Repotenciación y calibración del banco de pruebas de la turbina hélice de eje horizontal del laboratorio de turbomaquinaria hidráulica de la Facultad de Mecánica

Abstract

The objective of this research work was the repowering and calibration of the test bank of the horizontal axis propeller turbine of the Hydraulic Turbomachinery Laboratory of Mechanics at Escuela Superior Politécnica de Chimborazo. The technical diagnosis of the faults was developed, which allowed defining the parameters of automation, preventive and corrective maintenance. The repowering was carried out through the implementation of anticorrosive methodologies following the guidelines of the ISO 12944 Standard, for which anticorrosive paint was applied to the water tank. In addition, the ASTM B 843 Standard was applied, which is based on magnesium anode protection, and the ASTM E 165-18 Standard, that supports the application of tests with penetrating liquids. Subsequently, the calibration and corrective and preventive maintenance of parts and accessories were carried out. For automation, LabVIEW version 2020 software was used, which facilitated the operation of the system. It is concluded that the test bank fulfills its required function and that the application of automation parameters collected and processed the variables to be measured. Therefore, the technician in charge of the laboratory is recommended to periodically review the maintenance plan and carefully handle parts, elements and the control panel to avoid problems in their operation.
