Abstract

A turbomachine housing, in particular of a radial turbomachine which transfers technical work to a process fluid or from a process fluid, includes: an opening extending along an axis, for the axial feed-through of a shaft extending along said axis; a contact surface extending along a circumferential direction with respect to the axis, for contact with a housing jacket of the turbomachine housing. A flow line provided as an inflow or outflow of the process fluid is designed as an integral part of the cover.

First claim

The invention claimed is:

1. A turbomachine housing which transfers technical work to a process fluid or from a process fluid, comprising:
a housing shell that has a substantially cylindrical shape, wherein the cylindrical shape extends along an axis,
a first cover that is provided axially on a first front face of the turbomachine housing so as to be removably fastened in a closing manner,
an inflow that allows a process fluid to flow into the turbomachine housing,
an outflow that allows the process fluid to flow out of the turbomachine housing,
wherein the first cover comprises:
an opening, extending along the axis, for the axial passage of a shaft extending along this axis,
a contact face, extending in a circumferential direction with respect to the axis, for contact with the housing shell of the turbomachine housing,

wherein a flow line, provided as the inflow or outflow for the process fluid, is configured as an integral constituent of the cover,
wherein the cover is arranged radially inside the housing shell by means of the contact face, wherein the cover is arranged with the contact face against an axial inner face of a radial inner flange of the housing shell.

2. The turbomachine housing as claimed in claim 1 ,
wherein supply lines for a shaft seal, a gas seal and/or a shaft bearing and/or oil heating and/or sensors, and/or pressure sensors, are integrated in the cover.

3. The turbomachine housing as claimed in claim 1 ,
wherein the integrated flow line has channels that divide the total flow of the process fluid into partial flows.

4. The turbomachine housing as claimed in claim 3 ,
wherein the channels are formed such that the process fluid flowing out of the channels has a particular swirl imparted to it.

5. The turbomachine housing as claimed in claim 1 ,
wherein a bearing block base for supporting a radial bearing for the shaft extending along the axis is configured as an integral constituent of the cover.

6. The turbomachine housing as claimed in claim 1 ,
wherein the cover or parts of a casting mold of the cover have been produced by means of an additive manufacturing process.

7. A method for producing the cover of the turbomachine housing as claimed in claim 1 ,
wherein the cover or parts of a casting mold of the cover are produced by means of an additive manufacturing process.

8. A turbomachine, comprising:
a rotor and a turbomachine housing,
wherein the turbomachine housing is configured as claimed in claim 1 .

9. The turbomachine housing as claimed in claim 1 ,
wherein the turbomachine housing is of a radial turbomachine.

10. The turbomachine as claimed in claim 8 ,
wherein the turbomachine comprises a radial turbomachine.
