Elaboración de guías de laboratorio para el banco oleohidráulico de la división de ingenierías de la Universidad Santo Tomás sede principal

Abstract

This work focuses on the development of laboratory guides for teaching fluid power (oleohydraulic) systems in the training of mechanical engineers, particularly in the field of fluid power systems, where the hydraulic test bench of the School of Engineering at Universidad Santo Tomás (Main Campus) was being used without technical documentation or standardized protocols. The general objective was to develop laboratory guides to standardize the operation, preventive maintenance, and execution of experimental practices of the bench, aligned with the technical competencies required by industry. The methodology was organized into four phases, preceded by a systematic review of the literature and the state of the art: (1) technical characterization of the equipment through a detailed inventory of its components, functions, and specifications; (2) development of standard operating procedures (SOPs) for installation, start-up, calibration, variable measurement, safe operation, and shutdown; (3) design of a preventive maintenance plan with daily, monthly, and annual routines; and (4) structuring of laboratory practices based on ISO 1219 symbology. The results include the complete characterization of the bench —power unit, valves, actuators, instrumentation, and PLC + HMI control system—, eight SOPs, a preventive maintenance plan, and twenty-two laboratory guides (hydraulic, electrical, electro-hydraulic, and proportional). As a product of this theoretical and practical work, a support material is obtained — a laboratory handbook that integrates the operation and maintenance manual of the bench with the catalogue of practice guides—, which fosters consistent learning, optimizes the use of the institutional resource, and extends the equipment’s service life.
