摘要： A slide ring seal for sealing a gap between a rotatable and non-rotatable machine part. The seal comprises at least one static seal ring to be attached to the non-rotatable machine part and provided with a slide ring and at least one counter ring to be fastened to the rotatable machine part and provided with a slide ring. The static seal ring and the counter ring are thereby arranged to be fastened in such a way that the slide surfaces of the slide rings are tightly pressed against each other. In order to simplify the structure of the seal the counter ring and the static seal ring are mutually replaceable sealing modules.

摘要： A shaft seal assembly for an apparatus for continuous processing of very viscous media, in particular for producing high molecular weight polymers, having parallel shafts (1) carrying at least two cooperating processing tools (3), with which shafts feed and removal devices for the product to be processed and one reaction chamber (4), which can be subjected to a vacuum, are associated, has sealing means having at least one slide ring seal (46, 55), by which means the reaction chamber is sealed off, in the vicinity of the shaft ducting devices, from a confining-liquid chamber (11) located on the outside and surrounding the shaft ends, which chamber contains confining liquid. To avoid the entry of confining liquid into the reaction chamber and to improve the sealing action, the arrangement is selected such that on the side oriented toward the reaction chamber, adjoining the sealing means, each shaft (1) is surrounded by an inert gas cushion, which has a higher pressure than the confining liquid and is defined, sealed off from the reaction chamber (4), by means of housing parts (81) surrounding the shafts over a portion of their length as well as by means of the product to be processed, which surrounds the shafts and is under pressure.

摘要： The present invention is directed to a grit exclusion and oil retention seal for use in extremely hostile environments. These environments include, but are not limited to sealing oil within cavities forming parts of earth drilling bits and the like. Seals such as these, include the ability to seal oil within a cavity in a reliable manner even under extreme conditions of vibration, mechanical shock, and the presence of grit, sand, water, dirt and mixtures thereof. In order to function properly in this environment, the seal must also provide a certain amount of axial end play so that relative movement of the sealed parts will not permit the seal to leak.In this connection, a heavy duty seal of the type with which the invention is concerned must provide not only a primary or relatively moveable seal, but also a secondary seal. The seal assembly must include means for transmitting torque from the housing or carrier to the primary seal rings. Means must be present for applying and maintaining an axial end face load of the proper range.

摘要： A liquid sealed shaft seal for a rotatable shaft comprises a housing disposed around the shaft and defining a seal chamber which can be supplied with sealing liquid. A seal disc is fixed to the shaft and extends into the chamber. An axially movable piston is mounted on the housing for axial movement toward and away from a side face of the seal disc. The piston is provided with a slide ring which engages the slide disc when the shaft is at a standstill and which, through a circumferentially induced increase in pressure for the sealing liquid in the chamber, is moved axially away from the disc when the shaft and disc rotate. A resilient bellows is connected between the piston and the housing for biasing the piston toward the disc.

摘要： A mechanical seal mounting assembly for a centrifugal high solids concentration slurry pump is disclosed. A rotating seal ring adapter is secured to the pump's impeller drive shaft for rotation with the shaft. A stationary seal ring adapter is secured to a first end of a seal carrier which extends through the pump's back plate. A split gland ring is attached to a second end of the seal carrier and is supported by gland nuts threadedly carried on gland bolts. The gland bolts are attached to a bearing assembly for the pump shaft. Axial movement of the pump shaft to effect impeller clearance seal adjustment is possible without disturbing the mechanical seal adjustment. An O-ring is interposed between the pump back plate and the seal carrier and is held in place by an O-ring retainer secured to the back plate of the pump.

摘要： A rotary seal interposed between an axially and rotatably movable shaft and stationary housing, the seal having a flexible annular boot or diaphragm mounted in surrounding relation to the shaft and terminating in an outer peripheral margin which abuts a seal ring, the seal ring having a tapered face engaging a sloped surface on the outer stationary housing. A spring-loaded member urges the seal ring into firm engagement with the housing portion, and the outer free end of the boot is free to be radially displaced along its interface with the seal ring while urging the seal ring in an axial direction firmly into engagement with the sloped portion on the stationary housing.
