Abstract
A housing 1 for a centrifugal compressor 40 with a centrifugal impeller 42 has a front cover 2. The front cover 2 defines a central axis 6 and has an axially oriented inlet 8, a diffuser 10 in fluid connection with the inlet 8, a collector 12 in fluid connection with the diffuser 10, and a rear cover opening which is opposite of the inlet 8 and designed to sealingly receive a rear cover 4. The diffuser has a first diffuser wall 30 and the collector has a collector wall 15. The front cover 2 is made of a three-dimensionally shaped base 22 and a separate disk-shaped diffuser wall part 24 which is attached to the three-dimensionally shaped base 22 for forming the diffuser 10 and the collector 12.
Claims19
A housing for a centrifugal compressor, comprising:
- a front cover, and
- a separate diffuser wall part which is disk-shaped and comprises a diffuser side and a collector side opposite of the diffuser side,
- wherein the front cover defines a central axis and comprises an axially oriented inlet, a first diffuser wall of a diffuser, wherein the diffuser is in fluid connection with the inlet, a collector wall of a collector, which wherein the collector is in fluid connection with the diffuser, an outlet in fluid connection with the collector, and a rear cover opening which is opposite of the inlet and designed to sealingly receive a rear cover, wherein the rear cover comprises a second diffuser wall of the diffuser, and wherein the second diffuser wall faces the first diffuser wall after assembly of the rear cover in the rear cover opening, and
- wherein the front cover comprises a three-dimensionally shaped base that has a groove and the separate diffuser wall part, and wherein the separate diffuser wall part has an inner opening with a circumference that corresponds to the groove of the three-dimensionally shaped base and wherein the inner opening of the separate diffuser wall part is received in the groove and is attached by shrink-fit to the three-dimensionally shaped base, and the first diffuser wall comprises the diffuser side of the separate diffuser wall part and the collector wall comprises the collector side of the separate diffuser wall part.
A method for producing a housing for a centrifugal compressor, comprising the following steps:
- providing a three-dimensionally shaped base for a front cover,
- providing a separate diffuser wall part, which is disk-shaped and comprises a diffuser side and a collector side opposite of the diffuser side, and
- shrink-fitting the separate diffuser wall part to the three-dimensionally shaped base for forming the front cover, wherein the front cover defines a central axis and comprises an axially oriented inlet, a first diffuser wall of a diffuser, wherein the diffuser is in fluid connection with the inlet, a collector wall of a collector, wherein the collector is in fluid connection with the diffuser, an outlet in fluid connection with the collector, and a rear cover opening which is opposite of the inlet and designed to sealingly receive a rear cover, wherein the rear cover comprises a second diffuser wall of the diffuser, wherein the second diffuser wall faces the first diffuser wall after assembly of the rear cover in the rear cover opening, and wherein the attaching of the separate diffuser wall part to the three-dimensionally shaped base completes the first diffuser wall with the diffuser side of the diffuser wall part and completes the collector wall with the collector side of the separate diffuser wall part.
