FIELD: engines and pumps.
SUBSTANCE: present invention relates to a method of controlling the rotational speed of a centrifugal pump operated in an open hydraulic circuit, at which the pump control system regulator calculates the specified pump drive speed taking into account the set and actual head values, as well as the actual speed, note here that said controller takes into account a correction factor to describe geodetic altitude.
EFFECT: disclosed is a method of controlling rotation frequency of a centrifugal pump.
