Einrichtung zum umwälzen des Heiz- und/oder Gebrauchswassers bei HeizkesselnDevice for circulating the heating and / or Service water for boilers
Die vorliegende Erfindung betrifft ©ine Einrichtung zum Umwälzen des Heiz- und/oder Gebrauchswassers bei Heizkesseln, bei der ein im Wasserkreislauf angeordnetes Pumpenrad von einem Motor angetrieben wird. Zum Umwälzen des Heizwassers bei Heizkesseln werden im allgemeinen sog. stopfbuchsenlose Pumpen mit Spaltrohr-Motoren verwendet. Diese Pumpen sind aber gegen Kalkablagerungen und Korrosion empfindlich, so daß sie nicht auch für Brauchwassernetze eingesetzt werden können. Die Anwendung von Pumpen mit Stopfbuchsen bringt dan Nacitoil von Leck- und Leistungsverlusten. Außerdem bedarf die Stopfbuchse von Zeit zu Zeit einer Nachstellung.The present invention relates to a device for circulating of heating and / or service water for boilers, in which an impeller arranged in the water circuit is driven by a motor. For circulating the heating water In the case of boilers, so-called glandless pumps with canned motors are generally used. These pumps but are sensitive to limescale deposits and corrosion, so that they are not also used for service water networks be able. The use of pumps with stuffing boxes results in leakage and loss of performance. In addition, the Stuffing box from time to time to be readjusted.
Es ist bei G-aa- und Wasseruhren sowie ähnlichen Meßgeräten bereits bekannt, zur Übertragung der Drehbewegung von in einer Flüssigkeit umlaufenden Seilen Magnetkräfte anzuwenden. Die vorliegende Erfindung greift diesen Gedanken auf und schlägt vor, Umwälzpumpen für das Brauch- und/oder Heizwasaer bei Heizkesseln in der Weise auszugestalten, daß Pumpenrad und Motor durch eine Membrane flüssigkeitsdicht voneinander getrennt, jedoch durch Magnetkraft, vorzugsweise kräftige Permanentmagnete, drehfest miteinander gekoppelt sind.It is on G-aa and water clocks and similar measuring instruments already known to use magnetic forces to transmit the rotary motion of ropes circulating in a liquid. The present invention takes up this idea and proposes circulating pumps for the domestic and / or Heizwasaer for boilers to design in such a way that pump impeller and the motor are sealed against each other by a membrane separated, but coupled to one another in a rotationally fixed manner by magnetic force, preferably powerful permanent magnets.
Die Membrane kann gemäß einem weiteren Schritt der Erfindung aus nichtrostendem Material, vorzugsweise aus Messing oder Edelstahl, bestehen.According to a further step of the invention, the membrane can be made of stainless material, preferably brass or Stainless steel.
Die Zeichnung zeigt als Ausführungsbeispiel des Erfindungsgegsnstandes eine Heizwasserpumpe nach der Erfindung teilweise im Schnitt.The drawing shows an exemplary embodiment of the subject matter of the invention a heating water pump according to the invention partially in section.

In dem Pumpengehäuse 1 ist das Pumpenrad 2 gelagert, dessen Welle 3 mit einer Rückβchlußplatte 4 feet verbunden ist. Auf der Öffnung des Pumpengehäusea 1 ist auf einer Dichtung 5 eine Membrane 6 angeordnet, die das Pumpengehäuse flüssigkeitsdicht abschließt. Über den Zwischenring 7 ist der Antriebsmotor 8 angeflanscht, dessen Welle 9 eine Dauermagnet» scheibe 10 trägt. Über diese Dauermagnetscheibe und die Rtt.dcschlußplatte 4 wird das Pumpenrad 2 von dem Motor 8 angetieben. In the pump housing 1, the pump wheel 2 is mounted, its Shaft 3 is connected to a return plate 4 feet. on the opening of the pump housing a 1 is on a seal 5 a membrane 6 is arranged which makes the pump housing liquid-tight concludes. The drive motor 8 is flanged on via the intermediate ring 7, the shaft 9 of which is a permanent magnet » disc 10 carries. About this permanent magnet disc and the Rtt.dcschlussplatte 4, the pump wheel 2 is driven by the motor 8.
