Umwälzpumpe, welche von einem Elektromotor betrieben wirdCirculation pump operated by an electric motor

Die Erfindung bezieht sich auf eine von einem Elektromotor betriebene Umwälzpumpe« Bei derartigen Pumpen ist- es üblich, den antreibenden Motor direkt im Kreislauf des zu fördernden Mediums unterzubringen. Der Läufer des M.tors ist dabei Teil der Pumpe. Ec ist zu diesem Zweck mit einem Pumpenrad versehen j welches entweder an seinem Ende oder in seinem Inneren angebracht isto Als Antriebsmotoren werden Asynchronmotoren verwendet * Der Standes? und die Ständerwicklung werden gegen das au fördernde Medium, bei welchem es sich im allgemeinen uia Heißwasser handelt , durch ein in den Luftspalt zwischen Laufor und Ständer eingeführtes Hohr, welches mit dem Ständer verbunden wird, geschützt. Der Läufer, bei welchem es sich ua einen Kurzschlußläufer handelt, ist hingegen nicht gegen das Medium geschützt. Es hat sich nun herausgestellt, daß box längerer Betriebszeit und auch insbesondere nach längeran Stillstandspausen der Laufer von dem Medium angegriffen wird« Er fängt an zu korrodieren, und es treten VerklemmungenThe invention relates to one of an electric motor operated circulating pump “With pumps of this type, it is common practice to have the driving motor directly in the circuit of the pumped To accommodate the medium. The rotor of the M.tors is part of the pump. For this purpose Ec is provided with an impeller j which either at its end or inside it asynchronous motors are used as drive motors used * The class? and the stator winding are against the au promoting medium, in which it is generally uia hot water, through an air gap between Laufor and stand inserted Hohr, which with the stand connected, protected. The runner in which it is inter alia a squirrel cage is, however, is not against the medium protected. It has now been found that the box has been in operation for a longer period of time and, in particular, after a long period of time Standstill breaks of the runners attacked by the medium will «It starts to corrode and deadlocks occur

weiterhin einen hohen Wirkungsgrad und somit eine geringe Eigenerwärmung« was seinen Einsatz auch bei hohen Temperaturen des zu fördernden Mediums ermöglicht. Weiterhin kann der Luftspalt durch den verwendeten Oxydmagneten, welcher eine hohe Koerzitivkraft hat, groß gehalten werden., was wegen des im Luftspalt liegenden Spaltrohres erforderlich ist, ohne daß der Motor dadurch wesentlich verschlechtert wird. Auch hierdurch wird der Wirkungsgrad der gesamten Anordnung verbessert.continues to have a high degree of efficiency and thus a low one Self-heating «which enables its use even at high temperatures of the medium to be conveyed. Furthermore can the air gap through the oxide magnet used, which has a high coercive force, must be kept large. what Required because of the can in the air gap without significantly deteriorating the engine will. This also improves the efficiency of the entire arrangement.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.An embodiment of the invention is shown in the drawing shown.

Mit 1 ist des Pumpengehäuse bezeichnet, durch welches das zu fördernde Medium in Sichtung der Pfeile 8 und 9 hindurchtritt/ Das Pumpenrad 2 besitzt einen rohrförmigen Ansatz 10, auf welchem der Magnet 3 des Läufers angebracht ist und in welchen die feststehende Achse 4 hineinragt« Sas Ständerpaket ist Bit 5 bezeichnet und trägt die Ständerwicklung 11. Zwischen Läufer und Ständer ist der Spalttopf 6 angebracht, Kelcher die feste Achse 4- trägt. Dieser Spalttopf iet mit dem Pumpengehäuse 1 verbunden und schirmt somit den Ständer gegen das zu fördernde Medium ab.

Der bürstenlose Universalmotor ist wie folgt aufgebaut· Ep besitzt einen dauermagnetischen Läufer, welcher» wie solion erwähnt, aus korrosionsbeständigem Material, insbesondere aus oxydischem Material,besteht. Die Speisung und Steuerung der Ständerspulen erfolgt über Transistoren. Sie für die Stromdurchlässigkeit der Transistoren erforderlichen Zündimpulse werden in Abhängigkeit von der Lauferstellung über einen Steuerkreis an die Gitter der Transistoren gegeben. Als Steuerkreis können Hallgeneratoren aber auch Hochfrequenzoszillatoren verwendet werdenοThe universal brushless motor is constructed as follows · Ep has a permanent magnet runner, which »like solion mentioned, made of corrosion-resistant material, in particular made of oxidic material. The supply and control the stator coils are made via transistors. They are required for the current permeability of the transistors Ignition pulses are sent to the grids of the transistors via a control circuit depending on the setting of the barrel. Hall generators can also be used as a control circuit, but also high-frequency oscillators be used ο
