Abstract
Description
Die Erfindung betrifft ein Pumpenaggregat für Heizungsanlagen gemäß den im Oberbegriff des Anspruches 1 angegebenen Merkmalen.The invention relates to a pump unit for heating systems according to the features specified in the preamble of claim 1.
Mit zunehmend günstiger werdenden Elektronikbauteilen werden Kreiselpumpen dieser Art auch zunehmend in unteren Leistungsklassen eingesetzt. Solche Aggregate weisen typischerweise einen elektronischen Drehzahlsteller, z. B. einen Frequenzumrichter oder eine Phasenanschnittsteuerung sowie eine Drehzahlregelung auf. Ein solches Aggregat kann aufgrund der Drehzahlvarianz weite Leistungsbereiche abdecken, bedarf jedoch hinsichtlich der Einstellung und somit Anpassung an die vorhandene Heizungsanlage geschulten Fachpersonals. Zur Einstellung sind in der Regel entsprechende Stellglieder am Aggregatgehäuse vorhanden. Auch ist es aus EP 0 664 399 A1 bekannt, zusätzlich zu den am Aggregat selbst vorgesehenen Stellgliedern eine drahtlose Fernbedienung vorzusehen, mit der diese Einstellungen vorgenommen werden können.With increasingly cheaper electronic components Centrifugal pumps of this type are also increasingly being used in the lower performance classes used. Such units typically have an electronic one Speed controller, e.g. B. a frequency converter or Phase control and speed control. Such one Due to the speed variance, the unit can cover a wide range of performance cover, but needs with regard to the setting and thus adaptation to the existing heating system trained specialist personnel. Appropriate actuators are usually used for setting present on the unit housing. It is also from EP 0 664 399 A1 known, in addition to the actuators provided on the unit itself to provide a wireless remote control with which this Settings can be made.
Insbesondere Heizungspumpenaggregate kleiner Leistung sind Großserienprodukte, die beispielsweise in zigtausendfacher Stückzahl täglich produziert werden. Bei Produkten dieser Art ist man naturgemäß bemüht, die Modellvielfalt so gering wie möglich zu halten, um die Herstellungskosten weiter zu senken. Dies bedingt jedoch, daß das Pumpenaggregat, das Modelle unterschiedlicher Ausstattung ersetzen soll, sämtliche "features" aller damit abzudeckenden Aggregate umfassen muß. Andererseits ist es bekannt, daß einfache Heizungspumpenaggregate auch vom Nicht-Fachmann oder vom Fachfremden, wie beispielsweise einem Elektroinstallateur, eingebaut werden. Auch in diesem Fall muß sichergestellt sein, daß das Aggregat zuverlässig und bestimmungsgemäß arbeitet, ohne daß sich der Anwender erst mit komplizierten Kennfeldern und entsprechenden Einstellmöglichkeiten befassen muß.Small-capacity heating pump units in particular are large-scale products, for example in tens of thousands are produced daily. With products of this kind you are natural endeavors to keep the variety of models as small as possible in order to further reduce manufacturing costs. However, this requires that the Pump unit, which replace models of different equipment should include all "features" of all units to be covered got to. On the other hand, it is known that simple heating pump units also by the non-specialist or by a non-specialist, such as for example, an electrician. Also in In this case, it must be ensured that the unit is reliable and works as intended without the user having to deal with complicated maps and corresponding setting options must deal with.
Vor diesem Hintergrund liegt der Erfindung ausgehend von dem einleitend beschriebenen Stand der Technik die Aufgabe zugrunde, ein Pumpenaggregat zu schaffen, das einerseits den Anforderungen eines von moderner Elektronik unterstützten Pumpenaggregats genügt, andererseits jedoch auch ohne langwierige Einstellungen als Standardaggregat einsetzbar ist.Against this background, the invention is based on that state of the art described in the introduction based on the task to create a pump set that meets the requirements on the one hand a pump unit supported by modern electronics is sufficient, on the other hand, however, without lengthy settings as a standard unit can be used.
Diese Aufgabe wird gemäß der Erfindung durch die in Anspruch 1 aufgeführten Merkmale gelöst.This object is achieved according to the invention by the one in claim 1 listed features solved.
Demgemäß sieht die Erfindung vor, das Pumpenaggregat auf eine Drosselkurve (wenn es sich um ein Aggregat lediglich mit einer Steuerung handelt) bzw. einer Regelkurve (wenn es sich um ein Aggregat mit Regelung handelt) vorzugsweise werkseitig voreinzustellen und im übrigen eine Änderung dieser Einstellung ausschließlich über eine separate Einstellvorrichtung durchzuführen. Mit der erfindungsgemäßen Lösung ist es somit möglich, ein Pumpenaggregat mit mannigfaltiger elektronischer Ausstattung auch für einfachste Anwendungen bereitzustellen, ohne daß dem Anwender die sonst eher komplizierte Einstellung dieses Aggregates aufgebürdet wird, gleichwohl jedoch mit demselben Aggregat ein modernes elektronisch gesteuertes bzw. geregeltes Pumpenaggregat zur Verfügung zu stellen, das in Verbindung mit der separaten Einstellvorrichtung an die individuellen Erfordernisse anpaßbar ist. Durch die werkseitige Voreinstellung auf eine Drosselkurve bzw. eine Regelkurve kann das Aggregat gehandhabt werden wie ein Pumpenaggregat ohne Steuerelektronik bzw. mit fest eingestellter Regelkurve. Wenn also beispielsweise in einer Heizungsanlage ein "einfaches" Pumpenaggregat ausfällt und zu ersetzen ist, ist lediglich auf die Leistungsangabe am Typenschild zu achten, um Ersatz zu beschaffen und das defekte gegen ein neues Aggregat auszutauschen. Die dabei innerhalb des neuen Aggregates befindliche Leistungselektronik und die dadurch gegebenen Einstellmöglichkeiten sind für den Anwender völlig ohne Belang, da das Aggregat auf die angegebene Leistung durch Wahl der Steuer-/Regelkurve werkseitig voreingestellt ist. Andererseits kann der Fachmann das gleiche Aggregat mit Hilfe der Einstellvorrichtung auch bei Anwendungen einsetzen, die eine Steuerung der Drehzahl, insbesondere eine Regelung derselben erfordern. Über die Einstellvorrichtung kann er das Aggregat entsprechend konfigurieren, d. h. an die Erfordernisse der Heizungsanlage anpassen.Accordingly, the invention provides that the pump unit on a Throttle curve (if it is an aggregate with only one Control) or a control curve (if it is a Unit with control) is preferably preset at the factory and otherwise a change in this setting only to be carried out via a separate setting device. With the invention Solution, it is therefore possible to use a pump set diverse electronic equipment even for the simplest applications to provide without the user the otherwise rather complicated Setting this aggregate is burdened, nonetheless but with the same unit a modern electronically controlled one or to provide a regulated pump unit, which in Connection with the separate adjustment device to the individual Requirements is customizable. By the factory setting on the unit can handle a throttle curve or a control curve are like a pump set without control electronics or with fixed control curve. So if, for example, in a heating system a "simple" pump unit fails and has to be replaced is only to pay attention to the power rating on the type plate, to get replacement and the defective against a new unit exchange. The one inside the new unit Power electronics and the resulting setting options are completely irrelevant to the user, since the unit is based on the specified power by selecting the control curve in the factory is preset. On the other hand, the person skilled in the art can use the same unit with the help of the setting device also for applications use a control of the speed, especially a regulation require the same. He can do that using the setting device Configure the aggregate accordingly, d. H. to the requirements of Adapt heating system.
Die Einstellvorrichtung kann entweder leitungsgebunden oder aber, was bevorzugt der Fall sein wird, drahtlos, d. h. über eine Infrarot- oder Funkverbindung mit dem Pumpenaggregat in Verbindung stehen. Im Falle der drahtgebundenen Verbindung kann am Aggregat beispielsweise im Klemmenkasten eine Steckeraufnahme vorgesehen sein, solche Steckeraufnahmen sind hinlänglich bekannt, z. B. für die Aufnahme von Diagnosesteckern.The setting device can either be wired or which will preferably be the case wireless, i. H. via an infrared or Radio connection to the pump set. In the case of a wired connection, for example, on the unit a connector receptacle may be provided in the terminal box, such connector receptacles are well known, for. B. for the Inclusion of diagnostic plugs.
Wenn hingegen die Einstellvorrichtung drahtlos mit dem Pumpenaggregat kommunizieren soll, so setzt dies vorrichtungsseitig einen Sender und aggregatseitig einen Empfänger voraus. Bevorzugt wird die Einstellvorrichtung jedoch Sender und Empfänger aufweisen, ebenso wie das Pumpenaggregat, damit sie gleichzeitig auch als Kontrollvorrichtung ausgebildet sein kann, um Betriebsdaten des Pumpenaggregats zu empfangen, ggf. zu speichern und anzuzeigen. Es wird in diesem Zusammenhang insbesondere auf EP 0 664 399 A1 verwiesen, in der eine solche Steuer- und Kontrollvorrichtung im einzelnen beschrieben ist.If, on the other hand, the setting device is wireless with the pump set to communicate, this uses one on the device side Sender and aggregate one receiver ahead. Is preferred however, the setting device has a transmitter and a receiver, as well as the pump unit, so that they can also be used as Control device can be configured to the operating data of the To receive the pump set, save it and display it if necessary. It in this context, in particular EP 0 664 399 A1 referred in which such a control and monitoring device in individual is described.
Um sicherzustellen, daß das Pumpenaggregat nicht versehentlich von anderen Sendeeinrichtungen, beispielsweise Funkfernbedienungen für Garagentore, Infrarot-Fernbedienungen für Fernseher, Funktelefonen etc. eingestellt wird, wird das zwischen Einstellvorrichtung und Pumpenaggregat gesendete Signal zweckmäßigerweise codiert. Die Codierung wird insbesondere bei digitaler Übertragung vorzugsweise durch einen jedem Befehlssignal vorangestellten Schlüssel oder in anderer geeigneter Weise erfolgen. Solche Signalverschlüsselungen an sich sind hinlänglich bekannt.To ensure that the pump set is not inadvertently from other transmission devices, for example radio remote controls for Garage doors, infrared remote controls for televisions, radio telephones etc. is set, it will be between the adjusting device and the pump unit transmitted signal conveniently coded. The coding is preferred, especially in the case of digital transmission a key preceding each command signal or in another appropriately. Such signal encryption in itself are well known.
Da die Einstellvorrichtung ausschließlich für vom Fachmann durchzuführende Einstellungen vorgesehen ist, kann das Pumpenaggregat in einfacher Ausführung (als werkseitig voreingestelltes Aggregat) kostengünstig ohne eine solche Einstellvorrichtung angeboten werden. Andererseits wird es, da die vorzunehmenden Einstellungen ausschließlich dem Fachmann vorbehalten sein sollen, genügen, wenn dieser eine Einstellvorrichtung erwirbt, da er mit dieser jedes Pumpenaggregat eines bestimmten Typs oder unterschiedlicher Typen (je nach Auslegung) einstellen kann. Insofern wird sich also ein weiterer Kostenvorteil ergeben, da selbst für diesen anforderungsintensiven Anwendungsfall nicht für jedes Pumpenaggregat eine Einstellvorrichtung bereitzustellen ist, sondern mit einer einzigen Einstellvorrichtung beliebig viele Pumpenaggregate einstellbar sind. Darüberhinaus ergibt sich ein weiterer Kostenvorteil in der Herstellung dadurch, daß auf die sonst übliche am Pumpenaggregat befindliche Einstellvorrichtung vollständig verzichtet wird. Dies ist auch hinsichtlich der Zuverlässigkeit des Aggregates von Vorteil, da gerade im Bereich der Einstellvorrichtung, wo zahlreiche Schalter bzw. Kontakte vorgesehen sind, es leicht zu Störungen kommen kann. Eine solche potentielle Störquelle ist damit von vornherein ausgeschlossen.Since the setting device is only to be carried out by a specialist The pump set can be adjusted simple design (as a factory-set unit) be offered inexpensively without such an adjusting device. On the other hand, since the settings to be made are exclusive should be reserved for the specialist, suffice if this acquires an adjusting device, since it can be used with each pump unit of a certain type or different types (each according to the design). In this respect, there will be another one Cost advantage result because even for this demanding requirements Not one setting device for every pump unit is to be provided, but with a single adjusting device any number of pump units can be set. Furthermore there is a further cost advantage in production because that to the otherwise usual adjustment device located on the pump unit is completely dispensed with. This is also regarding the Reliability of the unit is an advantage, especially in the area of Adjustment device where numerous switches or contacts are provided are, it can easily cause interference. Such a potential A source of interference is therefore excluded from the outset.
Um sicherzustellen, daß die werkseitigen Voreinstellungen auch nach dem Ausbau eines Pumpenaggregates stets wiederhergestellt sind, ist innerhalb des Klemmenkastens ein Schalter/Taster vorgesehen, der dann betätigt wird, wenn der Deckel des Klemmenkastens entfernt bzw. aufgesetzt wird. Dies ist regelmäßig dann erforderlich, wenn die elektrische Versorgungsleitung an- bzw. abgeklemmt wird. Dieser Reset-Schalter stellt somit sicher, daß bei Ein- bzw. Ausbau eines Pumpenaggregates in einer Heizungsanlage, wobei stets ein elektrisches Anschlußkabel im Klemmenkasten an- bzw. abzuklemmen ist, die werkseitige Voreinstellung wieder erreicht wird. Auf diese Weise kann sichergestellt werden, daß auch ein Pumpenaggregat, das schon einmal in einer Heizungsanlage eingebaut war und einer anderen Verwendung zugeführt werden soll, wieder die ursprünglichen werkseitig erfolgten Voreinstellungen aufweist und somit wieder der anfänglichen breiten Anwendungspalette zur Verfügung steht.To ensure that the factory presets also after the removal of a pump set are always restored a switch / button is provided inside the terminal box is then operated when the cover of the terminal box is removed or put on. This is regularly necessary if the electrical supply line is connected or disconnected. This Reset switch thus ensures that when installing or removing a Pump unit in a heating system, always an electrical one Connect or disconnect the connection cable in the terminal box, the factory setting is reached again. In this way can be ensured that a pump unit that already was installed in one heating system and another Use should be returned to the original factory has been made and thus the initial settings wide range of applications is available.
Bevorzugt erfolgt eine werkseitige Voreinstellung so, daß das Pumpenaggregat im Bereich zwischen 80 % und 100 % der maximalen Leistung betrieben wird. Eine solche Einstellung gewährleistet, daß das Aggregat mit vergleichsweise hohen Wirkungsgrad betrieben wird, wenn die werkseitige Voreinstellung beibehalten bleibt. Darüberhinaus steht eine hohe Pumpenleistung zur Verfügung. Von der Maximalleistung nach unten hin abweichen wird die werkseitige Voreinstellung dann, wenn das Aggregat in diesem Bereich nicht dauerlastfest ist oder wenn eine gewisse Sicherheit gegen thermische oder sonstige Überlastung gegeben sein soll. A factory setting is preferably carried out so that the pump unit in the range between 80% and 100% of the maximum Performance is operated. Such an attitude ensures that the unit is operated with comparatively high efficiency, if the factory default setting is retained. Furthermore high pump output is available. From the maximum power The factory setting will deviate downwards when the unit is not resistant to permanent loads in this area or if there is some security against thermal or other Overload should be given.

Mindestens ein Teil des Gehäuses ist zum Zwecke der elektrischen Verbindung mit dem Versorgungsnetz durch einen Deckel abgeschlossen. Der Deckel ist durch Schrauben gesichert und nach Entfernen der Schrauben kann der Deckel abgehoben werden, so daß die Anschlußklemmen zugänglich sind. Der vorerwähnte Reset-Schalter ist als Taster, und zwar als Öffner ausgebildet, der bei geschlossenem Deckel geschaltet, d. h. in seiner Öffnungsstellung verbleibt. Durch Abnahme des Deckels gelangt der Taster federkraftbeaufschlagt in seiner Ausgangsstellung zurück, in der die Kontakte elektrisch leitend miteinander verbunden sind. Die entsprechende Rücksetzung der Voreinstellungen erfolgt dadurch, daß durch einen Kurzschluß der Kontakte ein Speicher gelöscht wird, der die über die Eingabevorrichtung eingegebenen Einstellungen enthält.A conventional pump unit according to the invention consists of a Discharge port and a suction port with a housing in between, in the centrifugal pump and motor in the usual way coaxial are arranged one behind the other.
