Keywords:
Control Oil Pump, Hydraulic Efficiency, Mechanical Efficiency, Darcy–Weisbach Equation, Frictional Head LossesAbstract
The objective of this research is to analyze the power and efficiency of the control oil pump (COP) at the Derna steam power plant, focusing on calculating frictional head losses (Hƒ), volumetric flow rate, and mass flow rate within the pipeline system. The evaluation is based on a computational model and empirical correlations to support performance monitoring and propose maintenance strategies to mitigate degradation caused by aging and operational challenges. Pumping Power Calculator V3.0 and Rotor Zone – Pump Size were employed to simulate hydraulic shaft, and motor power, enabling an assessment of efficiency and performance curves. frictional head losses were calculated using the Darcy–Weisbach (D-W) equation, and the corresponding head loss percentage (Lƒ %) was determined. Results show that hydraulic power was limited (0.33 KW for mass flow, 0.29 KW for volumetric flow, Hƒ = 0.8 m, Lƒ = 0.2%), while mechanical efficiency remained stable at 78%, indicating effective energy transfer despite low hydraulic performance. The results highlight the significance of optimizing hydraulic pathways and implementing predictive maintenance for the sustainable pump operation of pump.
