Definitions

  • the invention relates to an anti-rotation device for Elastomer stators of eccentric screw pumps, whereby the metallic, the elastomer lining enclosing jacket of the stator with at least one is provided essentially radially projecting pin, on fixed parts, especially parallel to the stator arranged anchor bolts of the eccentric screw pump for Stop can come.
  • Stator jacket with a threaded hole Element preferably a threaded nut, into that with a corresponding external thread provided pin is screwed. So that's the Pin releasable or at any time attachable or even replaceable. According to that can also the stator initially with a tight fitting Protective film are provided, which is also the threaded hole can cover up. To the under these conditions To be able to attach cones, the film is in the area Simply pierce the protective film so that the To be able to produce screw fastening.
  • the pin is also expediently made elastic deformable cover, preferably in the form of a tight provided hose section to the To improve the stop behavior of the pin. It is it is very beneficial if the spigot has a length away, but at least over part of its length the screw thread is provided in such a way that the The hose section to a certain extent on the spigot can be screwed on so that the hose section not only due to its elastic inherent tension, but also also at least slightly positive hold.
  • the proposal according to the invention is suitable in advantageous for such stators, whose over their length provided with uniform wall thickness Coats of the spiral of the mold cavity (cavity inside the stator to accommodate the rotor) are shaped accordingly.
  • Coats of the spiral of the mold cavity cavity inside the stator to accommodate the rotor
  • it will Element with internal thread in a through the Coil-induced deepening of the stator sheath arranged so that the element the outer contour of the Stator not towered over or only slightly.
  • the pin can - as already mentioned - the Pierce the protective film in the area of the threaded hole become.
  • the steel jacket 1 of the stator encloses an adhered lining 2 made of rubber od. Like .. Your inner surface limits one Pump cavity 3, which is coiled several times and one also coiled rotor, not shown records.
  • the longitudinal central axis is designated 4.
  • stator When installed, the stator is between two End rings of the pump frame clamped by distributed over the circumference of the stator, parallel to the stator extending anchors are connected, one of which at 5 is indicated.
  • an anti-rotation device is provided attached in the form of an outside on the jacket 1, about radially projecting pin 7 made of steel.
  • the pin 7 is along its length with a Provide thread and by screwing into an outside nut 8 welded to jacket 1 releasable or optionally attached to the stator afterwards.
  • the jacket 1 is practical over its length same wall thickness and the winding of the Pump cavity 3 coiled accordingly. For this Basically, it is possible to use the mother 8 in one To fix spiral-related recess 9.
  • the pin 7 with the thread mentioned has the advantage that it can be screwed on. In addition, with help the thread of the hose 11 attached. A relaxation the pin 7 is excluded because its lower end against the outer surface of the jacket 1 by tightening can be countered to a certain extent.
