    摘要: A mechanical face seal device includes a bellows assembly comprising a bellows member of resilient material having axially spaced mounting portions interconnected by an intermediate foldable portion, one of said mounting portions being adapted to be fixed relative to a rotary component whilst the other is in torque transferring relationship with a rotary annular seal member, and a biasing means for diasing the rotary annular seal member against the stationary annular seal member. An essentially stiff support member having a predetermined radial dimension is provided for axially supporting the rotary annular seal member and is itself supported by the bellows member. The bellows assembly further comprises a driving housing having axially spaced force transferring portions, of which one is in force transferring relationship with the mounting portion of the bellows member at the annular seal member side, whilst the other one is in force transferring relationship with the mounting portion at the rotary component side thereof, wherein the force transferring portion facing the mounting portion at the component side has an internal radial dimension which is less than the external radial dimension of the support member and greater than external radial dimension of the rotary annular seal member.

    摘要: A mechanical face seal assembly for sealing a rotating member with respect to a stationary member comprises at least a pair of cooperating annular sealing elements, of which one is mountable in a non-rotating manner with respect to the stationary member and the other for common rotation with the rotating member. Between the rotating member and the non-rotating sealing element an annular space is defined, the radial dimension of which varies between a region of minimum radial dimension and a region of maximum radial dimension, which are offset circumferentially to each other. Inlet means for introducing a buffer liquid into the annular space at or near to the region having a maximum radial dimension and outlet means for discharging said buffer liquid from said annular space at or near to the region having a minimum radial dimension are provided. At least one delivery-promoting recess is formed in a portion of the rotating member oriented axially to said annular space for promoting a flow of the buffer liquid along the annular space from the inlet to the outlet means and for receiving gas bubbles released from the buffer liquid when pressurized in the annular space.
