Aplicación de técnicas de mantenimiento predictivo en el laboratorio LTI de la ESFOT.: análisis de vibración.

Abstract

The objective of this work is to apply a predictive maintenance mechanism (vibration evaluation) to detect early failures in four motors of the LTI-CI Laboratory of ESFOT, monitoring vibrations that present some type of intensity according to the characteristics of the mechanisms at internal level in revolution or rotation. In addition, laboratory guide sheets are elaborated. In order for the student to relate to this technique, the vibration analyzer acquired by the Institution and laboratory guide sheets are used. The work focuses on the use of a predictive maintenance mechanism called vibration analysis or study, because it helps to measure the vibration frequency of rotating machinery that is operating with a degree of intensity. Monitoring the condition (healthy or defective) of four engines of the LTI-CI Laboratory of ESFOT, using the Adash A4900 Vibrio M vibration analyzer, the AC150 accelerometer sensor and the ISO 10816 Permissible Vibration Limits standard. Specifically, the following parameters are analyzed: - When the velocity figure is high there is a possibility of presence of faults (misalignment and unbalance). - Acceleration is analyzed, this refers to bearing failures. Finally, we establish conclusions and recommendations of the work developed during this project.
