Pumpe pump mit einem in einem with one in one Gehäuse casing befestigten Elektro-attached electrical

motorengine

Die Erfindung betrifft eine elektromotorisch getriebene Pumpe mit einem in einem Gehäuse befestigten Elektromotor, der einen permanent magnetischen ersten Polring antreibt, welcher zusammen mit einem zweiten permanent- oder weichmagnetischen Polring eine magnetische Kupplung bildet, wobei das Pumpenlaufrad mit dem zweiten Polring eine Einheit bildet und bei dem zwischen den Polringen ein magnetisch durchlässiger Wandbereich eines Pumpengehäuses verläuft.The invention relates to an electric motor driven Pump with an electric motor fixed in a housing, which has a permanently magnetic first pole ring drives, which together with a second permanent or soft magnetic pole ring creates a magnetic Coupling forms, the pump impeller forming a unit with the second pole ring and the one between A magnetically permeable wall area of a pump housing runs along the pole rings.

Pumpen nach der Erfindung sind insbesondere für die Umwälaung von Heizungswasser vorgesehen.Pumps according to the invention are particularly intended for circulating heating water.

Heizungsumwälzpumpen werden entweder mit Wellenabdichtungen ausgebildet oder als sogenannte Spaltrohrpumpen gebaut.Heating circulation pumps are either designed with shaft seals or as so-called canned pumps built.

Wellenabgedichtete Pumpen leiden früher oder späterShaft-sealed pumps suffer sooner or later

an Leckströmen, die insbesondere bei sogenannten hermetisch geschlossenen Heizungsanlagen, die anstelle eines Hochbehälters einen Membrandruckbehälter besitzen, sehr bald zum Ausfall solcher Heizungsanlagen führen.to leakage currents, especially in so-called hermetically sealed heating systems that take place of an elevated tank have a diaphragm pressure vessel, very soon to the failure of such heating systems to lead.

Spaltrohrpumpen dagegen haben den Nachteil, daß die Lager des Motors vom Wärmeträger-Wasser geschmiert werden. Dieses Wasser führt jedoch in der Regel Schmutzteile, insbesondere Rost oder Hammerschlag, was früher oder später zu Reibgeräuschen in den Lagern und damit zu akustischen Störungen öder auch zum Blockieren der Pumpe führt.Canned pumps, on the other hand, have the disadvantage that the motor bearings are lubricated by the heat transfer water. However, this water usually carries debris, especially rust or hammer blows, which used to be or later to friction noises in the bearings and thus to acoustic disturbances or to blocking the pump leads.

Als besonders vorteilhaft haben sich magnetische Übertragungssysteme für die Verwendung in Pumpen erwiesen, da damit der Wasserkreislauf von dem Motorraum völlig abtrennbar ist. Bei diesen Pumpen erfolgt der Antrieb durch konventionelle Elektromotoren, die mit langlebiger Schmierung ausgebildet werden können. Der Nachteil des Betriebs von Heizungsumwälzpumpen mit Elektromotoren besteht in diesem Fall jedoch darin, daß sowohl die Wicklung als insbesondere auch die Lager ständig einer hohen, durch das Heizungswasser bedingten Temperatur ausgesetzt sind, wodurch das Schmiermittel verdunstet oder aus dem Lager herauskriecht oder sehr schnell altert.Magnetic transmission systems have proven to be particularly advantageous for use in pumps, since the water circuit can thus be completely separated from the engine compartment. These pumps are driven by conventional electric motors, which can be designed with long-lasting lubrication. The disadvantage of the Operation of heating circulation pumps with electric motors in this case, however, consists in the fact that both the Winding and especially the bearings are constantly at a high temperature caused by the heating water are exposed, causing the lubricant to evaporate or creep out of the bearing or very quickly ages.

Die Erfindung vermeidet diesen Nachteil, indem der vom Motor angetriebene magnetische Polring gleichzeitig mit Lüfterflügeln ausgebildet wird und damit eine Luftkühlung des Motors bewirkt. Dies setzt jedoch voraus, daß eine thermische Isolation zwischen dem Motor und dem Pumpengehäuse vorgesehen wird, da sonst nicht nur die \erlustwärme des Motors abgeführt werden müßte,The invention avoids this disadvantage by having the magnetic pole ring driven by the motor at the same time Fan blades is formed and thus causes air cooling of the engine. However, this assumes that thermal insulation between the motor and the pump housing is provided, otherwise not only the \ loss heat of the engine would have to be dissipated,

sondern auch ein Wärmestrom, der aus dem Heizungswasser stammt. but also a heat flow that comes from the heating water.

Die Erfindung soll anhand einer Figur erläutert werden.The invention is to be explained with reference to a figure.

Der Motor a, b ist in einem Motorgehäuse d unter Zwischenschaltung von gummielastischen Ringen c und c1 eingespannt und treibt den magnetischen Polring e an. Durch eine magnetisch durchlässige Trennwand f hindurch wird der angetriebene Polring m in Umdrehung versetzt, der mit dem Pumpenlaufrad η eine Einheit bildet. Der Abstand zwischen der Wandung f und dem Polring e wird so groß gewählt, daß bei den größten betriebsmäßigen Schwingungen, die der Motor a, b in seiner gummielastischen Aufhängung auszuführen vermag, keine Berührung stattfindet. Der Motor ist kugelgelagert» In das Motorgehäuse d ist ein Zwischenboden j eingesetzt, der zur Führung der Kühlluft dient.The motor a, b is clamped in a motor housing d with the interposition of rubber elastic rings c and c 1 and drives the magnetic pole ring e. The driven pole ring m, which forms a unit with the pump impeller η, is set in rotation through a magnetically permeable partition f. The distance between the wall f and the pole ring e is chosen to be so large that there is no contact with the greatest operational vibrations that the motor a, b is able to carry out in its rubber-elastic suspension. The motor is mounted on ball bearings »An intermediate floor j is inserted into the motor housing d, which serves to guide the cooling air.

Die Kühlung wird durch die Schaufeln k bewerkstelligt. Die Kühlluft strömt nach erfolgter Motorkühlung am magnetischen Polring e vorbei und tritt durch die Öffnungen ο aus. Die Verbindungen zwischen dem heißen Pumpengehäuse ρ und dem Motor werden vorzugsweise durch die Wärme schlecht leitende Ringe 1 vorgenommen, damit der Motor und das Motorkugellager nicht durch das heiße Wasser aufgeheizt werden.The cooling is brought about by the blades k. After the engine has cooled down, the cooling air flows through the magnetic pole ring e and exits through the openings ο. The links between the hot Pump housing ρ and the motor are preferably made by the heat poorly conductive rings 1, so that the motor and the motor ball bearing are not heated up by the hot water.
