Abstract

The system automatically controls the operation of electrically-driven centrifugal pumps in a station with a small reservoir. The pumping sets are switched on by pressure-operated contactors and are switched off by other such contactors where the frequency of starts is below a predetermined value, and by timer contactors where it is above this value. To even out the duty over all sets, they are set to work in a permutation pattern. Each time one set is switched on the next permutation is prepared, and each time one is switched off the prepared pattern is put into effect.
