Machine diagnostics

For years, GMBU has been developing measurement methods for the detection of AE that occur in lubricated tribocontacts (e.g. in bearings and tooth flanks) as well as during cavitation in pumps, turbines and turbomachinery.The recording of acoustic emissions (AE)

The GMBU tribosensor concept (DE 10 2014 103 231) was developed to record acoustic emissions (AE), in which a sensor is placed in close proximity to a lubricated sliding friction contact.The concept was developed on a tribometer (Download four-ball

Cavitation is a common phenomenon which appears in e.g.pumps, turbines, fluid valves and nozzles. In the short term this leads to a drop in discharge, flow rate limitation and in the long term to abrasive erosion on pump blades

GMBU Halle e.V. has been working on the development of vibroacoustic methods for analysing triboprocesses and cavitation in the running machines for almost 20 years. The concepts should support fault diagnostics and fault condition prognosis. The approach correlates (faulty)
