摘要： A sleeve valve for fluid flow between a hydrocarbon reservoir and a well including a fixed outer sleeve with openings and a movable inner sleeve with openings which can be aligned and misaligned with the outer sleeve openings in order to admit or shut off the fluid flow. The outer sleeve opening is provided with a movable sealing element that has a through-going radial opening adapted to rest around the opening in the inner sleeve, and a tension element presses the sealing element against the inner sleeve. A portion of the side face of the sealing element forms a pressure face which under the effect of pressure in a pressure chamber presses the sealing element against the inner sleeve. The pressure chamber is via at least one connection connected to at least one pressure source whereby pressure propagation from the pressure source to the pressure chamber causes the sealing element to be pressed even more against the inner sleeve.

摘要： A sealing mechanism comprises a support member forming part of the semiconductor producing apparatus which has a vacuum chamber, a rotation shaft rotatably received in the support member, and at least three seal rings axially spaced apart from each other between the support member and the rotation shaft to form a first fluid chamber close to the atmosphere and a second fluid chamber close to the vacuum chamber. The first fluid chamber is vacuumized to have a first pressure, and the second fluid chamber is also vacuumized to have a second pressure which is lower than the first pressure. The first and second fluid chambers work together to enhance the sealing performance of the sealing mechanism.

摘要： A seal gas pressure booster system for use with a gas compressor, particularly of the type used for boosting pressure in gas transmission, process or utility industries and which contains pressure about the shaft/casing interface with the use of dry gas seals. Seal supply gas is supplied from the discharge side of the compressor. During normal operation, sufficient head across the compressor exists to supply the necessary flow of seal supply gas against the restrictions provided by the filters, interconnections and components in the seal gas supply system. During startup, or during modes of operation where sufficient head across the compressor does not exist, the pressure booster system increases the pressure of a stream of compressor discharge gas to provide the necessary pressure differential to supply the dry gas seal with a continuous flow of clean, filtered gas.

摘要： A means of sealing a rotating shaft against high fluid pressure with low friction torques, low leakage and low wear. This accomplished by use of sealing assembly comprising a sliding and a floating seal assembly separated by a lubricant filled chamber. The sliding seal is exposed to the high pressure environment which is kept isolated from the drive means by the chamber. Thus, the high pressure environment leaks into the chamber rather than the environment of the drive means and the non-harmful lubricant leaks slowly into the drive means environment.

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 multi-stage centrifugal pump is described having a linear series of impellets mounted on a common impeller shaft, with axial thrusts imparted to the shaft by the impellets being balanced by a sealed high-pressure thrust bearing assembly secured to the pump casing. The pump is particularly suitable for using in pumping an abrasive fluid. A clean lubricating oil is supplied to the thrust bearing assembly at a pressure slightly greater than that of the abrasive pumped fluid, to ensure that the fluid that migrates across a mechanical seal interposed between the impeller assembly and the thrust bearing assembly is the lubricating oil, not the abrasive pumped fluid. High pressure differentials across a breakdown bushing involving the abrasive pumped fluid, and a resulting wear and erosion of pump components, thereby are avoided.

摘要： The shaft (16) goes through a hole in a wall (10). A bushing (26) is attached to the wall and carries a first gasket (28) adjacent to the wall and sealing against the shaft (16) and a lip seal (32) at a distance from the first gasket so that a toroidal chamber (34) is defined between the first gasket, the web, the bushing and the shaft. An inlet passage (44), preferably bored in the body of the bushing, connects said toroidal chamber (34) with a source of pressurized water, and an outlet passage (48), also preferably bored in the body of the bushing, drains the water from the toroidal chamber (34).

摘要： A driving device comprises a first cover, a second cover telescopically engaging with the first cover, and a third cover surrounding the first and second covers. Part of a driving member for moving the second cover in relation to the first cover is arranged in a first space defined in the first cover. The first space is supplied with nitrogen, and pressure in the space is kept at a positive value. Gas is fed into and exhausted from a second space defined between the first and second covers, in accordance with a change in the volume thereof, whereby pressure in the second space is kept at a substantially constant value. Gas contained in a third space defined between the third cover and the first and second covers is exhausted, and pressure in the third space is kept at a negative value. Thus, the first space is completely isolated from a space around the driving device.

摘要： In a shaft seal for hydrogen-cooled, turbo-generators, the operating requirements for a minimum gas-side leakage flow without secondary liquid circuit and cooling of the entire axial ring length are fulfilled either with choke elements (8) or with an inner transfer of sealing liquid from the gas side (G) to the air side (L) so that this shaft seal can function with a single sealing liquid circuit as a so-called single-circuit seal in parameter areas which are at present still the preserve of a multi-circuit seal.
