Definitions

  • the invention relates to an eccentric screw pump with at least one stator made of an elastic material and a rotatable or rotatably mounted in the stator rotor, wherein the stator is at least partially surrounded by a stator jacket, which is also referred to as a stator housing, wherein the stator jacket as a longitudinally divided shell at least two shroud segments and forms a Statorspannvorraum with which the stator is clamped in the radial direction against the rotor.
  • the rotor is regularly connected to the drive or drive shaft via at least one coupling rod, which is also referred to as a cardan shaft.
  • the pump has a suction housing and a connecting piece, wherein the stator is connected at one end to a flange of the suction housing and the other end to a connecting flange of the connecting piece.
  • Elastic material means in particular an elastomer, for example a (synthetic) rubber or a rubber mixture.
  • composites made of an elastomer or another material, eg metal are also included.
  • the (elastomeric) stator is formed as a longitudinally divided stator of at least two partial stator shells.
  • the stator preferably consists of two stator half shells.
  • the stator shell consists of at least two shell segments, for example three shell segments or at least four shell segments, which form a stator tensioning device.
  • stator or the Statorteilschalen lie with end sealing surfaces against corresponding sealing surfaces on the respective housing part (suction housing or connection piece) or on corresponding adapter pieces.
  • adjusting elements are provided, e.g. Adjusting screws, which are e.g. work in the radial direction of the shroud segments or their end-side clamping flanges, so that the shroud segments are clamped with these screws in the radial direction against the stator.
  • An eccentric screw pump of the type described in the introduction is e.g. known from WO 2009/024279 A1.
  • the shell segments of the stator shell have end attachment flanges, which are connected for the purpose of clamping the stator with clamping means to the connecting flange of the suction housing or connecting piece or to separate adapters.
  • These clamping means or adjusting means are designed as adjusting screws, which are oriented substantially in the radial direction.
  • the known eccentric screw pump has proven excellent in practice. Particularly advantageous is the fact that the stator can be retightened so that, e.g. After some wear, an adaptation and thus an optimization of the operation is possible. On this basis, the known measures are further viable. - This is where the invention starts.
  • the invention has for its object to provide an eccentric screw pump of the type described above with improved adjustment and clamping options.
  • the invention teaches in a generic eccentric screw pump of the type described above, that the Statorspannvoriques has one or more actuators, which are connected for automated delivery of the stator to the control elements or
  • the actuators are connected to a control device or equipped with a control device, wherein the actuators are driven by the control device in dependence on state information or operating parameters of the eccentric screw pump.
  • state information or operating parameters can be made available, for example, directly from the pump or the pump controller.
  • the control device may be connected to or integrated in the pump drive or the pump drive control, the actuators being drivable by the control device, for example, depending on the power absorbed by the drive motor or the motor current.
  • a control in dependence on other parameters for example, the back pressure and / or the flow rate can be done.
  • sensors can be integrated in the eccentric screw pump, which are connected to the control device, so that the actuators can be driven by the control device as a function of measured values which are detected by the sensors, for example temperature values and / or pressure values. But it can also be used on sensors that are not part of the pump itself, but which are integrated into the system as a whole and are arranged, for example, before and / or behind the pump. Thus, for example, with a flow meter behind the pump, the flow rate can be determined or with a pressure sensor behind the pump, the back pressure can be determined.
  • the invention is based on the recognition that the function, the operation and / or the durability of an eccentric screw pump or its components can be optimized if a manual retightening of the stator is replaced or at least supplemented by an automated retightening.
  • the Statorspannvorraum is equipped with actuators that allow automated delivery. This initially makes it possible to automatically re-tension the stator after a certain operating time, ie not manually, with the aid of the drives. This process can be triggered in a targeted manner by a surgeon, for example, at certain time intervals or when recognizing decreasing efficiency, etc.
  • automated clamping is particularly preferably carried out automatically in dependence on state information or operating parameters of the eccentric screw pump.
  • the control device can consequently operate the actuators intermittently or continuously in the sense of a control or regulation as a function of state information or operating parameters.
  • the efficiency of the pump can be constantly determined and monitored by the power absorbed by the drive motor, the backpressure and / or volume flow. In case of deviation from the optimal efficiency then the delivery of the pump can be changed automatically.
  • the hydraulic power of the pump results from the flow rate on the one hand and the backpressure or differential pressure on the other hand. Both parameters can be recorded and from this the hydraulic power can be determined. This hydraulic power can then be compared with the drive power of the pump and derived from the overall efficiency.
  • the controller can switch to a specific maximum permissible starting torque
  • a control of the delivery could be effected as a function of the temperature of the stator, e.g. At a maximum allowed stator temperature, the delivery can be limited. This can improve the Statorstand
  • the core of the present invention are therefore the actuators, with which the shell segments for clamping and adjusting the stator are automatically actuated in the radial direction.
  • Such actuators may e.g. be designed as electrical or electric motor drives.
  • hydraulic drives e.g. Hydraulic cylinders or pneumatic drives, e.g. Pneumatic cylinders are used.
  • Actuators can be combined with various mechanical stator tensioning devices of the eccentric screw pump.
  • the invention can be realized, for example, in the concept known from WO 2009/024279 A1, in which the adjusting elements work as set screws and at the same time clamping screws in the radial direction on the shell segments.
  • separate drives eg electric motors, which actuate the adjusting screws in the radial direction
  • driven actuators eg stepper motors or hydraulic or pneumatic cylinders.

  • Stepper motor may e.g. to work on a corresponding actuator, which replaces the screw.
  • the clamping of the stator does not take place via radially operable adjusting elements, such as screws, but axially or axially parallel displaceable clamping elements, such as an axially displaceable clamping ring or more displaceable in the axis-parallel direction clamping segments.
  • the shell segments each have a clamping flange with first clamping surfaces on the clamping flange and the clamping flanges are one or more axially displaceable clamping elements, such as a clamping ring or more clamping segments, mounted with second clamping surfaces, wherein the first clamping surfaces and the second clamping surfaces are formed and cooperate in such a way that the stator casing can be tensioned against the stator in the radial direction in the course of an axial displacement of the clamping elements.

  • the clamping flanges are correspondingly conical, eg outside conical, formed.
  • both the first clamping surfaces and the second clamping surfaces are formed as wedge surfaces, which then optionally abut against each other on a common contact surface.
  • the re-tensioning is done by axial displacement of the clamping ring or the clamping segments and on the clamping surfaces or wedge surfaces is a deflection of the axial force in a radial clamping force. This embodiment with clamping ring or clamping segments opens up a further optimization of the automated delivery.
  • adjusting screws are also provided as adjusting elements in this embodiment, which then however work in the axis-parallel direction on the axially displaceable clamping ring or the axially displaceable clamping segments.
  • the drives already mentioned above in connection with adjusting screws can again be used and the adjusting screws can then also be replaced by corresponding actuators of the drives, so that the actuators are equipped with adjusting elements.
  • the two opposite clamping rings of the pump are connected to one another via clamping levers.
  • one or more tension levers may be connected to each tension ring, the tension levers (in pairs) e.g.

  • the clamping ring can then be provided on the outside with a toothing on the outside, onto which then e.g. an electric motor drive operates with a drive gear.
  • This embodiment can alternatively be configured so that not the clamping ring is provided with the wedge surfaces themselves with internal thread and / or external teeth, but that a separate collar or feed ring is provided with the threads and teeth described and that the clamping ring either rotatably with the Adjusting ring is connected or is also arranged rotatable relative to the adjusting ring, so that in the course of rotation of the adjusting ring of the clamping ring is not rotated, but only in the axial direction is moved.

  • these intermediate elements are volume changing pads, e.g. Hydraulic pad 41, which are arranged between the stator shell 3 and stator 1.
  • This embodiment is also useful with longitudinally divided stator. It is also possible to work with longitudinally divided stator jacket 3 or jacket segments 19. However, this embodiment can also be realized with undivided stator jacket.
  • the hydraulic pads 41 can also be automatically controlled in the sense of a remote control, so that even in such an embodiment, an adaptation of the geometry to certain operating parameters is possible.
