    摘要： A rotary mechanical face seal includes first and second seal face members (10, 14), the sealing face (13) of one seal face member (14) being urged into engagement with the sealing face (16) of the other seal face member (10), said seal face members (10, 14) being such that when subjected to temperature gradients due to the generation of heat at the sealing faces (13, 16) the sealing faces (13, 16) will remain substantially parallel in spite of any thermal distortion of the seal face members (10, 14).

    摘要： A mechanical face seal comprises a first seal face member l2 associated in fixed relationship and sealed with respect to one component l0; a second seal face member l8 associated in fixed rotational relationship and sealed with respect to a second component ll and a third seal face member 2l interposed between the first and second seal face members l2, l8. Spring means 20 is provided to urge the second seal face member l8 towards the first seal face member l2 and maintain the first, second and third seal face members l2, l8, 2l in sealing engagement. The sealing faces 22, 23, 24, 25 of the first, second and third seal face members l2, l8, 2l are inclined, so that the first and second seal face members l2 and l8 impose a radial load on the third seal face member 2l. Two such seal assemblies may be provided co-axially of one another to provide a double seal.

    摘要： A gas tight seal comprises a retaining means (5) adapted to be mounted on a partition (l) to surround a rotary component (l0) where it penetrates the partition (l). A pair of annular floating members (3) are located in axially spaced apart relationship by said retaining means (5). Sealing means (9; 20) are provided between the inner periphery of the floating members (3) and the rotary component (l0), these sealing means (9; 20) being arranged to make sealing engagement with the rotary component (l0) when liquid under pressure is introduced into the space (8) between the floating members (3).

    摘要： A dry gas mechanical seal system (200) configured to inhibit the emission of process gas. The mechanical seal system having tandem first and second stage seals, and a single separation gas supply subsystem configured to direct a supply of separation gas from an inlet (250) through interfacing portions (260, 262) of the first stage seal into a process cavity (206) and from the inlet through the interfacing portions (268, 270) of the second stage seal and out through an outlet (280) to the atmosphere, thereby inhibiting the emission of process gas between a compressor housing (204) and a rotating compressor shaft (202).
