Embodiment Construction

[0034] figure 1In a longitudinal sectional view, a part of a compressor 1 is shown, which has a collecting chamber 2 according to the invention, which extends in the circumferential direction around the machine axis 3 . The compressor 1 has a rotor 4 , at the end shown of which is arranged an impeller 5 (compression stage of the centrifugal compressor), which forms the free end of the shaft of the rotor 4 . The impeller 5 is axially flowed by the fluid 7 via the inflow means 6 and conveys the compressed fluid radially outwards into the peripheral chamber 8 . After a further 90° deflection 9, the fluid 7 flows from the peripheral chamber 8 into the collecting chamber 2, collects there, and enters the subsequent diffuser 10 (deflected in the circumferential direction) in a manner not shown separately. location shown).

[0035] The collecting chamber 2 is formed by an outer housing part 21 and a contour insert 22 . The slot in the housing part 21 into which the profile insert ...

Abstract

The invention relates to a collecting chamber (2) of a flow machine (condenser 1), which expands in the direction of circumference, comprising at least one outer shell part (21) and a contour insert (22), wherein the contour insert (22) is provided with a groove (26) which extends in the circumferential direction and is preferably configured as a helical spiral. According to the invention, the contour insert (22) is cut from a whole unit and is delimited at one end in the circumferential direction by a bent edge (33) so that the flow losses are minimized during the passage from the collecting chamber into a subsequent diffuser (10).

Description

technical field [0001] The invention relates to a fluid machine collecting chamber, which widens in the circumferential direction and extends over at least a part of the periphery of the machine axis, the collecting chamber being composed of at least one outer housing part and a profile insert Formed, the profile insert comprises a groove with a groove bottom, the groove is milled from a solid body and extends in the circumferential direction and is laterally limited on at least one side, the collecting chamber has a first circumferentially extending A flow opening (which is basically configured for axial flow) and at least one second flow opening (which is basically configured for radial flow), wherein the groove has a first end in the circumferential direction and The second end in the circumferential direction, wherein the second end of the collecting chamber in the circumferential direction opens into the second flow opening. Background technique [0002] In fluid machi...
