Development of hardware system using temperature and vibration maintenance models integration concepts for conventional machines monitoring: a case study

Abstract

This article describes the integration of temperature and vibration models for maintenance monitoring of conventional machinery parts in which their optimal and best functionalities are affected by abnormal changes in temperature and vibration values thereby resulting in machine failures, machines breakdown, poor quality of products, inability to meeting customers' demand, poor inventory control and just to mention a few. The work entails the use of temperature and vibration sensors as monitoring probes programmed in microcontroller using C language. The developed hardware consists of vibration sensor of ADXL345, temperature sensor of AD594/595 of type K thermocouple, microcontroller, graphic liquid crystal display, real time clock, etc. The hardware is divided into two: one is based at the workstation (majorly meant to monitor machines behaviour) and the other at the base station (meant to receive transmission of machines information sent from the workstation), working cooperatively for effective functionalities. The resulting hardware built was calibrated, tested using model verification and validated through principles pivoted on least square and regression analysis approach using data read from the gear boxes of extruding and cutting machines used for polyethylene bag production. The results got therein confirmed related correlation existing between time, vibration and temperature, which are reflections of effective formulation of the developed concept.

Development of a Low-Cost Vibration Measurement System for Industrial Applications

“…The tests confirmed the stability and reliability of the system for a frequency range up to 5 kHz. Adeyeri et al [12] presented their development of a system using vibration and temperature maintenance models integrating concepts for machine monitoring. Their system is based on an 8-bit microcontroller and records vibration and temperature measurements.…”

Design and manufacturing of an ultrasonic reactor for biodiesel obtaining by transesterification

“…A variable of interest is the temperature value of the process inside the transesterification tank, since depending on the type of raw material to be used, the value of the reaction temperature must acquire a different value. The module is powered at Vdc, it has as input the temperature inside the tank, and as output the normalized temperature signal, captured by a thermocouple type K and conditioned by the integrated circuit AD595 [40], which allows interaction with the controller module, who later performs the visualization process.…”

A maintenance system model for optimal reconfigurable vibrating screen management

“…Makinde et al (2016b) also discussed an IEAPMS (intelligent e-assessment and prognosis management system) e-maintenance framework and an e-machine temperature monitoring algorithms that could be used in optimally maintaining and preserving the functionality of different machines used in a manufacturing industry. Adeyeri et al (2016) investigated the potential of using temperature and vibration models to monitor the performance of conventional machines, in which their functionalities are hampered by abnormal changes in temperature and vibration values. The study established that increment in the operating temperature and vibration of different subsystems of a machine results in a rapid decline in machine reliability.…”
