Abstract
Description
Technisches GebietTechnical area
Die Erfindung betrifft eine Schnecken- bzw. Exzenterschneckenpumpe, wie sie insbesondere zur Förderung von hochviskosen bzw. mit Feststoffen versetzten Medien verwendet wird.The The invention relates to a screw or eccentric screw pump, how to promote them in particular used by highly viscous or solidified media becomes.
Exzenterschneckenpumpen die dem Stand der Technik entsprechen, weisen meist einen feststehenden äußeren Stator und einen darin laufenden Rotor auf. Der Antrieb des Rotors erfolgt meist durch einen externen Elektromotor, welcher mittels einer Gelenk- bzw. Biegewelle mit dem Rotor verbunden ist. In den nachfolgenden Ausführungen wird zwischen Schnecken- und Exzenterschnekkenpumpen nicht weiter unterschieden, da dies keine Auswirkungen auf das der Erfindung zugrundeliegende Prinzip hat.Progressive cavity pumps which correspond to the prior art, usually have a fixed outer stator and a rotor running therein. The drive of the rotor takes place usually by an external electric motor, which by means of a joint or bending shaft is connected to the rotor. In the following versions will not continue between worm and eccentric worm pumps as this does not affect the invention underlying principle has.
Bekannte Exzenterschneckenpumpen weisen jedoch eine lange Bauform auf und sind aufgrund der hohen Anzahl beweglicher Teile in Motor, Gelenkwelle und Pumpe wartungsbedürftig. Zudem ist bei einer solchen Anordnung auf mindestens einer Seite der Pumpe eine Abdichtung zur Gelenkwelle hin notwendig.Known However, progressing cavity pumps have a long design and are due to the high number of moving parts in the engine, PTO shaft and pump in need of maintenance. In addition, in such an arrangement on at least one side of the Pump a seal to the PTO shaft necessary.

Darstellung der ErfindungPresentation of the invention
Der Erfindung liegt die Aufgabe zugrunde, eine Exzenterschneckenpumpe derart zu gestalten, dass das zum Antrieb der Pumpe benötigte Drehmoment ohne zusätzliche, die Bauform der Pumpe verlängernde Mittel sowie ohne Wellendichtungen und Wellenlagerungen zugeführt werden kann und gleichzeitig die Pumpe auch für hohe Drücke geeignet ist.Of the Invention is based on the object, a progressing cavity pump to make such that the torque required to drive the pump without additional, extend the design of the pump Medium and can be supplied without shaft seals and shaft bearings and at the same time the pump is also suitable for high pressures.

Eine
weitere vorteilhafte Ausgestaltung der Erfindung besteht darin,
dass der Motor aus Läufer
Eine
Steuereinheit ist zur Steuerung der entsprechenden Teile der Statorwicklung
Zur richtigen Ansteuerung der Spulen ist vorzugsweise ein Positionssensor vorgesehen, der die exakte Position des Rotors bzw. des Läufers in Bezug auf den Stator sgnalisiert. Ein solcher Positionssensor kann beispielsweise auch mit Hilfe der in den Rotor integrierten Magnete realisiert werden.to correct control of the coils is preferably a position sensor provided that the exact position of the rotor or the rotor in Related to the stator. Such a position sensor can For example, with the help of the integrated magnets in the rotor will be realized.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung ist der Motor in Form eines Asynchronmotors ausgelegt. Hierzu ist der Läufer als Widerstandsläufer bzw. vorzugsweise als Kurzschlussläufer ausgebildet. Weiterhin sind in der Statorwicklung Wicklungen zur Erzeugung eines Drehfeldes vorgesehen. Durch das Drehfeld werden in den Rotorwicklungen bzw. in der leitenden Rotorstruktur Spannungen induziert, welche je nach dem elektrischen Widerstand der Wicklungen bzw. der leitenden Rotorstruktur zu entsprechenden Strömen führen. Diese Ströme verursachen wiederum ein Magnetfeld und damit ein Drehmoment. Zur Ansteuerung der Wicklungen ist eine optionale Steuerschaltung, vorteilhafterweise ein Frequenzumrichter, zur Erzeugung der phasenverschobenen Signale variabler Frequenz zur Erzeugung eines Drehfeldes mit der gewünschten Drehfrequenz vorgesehen.In a further advantageous embodiment of the invention is the Motor designed in the form of an asynchronous motor. For this purpose, the runner as resistance runner or preferably designed as a squirrel cage rotor. Farther are in the stator winding windings for generating a rotating field intended. Due to the rotating field in the rotor windings or induced in the conductive rotor structure voltages, whichever the electrical resistance of the windings or the conductive rotor structure to corresponding currents to lead. These streams in turn cause a magnetic field and thus a torque. to Control of the windings is an optional control circuit, advantageously a frequency converter, for generating the phase-shifted signals variable frequency for generating a rotating field with the desired rotation frequency intended.
Wahlweise können in dem Rotor Nuten zur Aufnahme von Rotorwicklungen vorgesehen sein.Optional can be provided in the rotor grooves for receiving rotor windings.
Eine
andere Ausgestaltung der Erfindung sieht vor, dass in dem Läufer
In einer weiteren vorteilhaften Ausgestaltung der Erfindung sind die magnetischen Komponenten bzw. Permanentmagnete im Läufer sowie die Spulen im Stator derart angeordnet, dass eine vorgegebene Kraft in axialer Richtung auf den Rotor ausgeübt wird. Besonders vorteilhaft ist es, wenn die axiale Kraft mit gleicher Stärke dem Pumpendruck entgegenwirkt. Zur Überwachung der Rotorposition wird vorzugsweise ein Lagerregler eingesetzt, der die Position des Rotors mit Hilfe wenigstens eines Positionssensors steuert.In a further advantageous embodiment of the invention are the magnetic components or permanent magnets in the rotor as well the coils are arranged in the stator such that a predetermined force is exerted on the rotor in the axial direction. Especially advantageous it is when the axial force with the same strength counteracts the pump pressure. For monitoring the rotor position, a bearing controller is preferably used, which controls the position of the rotor by means of at least one position sensor.
Eine weitere Ausgestaltung der Erfindung sieht einen Rotor vor, der durch die axiale Kraft in Axialrichtung verschiebbar ist. Durch eine solche Verschiebbarkeit kann die Verringerung des Losbrechmoments beim Pumpenanlauf erreicht werden. Ebenso kann dadurch beispielsweise der Pumpenauslass durch den Rotor selbst verschlossen werden. Alternativ kann selbstverständlich auch durch die axiale Bewegung des Rotors ein Ventilkörper betätigt werden. Dies ermöglicht insbesondere bei Dosierpumpen eine besonders feine und nachlauffreie Dosierung.A Another embodiment of the invention provides a rotor before, by the axial force is displaceable in the axial direction. By such Displaceability can reduce the breakaway torque when Pump start can be achieved. Likewise, this can for example the pump outlet be closed by the rotor itself. alternative of course also be actuated by the axial movement of the rotor, a valve body. this makes possible especially for dosing pumps a particularly fine and follow-up dosing.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung sind Spulen im Läufer entgegengesetzt zu den Spulen gepolt, die das Drehmoment auf den Rotor übertragen. Durch diese steuerbare Umkehrpolung wird im Rotor eine Kraft erzeugt, die entgegen der Strömungsrichtung des gepumpten Mediums wirkt und damit die vom Medium erzeugten hydraulischen Kräfte auf die Stirnseiten des Rotors kompensiert oder reduziert. Die notwendige Anzahl der umgekehrt gepolten Spulen kann dem erzeugten Förderdruck variabel angepasst werden.In A further advantageous embodiment of the invention are coils in the runner poled opposite to the coils that transmit the torque to the rotor. This controllable reverse polarity generates a force in the rotor, the opposite to the flow direction of the pumped medium and thus the hydraulic generated by the medium personnel compensated or reduced to the end faces of the rotor. The necessary Number of reversed poled coils can the generated discharge pressure be adjusted variably.
