Definitions

  • PATENTEDJULSOIBH SHEEY 3 0F 4 CENTRIFUGAL GAS COMPRESSOR UNIT This invention pertains to gas compressors, and in particular to a high speed multi-housing, multi-stage centrifugal gas compressor unit, for high compression ratios, having as its primary application natural gas service such as gathering, pipeline feed, gas injection and gas lift.
  • centrifugal compressors used for natural gas service employ two, or three multi-stage centrifugal compressor units arrangedfin line, driven through a step-up gear, and coupled through high-speed couplings.
  • Such arrangements are very susceptible to vibration, when the alignment becomes distorted.
  • the individual compressor units are vibration-sensitive because of the long shaft overhangs, particularly on the thrust bearing end.
  • Compressor unit maintenance and servicing are time consuming, because the housings or casings of some of the machines, and usually portions of their associated piping, must be completely removed from a baseplate to gain access. So also, the in line arrangement requires a very elongatebaseplate, which is space consuming, and therefore costly, particularly wherein the machinery is mounted on an off-shore platform.
  • a centrifugal gas compressor unit comprising a plurality of separate, elongate, gas compressor housings; a plurality of successive gas compressing stages within each of said housings; means for admitting gas to a first of said housings; means for discharging compressed gas from a last of said housings; means for communicating gas between each of said housings for successive gas compression; said stages each comprising a bladed gas compressor impeller and a vaned diffusor; a shaft confined within each of said, housings, rotatably supporting said impellers; bearing means interposed between each of said shafts and housings for supporting said shafts for rotation; a gear housing, having parallel spaced apart walls, integral with said compressor housings; said compressor housings extending in parallel axes from, and perpendicular to, one of said walls of said gear housing; each of said shafts extending through both of said walls, and having a hollow gear shaft concentrically engaged therewith; each of said gear shafts carries gear means intermediate said walls; an
  • a feature of this invention comprises a multi-housing compressor having a plurality of gas compressing stages in each of parallel housings, the housings being integral with and extending perpendicularly from a gear housing. Rotor assemblies and associated diffusors are slidably replaceable from the respective housings, obviating any requirement to dismantle the gear housings. While the housings each receive gas, sequentially, for further compression, impellers andshafts in a plurality of the compressor housings are of identical weight, with the impellers thereof identical axial length albeit of differing diameters.
  • FIG. 1 is a front, elevational view of an embodiment of the novel centrifugal gas compressor, according to the invention, with the cover plate removed for purposes of clarity;
  • FIG. 2 is a rear elevational view of the embodiment of FIG. 1;
  • FIG. 3 is a fragmentary and half axial illustration of the driving gear within the gear housing
  • FIG. 4 is a fragmentary view of the idler gear within the gear housing
  • FIGS. 5 and 5A are broken, half axial views partly in cross-section, of the second compressor housing. Views 5 and 5A are broken on section lines AA and are to be understood to be substantially symmetrical about the axial centerline thereof;
  • FIG. 6 is an axial illustration of the impeller shaft of the third compressor housing, with but halves of the im pellers thereof shown in cross-sectiomand
  • FIG. 7 is a simple diagrammatic illustration representative of the novel arrangement set forth herein for coupling the impellers to the impeller shafts.
  • the compressor 10 comprises a baseplate 12 which supports a gear housing 14.
  • a plurality of three barrels or compressor housings 16, 18 and 20, are integral with the gear housing, and, extend therefrom, perpendicularly, in parallel axes.
  • the gear housing 14 is defined by an inner wall 22 and an outer wall or cover plate 24.
  • Driving gear 26 (FIG. 1) is in mesh with gear 30 of the first compressor housing 16, and with the idler gear 28.
  • idler gear 28 is in mesh with gears 32 and 32' of the second and third compressor housings 18 and 20, respectively.
  • Driving gear 26 is mounted on a shaft 34 which has a coupling end 36 projecting from the outer wall or cover plate 24, whereat a prime movercan be coupled to impart driving torque to the gear train.
  • the gear housing 14 confines therewithin a reservoir 38, shown in FIGS. 1 and 5.
  • Reservoir 38 has a plurality of outlet ports 40 which receive conduits 42.
  • the conduits 42 are flexible and are conformed to open onto those locations within the gear housing 14 whereat the gears of the gear train mesh.
  • a pair of limbs 44 disposed between the baseplate 12 and gear housing 14 have conduits or passageways (not shown) formed therein, and lubricant discharged by conduits 42 is scavaged therethrough for collection in a sump (not shown) mounted therebelow.
  • the several housings have, inlet and outlet flanged ducts for admitting gas, sequentially to each of the housings in turn.
  • inlet flanged duct 46 admits gas to the first housing 16, this housing having an outlet flanged duct 48.
  • the latter duct by means of piping (not shown) communicates with the inlet 3 flanged duct 46 of the second compressor housing 18, and gas discharged therefrom is passed through its outlet flanged duct' 48' to compressor housing 20.
  • the latter also has both an inlet flanged duct 46 and an outlet flanged duct 48" for discharging the final, totally compressed gas product to a using end item (or to storage).
  • FIGS. 5 and 5A only one compressor housing, specifically the second compressor housing 18, is shown.
  • impeller dummies 64 are carried on the other end of the impeller shaft 50.
  • the dummies 64 are of the same axial length as each of the impellers 52 so that when it is desired to increase or decrease the compressor housing capability it remains only to substitute impellers for one or more of the dummies 64, or vice versa.
  • the rotor assembly comprising the impeller shaft 50, the impellers 52 and the dummies 64, together with the diffusors 54 and housing 56, are slidably removable, as a unit, from the end of housing 18 which is most remote from the gear housing 14, upon removal of retainer 66 whereupon bench dismantling of the unit can follow.
  • Retainer 66 is engaged .with an end seal 68 for securing the removable unit in the housing 18.
  • Retainer 66 in turn, is held within the housing by a split ring 70 and an retaining ring 72. Both rings have surfaces which define a tapered wedge interface.
  • Mounting and tensioning hardware (not shown) secures ring 72 to the retainer 66.
  • a lubricantpassageway 74 is formed within the housing wall or cover plate 24 for admitting lubricant into the reservoir 38, and also for conducting lubricant to shaft bearing 76.
  • reservoir 38 in addition to serving as a lubricant manifold, also serves to suppress the emission of gear-noise from the gear housing 14. As FIGS. 1 and 5 evidence, the reservoir extends fully across the housing 14, and substantially envelops the gear train. In defining a hollow, walled structure, which is substantially closed, it presents a sound buffer intermediate the gear train and the external periphery of the housing 14.
  • the impeller 52 to the impeller shaft 50 without any requirement for keying, bolting, or heating.
  • the nominal inside diameter 82 of the impellers corresponds substantially with the nominal outside diameter 82' of the impeller shaft.
  • the impeller mounting bores as well as the outside diameter of the shaft are formed as something other than true circles. That is, as shown in FIG. 7, a true circular surface it formed about the shaft, and within the impellers, would be represented by the dashed lines and the solid lines contiguous therewith.
  • the impeller bores and the shaft outside diameter or periphery are formed with eccentric surfaces 84 which, therebetween, define three lobes 86.
  • the impellers With the impeller bores and the shaft surface aligned, lobefor-lobe, the impellers are freely, slidably mountable onto the shaft. Then, by forcefully torquing the impellers on the shaft, the priorly aligned lobes separate, rotationally, and effect a binding, circumferentialwedging relationship with" adjacent surfaces 84. It is a teaching of this invention to torque these lobes 86 into such a bound engagement with the adjacent eccentric surfaces 84, as will be greater than any contrary torquing force experienced by the impellers while compressing gas. When necessary to remove an impeller it remains only to reverse the torque lock-up rotation to again slidably align the lobes of both of the impellers and the shaft, whereupon the impellers can be slid off the shaft.
  • the gear train as is evidenced in FIGS. 3, 4, and 5, comprises helical gears which are so oriented as to counter the thrust normally developed by the rotor assembly. Therefore, the thrust bearing 88 (FIG. 5) need not be so large as ordinarily would be necessary. This offers no small economies in machine-space requirements and costs.
  • Housings l8 and 20 contain shafts 50 and 50, respectively (FIGS. 5, 5A, and 6) which are identical in length, weight and configuration. So also, the impellers 52 are identical in weight and axial length AL with impellers 52. This is true, notwithstanding the fact that impellers 52 and 52' have different diameters D and D. This is arranged by having impellers 52 with weighting metal downstream of the blade surface. The common weight and length of these rotor assemblies, and the standard axial length of the impellers, greatly simplifies the fabrication, balancing, and alignment of the compressor unit 10.
