螺旋槽端面密封是液氧、液氢涡轮泵的首选密封形式。研究了电磁加载装置（EMLD）和摩擦力矩测试装置（FTTD）的设计及其在以水为密封液的螺旋槽端面密封界面试验中的应用。在静平衡位置下测量了端面温度、端面摩擦力矩、密封坝处的油膜压力等密封性能参数，并在特定的控制模式下测试了端面闭合力随EMLD产生的轴向载荷变化对密封性能的影响。结果表明，端面密封阻尼器处的压力和端面温度均随转速的升高而升高，全膜润滑时摩擦系数较小。可控密封的分离速度也可以控制，从而帮助密封端面抬起，满足端面非接触状态的条件。此外，随着EMLD和FTTD的应用，密封操作监控成为可能，并实现了具有理想性能的可控面密封。本研究的结果为工程密封设计及其应用提供了很好的参考。
The spiral groove face seal is a prime candidate for application of the liquid oxygen and liquid hydrogen turbopump. The study investigated the designs of the electro-magnetic loading device (EMLD) and friction torque testing device (FTTD), and their application in the interface experiments of face seals with spiral grooves which used water as the sealing fluid. The seal performance parameters, including face temperature, face friction torque, film pressure at the seal dam, were measured under the static balance position, and the effects of the face closing force, which varied with the axial load generated from the EMLD, on the seal performance were tested under a specific controlled mode. The result indicated that both the pressure at the seal dam and face temperature increased with the rotating speed and that small friction was obtained when the face seal was fully film-lubricated. The separation speed of the controllable seal could also be controlled, which helped seal faces lift off and met the conditions of the face noncontact status. Additionally, with the application of the EMLD and FTTD, seal operation monitoring was rendered possible and a controllable face seal with desirable performance was achieved. The findings of the current study lend great insights into engineering seal design and its applications.
