Análisis de la confiabilidad y disponibilidad de la línea de extrusión de 160 a 250 mm de la empresa Tigre Ecuador.

Abstract

This project analyzed confiability and disponibility of Tigre Ecuador´s PVC pipes extrusion line for diameters from 160 to 250 mm, using RCM (Reliability Centered Maintenance) metodology and applying a machine failure analysis, with the aim to incorporate an Structured & Systematic Maintenance approach, applicable to the company. The steps to reach this objective have been stablished as follows: First, the machines and equipment which conform the productive systems and the extrusion lines as a whole, have been identified,where, all the machinery has been divided in primary and secondary subsystems according with their function. Secondly, the equipment working principles have been studied and analyzed for make a complete machine failure analysis, and create a maintenance plan with the tasks frequency, schedule and guidance of all maintenance work activities Finally, several recommendations and conclusions in order to improve the company’s productivity and efficiency have been made, where we can find: an spare parts- list as guidance for all the machinery systems and sub-systems, predictive maintenance techniques for expecting a disponibility and confability rise on the 160 mm - 250 mm diameter extrusion line.
