摘要： A shaft seal device comprises two mechanical seals for sealingly separating a sealed fluid region from an atmospheric region. A shaft is rotatable about an axis and extends through a casing from a sealed fluid region to an atmospheric region. The mechanical seals separate the sealed fluid region and the atmospheric region by a purge region formed between the mechanical seals. Each mechanical seal comprises a first seal ring fixed on the shaft and a second seal ring slidable in the axial direction and pressed against the first seal ring. The mechanical seal separating the sealed fluid region from the purge region is a contact type seal so that the fluid pressure of the sealed fluid region acts as a back pressure on the second seal ring. The mechanical seal separating the atmospheric region from the purge region is non-contact type seal so that the fluid pressure of the purge region acts as a back pressure on the second seal ring. The purge fluid region is charged with a gas such as nitrogen at a pressure lower than the pressure in the sealed fluid region.

摘要： A shaft sealing apparatus capable of preventing gases vaporized from a gas seal or purge fluid from leaking outside before a pressure switch operates due to a pressure rise resulting from a fluid leakage from a mechanical seal. The apparatus comprises a seal casing and a rotary shaft passing through the former and having a mechanical seal A and a dry gas seal B mounted thereon in line with each other to provide purge fluid areas C therebetween. With this arrangement, a purge fluid is supplied to one of the purge fluid areas through a supply line having an orifice OA and the supplied purge fluid and a leaked part of a target fluid to be sealed are released outside from the other purge fluid area through a relief line having an orifice OB. The relief line is provided with a bypass line with an electromagnetic valve and a pressure switch and bypassing the orifice OB. In this case, the purge fluid supply pressure P1, the preset pressure P2 between the orifices OA and OB, the pressure P3 in the area from the orifice OB to outside and the pressure switch operating pressure Ps satisfy the relationships of P1>Ps>P2>P3.

摘要： A static pressure-type generating non-contact gas seal in which a diameter d2 of a second outer circumferential portion (42) of a stationary seal ring (4) in contact with a second O-ring (62) is made smaller than the diameter d1 of a first outer circumferential portion (41) of the stationary seal ring (4) in contact with a first O-ring (62). Because of d1>d2, the pressure of a seal gas (8) led to a first closed space (71) produces a force thrusting the stationary seal ring (4) toward a rotary seal ring (2). A second closed space (72) communicates with an inside region (F) through a back pressure lead-in path (45). The inside gas pressure in the second closed space (72) acts as back pressure on the stationary seal ring (4). The groove width b of static pressure generating grooves (9) formed on the seal end face of the stationary seal ring (4) is decided so that a ratio of the groove width d to the radial width, that is, the seal face width B of the stationary seal ring end face (40), i.e. b/B, is 0.05.ltoreq.b/B.ltoreq.0.03. The radial distance Bo from the outer edge of the seal end face (40) of the stationary seal ring to the static pressure generating groove (9) or the radial distance Bi from the inner edge of the seal end face (40) of the stationary seal ring to the static pressure generating groove (9) are selected so that 0.3 B.ltoreq.Bo.ltoreq.0.7 B-b or 0.3 B.ltoreq.Bi.ltoreq.0.7 B-b is achieved, provided that B-b=Bo+Bi. Groove depth L of the static pressure generating groove (9) is 0.3 to 1.0 mm. The pressure of the seal gas (8) led to the static pressure generating grooves (9) is 0.5 to 1.5 bar higher than the pressure in inside region (F). It is also designed so that the balance ratio K is 0.8.ltoreq.K.ltoreq.0.9, in which the balance ratio K is given by the equation:K=((D2).sup.2 -(Dm).sup.2)/((D2).sup.2 -(D1).sup.2),being defined by the diameter Dm of the inner cylinder portion (31) of the seal casing at the place where the inner circumferential portion of the third O-ring (63) comes in contact and the inside and outside diameters D1 and D2 of the seal ring end faces (20, 40).

摘要： A non-contact-type mechanical seal that keeps a rotary seal ring 6 from vibrating in what is called a pneumatic hammer fashion. For this purpose, an annular space 23 is formed between an outer circumferential surface 21a of the rotary seal ring 6 and an inner circumferential surface 13a of a holder portion 13 of a spring retainer 5. The annular space 23 is sealed by a pair of O rings 22, 22. In addition, seal gas leading passages 24 are provided in the rotary seal ring 6 through which spaces between seal end faces 3a, 6a communicate with the annular space 23. Seal gas 8 is supplied to static pressure generating grooves 15, and led into the annular space 23 through seal gas leading passages 24. The seal gas presses O rings 22, 22 against the outer circumferential surfaces of the rotary seal ring 6 and the inner circumferential surface of the holder portion 13 of the spring retainer 5, thereby firmly holding the rotary seal ring 6.

摘要： A stationary sealing ring (6) surrounds a rotatable shaft (2) and is fitted to, and held by, a cylindrical guide (1a) of a seal case (1). An extremely small clearance is provided between the outer peripheral surface (6b) of the stationary sealing ring and the inner peripheral surface (1c) of the guide. This small clearance prevents radial displacement of the ring but allows the ring to move in the axial direction and permits the passage of a fluid. Because the sealing ring is held without the use of a holding ring or an O-ring, the concentricity and parallelism of the stationary sealing ring to a rotary sealing ring (3) can be continuously maintained despite pressure fluctuations. Clearance between the stationary sealing ring and a holding ring (4) is maintained by an O-ring (9) held in an annular dovetail groove (10) formed in a surface (4c) of the holding ring facing the stationary sealing ring. The O-ring serves as a strain isolator which prevents the transmission of thermal and pressure strains between the holding ring and the stationary sealing ring.

摘要： A non-contacting shaft sealing device in which an even-number of dynamic pressure generating groove groups are arranged in the peripheral direction thereof on a sealing end face of the seal case side or a sealing end face of the rotary shaft side. Each dynamic pressure generating groove group is composed of one or plural shallow L-shaped grooves of a specific groove width comprising a fluid lead-in part extending in the radial direction from a peripheral edge of high pressure side of said sealing end face and a dynamic pressure generating part extending in the peripheral direction from the end portion thereof. When the dynamic pressure generating groove group is composed of plural L-shaped grooves, those L-shaped grooves are arranged close to each other at an equal pitch without crossing each other such that the end portion of each dynamic pressure generating part is positioned on a fourth sealing end face diametral line. Each dynamic pressure generating groove group is symmetrical with respect to each of the adjacent dynamic pressure generating groove groups on both sides thereof around a first sealing end face diametral line passing between those fluid lead-in parts (between the fluid lead-in parts of the outermost side when the dynamic pressure generating groove group is composed of a plurality of the L-shaped grooves) or a second sealing end face diametral line passing between those dynamic pressure generating groove groups.

摘要： A seal device of the non-contact type having seal faces formed by those end faces of a rotating seal ring and a stationary ring which are perpendicular to axes of the two rings, and also having dynamic pressure generating grooves formed in one of the seal faces at a certain interval in the circumferential direction of the seal face each groove having a first spiral groove portion and a second terminal portion being formed continuous from the front end of each of the first spiral groove portions, extending along the circumferential direction of the seal face but across its corresponding first spiral groove portion, and provided with a closed front end. The seal device can be used at high speed and under high pressure and it can correct the tilting of its seal faces, which is caused by pressure and heat added, to prevent them from being contacted with each other. Even when the difference of pressures added to them changes, the seal device can keep them parallel to each other to reduce the amount of liquid leaked to a greater extent.
