Abstract: The results of computer calculation of the pressure distribution of the fluid flow on the surfaces of the impeller blades at different rotational speeds of the rotor shaft of a centrifugal pump were presented in the article. It is noted that on the suction face of the impeller blade, the pressure increases at a distance from the inlet to the diffuser. At the back face of the impeller blade, the pressure increases to the middle of the chord length of the element and decreases to the diffuser. At the same time, this effect is not observed at low rotational speeds of the rotor shaft of the centrifugal pump. Also, recommendations are given on the performance of the centrifugal pump in terms of mass flow rates at different rotational speeds of the rotor shaft.
Key words: centrifugal pump, pressure, blade, surface, rotation, mass flow rates.
