摘要： The mechanical seal (3) includes: a rotary side sliding ring (32) which is supported by the large diameter side outer circumferential face (23) of the annular step section (21) of the rotary shaft (2) via the rotary side O-ring (37) and press-fitted into the annular step section (21) by gas pressure in the device; and an unturnable stationary side sliding ring (31) which is fixed onto the seal housing (1) side via the stationary side O-ring (33) being capable of moving in the axial direction and being able to come into close contact with the sliding protrusion (323) of the rotary side sliding ring (32) due to the spring (36) so that the airtightly sealed sliding face S is formed. The rotary side sliding ring (32) is made of self-lubrication sliding material, and the stationary side sliding ring (31) is made of sliding material, the Young's modulus of which is higher than that of the self-lubrication sliding material. A deforming force given to the rotary side sliding ring (32) in the leaning direction caused by differential pressure between the high gas pressure and the atmospheric pressure outside the device is canceled by a deforming force caused by a component in the axial direction of the differential pressure acting on the annular step section (21) of the rotary shaft (2) in the pressing direction.

摘要： A pumping ring 46 producing an axial flow of sealed flow is secured to a rotary shaft 6 at an axial position different from a rotary ring 56 so that the sealed fluid positioned in the sealed space 33 flows along the axial direction of the rotary shaft 6. A discharge hole 14 is formed on an inner circumferential surface of a seal cover 8 positioned in the downstream side of the axial flow of the sealed fluid resulting from a rotation of the pumping ring 46. An inflow hole 15 is formed in the upstream side of the axial flow of the sealed fluid resulting from the rotation of the pumping ring 46, so that the sealed fluid discharged from the discharge hole 14 returns to the inside of the sealed space from the inflow hole 15. On the inner circumferential surface of the seal cover 8 provided with the discharge hole 14, a baffle member 18 is provided so that it protrudes radially inward in order to block the flow of the sealed fluid along the rotating direction of a retainer 52 and orient the sealed fluid toward the discharge hole 14.

摘要： A pair of primary and secondary mechanical seals are arranged tandem in an axial direction around a rotating shaft in a space between the rotating shaft and a housing having a shaft sealing part. The center or intermediate liquid is sealed into a center room or intermediate chamber between both mechanical seals. The center liquid has an amount that is less than the volume of the center room and enough to soak one part of rotating elements of the secondary mechanical seal. The gas vent line is provided with the housing of the shaft sealing part. The gas vent line faces and opens to the center room. The baffle plate is provided with the housing of the shaft sealing part. The baffle plate intersects a circumferential direction of the center room. Thus, when rotating the rotating shaft, the center liquid is stirred and scattered by collision with the baffle plate to lubricate the sealed slide surface. The vaporized gas from the sealed liquid, which is leaked from the primary mechanical seal to the center room, does not collect in the inner circumferential part of the center room. It does not form a gas zone. It is discharged from the gas vent line.

摘要： A seal contact surface of a seal lip member and a protruding lip member of an end face seal are separated from each other and frictional heat generated at the seal lip member due to sliding motion is prevented from being transferred to the end face seal for softening the material, thus the seal capability is improved. A protruding lip member (3) provides a seal by making an angle to a seal surface (11B) of a seal ring (11) in radially outward a direction and a lip portion (15A) of a seal lip member (15) is disposed inside an inner diameter surface (11A) of the seal ring (11) for effecting a seal against a sealing object fluid.
