| 摘 要： | 对周隙密封进行热弹流研究,分析周隙密封的流场、压力场和温度场。计入热弹变形的作用,比较不同参数如转速和不同密封瓦材料等因素对密封性能的影响。研究表明:密封瓦热膨胀变形非常显著,密封瓦体的热变形为向瓦体外部膨胀,使密封瓦油膜间隙变大,泄流量增大;随着转速的升高,密封瓦的侧泄流量和温升均迅速增加;使用热膨胀率较低的碳碳复合材料,将使密封瓦的侧泄流量和功耗大大降低。

| Abstract: | The performance of plane seals was studied with thermo-elastic dynamic lubrication theory.The flow field,film pressure and film temperature of plane seals were analyzed including the thermo-elastic deformation.The effects of the seal material and rotating speed on the performance of the plane seal were studied.It is found that the sealing bush has obvious thermo-elastic deformation,which makes oil clearance increase and leakage increase.The side leakage and oil temperature increase rapidly with the increase... |
