AP19177970 — Improvement of the technology for manufacturing a pump part body from fiberglass
The goal of the project increasing the efficiency of machine-building enterprises due to the development of new technology for manufacturing the bodies of centrifugal pump parts using fibers and composite materials with improved characteristics and appropriate operating conditions.
The relevance of the project is due to the fact that fiber fibers in concrete have high indicators on such characteristics as tensile strength, bending, cutting, impact and fatigue strength, scratch resistance, frost resistance, water resistance, heat resistance and fire resistance. In addition, the distinguishing characteristics of fibers are high anisotropic and discrete values. Here, such features allow to single out fiberglass into an independent group of structural materials with different structural features and properties.
The proposed project is designed to solve these problems by searching new composite materials with special properties as well as technology and application of their production, which is especially urgent.

Results obtained: As a result of the project, a scientifically grounded method for designing three-component fillers for carbon fiber-reinforced composites was developed and experimentally validated. Optimization of filler particle sizes enabled improved material density and mechanical strength. Casting was identified as the most efficient method for manufacturing centrifugal pump housings, and optimized mold designs were proposed. Experimental studies led to the development of technological instructions for composite preparation and casting processes. Key parameters affecting mechanical properties were optimized using design of experiments techniques. In addition, a pneumatic start-up assist device for heavy-rotor machines was proposed, demonstrating improved energy efficiency and operational reliability.
