Description
Zusatzanmeldung zur Patentanmledung P 16 98 059.9.Additional application to patent application P 16 98 059.9.
Gas- und Flüssigkeitszähler Das Eauptpatent DBP ... betrifft einen Gas- und Plüssigkeitszähler mit einem durch die kinetische Strömungsenergie des Strömungsmediums in Bewegung gesetzten Meßflügel-Laufrad und einem Kontrollgerät zur ununterbrochenen Meßgenauigkeitsüberwachung.Gas and liquid meters The main patent DBP ... concerns one Gas and liquid meter with a through the kinetic flow energy of the Flow medium set in motion measuring vane impeller and a control device for uninterrupted measurement accuracy monitoring.
Derartige Turbinenzähler erfassen über einen bestimmten Meßquerschnitt unmittelbar die Geschwindigkeit des Strömungsmediums, wobei diese und die tinkelgeschwindigkeit des mit dem Strömungsimpuls beaufschlagten Meßflügel-Laufrades verhältnisgleich sind.Such turbine meters record over a certain measuring cross-section directly the speed of the flow medium, this and the angular velocity of the measuring vane impeller charged with the flow impulse is proportional are.
Die Anzahl der Umdrehungen des Meßrades entspricht bestimmbaren Volumeneinheiten, welche mittels geeigneter Einrichtungen in einer dem Betriebszweck angepaßten Weise registriert werden.The number of revolutions of the measuring wheel corresponds to determinable volume units, which by means of suitable facilities in a manner adapted to the operational purpose be registered.
Strömungsmesser der beschreiebenen Art haben den Nachteil, daß sie Meßfehler aufweisen können, die während des Betriebes nicht oder nur schwer erkennbar sind. Das schnelle Erkennen eines Meßfehlers ist jedoch dann von Bedeutung, wenn der angezeigte Meßwert die Grundlage von sicherheitstechnischen und kommerziellen Maßnahmen ist. Nicht erkennbare Meßfehler können vor allem dann auftreten, enn sich das Verhältnis von Stoffgeschwindigkeit zur Winkelgeschwindigkeit des Meßrades ändert. Die Ursachen solcher Änderungen sind meist Beschädigungen des Getriebes (Meßrad, Lager) oder Ablagerungen von Trennstoffen, weldhe eine Veränderung des vorerwähnten Meßquerschnittes bewirken. Ein zusätzliches Kontrollgerät zur laufenden Überwachung der Meßwerte ist daher in vielen Fällen sehr wichtig.Flow meters of the type described have the disadvantage that they Can have measurement errors that are difficult or impossible to detect during operation are. However, the quick detection of a measurement error is important when the displayed measured value the basis of safety and commercial Action is. Measurement errors that cannot be recognized can primarily occur if they are the ratio of material velocity to the angular velocity of the measuring wheel changes. The causes of such changes are usually damage to the gear unit (measuring wheel, Bearings) or deposits of separating substances, which are a change in the aforesaid Cause measuring cross-section. An additional control device for ongoing monitoring the measured value is therefore very important in many cases.
Das erfindungsgemäße Kontrollgerät besteht aus einem zweiten nachgeschalteten und unabhängig meßenden Turbinenzähler, der mit dem Zählwerk des ersten Turbinenzählers mittels eines Differentialgetriebes (Planetengetriebes) mit Signalgeber verbunden isto Der Zeiger des Signalgebers kann auch, mit oder ohne Fernbetätigung, Signaleinrichtungen betätigen.The control device according to the invention consists of a second downstream and independently measuring turbine counter, which is connected to the counter of the first turbine counter connected to the signal transmitter by means of a differential gear (planetary gear) isto The pointer of the signaling device can also, with or without remote control, signal devices actuate.
In Abwandlung des Erfindungsgedankens können Drehzahlunterschiede der beiden Turbinenzähler auch durch bekannte elektrische bzw. elektronische Geräte erfaßt werden.In a modification of the inventive concept, speed differences can of the two turbine meters also by known electrical or electronic devices can be detected.
Nachfolgend wird ein Ausführungsbeispiel der Erfindung in der Zeichnung näher erläutert und beschrieben.An embodiment of the invention is shown in the drawing explained and described in more detail.
Das Strömungsmedium strömt in Richtung des Pfeils 1 durch zwei hintereinander geschaltete, unabhängig voneinander arbeitende Turbinenzähler 2 und 3, zwischen denen feststehende Strömungsrichter 4 angeordnet sind.The flow medium flows in the direction of arrow 1 through two one behind the other connected, independently working turbine meters 2 and 3, between which fixed flow straighteners 4 are arranged.
Die Winkelgeschwindigkeiten beider Turbinenzähler sind der StrömungsgeschwIndigkeit proportional, so daß die Drehgeschwindigkeiten der Zählwerke 5 und 6, ggfs. mittels Justiermaßnahmen, synchronisiert werden können0 Die Zählwerke 5 und 6 sind mittels eines Ausgleichsgetriebes miteinander verbunden, so daß bei einwandfreier Furktion des gesamten Yeßwerkes von dem Ausgleichsrad 7 keine Bewegung auf die Planetenachse 8 und den Zeiger 9 übertragen wird.The angular velocities of both turbine meters are the flow velocity proportional, so that the rotational speeds of the counters 5 and 6, if necessary. By means of Adjustment measures that can be synchronized 0 Counters 5 and 6 are by means of a differential gear connected to each other, so that with perfect furktion of the entire Yeßwerkes from the balance wheel 7 no movement on the planetary axis 8 and the pointer 9 is transmitted.
\iird jedoch während des 3etriebes das bestimmte und einjustierte Verhältnis der Winkelgeschwindigkeiten der Ke3-räder 2 und 3 bzw. der Zählwerke 5 und 6 durch irgendeinen Einfluß irgendwie gestört, so wird ein dadurch bewirkter Meßfehler durch Ausweichen des Zeigers 3 angezeigt und erkennbar gemacht.However, this is determined and adjusted during operation Ratio of the angular speeds of the Ke3 gears 2 and 3 or the counters 5 and 6 are somehow disturbed by some influence, one is caused by it Measurement errors indicated and made recognizable by avoiding the pointer 3.
Das Erfassen von Drehzahlunterschieden kann auch, was in der Zeichnung nicht dargestellt ist, auf elektrischem bzw. elektronischem Wege erfolgen. Ebenso kann der Zeiger 9 in Abwandlung der dargestellten Ausführungsform eine fernbetätigte Bignaleinrichtung betätigen.The detection of speed differences can also, what in the drawing is not shown, be done electrically or electronically. as well In a modification of the embodiment shown, the pointer 9 can be a remote-controlled one Operate the signaling device.
