摘要： A non-contacting rotary face seal assembly includes a first sealing member, including a first sealing face and a first magnetic element; and a second sealing member, including a second sealing face and a second magnetic element. The first and second magnetic elements of the first and second sealing members provide a magnetic repulsion force between the first and second magnetic elements such that the magnetic repulsion force separates the first and second sealing faces before hydrodynamic or hydrostatic forces associated with rotation of the second sealing member become sufficient to prevent the first and second sealing faces from contacting.
摘要翻译：非接触式旋转面密封组件包括第一密封构件，包括第一密封面和第一磁性元件; 以及包括第二密封面和第二磁性元件的第二密封构件。第一和第二密封构件的第一和第二磁性元件在第一和第二磁性元件之间提供磁性排斥力，使得磁性排斥力在与第二密封件的旋转相关联的流体动力学或静水力之前分离第一和第二密封面构件变得足以防止第一和第二密封面接触。
