Abstract

Den foreliggende oppfinnelse angår pumper som omfatter drivorganer til drift med variabel frekvens, og fremgangsmåter til drift av slike pumper. Fremgangsmåten ifølge oppfinnelsen til drift av en pumpe (1) omfatter følgende trinn: å skaffe verdier for pumpens driftsparametere, som angir pumpetilstander, og overføre verdiene for driftsparametrene fra drivorganene (2) til drift med variabel frekvens til en styreinnretning (11), og bestemme om en på forhånd fastlagt betingelse er oppfylt, å overføre instruksjoner fra styreinnretningen (11) til drivorganene (2) basert på oppfyllelsen av den på forhånd bestemte betingelse. Videre er det beskrevet et datamaskinprogramprodukt som kan lastes ned på minnet i en digital datamaskin, og som innbefatter mykvarekode-deler til å utføre fremgangsmåten ifølge oppfinnelsen, en pumpe (1), et pumpesystem og en styringsinnretning (11) for en pumpe.The present invention relates to pumps comprising variable frequency drive means and methods for operating such pumps. The method of the invention for operating a pump (1) comprises the following steps: obtaining values of the pump operating parameters, indicating pump states, and transmitting the values of the operating parameters from the drive means (2) to variable frequency operation to a control device (11), and determining if a predetermined condition is fulfilled, to transmit instructions from the control device (11) to the drive means (2) based on the fulfillment of the predetermined condition. Further, there is disclosed a computer program product which can be downloaded to the memory of a digital computer and which includes software code parts to perform the method of the invention, a pump (1), a pump system and a control device (11) for a pump.
