AP08857367 — Development of innovative technologies for improving energy efficiency and reliability of centrifugal pumps manufactured in Kazakhstan

The main objective of the project: The goal of the project is to develop innovative technologies for designing and manufacturing centrifugal pumps with impellers that have a modernized heterogeneous impeller grid and are made of modern composite materials. The design of the centrifugal pump with modified impellers will meet modern standards of energy efficiency and reliability.

The relevance of the project: The project idea will be aimed at solving a multicriteria problem consisting in the integration of approaches to improve energy efficiency and reliability of pumping equipment. The methods will include modifying the geometry of the flowing parts, in order to improve the geometry of the flowing part of the pump, which will improve the kinematics of the flow, the homogeneous lattice of the blades will be heterogeneous, changing the properties (modification) of solid surfaces interacting with the pumped liquid by replacing the material of the centrifugal impeller with metal on composite polymers, which will also allow a positive effect on the dynamic characteristics of the pump by reducing the force of imbalance.Previous studies in this area were carried out in the direction of changing the blade geometry to a double curvature blade, or changing the shape of the disks by the “dressing” method, the problems of friction of the flow were solved by applying hydrophobic coatings to the working disks and the channels of the impellers, vibration reduction was carried out by installing dynamic dampers. The idea proposed in the project will reduce the technological chain of impeller modification by one large stage of hydrophobization of a metal impeller. The developed impeller will combine two optimal parameters: geometry and interaction with the pumped medium.

Results obtained: The research developed an innovative approach to upgrading centrifugal pump impellers using polymer-composite materials and a heterogeneous blade system. Hydrodynamic analysis demonstrated improved head and efficiency compared to conventional designs. Numerical modeling and software tools were used to optimize impeller geometry and determine key composite material parameters. Experimental studies confirmed the validity of the developed models and the high mechanical performance of the composite. A laboratory test bench was designed, and hydraulic tests showed good agreement with calculated results. Technologies for 3D printing and molding of composite impellers with optimal properties were established. Overall, the results prove the feasibility of enhancing pump energy efficiency and implementing the developed solutions in industry.
