摘要： 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.

摘要： 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.

摘要： 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.
