摘要： A support structure with a mounting area to receive a fluid moving unit (e.g., a compressor, a blower, etc.) of a fluid-handling system. The support structure is configured to support the fluid moving unit in position at a plant or facility. In one embodiment, the support structure includes an enclosure with an interior cavity having an inlet and an outlet, which couples with the fluid-moving unit. Inside of the interior cavity, the enclosure can comprise a noise reduction structure to dissipate energy in a flow of working fluid that flows between the inlet and the outlet in response to operation of the fluid-moving unit. The noise reduction structure can include a pair of tubular members that extend along a longitudinal axis within the mounting area. Each of the tubular structures have a hollow interior and openings that expose the hollow interior to the interior cavity.

摘要： A lubricating assembly that is configured as part of a lubricating system that flings, or slings, fluid lubricants about the interior of rotating machinery. In one embodiment, the lubricating assembly includes a bearing clamp member with a clamp body having an outer peripheral edge that has an annular profile that partially circumscribes a longitudinal axis. The annular profile can have first annular section with a first clamp surface and a second clamp surface disposed in opposing relation about a centerline and spaced apart from one another to form a first annular gap. At the bottom of the clamp body, the bearing clamp member is configured with a peripheral wall that bounds a reservoir region. This configuration allows the fluid lubricants to gravity feed through the first annular gap into the reservoir region to retain a volume of the captured lubricant to lubricate moving parts of the lubricating system.

摘要： The disclosure describes a flow conditioning device for dampening pulses and improving performance of a compressor. In one approach, a diffuser device includes a housing member having a first end and a second end, the housing member coupled to an outlet of a compressor, and a diffuser member disposed within the housing member. The diffuser member is in fluid communication with a working fluid delivered from the compressor, and includes a core member extending along a longitudinal axis of the diffuser member, and a plurality of flutes extending radially from the core member. In some approaches, the plurality of flutes and an inner surface of the housing define a plurality of fluid channels for delivering the working fluid from the first end to the second end of the housing member. In some approaches, the diffuser member is rotatably coupled to the housing member.

摘要： A compressor or blower includes an impeller disposed on a high-speed shaft, a motor shaft that extends from an end shield of a motor, a gearbox, and a lubrication system. The gearbox is disposed between the motor and the impeller and includes a pinion disposed on the high-speed shaft and a bull gear disposed directly on the motor shaft in engagement with the pinion. The lubrication system includes a single pump module that is configured to wet bearings on the high-speed shaft prior to starting the motor and to mechanically pump oil to the bearings during operation of the motor.

摘要： A lubricant assembly that is configured as part of a lubricating system that flings, or slings, fluid lubricants about the interior of compressors. In one embodiment, the lubricant assembly includes a lubricant guide member with a body member that has a pair of peripheral side members with angled surfaces. The construction is amenable to more consistent fabrication constraints (e.g., tolerances), as well as to offer features that can improve operation of the lubricating system, e.g., as operative in the compressors. In use, the lubricant guide member is disposed transverse to a longitudinal axis of a shaft that is configured to rotate a slinger member to fling the lubricant. This configuration captures lubricant that falls downwardly from other parts of the compressors. The angled surfaces of the side members direct this captured lubricant toward the shaft, and other rotating components, of the lubricating system.

摘要： A system for configuring a flowpath in a compressor. The flowpath is configured to direct working fluid from an impeller inside of a volute casing member to a nozzle member on the compressor. In one embodiment, the system can include a first member and a second member, each being removebly replaceable from the volute casing member of the compressor. In use, changes in one or both of the first member and the second member define geometry for the flowpath to match the frame size of the impeller with the flow parameters of flow that exits the compressor.

摘要： An impeller for a compressor that incorporates geometry to enhance mechanical and fluid dynamic properties of the blades. In one embodiment, the impeller comprises an annular body with a longitudinal axis. The annular body has a first end with a first diameter and a second end with a second diameter that is larger than the first diameter. The impeller also has a blade disposed on the annular body that extends axially along the longitudinal axis. The blade has a root proximate the annular body and a top disposed radially outwardly of the root. The impeller also has a joint region extending along the root of the blade, the joint region having a profile that varies along the longitudinal axis. The profile can define an arc that has a radius that decreases along the longitudinal axis in the direction from the first end to the second end of the impeller.
