The invention relates to a method for reducing undesirable axial deformation of an end wall (2, 3, 7) of the rotor of a centrifugal separator. This axial deformation is essentially the result of the axial forces that are engendered by liquid in the rotor during centrifugation. The axial deformation of the end wall is reduced by stiffening the end wall in its radial direction by means of a stiffening element (5) which is fitted concentrically around the rotor axle and connected to parts of the end wall so that the stiffening element is able to take-up forces which act radially on the end wall during rotation of the rotor in order to counteract radial deformation of the end wall resulting from axial deformation of said end wall. The invention also relates to an arrangement for use when applying the method. |
