摘要： A mechanical seal for providing fluid sealing between a housing and a rotatable shaft includes a first seal ring having a first seal face and a second seal ring having a second seal face. The first seal face further has a first portion and a second portion and the seal faces of the first and second seal rings are opposed to each other when assembled. The first seal ring or the second seal ring is adapted to rotate with the rotatable shaft, and the other seal ring is restrained from rotating. The seal faces are configured to produce a primarily hydrostatic fluid force between at least a portion of the first portion of the first seal face and at least a portion of the second seal face. In addition, the seal faces are configured to produce a hydrodynamic fluid force and a hydrostatic fluid force between at least a portion of the second portion of the first seal face and at least a portion of the second seal face.

摘要： A mechanical seal for providing fluid sealing between a housing and a rotatable shaft includes a gland assembly, a secondary sealing assembly, and first and second seal rings each having a seal face. The secondary sealing assembly provides fluid sealing between the seal rings and the gland assembly. The secondary sealing assembly includes a compression member having a front surface and a rear surface, a resilient member positioned between the rear surface of the compression member and the inner surface of the gland assembly for axially biasing said compression plate, and a sealing member interposed between the front surface of the compression member and the rear surface of the first seal ring. Either the rear surface of the first seal ring or the front surface of the compression member is configured to impart an axial and a radial sealing force on said sealing member to place the sealing member into sealing engagement with the first seal ring and the inner surface of the gland assembly.

摘要： A split mechanical face seal that provides fluid sealing between a housing and a rotating shaft includes first and second seal rings each having at least two seal ring segments and a radially extending seal surface. The seal ring surfaces of the seal rings are opposed to one another. One of the seal rings is connected to the rotating shaft to rotate therewith, while the other seal ring is connected to the housing. The split seal also includes a mechanism for introducing a fluid to the seal surfaces of the first and second seal rings. The seal further is provided with a system for maintaining co-planar alignment of the seal faces.

The seal ring faces of the seal rings are opposed to one another. One of the seal rings is connected to the rotating shaft to rotate therewith, while the other seal ring is connected to the housing. The split seal also includes a continuous, circumferential groove formed in the seal face of the first seal ring for introducing a fluid to the seal faces of the first and second seal rings to establish a seal therebetween. A split support member having at least two support segments for coupling the first seal ring to the housing or the rotating shaft is also provided. The split face seal is operable as both a contacting and a non-contacting mechanical face seal.

摘要： A split mechanical face seat that provides fluid sealing between a housing and a rotating shaft includes first and second seal rings each having at least two seal ring segments and a radially extending seal surface. The seal ring surfaces of the seal rings are opposed to one another. One of the seal rings is connected to the rotating shaft to rotate therewith, while the other seal ring is connected to the housing. The split seal also includes a mechanism for introducing a fluid to the seal surfaces of the first and second seal rings. The seal further is provided with a system for fluidly retaining together the seal ring segments of one of the seal rings in a sealing relationship during a negative pressure condition.
