BEAROMOS®2020 BEARing MOnitoring System For oil-lubricated slide bearings www.schaller-automation.com
Detect the onset of bearing damage even before signs of overheating ensures that any radial and axial vibrations of the crankshaft do not damage the sensor. The sensor housing is bolted to the existing cover on the engine frame, which is usually given at the crankshaft center level. Hydrodynamically lubricated slide bearings are designed so that they operate within the fluid friction range. The bearings only move out of this range to mixed friction for a short time in rare cases (e.g. start/stop), and they then see increased wear. BEAROMOS®2020 detects the deviation from normal fluid friction and can, for example, detect an anomaly when mixed Operating ranges of hydrodynamic slide bearings Condition monitoring concept friction occurs while running at constant engine operation to warn of possible acute severe damage in one of the main Development of mechanical failures over time bearings. The BEAROMOS®2020 is an innovative monitoring system for oil- Possible causes prevention Increasing of mixed friction on the corridor withrotating shaftcondition additional include: monitori lubricated slide bearings, which detects the transition from • Detection Particles of mixed lubrication in oil, consequences in journal of cavitation, bearings bearing wear, sliding friction to mixed friction. • Detection geometric of on deviations vibration bearinganomalies journals/shells, etc. If it occurs during nominal bearing operation, this transition can cause incipient bearing damage. Friction Vibrations The innovation in this application uses the physical phenomenon of the “Seebeck effect”, which generates a voltage as soon as 2 Engine condition different metals, normally separated by the oil film, come into ACCOMOS contact with each other. Oil Mist BEAROMOS (OMD) On the first temperature change, a thermoelectric voltage is VN301plus generated, which is detected by the sensor. Prevention Corridor EXPLOSION The system consists of an easy-to-install sensor that can be attached to for example an engine frame, at level of its crankshaft Time end. According to: Tchakoua et al., Energies 7/4, 2014 A shaft is integrated in the sensor, which is bolted to the crankshaft, e.g. using a simple adapter. A built-in compensator SCHALLER AUTOMATION product philosophy Online monitoring of the main bearings of propulsion/ CONFIDENTIAL -1- auxiliary engines Developed in cooperation with RWTH Aachen University, Germany Minimises maintenance costs Very easy to install, also as retrofit Proven faster response than bearing temperature monitoring 2
Software The supplied software uses the sensor signal to display the status of the monitored bearings. Together with the speed detected by the sensor, it is possible to make a statement about the status of how the bearing is running: hydrodynamic friction or mixed friction. Bearing status is displayed as a bar graph (greenyellow) Long-term trends can be shown Records the last transition from hydrodynamic friction to mixed friction with date, time, duration and revolution speed Information about the condition of the bearings concentrated to a minimum Continuously monitors communication between software and sensor via LED indicator. Screenshots can be taken of current display Possible to export the current data content from the graph to a CSV file The transition from hydrodynamic friction to mixed friction and vice versa can also be displayed as an average over time There is a visual status indicator, if threshold value is exceeded Long-term observation of bearing condition is possible Sensor Installation Cover, e.g. of the engine stand Weitergabe sowie Vervielfältigung dieses Dokuments, Verwertung und Mitteilung seines Inhalts sind verboten, soweit nicht ausdrücklich gestattet.
