Definitions

  • the invention relates to a radial centrifugal pump with an impeller whose blades are arranged pivotable about its inner end to take a correspondingly different skew and curvature for both directions of rotation of the impeller.
  • joints 10 of the blade 4 form on the side facing the support disk in each case one in particular coaxial to the hinge axis projection in particular pin 13 which projects into a guide track 6 of the support plate 2 and is guided by them, so that for each pin 13 a guideway
  • the side wall 3 thus has radially concentric rings arranged one inside the other
  • the guideways 6 in the support plate 2 have the function to specify the limit positions for the blades 4 in both directions of rotation and to guide the blades when changing between the limit positions.
  • the position of the guideways can be chosen arbitrarily and is directed to the respective structural conditions.
  • the guideways can sometimes be used to compensate for the Axialschubs by penetrating the support plate 2.
  • the pins 13 engage as guide elements, which are connected to selected joints of the hinges.
  • the deflection of the blade in the axial direction is predetermined by the choice of the gap sizes and the tolerances of the elements used. This deflection is limited in the direction of the support disk 2 by the support disk itself.
  • the deflection in the direction of the side wall 3 can also be limited by the side wall 3.
  • the guide elements 13 penetrate the support disk 2 and at the ends of limiting elements are attached.
  • the boundary elements are designed so that they are supported on the back of the support plate 2.
  • the starting position of the blades 4 results either from the impeller assembly or from the last used direction of rotation.
  • these act on the blades both the inertial forces of the blade itself, as well as the inertia of the body of water. Due to these forces, the segments / members move counter to the direction of rotation.
  • the guide elements 13 are guided in the guideways 6 until reaching the limit positions.
  • the blades 4 move circumferentially uniformly in the joints which are connected via the rings 7. Joints that are not connected to the rings describe, when changing between the limit positions, tracks resulting from the position of guided joints.
  • An arrangement in which the side wall 3 assumes the functions of the support plate 2, while the support plate 2 takes over the functions of the side wall 3, is also conceivable and can be constructed accordingly in the given case.

Abstract

L'invention concerne une pompe centrifuge radiale avec un rotor, dont les pales sont disposées de manière à pouvoir pivoter autour de son extrémité interne, pour adopter une position oblique et une courbure différente correspondante pour les deux sens de rotation du rotor, au moins une bague coaxiale étant montée de manière à pouvoir tourner autour de son axe dans au moins une paroi latérale du rotor, et les pales étant articulées sur la bague avec au moins un emplacement situé entre les deux extrémités de pale.
