HOW TO READ THIS MODEL

The system, explained.

Siemens Energy describes a centrifugal compression stage as a rotating impeller followed by stationary diffuser and, between stages, return-channel roles. This invented static model separates those roles across three stage groups: 24 curved impeller vanes, 24 diffuser vanes and 12 return-guide vanes are individually inspectable. A complete hollow casing and true upper discharge opening, axial suction neck, common shaft, dry-gas-seal locations, two bearing regions and a thrust-location marker provide assembly context. The studio still and reversible default viewer half-section expose the inside while the source and GLB retain the complete geometry. It is not a continuous or analyzed gas path, selected machine or operating diagram. Compare the distinct reciprocating-compressor lesson and the separate gas-compression-facility relationship scene.

Model scope and limits

Original 121-part static teaching scene with invented dimensions and materials. The full barrel has an actual inner opening and bored upper discharge; both connection necks and flanges are hollow. Stage vanes, shrouds, carrier rings, common shaft, seal locations, journal-support cues, thrust marker and bored display feet are separately inspectable. Poster-only omissions reveal vanes; the browser half-section is reversible. The layout does not prove a continuous interstage gas passage or a designed volute. No product family, gas composition, speed, pressure, compression ratio, map, efficiency, surge margin, aerodynamic profile, clearances, rotor dynamics, vibration, thrust, bearing lubrication, dry-gas-seal support, containment, rating, driver, controls, protective system, emissions or service qualification is supplied.

Which parts in the illustration are rotating-stage cues rather than stationary diffuser or return-guide cues?

GUIDED COMPONENT STUDY

Trace the system.

Read each explanation, then focus its component in the explorer. This is a learning route through the model, with no operating or maintenance sequence.

  1. Start at the open suction

    The inlet neck and flange have real centre openings. They locate a gas inlet boundary, without proving the complete interstage path or any inlet condition.

  2. Inspect the complete casing

    The GLB retains the full hollow barrel and a real upper discharge bore. The viewer begins with a reversible body-wall half-section; no pressure boundary is qualified.

  3. Find the first impeller vane

    Eight distinct invented gold strips in each of three groups mark rotating impeller roles. Their curvature is not an aerodynamic design or speed result.

  4. Compare a shroud with a vane

    The complete model keeps both annular shrouds around each stage. The studio still omits camera-facing shrouds and carriers to reveal vanes; no running clearance follows.

  5. Identify the stationary diffuser

    The silver vane is distinct from the rotating gold impeller group. It marks a diffuser role without demonstrating pressure recovery.

  6. Find an interstage return guide

    The blue return-guide family appears between the first two stage groups. The frozen parts are not a traced or loss-calculated gas passage.

  7. Compare the final stage

    A third impeller/diffuser pair is separate from the earlier groups. There is no stage-three return guide; the final collector location is only a marker.

  8. Check the open discharge

    The neck meets an actual bored opening in the casing wall. Neither this opening nor the collector annulus establishes a designed volute or discharge pressure.

  9. Locate a dry-gas-seal region

    A separate annulus marks a possible shaft-seal cartridge location. No seal faces, support system, vent or emissions result is modeled.

  10. Finish at shaft support

    The separate drive-side enclosure, journal and pad cues identify support roles. Bearing technology, lubrication, load, vibration and thrust capacity are untested.
