Horizontally split flow machine housing
View Patent ↗A horizontally split flow machine housing, particularly for a radial compressor, has a top housing part and a bottom housing part and a top stator part which is received in the top housing part and is prevented from falling out in that the top stator part is supported from the top by stator stops on housing stops. At least one housing stop is fastened to the top housing part in such a way that it can be adjusted toward a stator stop during assembly and is supported at the top housing part below a point of contact between the stator stop and housing stop.
1. A flow machine housing configured as a horizontally split flow machine housing, comprising:
a top housing part, the top housing part comprising at least two housing stops;
a bottom housing part configured to mate with the top housing part; and
a top stator part configured to be received in the top housing part, the top stator part comprising at least two stator stops configured to mate with respective housing stops to fix the top stator part to the top housing part
wherein at least one of the two housing stops is adjustably fastened to the top housing part such that it is adjustable toward a respective stator stop and is supported at the top housing part below a point of contact between the stator stop and housing stop wherein the at least one adjustable housing stop extends diagonally from a partition line between the top housing part and the bottom housing part and adjustable in a direction towards the respective stator stop.
2. The flow machine housing according to claim 1 , wherein the adjustable housing stop comprises a screw.
3. The flow machine housing according to claim 2 , wherein the adjustable housing stop is a threaded pin.
4. The flow machine housing according to claim 1 , wherein at least one stator stop is a cutout.
5. The flow machine housing according to claim 4 , wherein at least one stator stop is a milled flat.
6. The flow machine housing according to claim 1 , wherein the top stator part is supported on the housing stops such that the housing stops are subjected to compressive loading.
7. The flow machine housing according to claim 6 , wherein a component of the force exerted by the top stator part on a housing stop in its adjusting direction is at least equal to a component perpendicular to the adjusting direction.
8. The flow machine housing according to claim 7 , wherein a component of the force exerted by the top stator part on a housing stop in its adjusting direction is at least √3-times the component perpendicular to the adjusting direction.
9. The flow machine housing according to claim 1 , wherein the at least one stator stop is loosely supported on the respective housing stop.
10. The flow machine housing according to claim 1 , wherein the at least two stator stops are formed on opposite sides of the top stator part.
11. The flow machine housing according to claim 1 , wherein the top stator part is substantially shaped as a partial ring.
12. The flow machine housing according to claim 1 , wherein the top stator part defines a flow channel of the flow machine.
13. The flow machine housing according to claim 1 , wherein the top stator part is received in a groove of the top housing part and is secured in axial direction.
14. The flow machine housing according to claim 13 , wherein the at least one housing stop projects at least partially into the groove in the final assembly position.
15. The flow machine housing according to claim 1 , wherein the top housing part and the top stator part have joint faces that are flush with one another in the final assembly position.
16. The flow machine housing according to claim 1 , wherein the adjustable housing stops one of:
terminate flush with a joint face of the top housing part in a final assembly position and
terminate recessed from the joint face of the top housing in the final assembly position.
17. The flow machine housing according to claim 1 , wherein the flow machine is a radial compressor.
18. The flow machine housing according to claim 1 , wherein the top stator part is a half-ring.
19. A method for assembling a flow machine housing comprising:
receiving a top stator part having a stator stop in a top housing part, the top housing part having at least one adjustable housing stop;
adjusting the at least one housing stop toward the stator stop; and
connecting the top housing part and a bottom housing part to one another,
wherein the at least one adjustable housing stop extends diagonally from a partition line between the top housing part and the bottom housing part and is adjustable in a direction towards the stator stop.
