    摘要： An internally pressurised seal (10) assembly has a first seal ring (40) mounted in fixed axial and rotational relationship and sealed with respect to one of a pair of relatively rotatable components and a second seal ring (100) moveable axially but fixed rotationally and sealed with respect to the other of the pair of relatively rotatably components, the second seal ring is urged resiliently towards the first seal ring, so that a radial sealing face of the first seal ring engages a radial sealing face of the second seal ring, a process chamber (22) is formed at the inboard side of the seal rings, said process chamber opening to the outside of the seal rings, and a barrier chamber (16) is provided at the outboard side of the seal rings, the barrier chamber opening to the inside of the seal rings, the external circumferential surface of the seal rings are shielded from process fluid in the process chamber by shroud members (62) which ensure that heat transfer from the process fluid to the seal rings predominantly occurs at the outer regions of the seal rings adjacent the sealing faces, and a sleeve (70) is secured internally of each seal ring which ensure that heat transfer between the seal rings and a barrier fluid in the barrier chamber predominantly occurs at the radially extending surfaces of the seal rings adjacent the sealing faces.

    摘要： A seal ( 10, 1 2) having a mating ring ( 100, 100') mounted in fixed axial and rotational relationship with respect to a shaft ( 14) and a primary ring ( 120, 1 20') mounted in fixed rotational relationship but moveable axially with respect to a housing assembly ( 16); springs (136) being provided to urge the primary ring ( 120, 120') axially into sealing engagement with the mating ring ( 100, 100'), the mating ring ( 100, 100') being mounted with respect to said shaft ( 14) in abutment with a first radial face (44,62), characterised in that a circumferential surface of said mating ring ( 100, 100') is spaced radially from a circumferential surface on the shaft ( 14) and an annular helical spring element ( 104) is located, under radial compression, between said circumferential surfaces, the annular helical spring element ( 104) being formed from wire of elongate section, the axial width of the section being greater than the radial thickness.

    摘要： A fermentation apparatus (10) with a fermentation vessel (12) having a low speed stirrer, the stirrer comprising a shaft (14) entering the vessel through an aperture (16) in the bottom of the vessel, one or more stirring elements (18) being mounted on the shaft for rotation therewith within the vessel; a seal (20) being provided to seal the gap between the shaft and aperture, the seal being located in a cylindrical housing attached to the bottom of the vessel, the seal having first and second seal assemblies (30, 50) spaced axially of one another to define a chamber (64) therebetween, an inlet (66) opening into said chamber for connection of the chamber to a supply of processing gas, the first seal assembly (30) being located between the fermentation vessel and the chamber comprising a seat (32) mounted on the shaft for rotation therewith and a mating ring mounted (36) in fixed rotational relationship but moveably axially of the housing, a sealing face (44) of the mating ring being resiliently biased into engagement with a sealing face (42) of the seat, the sealing face of one of the mating ring or the seat having grooves (68) , which will provide hydrodynamic separation of the sealing faces upon rotation of the shaft .
