Schaller Automation are experts on oil mist formation inside crankcases and analysing its source in order to propose a technical solution to the market.
Schaller Automation developed Bearomos®2020 in cooperation with the RWTH Aachen University (Germany) within a public funded project financed by the ZIM programme (“Central Innovation Programme for small and medium-sized enterprises”) to detect the beginning of a lubrication failure far earlier than conventional sensors such as bearing temperature sensors.
Every second counts when it comes to safeguarding the engine crankshaft’s main bearings at the moment of a bearing failure. Bearomos®2020 can detect the very first metal-to-metal contact, even before mechanical damage has occurred, avoiding expensive crankshaft damage or engine downtime.
The Bearomos®2020 system’s software provides the operator with live signals and information about the monitored bearings. Together with the shaft speed, also given by the sensor, it is possible to make a statement about how the bearing is running: liquid friction or mixed friction.
The beginning of a friction problem within an oil-lubricated slide bearing always comes along with the bearing’s regular change from liquid into mixed friction. The system is ideal for being retrofitted to existing engines as a single sensor is enough to monitor the entire line of crankshaft main bearings.
By installing Bearomos®2020 onboard passenger ships, Schaller contributes to the preventative and predictive maintenance services for engines and any machine equipped with journal bearings.
