Abstract

PURPOSE:To realize the flow rate simulation in real time and to increase the reliability, by approximating the Q-H characteristics of a pump with plural straight lines in case the simulation is applied to a pressure fluid that flows a pipeline by a pressure fluid supply source. CONSTITUTION:The Q-H characteristic curve of a pressure fluid supply source is shown like A, where the flow rate of the pressure fluid which flows a pipeline by a pressure fluid supply source is Q and the lift of the said supply source is H. This characteristic curve A is approximated with straight lines X1-X2 and X2-X3 to carry out the simulation of flow rate in real time. First, the pressure fluid given from a pump feeds back the flow rate Q and compares it with the flow rate QC which is previously decided, and the pump characteristics is approximated with the straight line X1-X2 in the case of Q>=QC. While the approximation is done with the straight line X2-X3 in the case of Q>QC, respectively. Both equations of the lines X1-X2 and X2-X3 are obtained by the explanation of the simultaneous equations.
