Propuesta de un plan de gestión de mantenimiento preventivo para los equipos principales del horno de clinker en INVECEM S.A. Planta Cumarebo

Abstract

Maintenance is the dynamic implemented on the set of components and elements that help guarantee the availability of their operation in the production lines. In the Venezuelan Cement Industry (INVECEM S.A.) Cumarebo Plant, it has a wide variety of mechanical and electrical equipment, which makes up the Clinker production system in the kiln area. Currently, these equipment present a high number of unforeseen failures, which, causing a decrease in Clinker production, this deficiency in the performance of the equipment is due to lack of preventive maintenance. Therefore, the objective of this project is to propose the design of a preventive maintenance plan for critical equipment. For which the current state of the equipment was diagnosed, the possible failures and consequences thereof were analyzed, allowing the equipment to be determined to be in critical condition. The research modality is feasible project type, the paradigm is positivist, being a documentary and non- experimental research. The Jack Knife diagram technique and the Failure Modes and Effects Analysis (FMEA) method were applied to estimate the impact and consequence of possible failures, showing that the Clinker cooling system had a number of twenty-seven (27) failures and five hundred thirty-seven (537) accumulated hours, the component of the cooling system that is in critical condition is the hydraulic unit (CU.471-UH1) for which a plan was designed preventive maintenance and a spare parts request registration model, which would improve the availability of the equipment, reduce the number of stoppages, and increase the efficiency of the system, to increase Clinker's production capacity.
