Repotenciación del banco de pruebas de la turbina Pelton del Laboratorio de Turbomaquinaria Hidráulica de la Facultad de Mecánica

Abstract

The objective of this work is to repower the Pelton turbine test bench of the turbo-hydraulic machinery laboratory of mechanics faculty. So, the following procedure was applied, where a technical diagnosis process was carried out on the test bench. A surface coating was applied and a sacrificial anode was implemented to reduce corrosion in the water tank. Then, a penetrating ink test was carried out on the Pelton turbine to find out its current state. After that, preventive and corrective maintenance was carried out on the centrifugal pump. The force sensor was selected and the measuring instruments were recalibrated, achieving at this point the transformation of analog signals to digital, regarding the redesign of the software for data acquisition the LabVIEW program was implemented. Once the surface coating and the sacrificial anode were applied, the corrosion reduction was achieved by 90%, by applying the non-destructive test of penetrating inks. Pelton turbine blades comply with the parameters established for its operation. Once executed maintenance of the pump, a yield of 65% is obtained. It is with either the software redesign to data acquisition. It allowed the deduction, storage and visualization of pressure, flow, speed and force data from the tests carried out. Once its repowering was completed, the pertinent tests were carried out, having flow values of 8,01 liters, speed of 1460,1433 RPM, pressure of 28,038 Mca and a force of 46 N. It is recommended to follow the process diagram and the maintenance plan to avoid equipment damage.
