A GREAT RELIABILITY, CAUSES A DECREASE OF FAILURES IN THE ROTATING MACHINES

Since industrial machines are prone to multiple modes of failures, or the opportunities for breakdowns and incidents are multiple, and given that the operating factors have a random nature, may cause unanticipated cataleptic failures. To reduce overall maintenance costs, the number of unplanned outages, it is necessary to ensure a great reliability, causes a decrease of failures in the rotating machines and to improve the MTBF of the machine. Thus define the maintenance actions to be carried out and the spare part at the appropriate time, or make selective maintenance. That is why, the aim of this work is to use the law of Waloddi Weibull in order to know at all times the reliability, the MTBF and ensure the availability of equipment.
