Description
8005754-0 II.) att ske. I närheten av löphjulets nav sörjer de åter- stående styrflänsarna för en likríktning av genomflödet och därmed för en stabilisering av Q-H-linjen.
Uppfínningen kommer i det följande att närmare beskrivas med hänvisning till ett i bifogade ritning visat utförings- exempel.
Det transporterade mediet strömmar genom en ínloppskrök 1 till löphjulet 2 i en centrifugalpump. I omlänkningsområdet i inloppskröken finns anordnat styrflänsar 3 vilka i det här valda exemplet samverkar med en mittför löphjulsnavet U belägen inloppskägla 5. Styrflänsarna 3 är i området för ytterdiametern 7 för kröken bortskurna framför löp- hjulet och endast en styrflänsrest 6 återstår i löphjuls- omrâdet i närheten av navet.
