Abstract
El actual trabajo de título tiene como objetivo diseñar un plan de mantenimiento para equipos críticos en una planta de adhesivos, con la intención de disminuir las paradas no programadas. Se definen objetivos específicos a conseguir, además de una metodología de trabajo que permitirá alcanzar los objetivos definidos.
El desarrollo de este trabajo comienza con el levantamiento de la información de la empresa para contextualizar el rubro, su estrategia y misión, luego de esto se realizó un levantamiento a nivel operacional y de maquinaria, para tener la claridad de los procesos, de los equipos existentes en las distintas plantas, obteniendo como resultado un listado de equipos.
Luego se procede a estudiar la criticidad en tres niveles, por planta, por equipos y por componentes con herramientas entregadas por las normas ISO 31.000 e ISO 31.010, utilizando matrices de riesgo y análisis FMECA a cada uno de los componentes del listado obtenido en el levantamiento, clasificándolos como críticos, semi críticos y poco críticos, para que al momento de desarrollar el plan de mantenimiento sea posible enfocar de mejor manera los recursos en equipos que tengan el mayor impacto.
Con la clasificación de criticidad realizada se decide utilizar RCM y sus siete preguntas fundamentales a los equipos seleccionados, ya que esta metodología de mantenimiento va en línea con la estrategia de la empresa, como también se ajusta a las herramientas que esta posee.
A continuación, se diseña el plan de mantenimiento, enfocando los recursos en los componentes obtenidos de la jerarquización, obteniendo para cada componente una planilla con las actividades correspondientes y un adicional con los estándares requeridos por algunas de las actividades. Con los planes de mantenimiento se obtienen tres planes matrices anuales, uno por cada una de las zonas abarcadas.
Finalmente se realiza un análisis económico que busca comparar la perdida de ingreso por una falla intempestiva con el costo del plan de mantenimiento diseñado, concluyendo que el plan es rentable y trae beneficios económicos y operacionales
The objective of the present work is to design a maintenance plan for critical equipment in an adhesives plant, with the intention of reducing unscheduled shutdowns. Specific objectives to be achieved are defined, as well as a work methodology that will allow to reach the defined objectives. The development of this work begins with the survey of the company's information to contextualize the industry, its strategy and mission. After this, an operational and machinery survey was carried out to clarify the processes and the existing equipment in the different plants, obtaining as a result a list of equipment. Then we proceeded to study the criticality at three levels, by plant, by equipment and by components with tools provided by ISO 31.000 and ISO 31.010 standards, using risk matrices and FMECA analysis to each of the components of the list obtained in the survey, classifying them as critical, semi-critical and less critical, so that when developing the maintenance plan it is possible to better focus resources on equipment that have the greatest impact. With the criticality classification made, it was decided to use RCM and its seven fundamental questions to the selected equipment, since this maintenance methodology is in line with the company's strategy, as well as it is adjusted to the tools it has. Then, the maintenance plan is designed, focusing the resources on the components obtained from the hierarchy, obtaining for each component a spreadsheet with the corresponding activities and an additional one with the standards required by some of the activities. With the maintenance plans, three annual matrix plans are obtained, one for each of the areas covered. Finally, an economic analysis is performed to compare the loss of income due to an untimely failure with the cost of the maintenance plan designed, concluding that the plan is profitable and brings economic and operational benefits
