摘要
阐述了柱面气膜密封的性能特点,用Proe建立了无槽模型、T型槽模型,用专业网格划分软件Hypermesh划分网格,在Fluent中分析了操作参数对2种柱面气膜密封的影响,结果表明T型槽结构具有更好的动压效应,转速、介质粘度和压差等操作参数对柱面气膜密封性能有较大影响。
Expounds the characteristics of the cylinder gas film seal,No slot model and T slot model were set up by using the Proe,Models were meshed with professional software Hypermesh,The operation parameters on the influence of two kinds of cylin-der gas film seal was analyzed by the fluent software,The results show that T slot structure has the better dynamic pressure effect, Operating parameters of speed,medium viscosity and differential pressure has great influence on sealing performance of cylinder gas film seal.
