Abstract:
A cooling system for a motor-compressor and a method for cooling the motor-compressor are provided. The cooling system may include a discharge assembly having a hub portion disposed radially outward of a rotary shaft of the motor-compressor. A plurality of arms may be fluidly coupled with and may extend generally tangential from the hub portion of the discharge assembly. The hub portion may define an annular volume fluidly coupled with the plurality of arms. The cooling system may also include a blower impeller disposed in the annular volume and coupled with the rotary shaft. The blower impeller may be configured to rotate with the rotary shaft and draw a cooling fluid into the discharge assembly.
Abstract:
A "bolt on" static separator is disclosed for use in conjunction with a rotating separator to handle higher liquid volumes that are not able to be effectively separated by the rotating separator alone. The static separator may be positioned upstream of the rotating separator, generally right in front of the rotating separator, i.e., immediately ahead of the inlet to the rotating separator and generally attached directly to the front end of the rotary separator. The static separator may include a significant change in flow path direction that is sufficient to cause coarse fluid separation. The output of the static separator is in communication with the input of the rotating separator. Additionally, the drain of the static separator is in communication with the drain of the rotating separator and is at the same pressure.
Abstract:
An energy conversion system including an annular member disposed around a shaft and at least partially defining a first radial flow passage that is fluidly coupled to a wave chamber and a second radial flow passage that is fluidly coupled to a port; a first plurality of nozzle vanes extending at least partially through the first radial flow passage, and configured to impart a first exit swirl angle in a fluid; a turbine wheel coupled to the shaft, disposed radially between the shaft and the annular member, defining an axial flow passage that is fluidly coupled to the first and second radial flow passages, and including a first plurality of impulse blades; and a second plurality of nozzle vanes disposed around the shaft, extending at least partially through the second radial flow passage, and configured to impart a second exit swirl angle in the fluid.
Abstract:
An energy conversion system, including a wave chamber, and a turbine wheel coupled to a shaft and fluidly coupled with the wave chamber. The energy conversion system may also include a first radial flow passage fluidly coupled with the wave chamber and the turbine wheel, and first vanes disposed at least partially in the first radial flow passage, each of the first vanes being compliantly mounted and pivotal between first and second positions, the first vanes being configured to allow a motive fluid to flow in a first radial direction through the first radial flow passage when the first vanes are in the first position, and the first vanes being configured to substantially prevent the motive fluid from flowing through the first radial flow passage in a second radial direction when the second vanes are in the second position.
Abstract:
An auxiliary bearing including a bearing mount disposed circumferentially about a shaft. A support wall may extend radially inward from the bearing mount, and the support wall may define a first annular cavity. An outer race may be coupled to a radially inner surface of the support wall. An inner race may be rotatably coupled to the outer race, and a plurality of rolling elements may be disposed between the inner and outer races. A pool of lubricant may be disposed within the first annular cavity, and at least a lowermost one of the plurality of rolling elements may be at least partially disposed in the pool.
Abstract:
An auxiliary bearing system for supporting a rotating shaft including a first auxiliary bearing coupled to the rotating shaft. A first inertia ring is coupled to and circumscribes the first auxiliary bearing. A second inertia ring circumscribes the first inertia ring. A radial clearance is defined between the first and second inertia rings when the rotating shaft is supported by a primary bearing system, and the first inertia ring engages the second inertia ring when the rotating shaft is not supported by the primary bearing system. A second auxiliary bearing is engaged with an outer surface of the second inertia ring.
Abstract:
A closure device for a compressor having at least one access opening, wherein the closure device includes a plug portion disposeable at least partially within and configured to substantially obstruct the at least one access opening, a head portion having a shoulder surface extending generally radially outwardly with respect to the plug portion, wherein the head portion is generally disposeable against an inner surface of the compressor and configured to maintain the plug portion disposed within the at least one access opening during compressor operation, and a retainer member having a bracket engageable with an outer surface of the compressor and a threaded rod extending between the bracket and the plug portion, wherein the retainer member is configured to retain the plug portion disposed within the at least one access opening.
Abstract:
A support structure for rotating machinery is provided. The support structure may include a first main hollow support member and a second main hollow support member, each having a longitudinal axis and a square cross-section. The second main hollow support member may be coupled with the first main hollow support member such that the longitudinal axis of the second main hollow support member is substantially perpendicular to the longitudinal axis of the first main hollow support member. The support structure may also include a plurality of secondary support members, each coupled with the first main hollow support member, the second main hollow support member, or the first main hollow support member and the second main hollow support member, and configured to support the rotating machinery disposed on the support structure.
