The number of unscheduled repairs (and consequently operating costs) can be considerably reduced by the implementation of diagnostic systems at factories and depots (in order to evaluate the quality of manufacture and repair of particular assemblies and overall electric multiple unit) and real-time condition monitoring systems for the most important assemblies of electric multiple unit in the field.
Diagnostic stations built on the basis of the COMPACS®-EXPRESS monitoring systems of vibration analysis are extensively used in repair of wheel motor units (WMU) at depots and factories of the country.
COMPACS®-EXPRESS-TR3 is the system for electric multiple unit comprehensive diagnostics after TR3 repair.
The COMPACS®-EXPRESS on-board system is designed for condition monitoring of WMU and bearing boxes of electric multiple units in the course of motion in actual operating conditions. The system concerned enables timely detection of defects emergence or development by displaying them on the screen in the driver's cabin.
