借鉴。To explore possible optimization paths for the dry gas seal structure of coal seam gas compressors,taking the spiral groove type dry gas seal as an example,based on the establishment of a simulation model for the dry gas seal structure,the pressure distribution of the structure is analyzed.Based on the pressure distribution results,further simulation analysis is carried out on the impact of the three main parameters of equipment spindle speed,spiral angle,and spiral groove number on the sealing performance of the dry gas seal structure,Based on the analysis results,relevant suggestions for the design and optimization of dry gas seal structures are proposed,in order to provide reference and inspiration for future research work.
