| 摘 要： | 用有限单元法对柱塞泵密封圈进行了分析,获得了橡胶密封圈与柱塞间接触应力的分布规律以及接触应力与工作介质压力的关系。计算表明:橡胶密封圈在工作介质压力的作用下,有"偏离效应"的存在,即在密封圈的接触宽度上,唇部受拉伸,根部受压缩,主密封在靠近唇部位置;同时,主密封带的位置不随工作介质压力的变化而变化,且最大接触应力与工作介质压力之比为1 23。为润滑状态和密封机理的分析提供了计算依据。

| Abstract: | Based on finite element analysis method,the contacting stress between plunger and seal was discussed in detail.The paper presented distribution law of contacting stress between plunger and rubber sealing ring,and also analyzed the relationships between the contacting stress and the working pressure.Under the action of working medium pressure,it indicated the "centripetal effect" in rubber seal ring exised.i.e.,along the contacting length of seal ring,the lip of seal ring was extended,the root of seal ring was compressed,and the main sealing region did not vary with the medium pressure,and the ration of the maximum contacting pressure to the working medium pressure was 1.23. It provided the theoretical support for the analysis of lubrication and seal mechanism. |
