摘要： A shaft seal device is fixed to a container that separates a high-pressure fluid and a low-pressure fluid from each other, and seals a shaft-penetrated portion of the container through which a rotational shaft extends. This shaft seal device includes: a seal casing having a through-hole through which the rotational shaft extends, the seal casing having a seal chamber which communicates with the through-hole and into which the high-pressure fluid flows; and a disk-shaped seal body which is housed in the seal chamber, the seal body being rotatable together with the rotational shaft and having an annular surface perpendicular to an axis of the rotational shaft. An inner surface of the seal casing, which faces the annular surface of the seal body and defines the seal chamber, is a flat surface perpendicular to the axis of the rotational shaft.

摘要： The axial reaction force generated by a subsea pump or compressor is partially counteracted by a pressure differential in a barrier fluid across a thrust element. The pressure differential is created using impellers or other structures on the thrust element that increases the barrier fluid pressure on one side of the thrust element when the main shaft of the pump or compressor is rotated. The pressure differential across the thrust element partially offloads the bearing surface of the thrust element.

摘要： A device which is used to guide at least two flow media having different pressures with a shaft or similar force-transmitting element, and a pressure insulating element such as a housing surrounding the shaft or similar. Areas arranged next to each other in the direction of the axis are determined between the force-transmitting element and the pressure-insulating element by sealing elements; at least one of the preferably magnetofluidic sealing elements is leakage-free, and two areas for fluids (A, B) having different pressures flank an area for an auxiliary liquid (H), whereby said area is subdivided by a device into two partial areas for two different pressure areas. A conveying medium is allocated to the area at high pressure and ambient air is allocated to the area at low pressure. The auxiliary liquid (H) is a carrier oil of the magnetofluid, optionally a silicon oil, allocated to the sealing element.
