Test Motors, through its predictive maintenance tool TestIM, allows to detect when the life of a component, in this case the one of the bearing of a turbine-compressor of a client of the chemical sector, has been terminated, and it allows to know when its substitution. It is a turbine-compressor driven by a 250 kW squirrel cage rotor induction motor that is started to be monitored at the end of 2015.
Causes of the fault
The reason for this failure is due to the fact that the machine has stopped for several months, and this has generated a "maintenance" defect in the bearing assembly. It is a machine of little use, and failing to perform the optimum operating conditions for which it has been designed, the components have ended up failing.
