Abstract
Description
Die Erfindung bezieht sich auf Überwachungseinrichtung für ein Membranausdehnungsgefäß.The The invention relates to monitoring equipment for a Diaphragm expansion vessel.
Membranausdehnungsgefäße werden vorzugsweise in der Heizungstechnik dazu verwendet, die Volumenausdehnung des Wassers bei Erhitzung zu kompensieren. Hierzu besteht das Membranausdehnungsgefäß aus einem Wasserraum und einem Gasraum, welche durch eine Membran voneinander getrennt sind. Der Gasraum besteht im Allgemeinen aus ein Stickstoffpolster. Der Wasserraum wird beispielsweise mit dem Heizungsnetz verbunden. Steigt der Wasserdruck an, so dehnt sich das Wasser aus, die Membran dehnt sich in Richtung des Gaspolsters aus und komprimiert somit das Gaspolster im Gasraum.Become a membrane expansion vessel preferably used in heating technology, the volume expansion of the water when heated to compensate. For this purpose, the membrane expansion vessel consists of a Water space and a gas space, which are separated by a membrane are. The gas space generally consists of a nitrogen cushion. The water space is connected, for example, with the heating network. If the water pressure rises, the water expands, the membrane expands in the direction of the gas cushion and thus compresses the gas cushion in the gas space.
Wird die Membran spröde, so kann Wasser in den Gasraum eindringen und Stickstoff aus dem Gasraum in den Wasserraum eintreten. Im ungünstigsten Fall befindet sich kein Stickstoff mehr im Gasraum. Dehnt sich nun das Wasser auf Grund von Erhitzung auf, so nimmt der Druck im System erheblich zu. Hierdurch kann es zur Beschädigung von Bauteilen oder Wasserschäden im Aufstellraum kommen.Becomes the membrane is brittle, This allows water to enter the gas space and nitrogen from the gas space enter the water area. In the worst case is no more nitrogen in the gas space. Now the water expands on the ground from heating up, the pressure in the system increases considerably. hereby it can damage it of components or water damage come in the installation room.
Der Erfindung liegt daher die Aufgabe zugrunde, mittels einer Überwachungseinrichtung einen Verschleiß der Membran feststellen zu können, um hierdurch entsprechende Wartungsmaßnahmen rechtzeitig einleiten zu können.Of the The invention is therefore based on the object by means of a monitoring device a wear of Membrane to be able to determine thereby promptly initiate appropriate maintenance measures to be able to.
Diese Aufgabe wird mittels einer Überwachungseinrichtung für ein Membranausdehnungsgefäß gemäß dem Anspruch 1 dadurch gelöst, dass im Gasraum ein Sensor angeordnet ist, welcher das Vorhandensein von Wasser erkennen kann. Wird die Membran brüchig und Wasser dringt in den Gasraum ein, so gelangt auch Wasser an den Sensor, welcher dies erkennt und ein entsprechendes Signal weiterleiten kann. Die Elektroden des Sensors sollen über Leitungen mit einer Überwachungselektronik verbunden sein. Der Sensor mit seinen zwei Elektroden ist dazu geeignet, die Leitfähigkeit zwischen den Elektroden zu messen. Während Stickstoff im Spalt zwischen den Elektroden quasi als Isolator anzusehen ist, ist Wasser ein leitendes Medium.These Task is by means of a monitoring device for a Membrane expansion vessel according to the claim 1 solved by that in the gas space, a sensor is arranged, which the presence of water. The membrane becomes brittle and water penetrates into the Gas space, so also gets water to the sensor, which this recognizes and can forward a corresponding signal. The electrodes of the sensor should be via wires with a monitoring electronics be connected. The sensor with its two electrodes is suitable for the conductivity between the electrodes. While nitrogen is in the gap between The electrodes should be regarded as an insulator, water is a conductive medium.
Gemäß den Merkmalen des abhängigen Anspruchs 2 soll der Sensor im unteren Bereich des Gasraums angeordnet sein. Hieraus ergibt sich der Vorteil, dass bereits bei kleinen Wassermengen, welche in den Gasraum eindringen, ein Wassereintritt festgestellt werden kann, so dass der Sensor frühzeitig einen Defekt signalisiert.According to the characteristics dependent Claim 2, the sensor is arranged in the lower region of the gas space be. This results in the advantage that even at small Amounts of water that penetrate into the gas space, a water entry detected can be so that the sensor signals a defect early.
Gemäß den Merkmalern des abhängigen Anspruchs 3 ist der Sensor am Anschlussventil zum Befüllen des Gasraums angeschlossen. Somit kann der Sensor auch an Membranausdehnungsgefäße gemäß dem Stand der Technik nachträglich installiert werden.According to the features of the dependent claim 3, the sensor is connected to the connection valve for filling the gas space. Thus, the sensor can also on membrane expansion vessels according to the state the technology later be installed.
Gemäß den Merkmalen des abhängigen Anspruchs 4 ist die Überwachungselektronik mit einer Vorrichtung zur Ausgabe des Fehlers verbunden. Hierzu kommen mehrere Dinge in Betracht. So kann einerseits an dem Wassergerät, vorzugsweise Heizgerät, welches mit dem Membranausdehnungsgefäß verbunden ist, direkt eine akustische oder optische Ausgabevorrichtung vorhanden sein. Hierdurch kommt es beispielsweise zu einem Piep-Ton oder einer Anzeige auf einem Display, z.B. „Bitte Membranausdehnungsgefäß überprüfen". Ferner kann die Überwachungselektronik auch über eine Telefonleitung oder eine andere Art der Datenübertragung mit einem Externen verbunden sein. Hierdurch ist es möglich, dass ein Servicetechniker eine Information erhält, dass bei einem bestimmten Kunden das Membranausdehnungsgefäß zu reparieren ist.According to the characteristics dependent Claim 4 is the monitoring electronics connected to a device for outputting the error. For this Several things come into consideration. Thus, on the one hand on the water device, preferably Heater, which is connected to the membrane expansion vessel, directly one acoustic or optical output device may be present. This comes for example, to a beep tone or a display on a display, e.g. "Please check diaphragm expansion vessel." Furthermore, the monitoring electronics also over a telephone line or other type of data transmission be connected to an external. This makes it possible that a service engineer receives information that at a certain Customers to repair the diaphragm expansion vessel is.
Es ist eine alternative Überwachungsmethode denkbar. Hierbei ist die Membran zwischen dem Gasraum und dem Wasserraum zumindest partiell elektrisch beschichtet. In der Nähe der beschichteten Membran befinden sich zwei Elektroden. Wölbt sich die Membran vom Wasserraum in Richtung Gasraum, so schließt die beschichtete Membran den Spalt zwischen den beiden Elektroden. Ein Stromstoß ist die Folge, der Rest ist analog zu dem zuvor beschriebenen Lösungsprinzip zu sehen.It is an alternative monitoring method conceivable. Here, the membrane between the gas space and the water space at least partially electrically coated. Near the coated membrane There are two electrodes. bulges If the membrane moves from the water space towards the gas space, then the coated closes Membrane the gap between the two electrodes. A surge is the Result, the rest is analogous to the previously described solution principle to see.
Die Erfindung wird nun anhand der Zeichnungen detailliert erläutert. Hierbei zeigenThe The invention will now be explained in detail with reference to the drawings. in this connection demonstrate
