    • A mechanical seal device for obtaining appropriate sliding properties under any conditions, such as a pressure of seal is low or high. Both first grooves 463 and second grooves 464 are formed on a sliding face 46 of a stationary ring 46. The first grooves which are not in communication externally and act for reducing contact resistance of a sliding face by a dynamic pressure action when a rotary shaft rotates, the second grooves act for reducing the contact resistance of the sliding face constantly by introducing a pressure from external. Thus, a mechanical seal device which is available to seal sealed fluid under an appropriate dry contact status wherein a sliding face load is reduced in any condition can be provided.
    • 用于在诸如密封压力的任何条件下获得适当的滑动性能的机械密封装置低或高。 第一凹槽463和第二凹槽464都形成在静止环46的滑动面46上。当旋转轴旋转时,不与外部连通的第一凹槽用于通过动压力降低滑动面的接触电阻 ,第二槽用于通过从外部引入压力来不断地减小滑动面的接触电阻。 因此,可以提供在适当的干接触状态下可用于密封密封流体的机械密封装置,其中在任何情况下滑动面负载减小。

    • A pumping ring 46 producing an axial flow of sealed flow is secured to a rotary shaft 6 at an axial position different from a rotary ring 56 so that the sealed fluid positioned in the sealed space 33 flows along the axial direction of the rotary shaft 6. A discharge hole 14 is formed on an inner circumferential surface of a seal cover 8 positioned in the downstream side of the axial flow of the sealed fluid resulting from a rotation of the pumping ring 46. An inflow hole 15 is formed in the upstream side of the axial flow of the sealed fluid resulting from the rotation of the pumping ring 46, so that the sealed fluid discharged from the discharge hole 14 returns to the inside of the sealed space from the inflow hole 15. On the inner circumferential surface of the seal cover 8 provided with the discharge hole 14, a baffle member 18 is provided so that it protrudes radially inward in order to block the flow of the sealed fluid along the rotating direction of a retainer 52 and orient the sealed fluid toward the discharge hole 14.
