Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Regelung verschiedener Betriebsparameter, insbesonde­ re der Förderhöhe H, des Förderstroms Q, des Leistungsbe­ darfs P und der Drehzahl n, bei Pumpen und Verdichtern, vorzugsweise Kreiselpumpen und Ventilatoren. The invention relates to a method and a device to control various operating parameters, in particular re the head H, the flow Q, the performance P and speed n, for pumps and compressors, preferably centrifugal pumps and fans.

Nach dem bekannten Stand der Technik werden die Regelgrößen für eine Regelung des Förderstroms Q und der Förderhöhe H im Fördermedium selbst gemessen. Die Meßfühler unterliegen an ihrem Einsatzort starken Bean­ spruchungen und verursachen durch die aufwendige Meß­ technik erhebliche Kosten. Die Erfindung löst diese Probleme dadurch, daß die Regelung nach Kennlinien der Betriebs­ parameter gemäß der gewünschten Betriebsart erfolgt, wobei die Messung einzelner Betriebsparameter zur Berech­ nung der Stellgröße außerhalb des Fördermediums erfolgt. Zweckmäßigerweise werden die Drehzahl n und der Lei­ stungsbedarf P als elektrische meßgrößen zur Beschreibung der Kennlinien verwendet. Die ermittelten Kennlinien bzw. Kennfelder werden in einen Rechner fest einprogrammiert. According to the known prior art Control variables for controlling the flow rate Q and Head H measured in the medium itself. The Sensors are subject to strong bean at their place of use spells and cause by the elaborate measurement technology considerable costs. The invention solves these problems in that the control according to the operating characteristics parameters according to the desired operating mode, the measurement of individual operating parameters for calc The manipulated variable takes place outside the medium. The speed n and the lei are expediently Power requirement P as electrical parameters for description the characteristics used. The determined characteristic curves or Maps are permanently programmed into a computer.
