Definitions
- the invention relates to a single-shaft turbo compressor
- a housing for a single-shaft turbo compressor in pot construction is already known from WO2016041800-A1.
- An assembly method for a single-shaft turbo compressor in pot construction is already known from WO2015158905-A1.
- a seal for a cover of a housing of a pot-type single-screw turbo-compressor is already known from US Pat
- WO2012038398-A1 is known.
- Einwellenturbover participatr are relatively expensive to assemble, especially if - as in the present invention preferred construction as a radial compressor - the outer housing is designed for relatively high pressures without horizontal parting.
- Such pot housing must be provided by an end-side insertion opening along an axial insertion direction with the corresponding internals.
- the internals include in particular static flow installations and rotating flow installations or the rotor with the corresponding impellers, which are also called impellers.
- impellers which are also called impellers.
- the invention has set itself the task of gozubil ⁇ a machine of the type defined in such a way that a simplification of assembly and Wartungsarbei ⁇ th is recorded.
- the single-shaft turbo-compressor according to the invention is preferably a single-shaft radial turbocompressor.
- the invention is also suitable for axial compressor designs, but the achievable with radial compressors large pressure ratios are particularly useful for the pot construction of the outer housing.
- the inventively provided pot construction with the casing part and the end caps is therefore particularly useful because the casing part then does not tend to over the circumference uneven deformations and therefore no leaks caused by these deformations.
- the at least on one side axially from the inside in the shell structure of the housing at a circumferential shoulder adjacent frontal first cover is particularly advantageous because only fasteners for securing the lid must be provided in this position, which must withstand only relatively small pressure differences because in the operating state at high overpressure in the inner ⁇ ren of the outer housing of the first cover of the inner over ⁇ pressure on the contact surface is pressed in the outer housing, without that additional fastening means must be provided.
- the first lid is held in an advantageous embodiment of the invention only from the outside of the lid and optionally attached to the housing tabs in position, so that, for example, the lid retains the position when vacuum should arise in the suction region of the turbomachine.
- the increasing pressure with increasing pressure of the first cover on this inner peripheral shoulder or the contact surfaces of the shell structure of the outer housing also ensures a particularly good seal by means of there preferably axially adjacent seals.
- the static flow internals arranged in the outer housing comprise feed elements, intermediate guide elements and discharge elements.
- the Zuleite ⁇ ELEMENTS the process fluid entering through an inlet opening in the outer casing guide the rotating Strömungsleitelemen- th and the intermediate guide elements for the purpose of compression.
- the process fluid After the flow through all the impellers or recirculation stages, the process fluid reaches the flow-guiding components designated in the terminology of the invention as discharge elements, which supply the process fluid to a flow outlet from the outer housing.
- the discharge elements here are regularly formed such that the accelerated Pro is delayed ⁇ zessfluid and accordingly, a pressure build-up (according to Bernoulli) takes place.
- the Ab ⁇ guide elements comprise a diffuser, a collecting space or a collecting spiral.
- the process fluid flows from the discharge downstream downstream usually in a discharge flange from the outer housing and for further transport in a pipeline.
- connection flanges are arranged on a larger diameter, so that more space is available for their arrangement and their further connection basically. Accordingly, the first dekelkel in diameter can be made smaller, without having to take into account the dimensions of the connecting flanges.
- the entire machine can be oriented to the flow stinging ⁇ cally - thermodynamically set requirements with regard to their radial space can be optimized or reduced. This newly developed degree of freedom of the design can lead to efficiency savings, not least as a result of the fluidic optimization, as well as the material savings .
- the first shaft seal may in part as a common use of a Wellendichtungsstatorteil and a Wellendichtungsrotor- be attached to the first cover, wherein an equal ⁇ term attachment to the rotor is particularly useful, so that a common transportable unit is formed in combination with the static flow fittings ,
- a particularly advantageous embodiment of the invention provides that the first cover has a radially inwardly projecting, extending in the circumferential direction paragraph on which the first shaft seal from the outside axially abuts, so that the first shaft seal can be removed from the outside.
- the first lid rests against an inwardly projecting shoulder of the shell portion of the outer housing and thus provides for a sealing closure of the outer housing, it is advantageous if the shaft seal itself of axially au ⁇ SEN forth on a extending in the circumferential direction section of the lid sealingly so that in the context of maintenance work this shaft seal is easily removable.
- the modularity of the cover with the shaft seal and the outer housing shell ensures on the one hand for space savings and on the other hand for particularly simple maintenance. It makes sense to the waves ⁇ seals for the first cover and / or the first cover to the casing part of the outer housing each having an axially we ⁇ kenden seal are provided, so that damage during assembly is unlikely.
- the first cover is dismountable in a central part and a central part substantially concentric surrounding ring member modular, such that the ring member the radially outer periphery of the first cover for the system in the circumferential direction Having extending paragraph of the outer housing and the middle part with an outwardly ⁇ standing and circumferentially extending second paragraph on a corresponding contact surface of the ring member sealingly from the outside.
- a further advantageous development of the invention provides that supply lines and outlets of the first shaft seal extend through the first cover-namely, through the middle part and through the ring part-into a wall thickness of the shell part adjoining the first cover.
- Figures 8 and 9 are each a schematic longitudinal section of a shown in the Figure 1 de- tails VIII and IX, respectively, wherein the Thomasebe ⁇ NEN the views rotated about the axis X offset.
- FIGS. 1-8 each show a single-shaft turbo compressor STC in a schematic representation in a longitudinal section.
- the single-shaft turbo-compressor STC comprises a rotor R extending along the axis X, which has a shaft SH and an impeller IMP (referenced only by way of example) arranged on the shaft SH.
- An outer casing OC is provided CV1 and second CV2 frontal lid for sealing a shell portion BC of strictlygeophu ⁇ ses OC having a first face-side lid.
- the covers CV1, CV2 have openings OP1, OP2 through which respective ends of the rotor R extend.
- the rotor R is radially supported by bearings BG and radial bearings, wherein a thrust bearing BGA holds the rotor R in a certain axial position.
- the jacket part BC is set up with a horizontally extending axial direction along an axis X on a foot unit SUP.
- the jacket part BC has an inflow INL, wherein an existing outflow is not shown in the schematic representation visible.
- a process fluid PF flows (in the not shown operation) by the inflow INL and would be accelerated in the operation of the static flow baffles SFE and the rotating flow baffles RFE or be compacted so that IMP EXP ⁇ takes place together with an increase in pressure of the process fluid PF ,
- the single-shaft turbo compressor STC in FIG. 1 is located in a first assembly phase in which a jacket part BC of an outer housing OC which is open on both sides on the face side is not yet joined to the rest of the single-shaft turbo-compressor STC.
- the remainder of the STC Einwellenturboverêtrs comprises sta ⁇ schematic flow baffles SFE and rotating flow installation ⁇ th RFE.
- a bundle CART is preferably included according to the invention
- the second cover CV2 is spaced by means of spacers DSC of axi ⁇ al adjacent Ableitmaschinen EXE of the bundle CART axially by an axial distance gap DGP.
- spacers DSC of axi ⁇ al adjacent Ableitmaschinen EXE of the bundle CART axially by an axial distance gap DGP.
- In the Abstandshaltern DSC is here in the rougesbei ⁇ game to a plurality of axially extending screws which are screwed from the outside into the second cover CV2 and axially against the train of centrally the bundle CART axially by means of Zent ⁇ rierbauteils CE and axial bearing BGA on pressure-tightening shaft SH hold the second cover CV2 to the EXE discharge elements at a distance.
- this bundle has been further inserted into the outer housing, ⁇ OC.
- the second stage of mounting the console CON is peeled from a second roll WH2 that interacts with the shell portion BC on an inner surface in Kon ⁇ clock and there axially further into the outer housing einrü- ckend the bundle of leads.
- the centering member CE to the axial Reg ⁇ tung or clamping of the rotor R has been to the first lid CV1, which is shown in Figures 1-3 by the reference numeral CE is removed so that an opening provided by the first rotor ⁇ forming RE1 Coupling CUP can be used to attach a DR drive.
- the feed element INE keeps the rotor R during assembly substantially coaxial with the static flow fittings SFE. Is located while the second lid CV2 in the figure 4 is already in the axial end position and seals against ⁇ in this manner, the first lid has not yet arrived in the axially up ⁇ Tenden conditioning CV1 and is only with an increase of the axi ⁇ alen distance pulled to the feed element INE axially into the end position, so that an axially acting seal SAX between the casing part BC and the first lid CV1 comes to sealingly abutment.
- a attached to the first lid CV1 and on which two ⁇ th lid CV2 and sealingly attached first Wel ⁇ lendichtung Shs1 or SHS2 is axially from the outside to an inwardly projecting shoulder of the respective cover CV1, CV2, so for maintenance purposes that the respective Shaft seal SHS1, SHS2 can be pulled axially outward, if the axially adjacent components, such as bearing BG or Kupp ⁇ ment CUP have been previously removed.
- At least the first cover CVI has leads SPL and down lines EXL of the first shaft seal Shs1 on passing réellere ⁇ and are extending through the first cover CVI in a wall thickness of the adjoining the first lid CVI shell portion BC ckend provided from there in each case in at a ⁇ Flanged FG1, FG2 open, each of which is firmly connected to the Man- telteil BC.
- a static seal CSS is provided for the axial abutment.
- the first cover CV1 has a shoulder CVS extending radially inwards and extending in the circumferential direction, against which the first shaft seal SHS1 rests from axially outward, so that the first shaft seal SHS1 can be removed from the outside.
- the first shaft seal SHS1 comprises (analogous to the second shaft seal) a shaft seal rotor part SHR1 and a shaft seal stator part SH1, which are used jointly on the first cover CV1 and / or the rotor R
- FIG. 5 shows the state of the STC Einwellenturbover Whyrs in the phase of a disassembly, for example, to Wartungszwe ⁇ CKEN.
- a reduced bundle CART ⁇ is disengaged from the Jardingeophu ⁇ se OC at least partially axially.
- the reduced bundle CART ⁇ is reduced compared to the original bundle CART around the supply elements INE, the first shaft seal SHS1, the bearing BG at the first shaft end RE1.
- FIG. 5 shows that the bundle CART can also be moved as a reduced bundle CART ⁇ independently of these difference components, so that these maintenance-intensive differential components can also be processed in reverse, without necessarily moving the bundle CART or reduced bundles CART ⁇ axially ,
- Figure 6 also shows that without a movement of the complet ⁇ th bundle CART the second lid CV2 axially from the arrange- tion can be removed, so that in the field of local shaft seal, bearings and other components maintenance work with little effort are feasible.
- FIG. 7 shows that even with the first cover CV1 removed, the remaining bundle CART ⁇ can be moved axially out of the outer housing OC with an additional auxiliary tool AUT1.
