Das Hauptpatent 1150 248 betrifft eine Einrichtung zur Anzeige von Undichtheiten an Lagerbehältern für Flüssigkeiten oder Gase» die mit einer Blase aus lagerstoffestem, gasdichtem and flexiblem Kunststoff ausgekleidet oder umhüllt sind. An den Zwischenraum zwischen Kunststoffblass und starrer Behälterwand ist eine Vakuumpumpe ständig angeschlossen, ein Druckmesser ist zur Überwachung des Unterdruckes vorgesehen, und eine Einrichtung zur druckabhängigen Einsatzregelung der Vakuumpumpe bewirkt, daß diese den Druck im Wandzwischenraum, soweit er infoige unvermeidlicher und unschädlicher kleiner Undichtheiten absinkt, selbsttätig innerhalb eines bestimmten Unterdruckbereiches (Unierdrucksollwert) hält. Dabei sind Mittel vorgesehen, die eine Verzögerung oder ein Ausbleiben der Herbeiführung des Unterdrucksollwertes im Wandzwischenraum als Kriterium einer Leckage anzeigen.The main patent 1150 248 relates to a device to indicate leaks in storage containers for liquids or gases »which are made with a bubble are lined or encased in gas-tight and flexible plastic that is most stable in storage. To the space in between between blown plastic and rigid container wall a vacuum pump is constantly connected, a pressure gauge is used to monitor the negative pressure provided, and causes a device for pressure-dependent control of the use of the vacuum pump, that this the pressure in the wall space, as far as it is more inevitable and harmless small leaks drops automatically within a certain negative pressure range (low pressure setpoint) holds. Means are provided which delay or prevent the induction of the negative pressure setpoint in the wall gap as a criterion for a leak.

Eine solche Einrichtung wird durch die vcrliegeade Erfindung weiter ausgestaltet. Um zu verhindern, daß die Leckanzeige und/oder die Abschaltung der Vakuumpumpe unterbleiben, wenn ein Leck vorhanden ist, durch das eine Gasmenge einströmt, die etwa der Fördermenge der Vakuumpumpe entspricht, ist erfindungsgemäß in dem elektrischen Stromkreis des Antriebes der Vakuumpumpe ein Zeitschalter derart angeordnet, daß er gleichzeitig mit dem Ablauf der Vakuumpumpe aus seiner Nullstellung gestartet wird und bei einer wesentlichen Verzögerung des durch den druckabhängigen Einsatzreglers zu bewirkenden Ausschaltvorganges seinerseits den Stromkreis unterbricht und/oder ein Signal auslöst.Such a device is further developed by the present invention. In order to prevent the leakage indication and / or the shutdown of the vacuum pump from occurring if there is a leak through which an amount of gas flows in which approximately corresponds to the delivery rate of the vacuum pump, according to the invention a timer is arranged in the electrical circuit of the drive of the vacuum pump that it is started from its zero position at the same time as the vacuum pump expires and, in the event of a significant delay in the switch-off process to be effected by the pressure-dependent application regulator, in turn interrupts the circuit and / or triggers a signal.

Die Zeiteinstellung des Zeitschalters muß so bemessen sein, daß weder eine Unterbrechung des Stromkreises noch eine Signalauslösung bewirkt werden, wenn die Pumps die normale Evakuierung innerhalb eines vorbestimmten Zeitraumes durchführt, in dem der im wesentlichen gasdächte Bezugsraum nach einem z. B. durch unschädliche Porösität bedingten allmählichen Ansteigen des Druckes bis ze dem Einschalidruck des Druckreglers wieder auf den Unterdrucksollwert evakuiert wird. Nur wenn dieser normale Evakuierungszeitraum bedeutend überschritten, also beispielsweise verdoppelt oder vervielfacht wird, soll der Zeitschalter, der stets gleichzeitig mit dem Anlauf der Pumpe gestartet wird, also die Zeitmessung beginnt, den elektrischen Stromkreis der Vakuumpumpe unterbrechen und/ oder Alarm geben.. Nach dem Anhalten der Pumpe wird der Zeitschalter wieder in seine Nullstellung gebracht.The time setting of the timer must be measured in this way ensure that neither an interruption of the circuit nor a signal triggering are effected, if the pumps perform normal evacuation within a predetermined period of time, in which the essentially gas-roofed reference room after a z. B. by harmless porosity caused a gradual increase in pressure up to the switch-on pressure of the pressure regulator the vacuum setpoint is evacuated. Only if this normal evacuation period is significantly exceeded, for example doubled or is multiplied, the timer, which always starts at the same time as the pump starts, should will, i.e. the time measurement starts, interrupt the electrical circuit of the vacuum pump and / or give an alarm. After the pump has stopped, the timer returns to its zero position brought.
