Pump installations are critical components in industrial processes, particularly in energy-intensive sectors like ethanol production. This study examines the external influences induced by technological processes, such as variations in water temperature, grain moisture, and pipeline resistance, and their impact on pump performance and energy efficiency. A mathematical model was developed to analyze these interactions, and a simulation model was validated using experimental data from an ethanol production facility.
The results show that water temperature increases of 5°C can reduce energy consumption by 7%, while higher grain moisture content, increasing by 15%, results in a 10% rise in energy consumption due to elevated flow rates and friction losses. These findings highlight the importance of real-time monitoring and adaptive control strategies, such as the use of variable frequency drives (VFDs), which were shown to optimize pump speed and yield energy savings of up to 18%.
This research underscores the need for integrating external factors into pump operation strategies to enhance energy efficiency while maintaining process reliability. Furthermore, the study validates the applicability of the simulation model for predicting pump performance under varying external conditions, with an average deviation of just 4.5% compared to experimental results.
Future research should focus on advanced optimization techniques, such as artificial intelligence-driven control algorithms, and explore the long-term effects of cavitation and other nonlinear dynamics. These approaches will further enhance the energy efficiency of pump systems in industrial applications, promoting sustainable and cost-effective practices in Uzbekistan's growing ethanol production sector.
