Definitions

  • the invention is based on a rotary piston machine according to claim 1.
  • a generic rotary piston engine is off DE 199 62 804 A1 known, which shows the features of the preamble of claim 1 and is considered to be the closest prior art.
  • a considerable problem in the generic field of pumps and compressors always arises when the substances to be conveyed are toxic substances which are also tough or can only be conveyed at high temperatures, which makes the cleaning of the rotating parts very demanding. make it difficult or even impossible.
  • a considerable Problem is the cleaning of the pump parts.
  • the invention is based on the object in a rotary piston engine of the generic type, in particular by overcoming the bias of the art, a -, or manufacturing process, or to develop a special construction, via which such a rotary engine can be supplied to a wide range of uses.
  • the flow-through from the medium to be pumped working spaces are closed on the base housing side facing, so that, for example acids udgl. remain in the disposable part and can be disposed of with this.
  • the housing accommodating the current coil does not form a basic housing, so that when removing the electrically flowed through the coil receiving part of the pump head with respect to the media to be conveyed no longer closed is.
  • the rotors have an interlocking Trochoidenveriereung (cycloid toothing).
  • Trochoidenveriereung cycloid toothing
  • a rotary engine is known (see genus WO 05/024236 A1 ) with the great advantage that the remaining residual spaces of the pump, ie the harmful spaces, are very small, but with respect to the invention there is a considerable bias of the art for such trochoidal rotary piston machines, in particular with regard to utilization methods, production methods or construction.
  • trochoidal toothing is a complex precision pump whose design is unusual as a disposable part for a person skilled in the art, so that a bias in the art was to be overcome here.
  • An according to claim 1 to be designed rotary piston conveyor with cup-shaped canned to facilitate the replacement of the pump head is an additional step of thought, which is unusual because the flowed through from the substrate to be pumped pump head forms by its invention interchangeability no conceptual connection to the function of the known gap motor, because for the expert in the known pumps, the split tube during operation, the flowing medium to hermetically separate the electrical part of the pump part.
  • connection between the base housing and the pump head as a Quick coupling formed, which acts on corresponding devices of the base housing and pump head.
  • the rotary piston pump comprises a base housing 1, with which the pump is anchored correspondingly fixed and in which the electrically controllable coil 2 of an electric motor is arranged.
  • a pump head 3 is shown, which can be closed by a pot-shaped can 4.
  • a ring seal 5 is disposed in a Stirnringnut 6 of the pump head 3.
  • the pump head 3 has for this purpose an annular bead 7, on which the end face 8 is present and which serves to engage a clamping ring 10, on the other hand engages an annular bead 11 of the base housing 1.
  • the clamping ring 10 is open at 12 on one side and by a screw which is tangentially inserted into an opening 13, shortened in its scope.
  • the clamping ring 10 also has conically extending webs 14, so that a shortening of the circumference of the clamping ring 10 and by its engagement with the annular beads 7 and 11 of the pump head 3 and the base housing 1 leads to their clamping together.
  • the pump head 3 receives a power rotor 15 with a permanent magnet 16 in a pot-shaped portion of the can 4, as well as a through the power rotor 15 with driven counter rotor 17 with the pivot bearing 18th
  • Fig. 2 In particular, the clamping ring 10 is shown with its open side 12th
  • the invention is not limited only to canned machines, but also detects rotary piston machines, in which the seal between the exchanged pump head and the base housing is effected by other known means. Decisive is the simple and practical interchangeability of the pump head with separation of the flow medium.
