FIELD: pumping equipment.
SUBSTANCE: present invention concerns a method for adjustment of a rotational frequency of a centrifugal pump, in which an adjuster of a pump control system calculates a set rotational frequency of a pump drive, taking into account set and actual pressure values, as well as an actual rotational frequency, wherein this adjuster, for determination of a value of an adjusting effect, is based on at least components of the affinity rule, in particular, for calculation of a value of an adjusting effect, it takes a quadratic dependence between a rotational frequency and pressure.
EFFECT: development of a method for adjustment of a rotational frequency of a centrifugal pump.
