Definitions

  • the invention relates to a pump with a Axial direction wavy and cylindrical on its circumference molded pump element, which is attached to a a pump housing mounted rotor shaft in one Pump channel of the pump housing rotates.
  • a pump of this type is from Germany Publication DE 34 18 708 A1 known.
  • This pump has a rotor located in a pump channel which the pump element protrudes collar-shaped is.
  • the pump element is in its axial Longitudinally wavy while its Circumferential surfaces are circular cylindrical.
  • the rotor is connected to a drive Rotor shaft fastened and rotated in one in the Pump housing trained pump channel with a Pump inlet and a pump outlet is connected.
  • For Seals between the inlet and outlet of the pump are in the pump channel axially displaceable sealing elements provided against the working surface of the pump element be pressed and the wave motion of the rotating Pump elements follow.
  • the well-known pump has with regard to their Conveying capacity especially when conveying thick matter as proven reliable.
  • their use is problematic when the pump is used in the aseptic area should.
  • the known pump has it has been found that there is contamination in the Pump channel conveyed goods through from outside into the pump entering particles can come. Beyond that it comes due to the construction of conventional seals Residual deposits of the material to be conveyed, which is also a Can cause contamination of the conveyed goods. This applies especially when the rotor and shaft bearings due to the design-related required Running play to excessive stress on the seal and ultimately leads to their destruction.
  • the object of the invention is a pump improve the type mentioned in that a Contamination of the pumped to the pump in the pump channel Good by entering the pump housing from the outside Particle is excluded and a deposit of Conveyed material is avoided, as well as damage to the pump is excluded due to overheating.
  • the slide ring elements are concentric stressed and flushed Pump interior arranged. This arrangement allows the inside of the pump to be Easy to clean slide ring elements. On this is the case when using the pump Aseptic area a termination of the pumped goods with impurities excluded at all times.
  • the wear of the sealing element can be thereby reduce that in the flat face of the pump element a recess is formed in which a slide ring at which the in the annular groove of the Sealing element is seated in the housing opening. In this way it is possible to use the material of the seal and the material of the slide ring in an optimal way to coordinate with each other so that good sliding behavior can be achieved with little wear on the seal can.
  • cooling fins are vertical extend, because in this case, which is characterized by the Convection of the heated ambient air natural air flow can be used.
  • This Cooling can also be used to cool the Pump housing can be used when the cooling fins are on the end face of the pump housing assigned Extend the bearing flange.
  • the Cooling effect of the cooling fins are supported, that the cooling fins from that through the rotor shaft flowing coolant are flowing.
  • the pump has a pump housing 1, which on a Bearing flange 2 is attached.
  • a housing opening 3rd molded through which a one-sided through bearing 4 in the bearing flange 2 mounted rotor shaft 5 in the Pump housing 1 is guided.
  • annular groove 11 formed, which does not have a shown channel connected to a superheated steam inlet 12 is.
  • annular sealing element 13 At the front end of the annular groove 11 is a annular sealing element 13, which has a annular pressure piece 14 by the force of a Coil spring 15 is spring-loaded, which between the Thrust piece 14 and the rear shoulder of the annular groove 11 is clamped.
  • a second annular groove-shaped recess 16 is formed in the rear facing the housing opening 3 flat end wall 6b of the hub 6a of the pump element 6 .
  • a sealing ring 17 In this recess 16 is a sealing ring 17, the has a rectangular cross section.
  • the thigh of the sealing ring 17 seal against a slide ring 18 the outer wall 16a and the end wall 16b of the recess 16 from.
  • the end face of the slide ring 18 lies against it the sealing element 13.
  • the sealing element 13 is also under pressure Superheated steam pressed against the slide ring 18. This slides with the pump element 6 rotating on the sealing element 13, whereby at the same time the Sealing effect of the ring seal 17 is supported. On this is a permanent seal of the pump channel 9 compared to the superheated steam in the annular groove 11 sufficient contact pressure is ensured at the same time.
  • the Rotor shaft 5 For cooling the rotor shaft 5, which by the in Ring groove 11 pending hot steam is heated, the Rotor shaft 5 has an axial bore 19 with radial Channels 19a, b of the rotor shaft 5 into one Cooling pipe system is connected.
  • the radial Channels 19a, b open into annular grooves 20,21 which in the Outside of the rotor shaft 5 are embedded.
  • the first Ring groove 20 forms with the inner wall of the opening of the Bearing flange 2 a chamber, over the compressed air, which enters the chamber via a compressed air connection 22, fed into the cooling line system of the rotor shaft 5 becomes.
