摘要(Abstract)：

以不同工况下的机械密封环为研究对象,依据接触表面的温度,对各种工况时密封端面的接触状况及温度变化趋势进行了分析。结果表明:在极端工况下,机械密封环温度远低于相应材料的允许使用上限;在正常工况下,密封环由于摩擦生热引起的温升较小,由密封介质传导入密封环的热量引起的温升较大。机械密封在不同介质温度和不同密封压力下均可保证较好的运行性能。在极端工况下,密封动静环等效M ises应力均在较低的水平,不会导致密封环的失效破坏。由于密封压力作用引起的密封端面变形,密封端面液膜厚度沿压降方向呈发散分布;在端面外径处动静环将会产生局部接触磨损,密封介质温度对端面液膜厚度影响较小。
The different conditions of mechanical seal ring as the research object,based on the contact surface temperature,on various conditions of seal contact status and temperature change trend are analysed.The results showed that: under extreme conditions,the mechanical seal ring temperature is far less than the corresponding material allows the use of the cap;in normal working condition,the sealing ring due to friction caused by Wen Sheng small,by the sealing medium is transmitted into the sealing ring heat caused by Wen Sheng large.Mechanical seal in different medium temperature and different sealing under pressure can guarantee good performance.In extreme cases,seal ring Mises equivalent stress at the lower level,does not lead to the failure of sealing ring.Because the sealing pressure effect caused by the seal face deformation,seal liquid film thickness along the direction of pressure drop is a divergent distribution;in the end the outside diameter of dynamic and static rings will generate local contact wear,sealing medium temperature on the end surface of liquid film thickness effect.
