METHOD OF PUMP CONTROL Russian patent published in 2019 - IPC F04D15/00 F04D13/12 G05B13/02 

FIELD: pumps building.

SUBSTANCE: group of inventions relates to control of operation of a pumping system (HC), pump units (HA) of which, for example on areas of fountains, can be put into operation in different quantities and operated with different number of rotations. Control method of HA for control of operation of HC with at least two HA (2), installed between each other in parallel or in series, includes: determination of specific consumed total power E_S the entire HC, which determines total power relative to the total hydraulic load of the entire HC; determining specific specific power E_P,n each HA (2), determining individual consumed power relative to individual hydraulic load of corresponding HA (2); calculation of individual coefficient E_gain,n loads for each HA (2) according to equation E_gain,n = E_S/E_P,n; adaptation of individual hydraulic load (Q_n; H_n) AT (2) depending on the desired hydraulic load, as well as on the individual coefficient E_gain,n load of corresponding HA (2); as well as individual control for each HA (2) of individual hydraulic load (Q_n; H_n).

EFFECT: inventions are aimed at provision of energy-optimum mode of several HA operation.
