Definitions
- the invention relates to a housing having a longitudinal axis of a turbomachine extending along a rotor, in particular turbocompressor housing, comprising at least one jacket part extending along the longitudinal axis and at least one frontal lid, which lid is surrounded by the jacket part at least with part of its axial extent.
- Such housings are used independently in connection with virtually any turbomachine, whether it is an axial flow or a radial flow turbomachine. These designs are also conceivable for
- Turbomachinery with a horizontally split housing or turbomachinery in pot construction or with a vertical parting line. Both with relaxing turbomachinery and with compressing turbomachinery are the pressures and
- Housing thus allow, for example, part joints or other closable opening options, such as frontal lid. Another weak point of the housing and the overall construction is often due to
- the shaft seals are often areas that are as small as possible with respect to the shaft
- the invention has therefore taken on the task, the housing of the type mentioned in such a way that the radial play demand is reduced, without compromising on the availability or safety of the operation of
- a housing of the type defined which additionally has the features of the characterizing part of claim 1.
- the cover has at least one radially projecting shoulder which preferably extends in the circumferential direction and which extends from the inside on a shoulder of the housing, which also extends preferably in the circumferential direction, radially inwardly projecting
- Forming components has the great advantage that the tolerance chain with respect to these radial play relevant components is much shorter, so that one already
- Arrangement is particularly sensitive to radial misalignments of the lid, so that here an application of the invention is particularly useful.
- the invention is that the lid relative to the housing a
- the invention enables a relative movement of areas of the lid relative to the
- the lid is centered in the area to the shell portion of the housing, which defines the intersection of the longitudinal axis with the lid.
- Support is also very useful in the context of assembly, because no provisional supports must be provided for such a lid.
- the lid has formations which support the weight of the lid in recesses on the parting line of the housing. These recesses are suitably designed so that the formations on the lid restrict bidirectional vertical movement.
- the mobility is not limited by the centering itself.
- the centering which is arranged along a vertical line through the longitudinal axis, should be bidirectional
- the two guides have only one contact surface on the lid and the centering has two contact surfaces to the lid.
- a preferred field of application of the invention are covers with an outside diameter of 1000 mm or more.
- the guide elements are designed such that during operation, the radial clearance substantially
- the invention is particularly useful with large lids (diameter over 1000mm), especially when the lid is a b
- Fastening elements for fixing it lid are provided on the b casing part and the lid, wherein a
- Bearing surface is directed opposite, so that a
- Horizontal are arranged through the longitudinal axis, it may lb preferably be guide elements, at least
- two horizontal supports are provided on the casing part, on which the lid is supported against the action of gravity and in addition to the
- Shell part expediently provided a guide, the one
- Guide elements which are designed as horizontal supports define together with the longitudinal axis of the
- the third guide which is a horizontal movement perpendicular to the longitudinal axis of the shell part
- the lid is preferably a carrier of at least one shaft seal, which seals a circumferential gap between the rotor and the lid at the opening.
- the cover may be suitable carrier of a radial bearing for supporting the rotor.
- the shaft seal comprises a dry gas seal.
- the shaft seal a in the case that the shaft seal a
- Dry gas seal comprises, the lid is advantageously equipped with a heater, which in the case of very cold process gases, the dry gas seal to a suitable
- a preferred application of the invention provides that the housing has a parting line parallel to the longitudinal axis,
- the invention is based on a special
- Turbo compressor which shows essential parts of a housing according to the invention
- FIG. 2 shows a view of the turbocompressor in FIG.
- FIG. 1 by means of II,
- FIG. 3 shows a detail view from FIG. 1 in the assembly
- Figure 4 is a detail view of the figure 1 in operation.
- FIG. 1 shows a turbomachine TM, namely a
- Turbo compressor TCO with a housing CAS according to the invention, or a turbocompressor housing The housing CAS extends along a longitudinal axis AX and has a horizontal parting line TF, which by means of partial joint screws TFS is held together.
- the housing CAS can be subdivided into a shell part SH and a cover COV.
- the shell part SH is provided with the horizontal parting line TF.
- the cover COV is undivided, has a substantially planar extension perpendicular to the longitudinal axis AX with a substantially round outer contour.
- the lid COV carries a shaft seal SSL and a radial bearing BE.
- the shaft seal SSL comprises in axial order from inside the machine
- the turbocompressor TCO is for
- Boil-off gas compression is provided, which is associated with temperatures in the range of -160 ° C of the process gas.
- COV is in the lid
- Heating HEA integrated which adjoins the dry gas seal DGS.
- the heater HEA is using oil OL as
- Heat exchanger medium operated.
- the cover COV comprises a base element BE and a ring element RE, which encloses the cover COV from the outside on the housing CAS
- Ring element RE has a circumferentially
- the two guides GE each form a horizontal support SUPH, which support the cover COV in the region of the horizontal parting line TF against a weight G.
- the centering CCE is a horizontal centering ZEH and blocks a movement of the cover COV perpendicular to the longitudinal axis AX of the shell part SH in
- the centering CCE blocks a horizontal movement perpendicular to the steering axis AX on both sides; it has two
- the center guide CCE which can also be referred to as horizontally acting centering, is with the contact surfaces SC and the
- the cover COV has over the shell part SH on a radial clearance RCL.
- the cover COV has a circumferentially
- first contact surface SFCOV which cooperates sealingly with a second contact surface SFCAS on the shell part SH, wherein a surface normal of the second
