Abstract
A mathematical model of the starting-up of the centrifugal pump rotor with an asynchronous electric motor has been built as part of a pumping station operating on the grid. The described method takes into account such factors as the pressure loss in the pipeline, inertial pressure occurring during the operation of the pump, the torque of the impeller and the torque of the engine.
The obtained method of dynamic analysis makes it possible to estimate the overheating of the electric motor of a centrifugal pump depending on various factors and, as a consequence, to predict its possible failure.
