| 摘 要： | 以流体膜为研究对象,建立了新型动静压混合润滑密封端面的三维模型,并利用流体力学软件FLUENT对端面流场进行数值模拟,得出主要结构参数(动压槽深度、静压槽深度、动压槽宽比、静压槽宽比)对端面开启力、两侧泄漏量等密封性能的影响规律。通过分析得出各结构参数的大致范围,从而对新型动静压混合润滑机械密封结构进行了优化。

| Abstract: | A three-dimensional model of the new-type hydrostatic-dynamic hybrid lubrication seals was developed through a search on fluid film.The pressure and velocity distribution of fluid film was simulated by using the software of computational fluid dynamics.The law of influence of structural parameters such as dynamic pressure slot depth,static pressure slot depth,dynamic pressure slot width ratio,static pressure slot width ratio on sealing performances was analyzed.By analyzing the end face opening force and bo... |
