Zusammenfassung: | FIELD: construction. ^ SUBSTANCE: invention is related to the field of heat and water supply of industrial and housing objects. Method for control of water supply pump electric motor consists in the fact that water head is measured at the pump outlet, measured head is compared to specified value, and deviation of measured head from specified value is minimised by influence at frequency of pump electric motor rotation. At that water flow is measured, and specified head value is formed as sum of minimum head and variable component that is in direct dependence from measured water flow. ^ EFFECT: saving of electric power consumed by pump electric drive by reduction of its wasteful consumption with preservation of comfortable water use conditions. ^ 3 cl, 4 dwg |
