Modelling of Work of the Rotor-Type Blade Pump with Revolving Stator

Abstract

In the article, the analytical dependences of modelling the cell cross-sectional area between two adjacent blades of a rotary blade pump and capacity for a pump with fixed and rotating stators are given, and analytical dependences are derived to model the power necessary to overcome the friction forces of the blades. The forces acting on the radially placed blade of a rotary pump with a fixed stator (non-rotating or stationary) and a rotating stator are analyzed. Design and technological parameters that influence the pump capacity and power are taken into account. The power required for the movement of the pump blade without taking into account the compression of the air has the opposite character of the change as to the pump capacity The capacity of a rotary pump with a rotating stator is three times higher than that of a stationary stator. The rotary pump with a rotating stator, with six radially spaced blades, consumes 0.854 [kW] less power to overcome the blade friction of 1 313 [kW]. The results of modelling of the pump work are given.

“…Systems that may involve such simultaneous components can be found also in multiphase polymer processing such as injection moulding or cases where two impinging jets collide. Further examples of industrial devices in which domains that have a combination of such rotation and extension components are rotary pumps Dmytriv et al (2021) and cyclone separators Li, Huang & Li (2023).…”
