Propuesta de rediseño del circuito eléctrico y de tableros de control con plan de mantenimiento de los sistemas de las áreas de preparación y fabricación de la Planta PISMADE S.A. Riobamba

Abstract

The objective of this work is to prepare an electrical redesign proposal and a maintenance plan focused on reliability for the systems of PISMADE SA, for which an inspection of the state of the wiring and a qualitative evaluation of the panels was carried out, followed by, the new electrical, control and sub-panel circuits were designed under the UNE EN 60617-2 standard. Lastly, parameters and technical data were collected for the calculations and selection of the electrical components. Simultaneously, a maintenance plan was carried out based on the RCM methodology, beginning with the collection of information from 18 systems with their 96 pieces of equipment coded under ISO 14224 standard up to a fourth hierarchical level. Later the technical sheets for the systems and equipment were prepared. In addition, the charts of the operational context and the criticality analysis were prepared qualitatively. Then, the RCM methodology was applied, developing the information sheets detailing the functions, failure modes, failure effects and consequences of the failure of the equipment. To close the decision sheets were made where the tasks for the maintenance plan were obtained, finally a schedule and its logistics required for a year were established. It is concluded that the redesign of the electrical circuit will reduce energy losses, risks to personnel and systems, while the redesign of the control panels will improve and facilitate production operations, in addition to the execution of the maintenance plan is shortened. the most appropriate tasks to attack each of the failure modes and reduce maintenance-related costs up to $18,835,27 dollars. Therefore, it is recommended to install distribution panels for each area and change the current maintenance model to ensure greater availability of the systems.
