20080273991 | AIR COOLED PACKAGED MULTI-STAGE CENTRIFUGAL COMPRESSOR METHOD - Provided is a method including routing a compressed gas from a centrifugal gas compressor through at least one of a plurality of air coolers, and directing air flow through the plurality of air coolers, wherein the plurality of air coolers are arranged adjacent to one another in a single plane that is transverse to the air flow. Further provided is a method including removing tube cores from a cooler chamber of a liquid cooler of a centrifugal gas compressor, coupling a chamber port of the cooler chamber to a first port of an air cooler, and coupling a second port of the air cooler to a compressor port of a stage of the centrifugal gas compressor. | 11-06-2008 |
20090014244 | INTEGRATED ROTARY VALVE - A system in some embodiments includes a machine block comprising features configured to support moving machine components within a lubricating fluid, wherein the machine block includes an integral valve block configured to route the lubricating fluid through a first filter without a second filter and configured to route the lubricating fluid through the second filter without the first filter. Further embodiments include a method that includes switching circulation of a lubricant between a first filter and a second filter in response to an angular position of a valve disposed in a valve block integral to a machine block having moving components lubricated by the lubricant | 01-15-2009 |
20100098534 | INTEGRAL SCROLL AND GEARBOX FOR A COMPRESSOR WITH SPEED CHANGE OPTION - 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. | 04-22-2010 |
20110052111 | MODULAR ROTOR ASSEMBLY - 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 the preferred embodiment the carrier becomes a gearbox housing component that is installed saving the need for individual component alignment. Using the modular approach. The 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. | 03-03-2011 |
20110056769 | INTEGRATED LUBRICATION MODULE FOR COMPRESSORS - In accordance with certain embodiments, the present invention provides a modular approach to a lubrication package. Certain components such as the filter and cooler are directly connected to a block that has connections to accept them and internal porting to establish the proper flow paths for circulation, cooling and filtration of the circulating lubricant. The block can accept one or more coolers and one or more filters. The isolation valving for redundant equipment can also be integrated into the block. Many connections that had been used in past designs for the piping network are integrated into the block. The block can also be close mounted to the reservoir while a submersible pump further saves space and piping connections. Indeed, having the ability to maintain mechanical equipment (e.g., remove and replace filters and coolers) without shutting down, allows for continuous process flow, which eliminates down-town scheduling, loss of product and/or redundant backup, all of which comes at a considerable cost. | 03-10-2011 |
