Appl. No.:

10/889146

International Classification:

F04B 17/00
F16C 35/00

US Classification:

417407, 41742312, 41742313, 384462, 384523

Abstract:

Portions of the drive system for a piece of rotating equipment are pre-assembled into a subassembly. The subassembly can be held together by a carrier that is fabricated to accept the components in a proper alignment so that the carrier can be installed as a unit. In one embodiment, the carrier becomes a gearbox housing component that is installed, saving the need for individual component alignment. This modular approach allows an assembly having a single part number to apply to a given compressor unit and further allows standardization of air ends of compressors with specific impellers and inlets added to meet requirements of a specific application.

US Classification:

4151221, 415206, 4152141, 415912, 415915

Abstract:

The volute is cast integrally with the gearbox base to allow closer radial tolerances to be used to improve efficiency. In the preferred embodiment, compressors for multi-stage compression are assembled with intercoolers and the integral volute is cast together with the impeller housing and the lower gearbox housing and the associated intercooler. Efficiency increases of 2% or more are achievable. In multistage applications, efficiency gains in the early stages are compounded in each subsequent stage. Speed changes that change center distance between bull gear and pinion are accommodated by an offset opening in the inlet and diffuser that can line up with the impeller shaft as well as an offset opening in the fluid seal despite a pinion gear change, by reorientation and remounting of those parts.

US Classification:

4152083, 415148, 4152092, 4152093, 4152111, 4152112

Abstract:

A system, in certain embodiments, includes a centrifugal compressor diffuser that includes an elliptical plate including multiple vane receptacles disposed about an axis of the plate and multiple detachable vanes attached to the plate. Each vane receptacle includes a first two dimensional (2D) projection along a plane of the elliptical plate and each detachable vane includes a second two dimensional (2D) projection along a base portion of the vane, where each detachable vane is disposed in a respective vane receptacle with the first and second 2D projections blocking movement of the detachable vane in at least a first axial direction relative to the elliptical plate. In certain embodiments, the first and second 2D projections may include a first tab to fit in a recess between a pair of second tabs, respectively, or vice versa. However, in other embodiments, the first and second 2D projections may include alternative mating surfaces.

International Classification:

F01D 15/08

US Classification:

4151242

Abstract:

Provided in some embodiments is a gas compression system that includes a gas compressor having a drive shaft, an impeller drive shaft magnetically coupled to the drive shaft, and a shroud disposed between the drive shaft and the impeller drive shaft. In other embodiments provided is method that includes magnetically coupling a first drive shaft to a second drive shaft, receiving a rotational torque at the first drive shaft, transmitting the rotational torque from the first drive shaft to the second drive shaft via the magnetic coupling, and rotating a gas compressor impeller coupled to the second drive shaft.
