Centrifugal pumps are crucial in a variety of industrial sectors, but their performance is often affected by energy inefficiencies, wear-related failures, and suboptimal hydraulic characteristics. This research presents a comprehensive experimental study aimed at optimizing the hydraulic performance, energy consumption, and reliability of centrifugal pumps through design innovations, advanced manufacturing techniques, and predictive maintenance. Computational Fluid Dynamics (CFD) simulations, additive manufacturing, and Long Short-Term Memory (LSTM)-based predictive algorithms were employed. The findings revealed up to a 7.3% increase in hydraulic efficiency, a 75% reduction in failure incidents through predictive maintenance, and 8.2% savings in energy usage. The proposed framework offers a scalable, data-driven approach to improve centrifugal pump operations in modern industrial applications.
Introduction
Centrifugal pumps are crucial in various industries but often face efficiency losses due to hydraulic design flaws, cavitation, and maintenance issues. This study integrates computational modeling (CFD), experimental validation, additive manufacturing, and machine learning-based predictive maintenance to optimize pump performance.
Key points include:
Performance Parameters: Efficiency, flow rate, head, NPSH, and power consumption are critical metrics, with CFD used to analyze internal fluid dynamics and energy losses.
Design Innovations: Advanced impeller designs (curved blades, biomimicry-inspired shapes) and optimized volute casings reduce losses and improve pressure distribution.
Materials and Manufacturing: New materials like carbon fiber composites and 3D printing (DMLS) enable complex, precise, and durable pump components.
Predictive Maintenance: Machine learning models, especially LSTM networks, analyze sensor data to predict failures early, significantly reducing downtime.
IoT and Digital Twins: Real-time monitoring via IoT and digital twins allows better operational control and maintenance planning.
Energy Efficiency: Use of variable speed drives and optimized designs reduce energy consumption by 8–30%, supporting sustainability goals.
Cavitation Mitigation: Improved designs and anti-cavitation features reduce damage, noise, and performance loss.
Experimental and Simulation Results: Optimized impeller designs showed improved hydraulic efficiency (74.7% vs. 67.4%), higher pressure head, reduced power consumption, better cavitation resistance, and extended pump life through predictive maintenance.
Despite advancements, the integration of these approaches into unified frameworks and long-term industrial validations remains limited, highlighting areas for future research.
