Piping Network Analog Apparatus

Abstract: 

Disclosed is an analog apparatus for simulating the low frequency pulsations and surge characteristics of centrifugal compressors and pumps and their interaction with piping systems. The apparatus includes a capacitor pump for simulating the pumping action of a centrifugal compressor. Voltages are applied to the input and output of the capacitor pump that are proportional to the section and discharge pressures of the compressor. The capacitor pump is driven electrically to simulate the action of the centrifugal compressor in a piping network.
