The invention relates to a static seal the clearance of which may be adjusted while the pump is running. Especially the invention discusses the novel structure of such a static seal. A characterizing feature of a centrifugal pump comprising a pump housing ( | 05-07-2009 |
20100316494 | TURBINE HOUSING FOR GAS TURBOCHARGERS - A turbine housing for exhaust gas turbochargers includes an outlet pipe and an external housing connected therewith. A rotor housing is disposed in the external housing and has a pipe-shaped neck operably coupled with the outlet pipe and axially displaceable relative to the same. A separate sealing ring is positioned operably between the neck and the outlet pipe, supported by the outlet pipe, and has an inwardly turned sealing portion sealingly and slidingly engaging the neck to form a secure gas seal therebetween. | 12-16-2010 |
20110103949 | Extraction Cavity Wing Seal - The present application provides a pressure containing casing. The pressure containing casing may include a first extraction cavity, a second extraction cavity, an interface between the first extraction cavity and the second extraction cavity, and a wing seal positioned within the interface. | 05-05-2011 |
20110182729 | LEAF SEALS - A leaf seal | 07-28-2011 |
20120099986 | LIQUID SEAL, SHAFT SEAL APPARATUS AND PUMP APPARATUS USING THE SAME - A liquid seal has an annular lip portion and an annular fixing portion to be fixed to an inner peripheral surface of a shaft hole, in which the lip portion is connected to the fixing portion and is provided so that a tip thereof is extended in an axial direction, a spring pressing a seal lip against an outer periphery of the rotation shaft is fitted onto the lip portion. The seal lip forms a mountain shape in which an edge of the apex in the cross section, which is cut along a plane passing through a center axis of the seal, protrudes to the inner diameter side, and the pressure center of the seal lip due to the spring is disposed between the tip side of the lip portion further than the edge of the apex of the mountain of the seal lip in the axial direction. | 04-26-2012 |
20120134799 | Adjustable mechanical seal - A mechanical seal is disclosed that has first and second sealing faces that are urged into contact to form a seal therebetween. One sealing face is mounted on a rotatable portion of the seal and the second sealing face is mounted on a support assembly. The joint further comprises a joint permitting rotary movement between the support assembly and a stationary portion of the seal to allow adjustment of the potion of the rotatable portion relative to the stationary portion without affecting the alignment of the first and second sealing faces. | 05-31-2012 |
20120315138 | COMPLIANT PLATE SEAL ASSEMBLY FOR A TURBO MACHINE - A seal assembly for a turbo machine is provided. The turbo machine includes a rotary component and a stationary component. The seal assembly is disposed between the rotary component and the stationary component. The seal assembly is configured to provide a sealing between a high pressure area and a low pressure area of the turbo machine. The seal assembly includes a plurality of compliant plates coupled circumferentially along the stationary component. Each of the compliant plate includes a tip disposed facing the rotary component. A tip slot is provided on the tip of the compliant plates, wherein the tip slots is provided at the portion of the tip proximate the high pressure area. The compliant plates further include a plate slot extending from the stationary component towards the tip. An annular resistance member coupled to the stationary component is disposed in the plate slot in the compliant plates. | 12-13-2012 |
20130251523 | Intershaft Seal with Centrifugal Compensation - A segmented intershaft seal assembly for use between inner and outer shafts within a turbine engine is presented. The intershaft seal assembly includes annular end rings, an annular seal element with an inverted “T”-shaped cross section, at least one resilient element, an annular spacer ring, carriers, counterweights, and hydrodynamic grooves. The intershaft seal assembly is secured to the inner shaft. The resilient element(s) biases seal segments away from the inner shaft toward the outer shaft. The counterweights are disposed about the seal segments and substantially negate forces imposed by the seal segments outward toward the outer shaft. The hydrodynamic grooves are disposed along an inner annular surface of the outer shaft and direct fluid onto an outer surface along the seal segments when the outer shaft rotates. The hydrodynamic grooves form a thin-film layer and non-contact seal that separates the seal segments from the outer shaft which otherwise provide a contact-type seal. | 09-26-2013 |
20140241877 | SHAFT SEALING DEVICE AND ROTATING MACHINE COMPRISING SAME - A shaft sealing device is provided in an annular space between a rotor and a stator surrounding an outer periphery of the rotor, and divides the annular space in the direction of an axis of the rotor into a high-pressure region and a low-pressure region. The shaft sealing device includes a seal body obtained by stacking a plurality of thin plate sealing pieces in a circumferential direction of the rotor; and a high-pressure side plate that extends from the stator toward the radial inner side so as to run along the high-pressure side of the seal body, and is segmented into a plurality of portions in the circumferential direction, and includes a rigidity imparting member configured to impart rigidity in the direction of the axis to a portion of the surface of the high-pressure side plate that faces the high-pressure region. | 08-28-2014 |
20140341733 | BI-DIRECTIONAL SHAFT SEAL - A non-contacting seal is provided, including a first sealing face formed on an end of a primary ring and a second sealing face formed on an end of a mating ring. Grooves may be formed in at least one of the first and second sealing faces, such that the grooves extend from one edge of the respective sealing face to an intermediate radius of the respective sealing face. At least one groove may include an entrance edge along the one edge of the respective sealing face and a dam wall opposite the entrance edge. The at least one groove may also include two symmetric side walls extending from the entrance edge to the dam wall. The two symmetric side walls may include a first convex curve extending from the entrance edge to a transition point and a second concave curve extending from the transition point to the dam wall. | 11-20-2014 |
