К причинам порывов водопроводных систем при пусках электроприводов насосных агрегатов

Abstract

The frequency-regulated electric drive of pump installation modelling in a condition of hydraulic blow with representation of a hydrohighway by a line with the distributed parameters is executed. It is investigated influences of narrowing of the pipeline on pressure throws at start-up of pump units electric drives. The conclusion is drawn on expediency of smooth start-up system use in the electric drive of the pump unit.
