Definitions

  • the invention relates to a rotor pump having a pump housing and a rotatably mounted therein rotor with a wing, wherein the wing is slidably mounted in the rotor and rests with its wing tips on an inner peripheral surface of the pump housing and defines a suction chamber and a pressure chamber, wherein the wing is a constant length having.
  • a rotor pump which has a pump housing in which a rotor is arranged.
  • This rotor supports a wing, which rests against the inner peripheral side of the housing.
  • the rotor is constructed in two parts so that it can take on different lengths. This ensures that the rotor always bears against the inner peripheral surface and divides the pump chamber into a pressure chamber and into a suction chamber.
  • the wing tips are provided with inserts, which consist of a hard material.
  • inserts consist of a hard material.
  • the invention has for its object to provide a rotor pump, wherein the wear is minimal.
  • the housing of the rotor pump made of aluminum, which has the advantage that the housing can absorb high forces, has a low coefficient of thermal expansion and yet easy to work.
  • the wing is preferably made of plastic and has wing tips that are harder than the inner peripheral surface of the pump housing.
  • the wing tips are made of metal, for example titanium or a titanium alloy, a sintered material or ceramic.
  • these wing tips are formed by an insert which is inserted into the wing tips.
  • a recess is provided in the wing tip, which receives the insert loose, but this fixed in at least one transverse direction to the longitudinal axis.
  • the insert is glued, injected or cast.
  • Optimal pressure forces of the wing on the inner peripheral wall are achieved by the fact that the wing is flattened in the region of its wing tip on the pressure side, wherein the flattening is at an angle to the longitudinal axis of the wing.
  • the inner peripheral surface of the pump chamber is a circular cylindrical surface.
  • the sash then makes a sinusoidal reciprocation within the slot of the rotor.
  • the distribution of forces or the load changes at the top of the wing are then continuous and not abrupt.
  • recesses or openings are provided parallel to the wing tip and the wing is slightly more elastic due to the recesses or through openings in the longitudinal direction.
  • the wing can adapt to a heat-related expanding pressure chamber, so that the tightness is still ensured both with cold and warm rotor pumps.
  • the drawing shows a generally designated 10 wings, as used for example in rotor pumps.
  • This sash separates the pump room into a pressure chamber and a suction chamber. It touches the wing with his Wings tips 12 on the inner peripheral surface of the pump housing, which is formed circular cylindrical.
  • the wing 10 has a constant length, which is tuned to the inner diameter of the rotor housing or pump chamber.
  • the contact surface on the wing tip 12 is formed by inserts 14 which are held in groove-shaped receptacles 16.
  • the inserts 14 may be loosely inserted, so that they can move only in the direction of the longitudinal axis of the wing 10. However, there is also the possibility that the inserts 14 glued into the receptacles 16, injected or poured.
  • the inserts 14 are made of a material which has a greater hardness than the inner peripheral surface of the rotor housing. Both to reduce weight and to produce constant wall thicknesses and, if necessary. To the wing 10 in the longitudinal direction slightly elastic, this has in the first embodiment, triangular openings 18 which pass through the wing 10 in the transverse direction. According to the second embodiment FIG. 2 the openings 18 have a cross-sectionally elongated opening.
  • the wing tips 12 have a flattened side 20 and a rounded side 22.
  • the flattened side 20 is on the print side which means that in the FIG. 1 shown wing 10 rotates in the clockwise direction.
