Influence of Parameters of Induction Motor-Centrifugal Pump Units with Hydropaths Connected in Series on their Modes

Journal Title: Energy Engineering and Control Systems - Year 2015, Vol 1, Issue 2

Abstract

Using the mathematical model of the pump station power supply system in steady-state modes developed by the author, the influence of the parameters of induction motor-centrifugal pump units with in-series-connected hydropaths of the pumps on their steady-state modes was studied. A comparison was drawn on the operation of a number of coupled units with different pump ratings. It was revealed that the difference in rated flow of the operating fluid in centrifugal pumps results in the fact that only the unit with the lowest operating fluid rated flow works effectively. Units with larger rated flow of the operating fluid are underutilized and work with a decreased efficiency in all modes. Viability of applying centrifugal pumps with minimal difference in operating fluid rated flow for induction motor-centrifugal pump units with in-series-connected hydropaths of the pumps was substantiated.
