On-Line Diagnosis and Energy Assessment of Centrifugal Pumps under a Thermodynamic Approach Method


Background/Objectives: The implementation of a novel method for the characterization of energy efficiency in centrifugal pumps based on the first law of thermodynamics is studied, with which the energy consumption of the turbomachine can be diagnosed. Methods: With the measurement of temperature and pressure at the inlet and outlet of the pump, energy efficiency is determined, without the need to measure electrical or mechanical parameters, which allows determining quickly on site if the pump is operated in an area of high efficiency. Findings: The results allow corroborating the high predictive capacity of the proposed methodology so that the trend is followed compared with efficiency data calculated by conventional methods. A deviation close to 1% was observed in the average efficiencies, compared with the developed method. Application: To develop an online diagnosis and energy assessment of Centrifugal Pumps based on the thermodynamic Approach Method.
