Definitions

  • the pressure in the network is sensed by a pressure transducer 13 the output of which is an analogue electrical signal being proportional to the pressure of the compressed medium.
  • the analogue signal is transformed into a digital signal by an analogue to digital converter 12.
  • the digital signal corresponding to the pressure in receiver 14 is supplied to a microcomputer 11, which comprises a microprocessor, memory for storing information about compressor capacities, limit pressures, measured pressures and so on, and drive circuits for actuation of contacts LX and MX.

Claims (3)

1. Verfahren zur Drucksteuerung des verdichteten Mediums aus einer Verdichteranlage mit einer Mehrzahl von Verdichtern (C1, C2, ... CX), die in Parallelschaltung an ein Verteilungsnetz (14) für das verdichtete Medium angeschlossen sind, dadurch gekennzeichnet, daß der Druck in dem Verteilungsnetz (14) mit einer größeren Häufigkeit gemessen wird als die Häufigkeit der Druckschwankungen in diesem Verteilungsnetz, daß jeder Druckmeßwert mit dem vorausgegangenen Druckmeßwert verglichen sowie ein Druckdifferenzwert ermittelt wird, daß der Druckdifferenzwert zu der Kapazität der vorhandenen Verdichter (C1, C2, ... CX) in Beziehung gesetzt wird und dabei die erforderliche Zahl der Verdichter ermittelt wird, durch deren Zu- oder Abschaltung das Vorzeichen des Druckdifferenzwertes umkehrbar ist, daß die Funktionsstellung einer Anzahl von Verdichtern, die um die Zahl 1 kleiner ist als die zuvor ermittelte erforderliche Zahl, verändert wird, wenn der gemessene Druck in einen von zwei vorgegebenen Druckgrenzwerten definierten Bereich fällt, und daß der Funktionszustand eines weiteren Verdichters verändert wird, wenn einer der Druckgrenzwerte erreicht ist.
2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, daß der Funktionszustand einer zur Umkehrung des Vorzeichens des Druckdifferenzwertes erforderlichen Zahl von Verdichtern verändert wird, wenn der gemessene Druck außerhalb des vorgegebenen Bereiches liegt.
3. Verfahren nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß der während des Anlaufens des nächsten Verdichters mögliche Druckabfall vorausberechnet wird und daß der nächste Verdichter ohne Last angefahren wird, wenn der Druckabfall einen vorgegebenen Wert überschreitet.
