Evaluation of pump characteristic from measurement of fast deceleration

Evaluation of pump characteristic from measurement of fast deceleration

Article describes an experiment where a pump connected to the simple hydraulic circuit is decelerated. Since the deceleration is fast enough the operating point of the machine moves from the initial steady position to the breaking zone, turbine zone and back to the new steady position. A dependence...
